Is there a long-term toxic threat in the ‘environmentally benign’ light bulbs?

Comment by Tom Davey

The Terracotta Army was buried with the Emperor of Qin (Qin Shi Huangdi) in 210-209 BC (his reign over Qin was from 247 BC to 221 BC and over unified China from 221 BC to his death in 210 BC). The Terracotta Army was discovered in March 1974 by local farmers drilling a water well. Mercury was found when the tomb was opened.

ashion is a big industry these days, generating billions in annual revenues as models saunter down the runways showing off the latest clothes. Sometimes I think environmental issues become much like radical chic as the media focuses on the ecological ‘fashion of the month!’

Decades ago, acid rain reigned supreme in the concerns of many environmentalists who were virtually ecological fetuses at that time.

Protesting had not then reached an exalted status as powerful as that of scientists and engineers with credentials. Over time, I’m sure vast areas of forests were felled for the paper required in the coverage of the acid rain phenomenon; indeed, one of my friends won a Governor General’s award for a book on this subject. But one hardly ever hears of acid rain any more.

Then there was the ozone hole in the atmosphere which was accu-

rately described as a real environmental threat. Chlorofluorocarbons were identified as a major culprit.

Another of our friends, a female engineer, did some innovative design work to recapture CFCs from old fridges. Perhaps, more important was a method of recapturing them from the giant coolers on the roofs of supermarkets and other buildings which require huge quantities of CFCs. The good news is that the ozone hole seems to have healed in a relatively short time. I have not seen any recent data on this but assume from the absence of government action, or media coverage, that at least the once terrifying ‘hole’ in the ozone layer has been fully or partially restored.

But new issues come along with increasing speed to dominate the media. Some topics are richly deserving of media coverage, such as the outcry following the deaths and serious injuries from poor water

treatment at Walkerton, Ontario.

Walkerton in fact dominated media coverage for months, including this magazine, I am pleased to say. But clearly some reporters did not understand the reason which led to the tragedy, namely a serious lack of operator training in the water treatment plant. Two operators, the Koebel brothers, were convicted; one served jail time.

Since then various Ontario governments have made efforts to ensure this tragedy will never occur again, leading to the creation of the Walkerton Clean Water Centre.

In recent months there has been a great deal of publicity regarding the use of new types of light bulbs, moving away from the traditional incandescent light bulbs to fluorescent bulbs; this is in pursuit of environmental efficiency. Fluorescent bulbs use less energy than incandescent light bulbs, but at least one expert thinks that the situation should continued overleaf...

Comment by Tom Davey be evaluated as there is mercury in this type of lighting.

(See ES&E April/May 2007 issue. www. esemag.com.)

I wonder if, in the rush to combat global warming, the government’s encouragement to abandon conventional incandescent bulbs to save energy may ultimately be increasing the amount of mercury in the atmosphere. There may only be tiny amounts of mercury in the proposed new light bulbs but mercury is a persistent and durable metal and I wonder what will happen if millions of them ultimately end up in landfill sites - some of which surely must be near or over aquifers which are the source of drinking water supplies.

Mercury is indeed a very durable metal. Recent interest in a few of the fabled Terracotta Warriors from the tomb of the First Chinese Emperor, currently on display in London, England, led to extensive coverage of the Emperor’s remarkable centuries’ old tomb.

When the tomb was unearthed in more recent times, it was found that mercury - undeniably a toxic metal which can be even more toxic if it transforms into methyl mercury – had been used to provide theatrical ‘lakes’ for the departed Emperor’s afterlife.

Despite unprecedented media coverage on environmental issues there remains a deplorable lack of accurate public knowledge of environmental realities. Government reaction frequently results in political public relations exercises rather than viable scientific remedial actions.

This often results in millions of dollars being squandered on impractical - and inevitably expensive projects which do little, or nothing, to mitigate ecological crises. Indeed, political exercises can exacerbate, not eliminate problems. I hope the new light bulbs will not be among them. tom@esemag.com

Letter to Editor It was refreshing to see the editorial comment which reviewed Weird Weather, a most unusual comic book about Global Warming issues. (page 7 November ES&E) Much of today's environmentalism is squeezing humour from the scene so it’s nice to see a magazine where doers stand up against protesters. Grinning isn’t sinning, but when some radical environmentalists raise their green and pointy heads to demand we bow in their direction, it’s getting harder and harder to smile. But humour is what the review of Weird Weather showers upon the dry world of much contemporary Environmentalism.

When humour is verboten on any subject, the chances of society getting the right answers to complex problems are greatly diminished. The way the winds of change are blowing tends to diminish the research, design and implementation skills of qualified environmental professionals whose research and design skills have been saving lives and reducing lethal diseases for over a century. Regrettably, few journalists seem aware of the engineer's role and Weapons of Mass Persuasion are slowly dominating what used to be considered regions of personal opinion.

Keeping humour alive is a defence. Tom Davey stands up and stands out amid the storms of ecological rhetoric. It seems to me there’s a conflict between those who work to help make the world a better place to live in, and those who work to scare. Shakespeare wrote that “All the world's a stage” and perhaps now, the world’s mutated into one big TV screen. Amid the dark shadows which flicker on this screen it is nice to see Environmental Science & Engineering stands up amid the sunlight of humour.

NEWS Water reports offer insight into Alberta's water resources The Alberta government has released two reports that offer insight into the state of Alberta’s water resources and will help inform government and watershed planning and advisory groups for the next 20 years.

As part of Water for Life: Alberta’s Strategy for Sustainability, Alberta Environment sought to determine how much water is needed and used in the province.

The resulting report, Current and Future Water Use in Alberta, provides estimates of water used in the province during 2005, summarized by sector and by river basin. The report found that because Alberta Environment issues water licences to a maximum allocation, actual water use is lower than what has been allocated. The report also includes projections of future water use to 2025.

The second report, Information synthesis and initial assessment of the status and health of aquatic ecosystems in Alberta: surface water quality, sediment quality and non-fish biota, and its accompanying summary report provide an initial assessment of the status of aquatic ecosystems in the province. The report also provides an overview of current knowledge surrounding the province’s major basins and water bodies, including an assessment of water quality. The majority of sites assessed showed ‘excellent’ or ‘good’ water quality and none

Quinte-Eco Consultants fined for submitting false information Ron Carter has been barred from practicing as an environmental consultant for a period of two years and he and his company, Quinte-Eco Consultants Inc., have been fined $84,000, plus a victim fine surcharge, after being convicted on three counts of providing false information to the Ministry of the Environment.

Mr. Carter is the president of QuinteEco Consultants Inc, which operates as an environmental consulting business and is located in Prince Edward County.

In the fall of 2005, he and his company were hired by James Sinclair who was conducting a site decommissioning at 621 Dundas Street East. Mr. Carter was hired to conduct sampling and provide environmental consulting services. On three separate occasions the ministry was advised by Mr. Carter that all samples taken by the company at the site had come back as non-detect for PCBs. The court heard that a provincial officer from the ministry had visited the lab where the company had submitted its samples for analysis. The officer determined that three of the nineteen sample results submitted by the company had in fact tested positive for PCBs. Mr. Carter did not provide details of these three sample results to the ministry and, on

several occasions, had told provincial officers that all sample results had come back as non-detect for PCBs. Mr. Carter and Quinte-Eco Consultants Inc. were charged following an investigation by the Ministry of the Environment’s Investigations and Enforcement Branch.

Calgary firm fined $280,000 for sulphur dioxide release Tiger Industries Limited has been fined $280,000 after pleading guilty to one charge of releasing a substance that causes, or may cause, a significant adverse effect under Alberta’s Environmental Protection and Enhancement Act. The plea stems from an incident in January 2005, involving the release of sulphur dioxide from the company’s fertilizer plant in Calgary’s Foothills Industrial Park.

The release resulted in a large response by city emergency workers and Alberta Environment. Several city emergency response personnel reported adverse health effects related to their exposure to the gas. One was treated in hospital and several others reported reduced lung function as a result of the incident.

Investigation after the incident determined that the release was the result of an unexpected chemical reaction during a production run of a sulphur-based fertilizer blend. The combination of un-decontinued overleaf...

The Government of Canada has taken a major step to protect and conserve Canada's north by announcing the withdrawal of over 10 million hectares of land, near the East Arm of Great Slave Lake, and around the Ramparts River and Wetlands, both in the Northwest Territories. This is one of the largest land conservation initiatives in Canadian history.

The interim land withdrawals are a major step forward towards creating a national park in the East Arm of Great Slave Lake and a national wildlife area for the Ramparts River and Wetlands (Ts'ude niline Tu'eyeta). The Government also announced an Interim Land Withdrawal to protect approximately 62,000 square kilometres with the Akaitcho Dene First Nations from the allowance

of mineral staking, sale or lease during the course of negotiations.

The Government will also be providing $3 million for a study to assess the feasibility of establishing a national park in the vicinity of the East Arm of Great Slave Lake and $830,000 over five years to establish the Ramparts River and Wetlands National Wildlife Area.

Feds make additional commitments for Lake Winnipeg clean-up The Government of Canada will be investing $18 million under the Action Plan for Clean Water to fix serious water quality problems affecting Lake Winnipeg. This is an additional $11 million to the $7 million already committed.

Increased funding for the clean-up of the Lake Winnipeg Basin will support a science-based approach to understanding how nutrient runoff affects the ecology of the lake and how to control nutrient contributions in watersheds. The Government will also expand and improve the network of water monitoring sites in the basin area. Through these measures the Government hopes to reduce bluegreen algae levels, restore the ecological integrity of the lake, ensure a sustainable fishery, and reduce beach closures.

Ontario acts to protect Lake Simcoe from high phosphorus loads The Ontario government wants to develop long-term measures that will protect the health of Lake Simcoe.

Immediate actions include proposed interim limits on municipal and industrial sewage discharges and stronger requirements for stormwater facilities. An $850,000 investment will support information sharing and research into reduced phosphorus discharges from other urban and agricultural sources. This investment will also help to promote awareness of what people can do around their homes and workplaces to reduce their phosphorus footprint.

Over the long term, the province will work with the community and stakeholders to develop legislation to improve sewage treatment standards and set strict continued overleaf...

MB to cut phosphorus levels in dishwasher detergents Legislation recently introduced will virtually eliminate the phosphorus content in all household automatic dishwasher detergents sold in Manitoba. This is a key step in a package of water-protection measures designed to stem the flow of excess nutrients into provincial water-

The minister said reducing phosphorus from household automatic dishwasher detergent is a key step in a continuum of action to reduce the flow of excess nutrients from urban and rural residential areas. The province is taking the following actions : • Introduce legislative phosphorus restrictions on household automatic dishwasher detergents; • Introduce regulatory changes to limit application of cosmetic lawn and garden fertilizers containing phosphorus in residential areas; and • Outline new Manitoba Conservation measures to address the use of septic fields in urban areas as well as in provincial parks.

Mitsubishi ozone systems now designed for wastewater applications

Mitsubishi’s ozone generators feature patented technology said to maximize efficiency and continuity of operation.

Increasingly, municipalities and industries must treat wastewater to higher standards, as regulations grow tougher, and the need for re-use increases. Mitsubishi Electric Power Products has provided ozone systems for drinking water plants in North America. The company now provides ozone systems for wastewater applications, including disinfec-

tion, color removal, odor control, and oxidation of compounds of emerging concern (CECs).

Robert P. Kim, of Mitsubishi Ozone Systems says that “the systems required for some flow rates may be large in order to provide ozone in the concentrations required. We are the only US based manufacturer of large systems.

“Ozone systems are primarily electronic, and what makes ozone work or not work for regulated water applications is reliability for continuous delivery and optimized operating efficiency. To get that reliability and cost control, WWTP operators need particularly good performance from ozone manufacturing cells, power supplies and input air drying equipment.”

A reliable ozone system can eliminate the need for chlorine, the need to neutralize it and to control regulated chlorine by-products, pathogenic microorganisms and compounds of emerging concern.

“Ozone doesn’t leave a residual because it is a very unstable molecule that reverts back to oxygen after it has done its job,” Mr. Kim explains. “It can also oxidize toxic organic compounds that fil-

ters cannot remove, such as endocrine disrupting compounds (EDCs), which are becoming of increasing concern.”

NEWS Delivery included a pumping station with six RDLO 700-980 pump sets and various valves, surge vessels and matching control systems. Each of the pumps is designed for a discharge head of 60 metres and is driven by a 1.350 kW three-phase motor. With all five main units running at the same time, the plant reaches a flow rate of more than 7,000 litres per second.

The pumping station is located in the Algerian part of the Atlas mountains, in a place called Taksebt. An artificial lake of the same name stores about 100 million cubic metres of water, which is treated in the pumping station and then transported to the coastal area via two 100 kilometer long pipelines.

Fly to fight invasive species in Everglades To an untrained eye it might be mistaken for an average housefly, but Lixadmontia franki has a greater purpose. This species of fly is the latest weapon in a bi-

ological battle to control an invasive species of weevil threatening native plants in Florida’s Everglades and beyond.

The South Florida Water Management District, in partnership with the University of Florida Institute of Food and Agricultural Sciences, has released dozens of these tiny flies as part of an ongoing study to determine their effectiveness in controlling the Mexican bromeliad weevil, Metamasius callizona.

Introduced species control is a key component of the District’s environmental restoration mission, including the Comprehensive Everglades Restoration Plan (CERP). The District invested $442,000 in 2007 on continuing efforts to reclaim Florida’s native habitat from hostile invasive plant and insect species, including $17,000 on the fly research. Altogether, Florida has invested close to $2 billion toward CERP projects designed to restore, protect and preserve the water resources of central and southern Florida, with a primary focus on reviving the nation’s unique Everglades ecosystem.

Invasive species such as melaleuca,

old world climbing fern and Australian pine, as well as the Mexican bromeliad weevil, can dramatically change Florida’s habitat. In moving to Florida, these species left behind natural predators that kept them in check in their native habitat.

Scientists look for natural control methods in the species’ home ranges to identify ways for controlling them.

UMA Engineering Ltd. received four industry awards at the 2007 Consulting Engineers of Saskatchewan (CES) Awards of Excellence gala, held recently in Saskatoon.

The Marquis Industrial Trunk Sewer Project in Saskatoon was recognized with two Awards of Excellence, one in the Infrastructure category, the other in the Project Partnering category. In addition, this project also won an Award of Merit in the Building Science category.

UMA Engineering acted as consulting engineer to Hamm Construction Ltd. for the development and preparation of an engineered excavation and tunnel

plans for the sewer project, which is one of the largest single underground infrastructure contracts undertaken by the City of Saskatoon. The work involved installing 1200-mm to 3050-mm diameter concrete pipes to a depth of 7.5 m to 12 m, as well as a pipe crossing at the CNR Warman Subdivision. Other key elements of the project included risk assessment and construction of an 800 m long by-pass track. Sub-consultants included HK Mittal and Associates.

Rounding out UMA’s award-winning projects at this year’s gala was an Award of Merit in the Environmental category for the Cigar Lake Permanent Access Road Project. www.uma.aecom.com

Dechlorination Control that actually works!

ATI’s new Series A15/66 Residual Sulfite Monitor is the perfect answer to process monitoring and control.

Since even a small sulfite residual indicates complete chlorine removal, continuous measurement and control of excess sulfite results in significant savings in chemical costs while assuring a zero chlorine discharge.

Residual Sulfite is measured using a unique vapour phase analytical system. Sulfite in the sample is transferred to the vapour space above a reactor system where the measurement is made.

The result is that the sensor never comes in contact with the sample.

NEWS cluding those that would improve navigation, repair hurricane damage, restore wetlands and prevent flooding. In response, America's seaports and related port industries, which are challenged with handling unprecedented cargo volume growth and demands from increasingly larger ships, will mount a "full-court press" on Congress to lock-in the first veto override of the Bush Administration.

"This bill is as much about ensuring jobs and income growth for the nation as it is about water projects," said Kurt Nagle, American Association of Port Authorities (AAPA) president and CEO. "America's seaports have been the backbone of trade growth and economic prosperity since the country was founded.

The port industry has invested billions in new infrastructure to accommodate increasing trade volumes. Yet, there haven't been any new federal navigation improvement projects authorized in a Water Resources Development Act since 2000."

Mr. Nagle emphasized that by overriding the President's veto, Congress can proactively address the seven-year backlog of water infrastructure projects and policy changes "that are sorely needed to keep our marine highways and trade gateways open and functioning."

Two thermal oxidation projects awarded

ing the 800 HP motor that would otherwise be needed.

Degremont Technologies–Infilco was recently awarded two multimillion dollar contracts for the design and installation of Thermylis™ HTFB (high temperature fluid bed) systems.

In Pickering, Ontario, the Duffin Creek WWTP will handle 210 metric tonnes per day of sludge with two treatment lines. The City of Cincinnati, Ohio, has ordered three thermal oxidation lines to treat 238 metric tonnes per day of sludge at their Mill Creek WWTP. The two contracts have a combined value of over US$80 million.

In the thermal oxidation process, sludge is directly fed into a very hot fluidized sand bed where water is evaporated and organic materials are combusted, using high temperature to reduce the dewatered sludge by 93% to a much smaller quantity of inert ash (as low as 7%). The process is said to be highly efficient, odour free and can generate useful heat for the production of process steam or electricity.

Superheated steam generated at Duffin Creek will be used in a turbine to drive the fluidization air blower, replac-

ADI Systems treats ethanol plant’s thin stillage ADI Systems has developed a wastewater treatment system that treats thin stillage from Renova PLC’s first ethanol plant in North America. In addition to reducing the effluent organic load from the plant, energy costs will be reduced significantly, which will directly lead to a material bottom-line volatility reduction for Renova. Biogas recovered from the system will be used to generate steam and electricity, improving the overall energy balance of the operation by completely offsetting the use of fossil fuels.

Nutrient recovery capability is also incorporated in the process for a potential source of by-product revenue.

The ADI treatment system at the Renova plant is designed to treat all of the plant’s thin stillage and will also treat other available biomass from neighboring operations in the area.

Ultrafiltration membranes selected for Peel Region GE's membrane technology has been selected for a 380 ML/d retrofit and expansion of the Lorne Park Water Treatment Plant, Region of Peel, Ontario. Once completed, the Lorne Park WTP, which is built largely beneath a community park on the shore of Lake Ontario, will be the world's largest municipal water treatment plant to use ZeeWeed ultrafiltration membranes. The membranes will replace the original granular media filters installed when the plant was constructed in 1975. The expansion will increase the facility's water treatment capacity by 45% with minimal impact on the waterfront recreational area located above the underground facility. Existing settling tanks will be retrofitted to accommodate the membrane cassettes and a 16,000 ft2 (1,500m2) extension to an existing building will house the permeate pumps and other ancillary equipment. www.ge.com/water

Biosolids

Why biosolids applications make sense

By Phil Sidhwa

here have been several media reports giving negative viewpoints on biosolids and these present misleading and confusing information. Much rhetoric has been directed at municipal and provincial governments as well as the private sector’s approach to Ontario’s biosolids land application programs. Some criticism lacked scientific studies or other findings relating to any potentially deleterious environmental and health impacts of biosolids. It is now time that biosolids’ programs be considered within a more rational context.

There is plenty of evidence out there but often the evidence just doesn’t say what opponents to biosolids would like.

We should all be willing to debate the issues with greater principle and discipline. The dire doomsday warnings of some activists should be kept within the context of all professional studies and history. Misguiding the public by warping scientific principles and misinterpreting available data serves no one but a few minorities.

Biosolids are an important source of nitrogen, phosphorus and organic matter to farmers in Ontario. In a cash-strapped agricultural economy, farmers get a valuable no cost fertilizer equivalent, worth about $250/hectare. Moreover, municipalities can recycle biosolids in an environmentally sustainable and economically sensible way for the benefit of society.

In general, this can be done by placing important carbon and organic materials back into the soil, instead of incinerating or landfilling them. Ontario farmers annually receive over $7 million worth of equivalent fertilizer value through these practices. Moreover, this practice reduces the amount of phosphorus extracted from our natural environment. It also reduces vast amounts of

fuel required to manufacture nitrogen in commercial fertilizers.

Ontario has some of the strictest and safest guidelines for biosolids management in the world. These guidelines impose limits on heavy metal content, soil conditions, topographical and hydrogeological factors, separation distances to wells and water courses, waiting periods, timing of applications, volumes applied and record keeping. Municipalities enforce strict sewer use by-laws on industry to limit discharges of metals. This has resulted in a notable decrease in metals entering our sewer systems over the past 25 years. Current practices ensure that biosolids application matches farm cropping and nutrient management plans.

There has been an overwhelming wealth of scientific studies conducted in North America and Europe that prove the benefit and safety of properly applied biosolids to soils, crops, human health and the environment. The safety of this program has been verified through many decades of experience and research by influential scientific bodies consisting of world-renowned soil and water scientists at the United States National Research Council, the U.S. National Academy of Sciences, Environment Canada, the University of Guelph and other academic institutions, the Ontario Ministries of Environment, Health and Agriculture, Food and Rural

Affairs and various other government institutions worldwide.

Over the past 30 years, vigorous testing has been conducted on heavy metals and organic compounds in biosolids, soils and crops receiving this material.

The conclusion from this extensive research, scientific evidence, expert peer review and experience, strongly demonstrates that properly applied biosolids pose negligible risk to consumers, crop production and the environment. In fact, over the past 30 years of experience in Ontario, there has never been a case where properly applied biosolids have caused a negative adverse effect on the health of humans, animals, crops or the environment.

A three-year epidemiological study, conducted by Ohio State University, concluded that their general health, which included respiratory illness, digestive illness, and bacterial and viral infection levels, was the same for people living on farms that used biosolids and those living on farms that did not use biosolids as fertilizer.

The University of Arizona collected more than 500 bioaerosol samples from 10 different biosolids application sites across the US to evaluate occupational and community risks from bioaerosols.

The samples were measured for a number of bacteria, viruses and endotoxins.

The study concluded that occupational

Biosolids and community exposure to viruses and bacteria is very low during and after land application of biosolids. Endotoxin concentrations observed during land application were similar to those observed from tractor operations without biosolids application, implying that the endotoxins are from the soil.

Extensive research conducted by the Ontario Ministry of Agriculture Food and Rural Affairs and others found that, even after several biosolids applications (allowed once every five years) over a prolonged period of time, there was no significant difference in metals and dioxin/furan concentrations in the soil.

Over the past 30 years, millions of tonnes of biosolid materials have been spread on hundreds of thousands of acres of agricultural land. There are over 100,000 environmental professionals who work at treatment plants and land application companies, individuals who are in daily contact with this material. Still today, we have yet to find a single instance in which a valid and

it is evident that such a contamination situation is very unlikely. In fact, the MOE document titled “Operational Guidance for Obtaining Environmental Protection Act Section 46 Approval for the Use of Lands Previously Used for Disposal of Wastes”, clearly states in section 2.3 (h), that Section 46, which puts restrictions on lands used as waste disposal sites, does not apply to Organic Soil Conditioning Sites. This is well-established and has been in place for a long time, and is consistent with the province’s long-standing commitment to beneficial re-use and recycling, to reduce the amount of materials being landfilled.

We must, of course, dedicate financial and academic resources and perform on-going research to address contaminants such as pharmaceuticals and other compounds. We need to bring industries that discharge these materials on board so as to be part of the solution. This approach was successfully used with the blue box years ago. A coordinated strat-

Biosolids are an important source of nitrogen, phosphorus and organic matter to farmers in Ontario. substantiated determination has been made as to the negative effects of biosolids on land or health when properly applied. Hardly conclusive. But certainly compelling support.

Over the past decades, we have no records of any biosolid applications devaluing land in Ontario. This is unlikely to ever happen. To scare farmers from using the material by associating a water or food contamination problem with difficulty in financing is speculative and incorrect. In working with developers who build communities on these lands, there has never been a case of a development application being turned down as a result of biosolids application. In fact, a Phase 1 audit would not show any substantial increase in levels of contaminants, even after several applications.

Governments at the municipal and provincial level stand firmly behind their programs, and with all the regulations, checks and balances, monitoring programs and experience over the years, www.esemag.com

egy with pro-active public education and information dissemination involving all stakeholders is needed to ensure all aspects of the program are addressed and dealt with properly.

Considering the acceptance of recycling by society, the rejection of landfills and the overwhelming evidence of global climate change, the arguments raised against the land application of biosolids that have met strict quality standards are not realistic.

It is up to all of us to be prudent on what choices we make to better our environment and keep risks to a minimum as good stewards of our land. Application of treated biosolids, following Ontario’s guidelines, provides beneficial nutrients, is a safe process and makes a whole lot of sense.

Wastewater Treatment

Solar power does the job for a lot less money!

By Martine Pawlowski

ith the energy and maintenance costs of aerators continuing to climb, managers of municipal and industrial wastewater treatment plants are finding alternative technologies to do the job for less money.

Solar power, combined with a breakthrough in long-distance laminar flow pumping, has made it a highly practical matter for treatment plants to offload at least part of their aeration function to a low energy and maintenance cost solution provided by SolarBee circulators.

SolarBee’s hydraulic technology conserves dissolved oxygen by mixing and distributing super-saturated surface water throughout the pond. The circulation and thorough pond mixing, provided by the SolarBee, with its long-distance high flow, provides effective aeration and the reduction of BOD, TSS and ammonia, while solving odor problems and reducing sludge build-up.

Case Histories Drayton Valley, Alberta Located 130 km south west of Edmonton, Drayton Valley is a fast-growing community of almost 7,000. Their wastewater treatment plant was using 240 to 320 hp centrifugal blowers in the system's wastewater lagoons. High energy and maintenance costs were a major problem. Also, the plant suffered from low dissolved oxygen (DO), sludge build up and short-circuiting and high fecal coliform counts. In addition, they faced difficulties in meeting Alberta Environment

standard effluent limits. Seeking an environmentally-friendly way to lower operating and maintenance costs, and to solve the problems in their wastewater lagoons, Drayton Valley turned to SolarBee water circulators.

Five SB10000 units were installed.

No infrastructure changes were required and the units run 24/7 on solar power and occasionally, with AC power assistance.

The system realized an immediate 30% reduction in kWh, and electricity consumption continues to decrease. Just as important, Drayton Valley has achieved these results: • Average BOD removal has increased from 88.1% to 95.4%.

• Fecal coliform counts are consistently below the limits.

• Chlorine dosage has been reduced by an average of 68%.

• DO levels are increased and sludge digestion has improved markedly.

• The system lifespan is increased and working at 50% over its design capacity.

• Greenhouse gas emissions are reduced.

Rochester, New York Electricity, primarily to power a number of 125 hp mechanical aerators in two wastewater lagoons, was costing a small fortune for the Rochester wastewater treatment plant. Even worse, those aging aerators would soon need a major upgrade, at a cost of about $1.5 million. The plant's Chief Operator, David Green, was determined to implement a better solu-

tion. In all, five SolarBee SB10000 units were installed in the plant's lagoons, and they were used instead of the aerators, achieving the same levels of odor-free compliance for TSS, ammonia and BOD as the aerators. Rochester achieved energy savings of more than $10,000 a month.

Red Bluff, California At Pactiv Corporation, in Red Bluff, California, two SolarBee circulators not only alleviate the cost of energy and maintenance at its aeration basin, but have worked so effectively that the plant’s electric-powered, mechanical aerators have become the back-up units.

Pactiv installed two SolarBee SB2500 units in a secondary aeration basin, where three 30 hp aerators and one 10 hp ejector aerator used to do the job.

Of utmost importance, SolarBee's efforts are helping Pactiv to meet all discharge requirements, limiting both BOD and TSS to 30 mg/L. Aside from their effectiveness in aeration, the SolarBee circulators are also being used more where noxious odors and potentially hazardous aerosol are a concern. The circulation occurs with a near laminar long-distance flow pattern that provides an oxygenated odor cap across the entire surface, thereby keeping a lid on odors and aerosols.

Eco Systems

Fish screen to protect aquatic organisms ish and aquatic plants are an integral part of lakes and rivers.

They are an essential component of keeping natural systems balanced. On many occasions, the water of lakes, rivers, or oceans has to be pumped out to respond to an emergency or to complete a project.

ITT has designed Fish Screens for use with its submersible FLYGT pumps and its group of self-priming pumps to prevent fish and aquatic plants from being sucked into the intake pipes of these pumps when they are installed in lakes, rivers, or other natural bodies of water.

These consist of a rigid structure of

F

galvanized metal to which fine, movable screens of stainless steel are attached.

They substantially reduce the impact of pumps on the environment because they protect most aquatic organisms by preventing fish and plants from coming into contact with the pump or the intake pipe.

In addition, the screens were designed based on the guidelines issued

by Fisheries and Oceans Canada to satisfy the requirements for screens for the protection of aquatic organisms set forth in Section 30 of the Fisheries Act. Two models are available to accommodate flow rates ranging from 0 to 300

Rainwater recovery at UQÀM – a promising application !

Rainwater is collected from roof surfaces.

he Biological Sciences building at the Université du Québec á Montréal (UQÀM ) recently received the prestigious LEEDNC Silver USGBC certification (Leadership in Energy and Environmental Design) with a total of 34 points. It is the second sustainable university building in the province of Québec, after the Lassonde Pavilions of the École Polytechnique de Montréal, which obtained the first LEED-NC Gold institutional certificate in 2006.

The project was designed by Tétrault, Parent & Languedoc Architects. The mechanical and electrical engineering was performed by Teknika-HBA/Bouthillette Parizeau Consortium.

UQÀM has succeeded in implementing a large number of the criteria defined in the LEED grid: site access to public transport; bicycle parking; car pooling and hybrid car facilities, showers reserved for cyclists; thermal performance of the exterior envelope; use of ecological cleaning products, etc.

Rainwater recovery In order to obtain LEED-NC certification and taking budgetary restrictions into account, UQÀM integrated an innovative design to save drinking water. Particular attention has been paid to the management of rainwater, which is recovered and used to supply grey water for toilets and landscaping. Following the green trend, the low-consumption toilets only use six litres per flush (1.6 gpf) compared to the old standard systems which use nine lpf (2.4 gpf). This results in a

water saving of 33%. Waterless urinals also give an additional saving of 380,000 litres (100,0000 gallons) of water per year. The septic systems are used by around 900 people.

The rainwater comes from roof surfaces and neighbouring alleys. The water is collected and accumulated in an underground reservoir with a capacity of 15,000 gallons (56,700 litres) and undergoes chlorination. The water is then filtered with two Vortisand AWT1-30-SI (2-micron) filters, each with a capacity of 100 gpm (22.7 m3/h).

The Biological Sciences building’s installation gives a substantial water saving with a drinking water reduction of 59.5%, of which 11% is related to rainwater polishing. The combined innovative technologies have resulted in a 92% overall reduction in wastewater, with less water to be treated upstream at the filtration plant and downstream at the sewage treatment plant.

Filtration of cooling water Two other Vortisand systems are used to filter the water from the cooling systems, as the building has two independent water cooling systems. The first, comprising two 800-ton cells (totalling 1,600 tons), provides air conditioning in the summertime. One Vortisand AWT2 24 SP filter, with a bypass capacity of 150 gpm (34.1 m3/h) , ensures the optimal removal of particles in suspension. The second 200 ton cooling tower system, is smaller and provides air conditioning during the winter period. A Vortisand filter model AWT1-16-SP with a capacity of 30 gpm (6.8 m3/h) keeps it clean.

The advantages of very fine filtration of cooling system water are the optimisation of heat exchange and reduction in the use of more powerful chemicals due to the absence of particles in suspension.

Ghana’s first international conference on environmental research, technology and policy he West African nation of Ghana has had some difficult times in its history. While it is a nation steeped in valuable natural resources, those attributes were often lost to poor or non-existent environmental management combined with political instability and economic hardships following its independence from Britain in the early 1950s.

But today’s stable government, improving economic development and a native son with a passion, mission and expertise for change, made major strides this summer for a lasting, positive impact on the nation’s fragile environment.

Canada and London, Ontario, took centre stage as the world gathered at an international forum in Accra, Ghana, to identify innovative ideas and solutions for progress.

The Chair, Department of Civil and Environmental Engineering at the University of Western Ontario, Professor

T

Ernest K. Yanful, who was born in Ghana, was the creative and driving force for the First International Conference on Environmental Research, Technology and Policy, ERTEP 2007, in Ghana.

He worked with a team from The University of Western Ontario and the General Manager of Environmental and Engineering Services for the City of London, Peter Steblin. With funding and sponsorship from the Canadian International Development Agency (CIDA), The University of Western Ontario, several private sector and government organizations and the key Ministry of Rural Development, Local Government and Environment of Ghana, the conference had a solid base from which to launch its mission.

ERTEP 2007 attracted some 250 delegates from around the world.

Professor Yanful set a stiff agenda.

“Environmental research, technology applications and policy implementation

have been demonstrated to improve environmental sustainability and protection in several developed economies.

There is optimism that similar gains can be achieved in developing economies and economies in transition. This conference offers an opportunity to discuss grass roots environmental issues, assess efforts by government, and identify what communities and corporate entities can do as a social responsibility to mainstream and maintain environmental protection and integrity for sustainable development,” he said.

It was gratifying to see that what started as a small dream after an international conference on environment in Sweden in July 2005 became a reality on the ground in Accra exactly two years later. The involvement of several key politicians and Cabinet ministers of Ghana as keynote speakers at the conference was a testament to the fact the issues at stake were not trivial.

Foreign Affairs Independence Monument in Accra, Ghana, where the conference was held.

Peter Steblin presented an extensive outline of solid waste management issues from not only a Canadian but also a European and third world perspective.

Mr. Steblin had gained great insight into third world challenges as part of a team that toured Sri Lanka following the devastating tsunami.

“The third world needs practical hands-on solutions to basic problems,” said Steblin. “Experts from first world nations have a habit of leaving behind

Economic Indicators for Ghana Major Exports - gold, timber, bauxite, aluminum, cocoa Domestic Economy - agriculture 36% of GDP/60% of workforce Gross National Income - $6.6B Labor Force - 10 million Unemployment Rate - 20%

lengthy reports and plans that have no practical application in the third world.

It’s tough to talk about curbside recycling when many of the communities don’t have proper handling of unhealthy roadside garbage, proper roads, or even a repair facility for the equipment. That is why it is imperative that we give workable solutions to international challenges.

It’s hard to do that if you haven’t experienced it firsthand.”

One of the lasting and greatest impacts

of ERTEP 2007 may be that 15 students from the Civil Engineering and International Development program at The University of Western Ontario who complete an overseas internship component of their study will receive credits towards their degree. The students will be expected to get their hands dirty with travel and activity in a developing country.

The major accomplishments from the conference did not stop there. Over the next three years, environmental and technology experts from several nations will work to produce a position paper on environmental strategies for research and policy development. Again, that directly impacts nations that may not have the resources or ability to combine fiscal and responsible economic development while protecting the environment.

The Waterra Inertial Pumping System is the most widely used pump for monitoring wells in Canada. For developing, purging and sampling — nothing else comes close. our most popular — The Standard Flow System is best suited for 2” wells and can provide lifts up to 150 feet.This system can be used in wells of varying diameters and a variety of sampling environments.

deep well sampling — The High Flow System is designed to be used in 2” wells or larger where a high pumping rate is desired.This system is also an excellent well development tool in 2” piezometers. piezometer sampling — The Low Flow System is designed to be used in small diameter piezometers (usually 1" ID to 0.75" ID).This system is also useful for sampling in damaged or obstructed monitoring wells. micro wells — The Micro Flow System is popular for use in direct push technology micro well installations.

Power plant in China taps the sea using ultrafiltration

The TARGA-10 cartridges employ a proprietary polysulfone hollow fiber membrane.

o produce electricity, power plants require large volumes of high quality water for boiler make-up and for cooling. However, in most locations in China, no surplus water is available and the government will not allow power plants to place additional demands on already scarce water supplies. To gain government approval, new power plants must either find alternative sources of water like seawater and wastewater or they must pay very high fees for surface water or groundwater.

At the new electrical power plant in the Liaoning Province coastal city of Zhuanghe, seawater was a natural choice. The plant supports the region’s thriving economy, which is driven in large part by the governing sub-provincial city of Dalian, a prosperous industrial center with the third largest port in China and the country’s northernmost ice-free seaport.

The construction of the Zhuanghe plant has been divided into two phases.

The first phase, completed in the fall of 2006, provides 1200 megawatts. When the second phase is complete at the end of 2007, the total capacity will expand to 3200 megawatts. During the first phase, the plant will draw surface water from a reservoir located 19 kilometers away.

Once the second phase is completed, the plant will switch over to seawater for all cooling water and boiler makeup needs.

Ultrafiltration makes reverse osmosis economical The Zhuanghe plant has been designed as a model facility to showcase the best available technology. The first large saltwater desalination plant in China was commissioned in 1999, and it has since been well-established that reverse osmosis has lower operating costs and a smaller footprint than thermal distillation.

The reverse osmosis system at the Zhuanghe plant also has the advantage of being a two-stage process that can be tailored to meet different requirements for particular applications. Only the first stage, seawater reverse osmosis (SWRO), is required for the cooling water used by accessory equipment.

Boiler makeup requires higher quality water that must also pass through the second stage, a brackish water reverse osmosis (BWRO) system.

To optimize the performance of RO systems, and to protect them from fouling, an effective pretreatment system is required. The Zhuanghe plant chose ultrafiltration (UF) as the pretreatment solution because UF occupies a small footprint and provides higher permeate quality as compared to conventional pre-

treatment systems. Fully automatic control and relatively low investment costs were also important factors in the selection of UF technology.

Two trains of UF were commissioned in October 2006, and three additional trains were due to be commissioned by the end of 2007 for the second phase of the plant’s construction. The trains operate in parallel, and are each equipped with 44 TARGA®-10 cartridges having a total capacity of 232 m3/h per train.

Prior to the UF, the seawater is pretreated with coagulation and sedimentation, both performed in the same tank.

FeCl3 or Poly FeSO4 is used as coagulant, and, if needed, anionic polyacrylamide is used as coagulant aid. To control biological growth, sodium hypochlorite is added to the feed of the sedimentation tank. The controlled free chlorine before the UF is about 0.3 to 1.0 mg/l. A 100 µm screen web pre-filter, that can be automatically backwashed, is installed before the ultrafiltration to remove the large particles.

Monitoring

Monitoring groundwater without boundaries n September 2006, management at the City of Guelph’s Waterworks Department moved one step closer toward solving a long-running monitoring efficiency problem in its 51,229 cubic metre groundwater reservoir. The successful completion of a pilot project covering 19 functioning wells scattered around 12 facilities and extended over 150 km2 of land, has resulted in an increase in groundwater monitoring efficiency of up to 70%. Using Diver-NETZ for the study, the integrated monitoring network involved field instrumentation, advanced wireless communication, and data management capabilities.

Guelph’s water comes from a permeable zone within the Amabel Formation.

In places, the bedrock is overlain by overburden deposits – clays, silts and sands that were deposited by glaciers. Some of these layers are aquitards where groundwater movement is extremely slow. The aquitards act as barriers to protect the deeper groundwater aquifers.

I

The Diver-NETZ wireless network decreased data collection efforts from 160 to 16 h/mth.

The City conducted the pilot study in its biggest aquifer, the Arkell Spring Grounds. Located in the township of Puslinch, the Arkell Spring aquifer supplies the City with up to 60 percent of the drinking water.

Challenges Consisting of a Water Level Meter (WLM) tape and numerous man-hours, the traditional method for collecting data involved a series of manual tasks such as traveling to proximity, locating wells, opening and unlocking caps, lowering WLM, and taking readings from each nested well.

Technicians spent over 160 hours collecting groundwater data from 23 wells when measuring conditions such as groundwater level, temperature, conductivity, and barometric pressure. From lock-to-lock, 300 data points incurred a total cost of $33,600 per year on groundwater data collection ($9.33 per data point, $2,800 per month). Factoring in all other costs such as managing and visual-

Monitoring izing data, and producing monitoring reports, the City was limited to a small number of readings per month, thus jeopardizing legislation compliance efforts.

Additional intrinsic costs incurred by the City before the adoption of DiverNETZ included the hiring of qualified personnel, extensive personnel training, and expenses related to vehicle maintenance and operation.

Solution The City of Guelph introduced the Diver-NETZ system in two phases. The first phase involved the use of Diver dataloggers (Diver-Suite), Diver Data Cables (DDC) and Diver-Pocket software. This program allowed for a substantial increase in accuracy and provided hourly data. In addition, the readings were collected from all wells simultaneously, providing an accurate and complete snapshot of the monitoring system.

The second phase was the incorporation of the wireless and in-office solutions (Diver-DXT, Diver-DXD, and Diver-Office). With a wireless connection range of up to 150 metres, technicians were able to locate and collect data

www.esemag.com

from roads and pathways without having to walk directly to wells. In turn, the twoman, 75-hour collection excursion was decreased to a one-person, four-hour walk and drive.

Training on wireless data collection was also provided for technicians and assistants. A four-hour training session was implemented to educate city workers on how to program, collect, and download information for visualizing and reporting.

Results Quantitative results are summarized as follows: • Tenfold reduction in man-hours for collection of 300 data points (from 160 to 16 hours).

• Dramatic decrease in cost per data point collected (from $9.33 to $0.25 per data point).

• Decrease in monthly cost of data collection (from $2,800 to $75, annual reduction from $33,600 to $900).

• Increase in data collected monthly (from 300 to 3,000 data points, 750 readings).

While there was a substantial decrease in training hours and level of ex-

pertise required for collecting data, technicians were also able to avoid site obstacles and hazards including fenced private property, inclines, and rivers.

The funds allocated to the DiverNETZ groundwater monitoring network were instrumental in meeting the City’s legislation compliance efforts while staying within budgetary constraints.

Drinking Water

Packaged technology brings municipal water system into compliance with Ontario regulations

By Richard Ross he Town of Latchford, Ontario, had an aging water treatment system in desperate need of upgrades and improvements to meet the Ministry of Environment (MOE) regulations. The existing surface water treatment plant struggled to consistently meet filter turbidity goals. Replacement of the existing system, rather than rehabilitation, was deemed most appropriate for a long-term solution.

Faced with the need to improve treatment performance, the town hired Earth Tech, Inc. (Markham, Ontario) to evaluate a number of treatment technologies.

Based on the low flow requirements of 250 m3/day (46 USgpm) for each tank of the system, it was determined that factory-assembled packaged treatment systems would be the most cost-effective solution. In addition, to ensure uninterrupted service, it was decided that redundant treatment equipment and chemical feed systems should be installed at the facility as back up.

In February, 2005, Tri-Mite® packaged water treatment systems, one of the Microfloc® products from Siemens Water Technologies, were selected for the plant. The project included: installing two new package filter plants; modifying the raw water pumping facilities; adding duplex chemical dosing and sodium hypochlorite disinfection with storage and spill containment, as well as installation of raw water quality analyzers to evaluate pH, turbidity and temperature.

The water treatment process consists of two pre-engineered packaged water treat-

Flocculation and solids capture occur in a bed of buoyant clarifier media operated at a nominal upflow rate of 11.2m/hr. The high density polyethylene media has a specific gravity less than 1.0 and is composed of beads roughly 2.5 mm in diameter. A portion of the media beads are rolled and scarified to aid in the solids capture process. The clarified water then enters the filter section where it passes through a mixed media bed con-

sisting of anthracite, sand and garnet at a filtration rate of 5.6 m/hr. Each layer of filter media has a progressively smaller effective size and increasing specific surface area to form an ever-tightening filter bed.

Both the clarifier and filter are periodically cleaned using an air-water flushing system to help remove captured solids. Since the clarifier media is buoyant, the addition of air expands the media downward, opening up the pore space to release solids.

The final selection of treatment technologies was based on meeting effluent turbidity goals as defined in the Drinking Water Systems Regulation (O. Reg. 170/03). This regulation regulates municipal and private water systems that provide water to year-round residential developments and designated facilities that serve vulnerable populations such as children and the elderly.

The two-stage adsorption clarification and mixed media filtration system that was provided not only produced excellent effluent quality, but met the protocol requirements with turbidities less than 0.1 NTU and filter effluent color of less than 5 color units.

The facility was completed in December 2006, with the two painted carbon

Diverse products required to burst different pipe materials needing repair

By Collins Orton he choice of pipe material can be a very volatile subject.

Many utilities are so invested in certain materials that it is almost impossible for them to consider others. While there is a high level of familiarity with the application of high density polyethylene (HDPE) pipe in pipe bursting, there is still considerable interest in other pipe material options, by owners, engineers and contractors.

Various pipe manufacturers are working diligently with pipe bursting equipment developers and manufacturers to find ways to adapt their pipe products to pipe bursting installations. It takes the extensive experience of these parties to find suitable ways to install what is best described as sectional, gasketed pipe in the pipe bursting process.

Pipe bursting overview With the recent introduction of new hydraulically powered static pipe bursting systems, contractors now have the ability to split and replace ductile iron, steel and lined pipes, as well as pipes with ductile iron and steel repairs.

During the static bursting process, specially designed bladed rollers are pulled through an existing line by a hydraulically powered bursting unit. As the bladed rollers are pulled through, they split the host pipe. An expander attached to the rollers forces the fragmented pipe into the surrounding soil while simultaneously pulling in the new pipe.

The bladed roller configuration is an

T

essential part of static bursting for steel and ductile iron pipe materials. The specially designed bladed rollers actually split the host pipe instead of ripping or tearing it. This is a clean process and prevents potential damage to the product pipe.

The old pipe must be fractured or split, the remaining fragments compacted into the surrounding backfill, and the new pipe pulled/pushed in before the temporary annular space, created by the pipe bursting tool, begins to collapse and get a firm grip on the new pipe. Once the soil has a firm grip on the pipe, it is very difficult if not all but impossible to continue to move the column of new pipe forward.

95% of all pipe bursting installations.

This procedure always requires adequate lay-down area.

Fusion welding this type of pipe during the pipe bursting process is very time-consuming and generally not performed in the field. Because of years of field experience a number of ways to connect PE pipe to the pipe bursting tooling have been developed. They are generally all reliable with various advantages to the methods. Both pneumatic and static pipe bursting systems can be used for this type of pipe.

Fusion welded PVC pipe The water and sewer industry are just beginning to see this relatively new type of polyvinyl chloride pipe (PVC). It is

Once the soil has a firm grip on the pipe, it is very difficult if not all but impossible to continue to move the column of new pipe forward.

Product pipe options The industry is very knowledgeable about polyethylene pipe (PE) and pipe bursting installations. Fusion-welded joints help to make this type of pipe into a one-piece pipe section to whatever length is required for a pipe bursting reach. For example, a section to be replaced is 500 feet long; a string of PE pipe will be welded together into a string slightly longer than 500 feet and will be laid down in alignment with the launching pit. This method represents at least

butt fusion-welded, similar to PE, and offers a PVC pipe that is suitable for many pipe bursting applications. Although the pipe is somewhat stiffer, thus requiring longer launching pits. 5:1 ratio (Length to Depth), the fusion procedures for welding this type of pipe must be adhered to very precisely. Experience has shown that the typical scratching on the outside diameter (OD) of the pipe is within the manufacturers’ allowances.

This type of pipe cannot withstand the

Static Step #1 First, Quicklock bursting rods are pushed through the host pipe with the Grundoburst, until they reach the launch pit. A flexible guide rod out front helps navigate the existing line.

heavy hammering action of a pneumatic pipe bursting system. Because the pipe is stiffer than HDPE, for example, it must be installed with a static pipe bursting system so as not to fracture the pipe’s connection to the pipe bursting tooling.

Restrained joint ductile iron pipe This is another new application for a type of pipe that has been on the scene for a very long time. The bell and spigot restrained joint configuration requires that the pipe be pulled backwards (spigot end first). This allows each consecutive bell joint to act like an additional pipe bursting expander. Only a static pipe bursting system should be used for this type of pipe. The pipe is assembled one joint at a time in the launching pit and pulled one joint at a time. The joints are made up quite quickly, usually in just a couple of minutes.

The advantage of this cartridge loading approach is that there is no need for a pipe staging area. The new replacement pipe can be unloaded, as needed, from a truck and, at the end of the day, there is no pipe left on site. This process requires the pipe bursting system to start and stop repeatedly. Each joint is madeup in the launch pit, pulled in and then

the process is stopped while the next section of pipe is lowered into the launch pit and assembled to the previous joint.

Loose polyethylene encasement of the ductile iron pipe is not done, as the wrap will be severely damaged by fragments of old pipes during the installation. A pushing jack may be used to help the column forward during difficult bursting operations.

Restrained joint C-900 PVC pipe C-900 PVC pipe with a restrained joint utilizes a spline and groove assembly that is very strong. This pipe is assembled and pulled much the same as restrained joint ductile iron pipe. Only static pipe bursting systems should be used due to the stiffness of the pipe. The connection of the PVC pipe to the bursting head consists of an adapter using the pipe and a steel pulling head of the same configuration as the pipe joint. A cartridge loading method can be used.

However, this type of pipe appears to be flexible enough to join together before a pipe burst and insert through the launch pit with minimum bending.

Non-restrained joint ductile iron pipe This type of pipe has a very low pro-

file joint and was developed primarily for pipe jacking type installations.

When pipe bursting with non-restrained joint pipe it is normal to place the static bursting system pulling rods through the length of each new pipe section and connect to a backup clamp that essentially helps to push the column of pipe from the backside. This ensures that the non-restrained pipe joints stay in compression, and together. The internal lining of the new pipe must be protected from the rods or cable used to pull the pipe. In many situations, the rods are sheathed inside small diameter plastic pipe. This helps prevent any rubbing damage to the lining.

Vitrified clay pipe (VCP) with jacking type joints This particular pipe product is much the same as other non-restrained pipe types. Because this is a clay pipe, special care will be necessary to keep the column in good alignment. These pipe sections come with a layer of compressive material at the joints to help equalize the jacking pressures against the end of each section. Clay pipe is quite heavy and one would expect to see some sort continued overleaf...

Static Step #3 The entire configuration is pulled back through the host pipe. The bladed cutting wheels split the existing line. The bursting head and expander displace the fragmented host pipe into the surrounding soil while the new HDPE pipe is pulled in simultaneously. www.esemag.com

Trenchless Technology of pushing jack in use along with the static pipe bursting system. This type of pipe is installed using the cartridge loading method.

Welded steel pipe Welded steel is installed by pulling with static pipe bursting systems. The pipe is by definition flexible, so it can be welded together and then pulled in as with PE pipe. The reality is that this pipe is not really that flexible and probably will need to be welded together as each joint goes in.

Conclusion The specified pipe and specific pipe bursting equipment should have a proven history similar to the intended application and service environment, as well as data that reflects third-party testing, to substantiate suitability of the pipe by physical property and chemical resistance claims of the manufacturer.

The pipe bursting equipment system(s) to be used should be proven to be capable of the required pipe replacement.

The structural condition of the existing pipe also needs to be evaluated and point repairs identified. CCTV is a very

useful tool in identifying many pipe defects. Recent CCTV tapes and logs should be included as part of the plans and specifications for projects.

Multiple pipe bursting systems and replacement pipes may be evaluated and subsequently specified. Since all systems are not alike, pipe and pipe bursting system capabilities must be evaluated to determine the proper selection for the project under consideration.

There are other types of restrained joint and non-restrained joint pipe that can be installed with similar methods.

Consulting with well-qualified pipe bursting consultants and knowledgeable equipment manufacturers can help to make these applications possible.

Conservation

City of Prince George goes green he City of Prince George, which has a population of 77,000, has committed itself to reducing total community emissions to 2% below 2002 levels by 2012. It is a project that is estimated to cost $825,000.

An immediate area of concern that prompted the Municipality to engage in energy-reducing projects was a perceived reduction in air quality in Prince George. Large factories and businesses that conformed to outdated environmental legislation were now seen to be emitting excessive quantities of pollutants to the detriment of the local environment. As local concerns mounted, wider global preoccupations with climate change and social responsibility also became more pressing.

According to data gathered by the City, Prince George produced 1.237 million tonnes of GHG (greenhouse gases) in 2002, of which 7,080 tonnes were emitted by the City of Prince George’s operations and facilities. If the City were to continue emitting at this level without

T

www.esemag.com

doing anything, emissions were estimated to grow to 1.352 million tonnes by 2012.

Clearly something needed to be done.

Since taking the decision to reduce energy consumption and emissions, Prince George has embarked on a Community Energy System where water will be heated at a central plant before being supplied to city buildings. Individual boilers will fast become redundant, which will see an immediate decrease in buildings’ energy consumption. Furthermore, the central plant will be fuelled by renewables, such as biomass, which will reduce the level of GHGs and pollutants being emitted.

The City of Prince George is also the first in Canada to pilot an energy-saving streetlight system. The project involves testing light-sensing controls in 170 streetlights. During off peak hours when there are few pedestrians and vehicles around, the streetlights will be dimmed.

The City expects to reduce its energy use and costs by approximately 40% through this system.

Both projects, funded in part by the BC Hydro Power Smart Energy Managers program, will play an important role in helping the City reach the targets it has set for itself. In addition to these two projects Prince George is looking to become a leader in energy efficiency in their own facilities.

As energy management coordinator for the City, Energy Advantage will use its total energy and environmental management approach to find efficiency opportunities and create a sustainable program to reduce energy usage. Solutions can range from building energy awareness and an energy conservation mentality, to retrofitting lights, to developing optimized operational and maintenance procedures or simulating building design. It will also develop plans that allow employees to implement and sustain ongoing energy efficiency practices.

ect, the innovation in its design and construction adds to the impressiveness of this project. Instead of the traditional formwork and falsework, 262 precast Double Ts were lowered into place to form the cover slab, which is supported by cast-in-place walls and columns and precast beams. This shaved almost three months off the construction schedule and contributed to substantial budget savings.

Structural stability is ensured with the 100 mm depth of reinforced structural topping provided on top of the Double Ts, together with a roof membrane which will provide added protection against leaking.

The new reservoir’s hydraulic mixing system consists of a concrete pressure pipe manifold, which runs the length of each cell, complete with mixing valves.

The manifold reduces in size along its length from 1,500 mm to 900 mm diameter to maintain equal flow through the sixteen 600 mm diameter closed-type rubber valves in each cell. This mixing system provides a cost-effective solution to prevent water stratification and also maintain chlorine residuals.

KMK Consultants completed the Class EA and the detailed design, which also includes the installation of new standby power facilities, new transformers and retrofit of the existing electrical system and controls.

The Beckett Sproule Reservoir is in Brampton, Ontario.

Grounding for enhanced system reliability

By Ryan Dutrisac, E.I.T. he existing Capreol water supply system is a municipal system consisting of three separate groundwater wells located in the community of Capreol, 40 minutes north of the Greater City of Sudbury.

Two of the wells, “M” and “J”, are located on a common site, just south of the community, while the third, Well #6 is located in Capreol, near the local ski hill.

The First Engineers Report carried out by Dennis Consultants, a Division of R.V. Anderson Associates Limited, in March of 2001, identified that Well #6 had a number of compliance issues. Due in part to the large cost associated with upgrading the facility, the City decided to abandon the Well and construct a single point water treatment facility located on the site of the remaining two wells.

The site would be comprised of two groundwater wells, chemical disinfection, ultraviolet disinfection (UV) and a water booster station which would take water from the nearby Valley East system as required.

Since the new “combined” water treatment plant would become the only source of potable water for the 3,400 residents of Capreol, the design had to be sufficiently robust to ensure that the site would be kept operational during adverse conditions. For instance, as the new plant was located approximately 1,700 metres from the first customer, a new supply watermain was installed running parallel to the existing one so that redundancy was provided in the case of a watermain break. Moreover, the standby power system, consisting of a diesel generator and automatic transfer switch, was upgraded to handle the increase in load dictated by the installation of the booster station and UV reactors.

Electrical design process The electrical design for the new plant consisted of upgrading the existing hydro service, a new standby generator, a new motor control centre and various other appurtenances. During the pre-design stages, City employees expressed their concern with the various incidents of equipment burning/arcing that had occurred at the site over the past number of

The new water treatment plant and booster station were commissioned in August 2007.

years. Based on past experience, it was believed that these incidents were linked to lightning strikes and voltage spikes/surges at the site.

Standby power, in the form of a 400 kW diesel generator was a key component in the new system design. The generator would provide uninterrupted power to the entire facility during a loss of utility power. However, since this plant would need to be kept operational to maintain water supply to the community of Capreol during all fault conditions, increased levels of protection had to be considered. Lightning arresters were added on the utility supply side to reduce the potential for lightning strikes. Also, for enhanced lightning protection, a rigorous building grounding system was installed to provide adequate bonding for all exposed metal parts on the building.

To reduce the voltage surges which had been observed at the site, a transient voltage surge suppressor (TVSS) unit was installed on the load side of the main breaker. Although a fully functional TVSS is a proven method of reducing voltage spikes and surges, its functionality works at “shunting” the voltages to ground and it does little in limiting fault currents. Consequently, since fault currents are typically diverted to earth through the building’s grounding system, the selection of the grounding technology that was going to be used at the new water treatment plant became crucial.

Grounding fundamentals Grounding of any facility, albeit industrial, commercial or residential, can be divided into two categories: equipment grounding and system grounding.

Equipment grounding is more commonly referred to as “bonding”, which is the physical connection to ground (through rods, plates and/or electrodes) of all non-current carrying metal parts of the wiring system including but not limited to outlet boxes, metal conduit, motor frames, cabinets and metal enclosures.

System grounding typically refers to the connection from one of the current carrying conductors of a distribution system or interior wiring system, or simply the neutral of a wye-connected transformer or generator. When it comes to system grounding, the four most common approaches for industrial facilities are ungrounded, solid grounded, high resistance grounded and low resistance grounded.

Ungrounded systems occur where there is no intentional connection to ground except through measuring devices. This type of grounding is rarely used anymore, due to the large frequency of destructive transients inherent to ungrounded systems. Furthermore, since ungrounded systems do not provide a path for the ground current to flow, they can potentially be harmful to plant personnel working near these faults.

Solid grounded systems are the most common in operation today for 600V

Operations systems, which is the voltage at which the majority of Canadian plants operate.

They occur when the neutral points have been intentionally connected to earth ground with a conductor having no intentional impedance. Although solid grounding offers improvements over those of ungrounded systems, it lacks the current limiting ability of resistance grounding, which can lead to arcing of the high energy dissipated in the fault.

Resistance grounding, which can be divided into high and low resistance grounding, is realized when an intentional resistance (resistor) is connected between the neutral of the source and earth ground. The principle behind resistance grounding is a simple ohm’s law calculation: I =V R Where I = The limit of fault current (Amps) V = System line to neutral voltage (Volts) R = Value of neutral grounding resistor (ohms) This allows the designer to select a resistance to limit the fault current to a predetermined value in order to prevent equipment damage.

According to the IEEE, Standard 142-1991 Recommended Practice for Grounding of Industrial Power Systems, the reasons for limiting ground fault current may be one of the following: • To reduce burning and melting

www.esemag.com

effects in faulted electrical equipment.

• To reduce mechanical stresses in circuits and equipment carrying fault currents.

• To reduce electric shock hazards to personnel caused by stray ground fault currents in the ground return path.

• To reduce the arc blast hazard to personnel who may have accidentally caused or who happen to be in close proximity to the ground fault.

Low resistance grounding limits the ground fault current to a high level (typically 50 amps or more) to enable the operation of fault clearing devices. This method has the added advantage over solid grounding in that it further reduces the ground fault current to prevent equipment damage. This type of system is common to medium and high voltage systems (voltages above 1000V) where equipment protection rather than service continuity is paramount.

High resistance grounding uses a larger resistor to limit the ground fault to a low level, typically 5 amps or less for industrial applications. By limiting the ground fault current, the fault can be tolerated on the system until it can be isolated and removed by qualified personnel. Another major advantage of this method of grounding is the elimination of destructive flashovers (arcing) to ground – mitigating both equipment damage and injury to personnel.

This advantage will become increasingly important with the implementation of equivalent NFPA 70E standards to Arc

Flash Protection in Canada (new standard to be designated CSA Z462 and is currently under development). This standard is concerned with personnel safety and, since high resistance grounding limits electric shock hazards to workers, it may be more cost-effective and practical to install a neutral grounding resistor rather than purchase expensive arc resistant switchgear and protective clothing.

For the Capreol Water Treatment Plant, the method of system grounding for the neutral of the main incoming transformer (wye-connected secondary) was narrowed to either solid grounding or high resistance grounding. Although both methods had unique benefits, high resistance grounding offered superior equipment protection, increased safety and service continuity.

The high resistance grounded system in Capreol, as recognized by Section 101100 of the Ontario Electrical Safety Code, consisted of an I-Gard grounding resistor, an I-Gard ground fault relay and a ground CT. The fault relay is continuously monitoring the level of ground fault on the system. When the fault level exceeds 0.5 amps, an alarm is sent over the City’s SCADA network and an electrician is dispatched to the site to locate and repair the fault. Meanwhile the electrical system will continue to operate without interruption to the supply.

Energy

Co-generation enters its second century

By Ken Wiecke, P.Eng. and Derek McCann, P.Eng. ong ago, before energy shortages and environmental awareness, co-generation was an obscure engineering practice of interest largely to those industries which, like pulp and paper, had access to vast quantities of cheap biomass fuel and a need for process steam and power.

Today, on the eve of its second century, biomass-powered cogeneration is poised to grab a bigger share of Canada’s energy mix, powering a greater number of industrial plants and making its way into home and commercial space heating.

Co-generation, also known as combined heat and power (CHP), has lots going for it. It burns fuel at higher efficiency than conventional single-source thermal generation; in other words, it produces the same amount of electricity and heat with much less fuel than when the two are produced separately. While it can work with natural gas and other fossil fuels, co-generation can also transform clean, renewable, biomass into electricity, process steam, and heat. Some newer pulp and paper plants actually generate surplus electricity that they sell back to the grid, no mean feat in an era of ever-rising power prices.

Biomass energy, also known as bioenergy, is the name for all forms of renewable energy from organic materials such as ani-

Co-generation is at its most efficient when its heat is used on-site or very close to it.

mal manure or municipal residues. For the purposes of co-generation, biomass is usually defined as plant materials produced by photosynthesis. Burning this biomass is carbon dioxide-neutral, that is, the process releases the same quantity of CO2 that the plants absorb during their lifetime. Every time biomass displaces fossil fuel, greenhouse gas emissions drop.

Unlike fossil fuels, which are finite, biomass is an infinitely renewable energy source. Pulp mills located in vast forested areas and near sawmills can get pretty much all the bioenergy they need at prices well below what they would pay for oil, natural gas, or commercially generated power. If they practise responsible reforestation, that inexpensive resource is renewable forever.

The federal government has begun to pay attention, too; in 1976, it introduced tax incentives to encourage the pulp and paper industry to build co-generation facilities. It scaled back those incentives in the budget of 1994 but then offered accelerated capital cost allowances for high-efficiency co-generation plants a decade later.

In the United States, Washington offers tax breaks for construction of cogeneration facilities and guarantees a market for any surplus electricity these facilities generate. Denmark and Finland each get more than one-quarter of their total power from co-generation, with Finland fueling 10 per cent of that prowww.esemag.com

duction with biomass. Finland also makes widespread use of district heating, in which large swaths of residential and commercial buildings are heated by co-generation.

Anyone who’s ever driven a car in winter has already encountered the principle of co-generation: surplus heat generated by the car’s engine, instead of being expelled as exhaust, is recycled to heat the passenger compartment. In effect, one fuel burn generates two benefits: mechanical energy to move the car, and heat to warm the passengers.

In a single-purpose thermal power generation, a coal-fired electric generating station, for example, fuel is burned

to produce electricity. But the process has a maximum efficiency of just 35 per cent; the remainder of the fuel consumed in the process is released as exhaust heat, dissipating into the atmosphere and rivers or oceans to be lost forever. In cogeneration, that exhaust heat is captured to produce steam for process or space heating, achieving efficiencies as high as 70 per cent.

Each co-generation facility is different, depending on the primary demand that it serves. If that primary demand is electricity, then the system is designed and built primarily to produce that, with heat or steam as a secondary benefit.

Pulp and paper mills require great quantities of steam to run their paper-drying process so their early co-generation systems were designed to generate steam, which complemented traditional power generation.

Co-generation is at its most efficient when its heat is used on-site or very close to it. Overall efficiency drops when the heat travels much further, and the transmission system - large, heavily insulated pipes - is more expensive and less efficient than the wires that can transport electricity over far greater distances for the same energy loss.

Canada’s pulp and paper mills have been making use of co-generation since the 1930s, drawn to the higher efficiency of high-pressure boilers used to generate process steam, with electricity as a byproduct. The mills usually use continued overleaf...

Energy two principal sources of biomass fuel: pulpmill and sawmill residues such as sawdust, wood chips and tree bark; and pulping “liquor,” a mixture of water, pulping chemicals, and organic matter produced in the process of transforming wood into pulp. In the case of pulpingliquor fuel, the process has the added advantage of recycling chemicals used in the pulping of wood, creating a closedloop process that keeps these substances out of the environment.

Well over one-half of the Canadian chemical pulp mills’ energy needs are met by co-generation. The industry has about 1,500 megawatts of installed generating capacity fuelled partly by the burning of residues at co-generation facilities inside pulp and paper mills. The additional heat from co-generation is used to produce the steam needed to dry pulp in the process of transforming it into paper, and to heat industrial work areas. Co-generation has also led to greater profitability by allowing mills to ride through any loss of power due to grid outages.

Decades ago, pulp mills would have required power from the grid in addition to the electricity they generate themselves. Newer plants now generate so much power that they have surpluses to sell back to the grid. However, that trend is not growing much in Canada, where electricity from utilities remains reasonably inexpensive and where pulp and paper is a mature industry.

Electric utilities in Québec and British Columbia both have long-term deals to buy power from independent cogenerators, with one such agreement in Québec calling for that province’s utility to buy electricity from a pulp mill with a 20 megawatt generating capacity at about six cents per kilowatt hour. The mill buys its full electricity needs from the utility at between three to four cents.

The six-cent selling price is what the utility deems to be the avoided cost of new, costlier generation.

Elsewhere in the world, these transactions are getting considerably more valuable. As virgin forests are developed, the pulp and paper industry is taking advantage of advances in co-generation to build bigger, more modern plants that make full use of the process’ potential.

One new mill in Chile, for example, generates so much biomass electricity that it is able to meet all of its needs and sell power to the local utility. The mill actually makes more money from electricity

sales than from its core pulp-and-paper business. At times when demand drops, the mill actually shuts down its pulp line but continues to operate, just like a central power station.

Technological advances continue to come at regular intervals. For example, some plants are dealing with the shortrange travel limits of steam by using heat-retaining fluids to transport the heat over greater distances. There are also advances in the efficiency of power-generating turbines designed specifically for the co-generation process, along with ever-increasing pressure capacities of new boilers to further heighten the efficiency of the heat and steam produced through co-generation.

Other creative applications of cogeneration include “eco-industrial networks” in which electricity-producing facilities are built in close proximity to groups of industrial processes using electrical and thermal energy. In this way, outputs and wastes from one plant become inputs at others.

NEWS US company to face prosecution in Canada for cross-border pollution The Superior Court of Justice in Sarnia, Ontario, has issued an order directing a lower court to summon DTE Energy, based in Michigan, to face charges of polluting the St. Clair River with dangerous amounts of mercury.

Last year, Scott Edwards, a Canadian citizen, filed charges alleging that DTE Energy's coal-fired energy complex on the banks of the St. Clair River has been violating Canada's Fisheries Act for two years.

Detroit Edison, a wholly owned subsidiary of DTE, operates the St. Clair/Belle River coal-fired power plant complex in eastern Michigan. Monitoring data show that these facilities emit significant amounts of mercury each year, with more than half landing locally in Canada and the St. Clair watershed.

When the mercury enters the St. Clair River, it spreads throughout the food chain, harmfully altering fish habitat and rendering fish unsafe for human consumption, which is a violation of Canadian fisheries law.

Currently, both the Canadian and US sides of the St. Clair are subject to highly restrictive fish consumption advisories because of elevated levels of mercury.

Native populations along the Canadian side of the river have had their commercial fishing rights stripped away.

Windsor Utilities Commission is prepared for DWQMS

The Ambassador Bridge connects Windsor to Detroit, Michigan

he Ontario Ministry of the Environment’s mandated Drinking Water Quality Management System (DWQMS) was introduced to help prevent another Walkerton catastrophe. Now, every municipal drinking water facility throughout Ontario is subject to becoming “DWQMS accredited” within the next few years. The Windsor Utilities Commission (WUC), under the leadership of John Stuart, Director of Water Production, was one of the first organizations to embrace and begin implementation of the quality program.

T

As part of the panel of drinking water quality experts, Stuart played an integral role in the DWQMS design. In Ontario’s water industry, there has been a lot of apprehension surrounding the new mandate.

In most cases it is simply a function of industry representatives (system owners and operators) not having previous exposure to quality management systems. Many are anticipating that the project will require resources beyond their means or that it may have a disruptive effect on day-to-day operations. To help address these concerns, the Ministry of the Environment re-

leased a DWQMS Guidance document that details the specific requirements and tips to help owners and operators become better informed about their responsibilities and expectations.

When developing and writing the standard, the team of water system experts assigned to creating the DWQMS took aim at making the standard as implementation-friendly as possible.

According to Stuart: “Initially, the standard was going to be more prescriptive; however, the current DWQMS is adaptive.” By rendering it adaptive, irre-

Information Management spective of an organization’s culture, size, complexity and/or existing management systems in place, the DWQMS’ design allows for it to be almost seamlessly incorporated into existing operations without substantial disruption. The standard allows different system types and reporting lines to come together and create a system that makes sense to the individual organization; the system can, therefore, be very complex or more simple to suit the organization.

As part of the DWQMS development team, John Stuart was also asked to provide insight on the importance of the provincial program from a ‘beyond-compliance’ viewpoint. Implementing a quality management system such as DWQMS “broadens our view of what quality entails. It goes beyond the quality of the finished product and includes the quality of the entire process. Moreover, it encourages organizations to implement a multi-barrier approach to quality that includes an examination of the raw water supply, treatment chemicals, equipment and many other facets of the system,” he says.

WUC’s implementation has been a

positive experience and continues to stay on track. The project is approximately half-way to completion. Policies and procedures have been put in place, most risk assessments have been conducted (a DWQMS requirement) and the project has been effectively communicated company-wide. The next steps are providing training and developing the awareness of the requirements.

When asked to detail his critical success factors, Stuart refers to how his team has used a software tool called RRAM™, which was designed to assist water utility organizations with development and implementation of management systems, including DWQMS. It can capture and manage the documentation and training requirements, which are considered two of the most difficult challenges in terms of management and maintenance. “ RRAM allows us to disseminate information to the appropriate individuals within the organization in a timely and efficient way,” says Stuart, adding that the program will reveal additional value once DWQMS accreditation is achieved and the system requires maintenance be-

yond accreditation. Post implementation, ‘lulls’ tend to creep up between audits (each system will be audited by a third party certification body appointed by the Ministry of the Environment). Any organization can lose focus because the main goal (accreditation) has been achieved and continued attention to detail is foregone. Through mechanisms such as prompts to follow-up on corrective actions, the program serves to help prevent these ‘maintenance gaps’ which jeopardize the system’s functionality and value.

The Windsor Utilities Commission can use the technology to bring various management systems together to combine information throughout the organization. For example, using RRAM, WUC is implementing the OHSAS 18001 Health & Safety management system in parallel with the DWQMS project.

Despite the software’s effectiveness, an individual or team dedicated to the management and maintenance of the system is needed in order to avoid these ‘lulls’. Organizations, especially larger and more complex ones, can expect to continued overleaf...

add two to three full-time employees to complete the entire project.

However, even with an effective team in place, there could be potential technical expertise gaps. For example, the strong emphasis on Risk Assessments & Outcomes and Internal Auditing in the DWQMS will likely prove to be stumbling blocks for many organizations, necessitating the hiring of outside

expertise. The Windsor Utilities Commission hired SpringWater QMS to help with the development and implementation of these more challenging areas.

(Recently, Springwater QMS and Genivar formed a strategic partnership, called GENIVAR-SpringWater QMS).

When asked to provide other lessons learned from his experience with DWQMS implementation, Stuart offered

the following advice: • Take advantage of management system experts/consultants as it alleviates much frustration in terms of addressing concerns and challenges.

• A management system is a management system and, therefore, it is not necessary to fully understand the mechanics to implement a process – don’t be discouraged by the unknown.

• All organizations within the industry are concerned with managing information and we believe that we are doing things correctly; we, therefore, need external expertise to help us ensure we don’t overlook anything.

An objective perspective can go a long way in addressing situations before they become major non-conformances.

• Make sure everyone involved in the project understands the general requirements and take advantage of available guidance documents.

How creative thinking led to an innovative solution for treating wastewater in Ontario

By Peter Steblin and Elvio Zaghi inding ways to upgrade aging wastewater treatment facilities is a common challenge for many cities throughout North America. But for the City of London, Ontario, the “same old” way of doing things wasn’t enough. The city is currently constructing the largest membrane bioreactor (MBR) project in Canada for municipal wastewater treatment, which is proving to be an innovative, creative way of solving their capacity needs without breaking the bank.

The city is experiencing strong growth pressure, and city officials had to determine a way to increase wastewater treatment capacity without putting too large a financial burden on its budget. But, after examining the typical alternatives for expanding the wastewater plant, the city knew there had to be a better solution. In turn, the city held a workshop to challenge a group of consultants and brainstorm solutions. The group ultimately determined that an innovative MBR retrofit of the Oxford Pollution Control Plant offered an affordable opportunity to treat increasing wastewater at the tertiary level, at costs comparable to secondary treatment.

Background London’s Oxford Pollution Control Plant (PCP) consists of two parallel treatment sections - an older section (Section 1) rated for 5,450 cubic metres per day, and a newer section (Section 2) rated for 4,540 m3/d for a combined capacity of approximately 10,000 m3/d. The high residential growth within Oxford’s sewershed triggered the urgent need for an additional 9,000 m3/d treatment capacity.

In Spring 2006, the city and its consultant conducted a Class Environmental Assessment (EA) to evaluate the options for expansion. Typical of the EA process, the assessment was a planninglevel initiative centered upon the standard EA framework in which: • The problem statement was defined.

• Various planning alternatives and typical design concepts were evaluated.

From Left: Peter Klein, Stantec, Project Coordinator, Peter Steblin, City of London, General Manager, and Elvio Zaghi, Stantec, Project Manager.

• Public meetings were held.

• The preferred solution was identified.

During the EA process, a number of potential expansion alternatives for the Oxford PCP were considered. Frustrated with the conventional solutions facing them, the city wanted to look beyond the status quo and organized a workshop to augment the EA process, inviting other consultants to help the team find a better, more creative solution.

The workshop approach has been a strategy favoured by the City of London since Peter Steblin, the current General Manager, joined in 2002. It provides the opportunity to challenge the status quo at a very early stage in the decision process and engages the top levels of city leadership in the decision-making process at critical points.

In Fall 2006, Stantec Consulting was retained to participate in the workshop and subsequently undertake the design and construction of the MBR retrofit at the Oxford PCP. Tradition versus innovation With new experts added to the brainstorming process, the team was able to develop new expansion schemes including: • Activated sludge processes (ASP) with filtration and suboptions for carbon, nitrification, and denitrification.

• Biological aerated filters with filtration and suboptions for new aerated filter systems operating in parallel with or after conventional activated sludge (CAS).

• A new “greenfield” membrane bioreactor (MBR), working in parallel with the existing CAS, or a retrofit MBR to Section 2 operating in parallel with the existing CAS in Section 1.

• Trickling filters/solids contact tanks with filtration.

During the workshop, the city and its consultants compared the site-specific advantages and disadvantages of each of these options, ultimately concluding that the best two alternatives were to: 1. Expand the plant with a new activated sludge process (ASP) designed for carbon, nitrification, and denitrification with filters, and blend it with the existing Section 1 and 2 CAS effluents; or 2. Retrofit Section 2 of the plant with a membrane bioreactor designed for carbon, nitrification, denitrification, combined with existing Section 1 CAS effluent.

City officials and the revitalized group of consultants at the workshop then compared those two options, considering a number of key factors.

Location of the plant The Oxford PCP is located on the banks of the Thames River, upstream of

Wastewater the Delaware First Nation and adjacent to riverine habitat and planned recreational pathways. It also sits along a major arterial roadway (Oxford Road), which acts as an important gateway into the city, and is near several new, large residential areas and the prestigious Hunt Club golf course.

Because of the sensitive environmental and aesthetic contexts of that location, any expansion to the Oxford PCP must be completed in a manner that reduces the visual impact from Oxford Road, maintains the recreational value of the riverbanks, minimizes the impact on adjacent residential lands, and is sensitive to the concerns of downstream stakeholders, such as the First Nations.

An expansion plan needed to meet these “high-level” or long-term planning objectives as well as future expansions up to the ultimate build-out of 50,000 m3/d (50 MLD) flow. With this in mind, ultimate 50,000 m3/d capacity footprints for both the ASP and MBR options were prepared in order to compare potential impacts on the site and adjacent areas.

It soon became clear that the longterm impacts of an MBR plant would be minimal compared to those of the ASP option. The MBR plant requires a much smaller footprint, thus eliminating the need to expand into sensitive neighbouring lands and avoiding any visual impacts for traffic crossing the Oxford Street Bridge. In addition, the MBR plant generates higher-quality effluent, protecting the quality of the Thames River and offering future opportunities for water reuse. With less use of adjacent land, the MBR options would also have fewer impacts on riverine habitat and the future walking trail.

Suitability for a retrofit The Section 2 activated sludge plant was composed of two rectangular, twopass aeration tanks followed by three rectangular secondary clarifiers. The aeration tank and secondary clarifiers were well-suited to permit an MBR retrofit with only minor structural changes since the tanks, blowers, clarifiers, and pumping gallery areas were all large enough to accommodate the increased volume, equipment, and demands of an MBR system. These favourable conditions allowed for a reduced scope of work for a retrofit of www.esemag.com

Wastewater turers were invited to a pre-selection bid (GE Zenon, Kubota, and Siemens).

Challenging effluent limits The proposed effluent limits were a concern, particularly the low monthly limit of total phosphorus at less than 0.5 mg/L and summer total ammonia at less than 1.0 mg/L. Past performance at the plant suggested it would be challenging to achieve that phosphorus limit without tertiary filtration and that alkalinity could be limiting nitrification at times.

But with MBR technology, the plant could easily achieve a less than 0.5 mg/L phosphorus limit, and alkalinity concerns could be addressed by including anoxic zones in the aeration tank. A traditional activated sludge expansion, however, would require tertiary filtration, a second process step, which would unnecessarily increase the complexity, cost, and overall footprint of the plant.

Future applications A major consideration in the decision on whether to choose MBR or traditional activated sludge for the Oxford plant was its application for future expansions at the city’s largest wastewater treatment plant, the Greenway Pollution Control Centre. With MBR technology in place at the Oxford plant, the city could operate the system as a full-scale pilot test to confirm its operational and maintenance demands, train staff, and gauge its suitability for expanding the Greenway plant.

Comparable life-cycle costs Extensive effort was made to compare the capital, operation and maintenance (O&M), and life-cycle costs for an MBR retrofit versus a traditional activated sludge/filter expansion. The site specifics allowed the city to realize significant capital savings with an MBR retrofit, which would not have been possible with an ASP expansion. Also, reusing the existing structures avoided significant demolition costs and fit well with London’s solid waste strategy of reusing materials whenever possible.

The MBR retrofit enabled key costsaving opportunities: screening and degritting was undertaken in one step using rotary drum, 2-mm fine screens, existing infrastructure (tanks, equipment, buildings, etc.,) was reused, and the retrofit was integrated into existing infrastructure to minimize new construc54 | January 2008

tion and thereby reduce costs.

Additional MBR O&M costs were considered for membrane replacement, energy for air scour blowers, and chemicals for membrane cleaning. With a fiveyear membrane replacement frequency, the 20-year life-cycle cost for an MBR system was found to be comparable to that of conventional treatment solutions.

Affordability The MBR retrofit will achieve tertiary level treatment performance at a cost comparable to secondary treatment. The project was tendered in Fall 2006 for $21M. The design flow capacity for the MBR process is 13,500 m3/day, comprising 4,500 m3/day of existing flow and 9,000 m3/day of expanded flow capacity. On a per-unit flow basis, the resulting unit cost for treatment is in the range of $1,555 per 1,000 m3/day (or $7 per MIGD).

Creative thinking, creative solutions After comparing these various factors, the project team ultimately agreed that retrofitting the Oxford plant for MBR technology was the most efficient, economical, and responsible means for expanding the plant’s capabilities. And the solution couldn’t come too soon, as the city continues to face similar challenges in other areas where existing infrastructure is struggling to keep up with the growing demands.

By stretching the limits of conventionality and thinking creatively, the City of London was able to find a better solution for its treatment needs that now can serve as a model for many of Ontario’s wastewater treatment plants, particularly those that are considering expansions or changes to meet more stringent effluent limits. Construction of the MBR retrofit at the Oxford Pollution Control Plant is still under way, with completion expected in the spring of 2008.

Remediation

Challenges and opportunities to remediate closed landfill sites

By Fabiano Gondim and Craig Murdoch closed or operating landfill can release deleterious substances to soil, water and air that may pose adverse impacts to the environment and/or public health. The potential for adverse impacts is site-specific and is highly dependent on waste composition and whether or not engineering controls are in place. Landfill leachate and landfill gas are known as the main landfill by-products and are the main causes of potential environmental or health concerns.

Impacts from landfills may be varied and diverse; however, the greatest potential for impact can be broken down to a few major factors: • Liquid emissions (leachate) from landfills are shown to pose the greatest potential hazard for public health and the environment (Belevi and Baccini, 1992).

• Landfill gas emissions are also of concern, since they can migrate through the subsurface via pressure gradients and diffusion mechanisms, adding explosive gases to the subsurface environment.

• Trace concentrations of soluble volatile organic compounds (VOCs) present in landfill gas can migrate and

A

impact groundwater (Clister and Hihhs, 1998).

• Methane emissions to the atmosphere can contribute to global warming and trace odorous compounds from landfill such as hydrogen sulphide can cause off-site nuisance (odour).

Most closed landfills were sited before adequate engineered controls were commonly used, or were even thought necessary. Therefore, by present day standards, many landfills were not located in ideal locations, and were not equipped with low-permeability bases, leachate collection systems, landfill gas management, final cover or even stormwater management. Some landfills were constructed close to or in wetlands, creeks, gravel pits and quarries. As was common practice during this time, no preventative engineering controls were taken and little or no capital was spent on preventing environmental or health impacts during the operating life of the landfill.

With modern regulations and standards, closed landfills need to control or minimize environmental or health impacts, which can be achieved by close environmental monitoring and, where necessary, remediation projects. In sum-

mary, the goal of closed landfill remediation is to protect public health and the environment.

Landfill remediation strategies When a comprehensive landfill site investigation and monitoring program reveals leachate seeps, exposed wastes, slope instability, erosion problems, groundwater contamination or landfill gas migration, remediation strategies must be developed.

Closed landfills may or may not impact the environment and public health.

Depending on site-specific conditions, there are three possible outcomes for such a landfill: (i) a closed landfill may not require further actions if stakeholders agree that there are no risks to public health or the environment; (ii) a closed landfill may be removed, with all waste being excavated and landfilled at a location with acceptable environmental conditions; and (iii) remediate a closed landfill that is causing impacts to the environment or public health (Hauser et al, 1999).

Remediation strategies are driven by a number of factors, including waste composition and age, site-specific hydrogeology, distance to water courses, potential receptors, and site redevelopment plans.

Clay capping and landfill regrading have been the most used strategy for landfill remediation (Venkatraman and Ashwath, 2007). Clay capping provides a low permeability cover that reduces infiltration of water and subsequent vertical downward percolation and leachate generation. The second benefit of having clay capping is to prevent potential receptors from coming into contact with exposed waste. Proper cover grading also maximizes run off and decreases the infiltration rate into the waste mass.

Remediation strategies are assessed on a site by site basis where a closed landfill has caused off-site contamination and may include conventional regrading and capping, leachate collection and treatment systems, groundwater continued overleaf...

Environmental impacts from landfills can be varied.

pump-and-treat system, installation of permeable barriers with reactive material, slope stabilization, erosion control, and landfill gas passive or active control.

In rare instances, adjacent properties or groundwater rights may be purchased to ensure the closed landfill has a more extensive and effective buffer zone.

Performance of remediation systems The Ontario Ministry of the Environment often requires that the performance of remediation systems be assessed after construction completion or on a regular basis during operation. The capability of the remediation system to perform satisfactorily is typically assessed by collecting monitoring data and comparing this with historic data or quality standards and guidelines.

For example, the performance of a leachate collection system that controls leachate from being discharged into a creek can be assessed by checking water levels within the waste footprint and water quality of the creek upgradient and downgradient of the waste footprint and comparing with historic data prior to the installation of the leachate collection system.

Another example is the performance assessment of a passive venting system that is installed to control subsurface migration of landfill gas to adjacent properties. In this case, the performance is assessed by comparing monitoring data 58 | January 2008

at different locations and checking data from probes located between the passive system and the adjacent property.

A more qualitative approach is often used to assess the performance of leachate collection systems, landfill capping or erosion control projects by conducting visual inspections to detect leachate seeps or integrity of the landfill cover. The performance of surface water drainage projects can also be qualitatively assessed by conducting visual inspections during and after storm events to check if stormwater is properly drained as designed.

Hamilton’s experience with closed landfill site remediation The City of Hamilton is responsible for monitoring and maintaining 12 closed landfill sites. Eleven of these sites operated as municipal landfill sites in the six area municipalities that now form the City of Hamilton. All of these sites were closed by 1980 when the City’s current operating landfill, the Glanbrook landfill, started operation. The twelfth site, 87 Acre Park, was used for disposal of construction and inert-type waste up until approximately 2000, after which it was formally closed.

Remediation projects and sitespecific risk assessments Since closure of the landfill sites, various monitoring and remediation projects were implemented by the former Region

of Hamilton Wentworth (since merged with the City of Hamilton). A more comprehensive and intensive approach was taken by the newly formed City of Hamilton, Waste Management Division, since 2001, where a detailed review of the 12 closed landfill sites was undertaken and remediation projects were implemented as required for the sites. Site Specific Risk Assessments (SSRAs), or environmental investigations, were also completed or are at the final stage of completion for all 12 closed landfill sites (Stewart, 2005).

The City of Hamilton spent or committed $39,060,000 in a comprehensive remediation program for the 12 closed landfill sites from 2001 to 2007, (Table 1.)

Considering that the total waste footprint area is 72.7 hectares, the City of Hamilton spent approximately $540,000 for each hectare of waste footprint in closed landfill site remediation from 2001 to 2007. The City of Hamilton has been reimbursed for 50% of the total eligible costs from the Provincial Millennium Partnership Fund. Overall, the remediation undertaken has been capitalintensive; however, the resultant benefits of the protection of public health and the environment far outweigh the costs.

ave you ever seen a water buffalo? Ever wanted to be one? In the spring of 2007, I became aware of a group of motorcycle enthusiasts within the American Water Works Association, who call themselves The Water Buffalos. The dual purpose of this group is to ride to AWWA Annual Conferences, and to raise money for Water for People (WFP) by soliciting sponsors, pledges, and support for the ride.

I was intrigued, and contacted one of the riders for additional information.

Since the 2007 AWWA Annual Conference was being held in Toronto, they were very interested in having my participation and local knowledge. I joined the Buffalos, formed the Ontario Chapter, and offered to take on some local host and tour guide responsibilities.

In total, there were 13 motorcycles that made the trip from various locations throughout the continental United States.We had riders from as far away as Washington, Oregon, California, and Arizona. On Friday, June 22, we all met in Owen Sound and on Saturday morning it was my honour to lead the group into Toronto for the start of the AWWA conference.

In Toronto, we were warmly greeted by both the AWWA and WFP Boards of

Directors. Later, it was announced during the reception for WFP contributors that the Ride with a Purpose event had raised over $40,000.00.

On behalf of my fellow Water Buffalos who made this journey (in part for their love of motorcycle riding, as well as for the chance to raise money), thank you for supporting Water for People. We encourage you to continue to do so.

For those who are motorcycle enthusiasts, I highly recommend that you consider joining us for the third annual Ride with a Purpose to the 2008 AWWA Annual Conference in Atlanta, Georgia, this June. If you would like additional information about Ride with a Purpose and the Water Buffalos, or would like to sponsor me for the ride to Atlanta, please visit www.ridewithpurpose.org, or contact me directly.

Environmental Education

CCEE links post-secondary education to the careers of environmental practitioners

By Michael R. Moss ver the past 15 years the environmental profession in Canada has become defined, increasingly organized, and has developed its own standards, competences and procedures for professional certification at the national level.

The environmental sector is one of Canada’s more dynamic and faster growing fields of employment. The recently published Profile of Canadian Environmental Employment 2007 (ECO Canada, 2007) indicates that 530,414 people (3.2% of Canada’s workforce) are now employed in 105,221 organizations (10% of all organizations). In 2004 the workforce was 251,000, a figure that had grown by 13.7% since 2000.

The sector also has serious problems in recruiting suitably qualified people to mid and upper level positions, a situation compounded by the fact that 54% of environmental employees now in management positions are over 45 years of age whereas the national average is only 44%. Clearly employment of qualified persons in mid to senior level positions in the environmental sector presents many opportunities for career development and enhancement for suitably qualified people.

Unlike the engineering profession, however, the environmental sector faces many unique problems in terms of its identity and recruiting qualified people. Professional links to post secondary education and training are diffuse. They are relatively strong with the college sector, where programs reflect closely national occupational standards. But with the university sector, environmental education and training, because of its cross-disciplinary nature, remains relatively unstructured and unfocused. Many university

O

60 | January 2008

graduates need additional, focused, specialized training.

Furthermore there are many mid career professionals, now employed in the sector, who will need additional training and updating of their skills and knowledge in order to become professionally certified. Yet, given the career opportunities and the attractiveness of future employment, there are few opportunities for people currently in the workforce, or who wish to enter this sector, to have access to the necessary educational and training resources.

In common with other employment sectors, and given Canada’s current demographics, it is recognized that in order to confront the problem of a serious labour shortage, currently and in the coming decades, a major solution must

be through immigration. But there will need to be greatly improved methods of educating immigrants and, in particular, in the formal recognition of their academic credentials and the skills and competences of both recent and pending immigrants to Canada.

To come to terms with these inter-related problems, in 2006, the Canadian Centre for Environmental Education (CCEE) was established. The Centre is a partnership between Royal Roads University, British Columbia, and ECO

Canada, the Environmental Careers Organization of Canada. A major component of the funding and support for the Centre comes from the federal government through the Foreign Credential Recognition Division of Human Resources and Social Development Canada (HRSDC).

The CCEE (www.ccee.ca) brings together key elements from amongst a range of national and provincial resources. It relies upon the support of over 25 Canadian colleges and universities. These institutions provide access to their distance-based/on-line courses. Its first program, the Certificate in Environmental Practice, is delivered entirely in such a format. It is an accredited certificate awarded by Royal Roads University, a provincially-funded university in British Columbia with a mandate to provide applied and professional programs (www.royalroads.ca).

From the industry side, ECO Canada (formerly CCHREI, the Canadian Council for Human Resources in the Environment Industry) was established by the federal government in 1990 as one of 30 sector councils under Canada’s Sector Council Program. It is an autonomous organization whose mission is to ensure an adequate supply of people with demonstrated skills and knowledge to meet the environmental human resource needs of the public and private sectors. (www.eco.ca).

A critical element in this partnership is CECAB, the Canadian Environmental Certification Approvals Board, established by CCHREI/ECO Canada in 1997 and responsible for the professional certification of environmental practitioners in Canada. ECO Canada has now been accredited as an ISO 17024 body, thus meeting stringent in-

Environmental Education ternational quality standards and being eligible to perform audits.

Individuals, with at least five years on-the-job experience, and who can demonstrate that they meet or exceed the NOS (national occupational standards), may become certified as a CCEP (Canadian Certified Environmental Practitioner). The standards used are specific, employment-related competences. Persons who do not yet meet the five-year requirement or the full range of competencies may be designated Canadian Environmental Practitioner in Training (CEPIT) while acquiring the necessary additional knowledge and skills (www.cecab.org).

The CCEE, therefore, brings together several key, but previously disparate elements, as a national program responding to the needs of the environmental profession to support those seeking career advancement, upgrading and certification by furthering their education, training, and skills development. It capitalizes and coordinates the existing and potential resources of many Canadian post-secondary institutions with expertise in on-line/distance-delivery of specific, environmentally-related course materials.

From the perspective of employers, the Certificate in Environmental Practice will enable their employees to gain professional development opportunities. The distance-based, self-paced format allows employees to gain higher education qualifications, update their knowledge, progress toward professional certification and enter into new and evolving areas without having to leave their workplace.

Participants will have access to a wide range of options across the spectrum of environmental employment. There are 10 optional concentrations, each based on groupings of competencies identified under CECAB as national occupational standards. Hence, the course materials support the standards against which competencies are evaluated for professional certification.

The Certificate is deemed to be the equivalent of a senior university year.

Canadian college graduates, therefore, gain the equivalent of an additional year of academic credit, which may then be laddered to a final, one-year equivalent degree completion option. The Certificate will provide university graduates

www.esemag.com

with a professionally-focused certificate, and laddering options are being developed to provide an on-line Master’s degree. Many people, now practicing, do not have degree qualifications in the field in which they are working. The Certificate affords opportunities to redress such a problem where this may be critical for career development.

The immigrant sector, either recent immigrants or those planning to migrate, are provided with the opportunity to gain Canadian credentials, even be-

fore coming to Canada. The Centre will also assist them in gaining the appropriate recognition for their academic credentials awarded overseas. Relevant work experience, both for immigrants and domestic applicants, will be assessed against the occupational standards and credit awarded for this by the system known as prior learning assessment and recognition.

Health

Harmful chemicals found in popular children’s toys he Ecology Center, a Michigan-based nonprofit organization, has released the results of its testing of popular children’s toys for toxic chemicals at www.HealthyToys.org. Along with the Washington Toxics Coalition and other leading environmental health groups across the US, the Ecology Center developed this site to better inform consumers.

“The US government is not testing for toxic chemicals in toys, and too many manufacturers are not self-regulating, so several nonprofit organizations created the nation’s first toy database to help inform and empower consumers,” said Tracey Easthope, MPH, Director of the Ecology Center’s Environmental Health Project. “Ultimately consumers need to take action to compel the federal government and toy manufacturers to eliminate dangerous chemicals from toys.”

Shoppers can now easily search by product name, brand, or toy type (i.e.

T

62 | January 2008

dolls, teethers, jewelry, bibs, etc.) to learn how the products rate in terms of harmful chemical content. Babies and young children are the most vulnerable since their brains and bodies are still developing and because they frequently put toys into their mouths. While some

toys had high levels of chemicals such as lead, cadmium, and arsenic, others were free of these harmful additives.

Researchers chose to test for these particular chemicals because they have been associated with reproductive problems, developmental and learning dis-

Health abilities, hormone problems and cancer, and because they are found in children’s products. The testing was conducted with a screening technology, the portable X-Ray Fluorescence (XRF) analyzer, which identifies the elemental composition of materials on the surface of products.

HealthyToys.org tested 1,200 children's products and more than 3,000 components of those products. The following are highlights of their findings: Lead When children are exposed to lead, the developmental and nervous system consequences are irreversible. Recently the American Academy of Pediatrics recommended a level of 40 parts per million (ppm) of lead as the maximum that should be allowed in children's products. Nevertheless, there are no federal regulations for lead in vinyl or plastic toys or children’s jewelry. The only existing standard is for lead in paint. HealthyToys.org found lead in 35% of all the products tested. Seventeen percent (17%) of the products had levels above the 600 ppm federal recall standard used for lead paint!

Polyvinyl Chloride (PVC)/ Vinyl HealthyToys.org determined if products were made with PVC plastic by measuring their chlorine content. Phthalates are chemicals that are very commonly added to PVC to make it soft and flexible; however, they can leach out of the plastic. Exposure to phthalates is linked to birth defects of the genitals and altered levels of reproductive hormones in baby boys. There are currently no federal regulations limiting phthalates in children's products. California recently passed a ban of several phthalates in children’s products, and Europe has restricted the use of phthalates in children’s toys and child care items. Forty-seven percent (47%) of toys (excluding jewelry) tested by HealthyToys.org were made with PVC. Cadmium Cadmium is a heavy metal that is used in coatings and pigments in plastic and paint. It is a known human carcinogen and exposure can cause adverse effects on the kidneys, lungs, liver, and testes. Currently there are no mandatory restrictions on cadmium in children’s products in the U.S. HealthyToys.org found cadmium at levels greater than www.esemag.com

100 ppm in 2.9% of products – 22 of the 764 products tested for cadmium – including painted toys, PVC toys, backpacks, lunch boxes and bibs.

HealthyToys.org also tested toys for arsenic, mercury, bromine, chromium, tin and antimony – chemicals that have all been linked to health problems and have been subject to either regulatory restrictions or voluntary limits set by industry associations or third party environmental organizations.

The good news is that safe toys are

possible. Twenty-eight percent (28%) of the products tested did not contain any lead, cadmium, arsenic, mercury or PVC, including many made in China.

Examples of healthier toys include: Amazing Animals Hippo by FisherPrice (made in China); Caterpillar Grasping Toy, Melissa and Doug (made in Vietnam); and B.R. Bruin Stacking Cups (made in China). These results show that manufacturers can make toys free of unnecessary toxic chemicals.

SCADA installations for small systems

By Paul Bulmer

SCADA system is used to control a process such as a sewage pump station or a water booster station. All control systems have the ability to allow an operator to view and control the process through an operator interface.

Control systems collect data, record the data in trends and all control systems have an alarm function that notifies the operator that something needs attention.

This control system has a brain – the controller, which is where the control system processes data, makes decisions and results in some kind of action such as opening a valve or turning on a pump – and it has the ability to connect to various types of sensors, like pressure transmitter or level transmitter, to collect data such as temperature, pressure, level, etc.

These are called inputs. And it has outputs which allow the control system to manipulate devices such as turn on and off pumps or open and close valves, etc.

The control system needs to have a means by which an operator of the process can interface with the control system so as to observe what the process is doing and to control the process through the control system.

Today an operator can interface with the control system via a human machine interface or HMI, which is just a fancy term for a computer screen. This HMI is located in a convenient location such as your desk top or on the front of a control panel. With today’s technology, an operator can access the control system from pretty much anywhere via a phone line or the internet or wireless hand-held

A

64 | January 2008

devices such as a PDA (personal digital assistant), blackberry or cell phone.

A simple control system will have one contoller/brain in one location such as a pump station. On a large control system you can have several brains/controllers and they can be located in several locations. These controllers are normally connected together by a cable so they can communicate and share data and share the tasks that they are performing. This is called a distributed control system or DCS. The operator sits at a central station viewing the process through the HMI which is run on the central station computer that performs the functions for alarming, trending, etc.

The best way to understand a SCADA system is to think of it as a control system with one exception.

Some of the controllers at the pump stations are located a long way from where the operator is located, which makes it difficult to connect to that controller because it is just too far to run a cable between the operator station and the controller.

So what do we do? We communicate to the controller via another means such as a telephone line or a radio signal.

This communication between parts of the control system over long distances is called telemetry. This telemetry is what makes this control system unique.

Because it is unique we can’t call it a control system, so someone came up with Supervisory Control and Data Acquisition - SCADA. Do I need a SCADA system?

You may be asking yourself “do I

need a SCADA system?” The answer is a resounding yes.

No matter how small your municipality, you can afford a system. Due to advances in technology, control systems are getting more powerful and cheaper.

They pay for themselves very quickly.

Since they are computer-controlled they are very dependable and reliable if designed properly. They eliminate the need for operators to run around collecting data or checking on the status of the system, etc. Labour costs savings alone are substantial. They also help to eliminate human error.

The system will help keep you in compliance if you are a small water supplier. It will ensure your water is chlorinated and will alarm you if it isn’t. It will collect important data to help you make operation and maintenance decisions.

Determining needs and costs Once you have decided to utilize a SCADA system, you need to know what type of system you require and what the cost will be. You can hire a consultant, a systems integrator, or a vendor who supplies SCADA, to tell you this. There are lots of companies out there who can help you but ‘beware’. Some claim to be SCADA experts, but they are not.

Again do your reference checks. If they are experts then they will have a long history of SCADA projects.

If you are only trying to get a handle on the ballpark cost so you can budget for the project, an experienced consultant can tell you roughly what you will need and roughly what it will cost in just a few hours. They will be able to deter-

Plant Operations mine this by simply asking you some questions, viewing your existing equipment and discussing future growth, etc.

Selecting a SCADA system You should prepare a specification yourself, a simple basic one that determines what you want the SCADA system to do for you, or, if you have the budget, hire a consultant.

Take into consideration the big picture. How fast is your community growing? How expandable will the system need to be? How old is the technology?

What is the life cycle of the system?

When will you need to upgrade the hardware and software? Make sure you plan for the inevitable expansion.

For a small system it would be wise to select the remote terminal unit (RTU) at the pump stations and the HMI software at the central station from the same manufacturer. If you choose different manufacturers and you upgrade the software to its next version (which always happens) and you experience difficulties communicating to the RTU, the software manufacturer may tell you the problem is with the RTU and the RTU manufacturer will tell you the

www.esemag.com

problem is with the software.

Make sure your system (the central station as well as the remote control stations) has the ability to be remotely accessed via a phone modem. This will allow for the consultant or systems’ integrator or the manufacturer of the hardware and software to assist in troubleshooting the system remotely over the phone.

Since you are a small municipality with the need for a small SCADA system you may want to consider a system that is off the shelf and comes almost completely engineered.

Ask your peers if you can have a copy of their evaluation; they should be more than happy to share it with you.

Ask them what they did to implement their SCADA projects, what problems they came across and how they overcame them and what it cost.

Sewage pump station controls You should standardize and make all your pump stations’ controls the same whether in a kiosk or in a building. The controls are performing the same function, turning the pumps on and off, collecting some data and sending it

through the SCADA system. Keep it simple. Hire someone to create a design that will work for all your pump stations. This way you will pay for the design once and build it several times, saving you substantial design costs.

Also, with the same hardware and logic in each control system, you will have less spare parts to deal with.

Your operators will find each station will look and operate the same which is less confusing, requiring less training.

Maintenance and troubleshooting will be a lot easier. If you do go the design, bid, build route, use the same design for each tender. Each time you go to tender give the consultant the pump station control design drawings and specs and instruct them to use them.

By having the same parts and operation you will have the same inputs and outputs to the controller and this will result in having the same logic, making the system simpler.

Infrastructure

Plan unveiled for infrastructure spending in Québec

By Yasser Bouhid ate in 2007, the Government of Québec unveiled the Québec Infrastructure Plan (the Plan), which provides for $29.7 billion in investments for public infrastructure over the next five years. As a framework for such investments, the President of the Conseil du trésor tabled An Act to promote rigorous management of public infrastructures and large projects (Bill 32) in the National Assembly on October 30. The investments will, for the most part, be used to modernize and repair roads, hospitals, schools and municipal infrastructure. Funds will also be allocated to public transit, public housing, public security, culture and research. $30 billion for infrastructure By investing in the Plan, the Government of Québec hopes to eliminate the public infrastructure maintenance deficit accumulated over the past decades.

Within the next 15 years, the government anticipates being on par with the rest of Canada and the United States in this re-

spect. Investments of $23.4 billion will be used to renovate assets and bring them up to acceptable standards. Another $6.3 billion will be invested in improving and replacing infrastructure. In addition, $7.6 billion has been budgeted to complete existing projects. The bulk of expenses will go to the transportation ($11.8 billion),

October 31, the Minister of Health indicated that approximately 2,600 buildings within the health care system will be renovated and modernized thanks to $4.6 billion in financing. The remaining $2.5 billion will be used to finance existing projects, such as the Centre hospitalier de l’Université de Montréal (CHUM), the

Projects financed with the allocated funds will be announced by the Ministers responsible for the relevant sectors. On

McGill University Health Centre (MUHC), the Sainte-Justine University Hospital Centre and the Centre hospitalier universitaire de Sherbrooke (CHUS).

On November 2, the Minister of Municipal Affairs and Regions announced in-

Infrastructure vestments of $1.2 billion to improve water treatment and purification facilities and a further $1.95 billion will be used to renovate other municipal assets.

Bill 32 The purpose of Bill 32 is to promote the development and proper maintenance of public infrastructure and to require future governments to invest in such assets in order to eliminate the maintenance deficit within 15 years. The Conseil du trésor would be called upon to submit to the government, on an annual basis, a capital budget for public infrastructure extending over several years and specifying the amounts allocated to each of the three following objectives: (1) maintenance of existing infrastructure, (2) elimination of the maintenance deficit within 15 years, and (3) improvement or replacement of infrastructure.

Under Bill 32, the President of the Conseil du trésor or the Minister responsible for a public body may later request that such public body provide all information deemed necessary to establish the capital budget and an annual report detailing how the allocated amounts will be used. Finally, the capital budget and the annual report would be tabled by the chair of the Conseil du trésor in the National Assembly for review.

Bill 32 also provides a governance framework for large-scale projects in order to reduce cost overrun risks and delays in project completion. To that end, the quality of such projects must be reviewed independently. Accordingly, a ministry or other public body considering a large-scale project (any project valued at $40 million or more) must evaluate such project together with the Agence des partenariats public-privé du Québec (the Agency), which will assess the quality of the business case and make recommendations on the preferred approach. If a project is not carried out as a public-private partnership (P3), a committee of independent experts shall be responsible for providing an opinion and making recommendations on the business case.

The Government of Québec’s new approach is similar to the one adopted by the Government of British Columbia, whereby any infrastructure project of $20 million or more must be reviewed to determine whether it should be completed under a P3 model or in the tradiwww.esemag.com

tional fashion. The role of the Agency, which was established in 2005, includes advising public bodies on the feasibility of P3 projects, assisting them in selecting partners and negotiating, entering into and managing the contractual framework of P3 projects. By providing advice and expertise, the mandate of the Agency is to assist in renewing public infrastructure and improving the quality of public services through P3 projects.

Conclusion The investments and Bill 32 men-

tioned above have been favourably received by most of the principal actors, including municipalities, school boards or groups of professionals such as the Réseau des ingénieurs du Québec. The government will require the support of at least one of the opposition parties in order to have Bill 32 passed into law in the National Assembly.

Cover Story

Mapping sewers using dye tracing techniques

By John Spencer, CET oday’s owners and operators of underground infrastructure, including sewer collection and conveyance systems, face increasing pressure from municipal bylaws and environmental legislation to demonstrate an understanding of their sewer systems. Typically this is demonstrated by use of sewer system mapping or drawings. However, in many cases, maps or drawings do not exist or changes to the infrastructure have been made that were not recorded.

Frequently, in the case of industrial/manufacturing facilities, owners cannot identify where a sewer system is located, what it is connected to, what sources of effluent are contributing to the sewer or where it discharges. Often the information that can be located is out of date or does not reflect changes to the sewer infrastructure or operations that have occurred in a “piecemeal” fashion over time, creating a need for more accurate drawing information.

Most municipalities have a sewer use by-law in place that regulates discharges to the municipal sewer system. Dischargers making new connections or changing effluent characteristics are required to obtain an approval from the regulating authority and disclose the effluent quantity and quality to “characterize” the effluent.

In characterizing effluent, problems often arise such as flow volume exceeding the anticipated discharge volumes, or effluent quality not meeting acceptable discharge criteria required by the sewer use by-law. When these problems occur, a sewer discharger is put into a position of demonstrating an understanding of the sewer system infrastructure being operated to enable him to identify and qualify point sources of discharge into the effluent stream. This leads to a need for locating the in situ sewer infrastructure and, if necessary, to meet compliance by eliminating sources of extraneous flow.

Some examples of extraneous flow include: direct sources of discharge such as catch basins and rainwater leaders; indirect sources of discharge such as leaking sewer pipes and high groundwater tables; or possible contamination from process operations or sewer cross-connections.

Dye mixing in a pail on the surface being poured into a deep, dark sewer to gauge concentration based on available light.

In addition to sewer use by-law compliance requirements, owners may need to inventory or map sewer systems for other purposes such as real estate transactions, insurance requirements, meeting ISO 14000 environmental standards, responding to public complaints, or for complying with orders issued by provincial ministries.

One of the first elements for mapping a sewer system is to identify the sewer type being operated and managed and the sewer catchment area. Often this is in the form of drawings or maps which illustrate the known elements of the sewer infrastructure that are connected to a sewerage system along with the sewer discharge locations.

In most cases municipal operators have an advantage over private system operators since municipalities require updated drawings to record improvements that have been made. Privately owned systems are not usually subjected to frequent improvements, including updates to the associated drawing information.

Therefore, map and drawing information illustrating private sewer inventory is often found to be very old and not reflective of changes that have taken place above and below ground.

To address the information gaps and to assist the understanding and identification of sewer types and alignment, the collection of information for updating sewer drawings and mapping is a relatively easy process, which can utilize a simple approach such as dye tracing/testing.

The dye tracing/testing approach has been used by a number of industrial/manufacturing facilities throughout Ontario who have commissioned R.V. Anderson

Associates (RVA) to assist them with developing an understanding of their sewer infrastructure and/or production of accurate sewer drawings. Additional information such as sewer system integrity and hydraulic condition may also be observed while accessing the sewers for dye tracing/testing activities.

Some of the advantages include the use of little, or inexpensive, or simple monitoring equipment, and the lack of necessity for conducting a confined space entry procedure requiring safety equipment, lock out procedures or entry permits into enclosed areas. Simple tools such as a pick or pry bar to remove manhole/catch basin covers, a flash light (or mirror to reflect sunshine), a watch to record time, air testing equipment to test for gases in sewers (prior to removing a manhole cover) and the appropriate coloured dye are all that are required.

Other methods of mapping sewers and connectivity are available and include acoustical sounding, electrical impulse measurements, ground-penetrating radar, smoke testing and observing floating objects placed into the sewer from a known upstream location. However, the use of dye tracing is usually the easiest, fastest and most economical procedure when access to a sewer is available.

To conduct a dye tracing exercise either inside a facility or within a right-ofway, the first task is to locate available site drawings or mapping information that identify and illustrate sewer infrastructure alignment located in the adjacent area. Where these are not available, basic line sketches, tied into fixed points (existing infrastructure features such as manholes and catchbasins) may be pre-

Cover Story pared. These drawings and line sketches should be considered as preliminary draft base plan mapping for field use applications.

Another source for developing preliminary draft base plan mapping, particularly for industrial/manufacturing facilities, is structural column drawings.

Most industrial facilities will have a reasonably accurate set of structural drawings that often include building column drawings which may be utilized for developing a base plan map by locating sewer infrastructure (manholes and catch basins) to adjacent numbered columns.

Once a draft base plan drawing is available, a field reconnaissance survey is carried out to compare/locate in situ sewer features with the drawings and develop a preliminary alignment and feature identification system for the various sewer types. For industrial facilities there are often three types of sewers being operated and managed: process, storm and sanitary sewers. For municipalities, often storm and sanitary sewers make up the sewer infrastructure.

Verifying information from the field is the next procedure. From the field reconnaissance survey, the first level of drawing information accuracy becomes

apparent and infrastructure features are found at the approximate locations shown. In the case where changes have been made, features may not be shown or are nowhere to be found in the vicinity depicted by the drawings. In these cases and when base plan drawings are developed in the field, sewer infrastructure features are plotted at approximate locations and a feature identifier assigned for future reference when spatial information is developed.

To spatially locate and verify sewer infrastructure features and access points, a typical practice is to conduct a topographic survey using total station (TSS), global positioning (GPS) or baseline offset procedures. In the case of a manufacturing facility where much of the sewer inventory is under roof, measuring (“tying in”) sewer infrastructure features from fixed positions such as the building columns provides a quick reference and a ready-made base plan drawing when structural column drawings are available.

The spatial information collected in the field may be input into AutoCAD to develop a base plan drawing/map or to upgrade existing information of the area, which has been defined by the

field reconnaissance and survey.

Once the base plan drawing has been developed the underground sewer connections may be verified using the dye test/tracing technique.

In preparation for dye testing and in addition to preparing the draft infrastructure drawing for verifying sewer connections, other basic criteria are required, including: • Identification of the proposed test location and sewer alignment; • Anticipated elapsed time of travel between access points; • Identification of features where dye will be placed and where observations will be made; • Type and colour of dye media to be used for test; • Notification to proper authorities of when and where a dye test will be carried out and the anticipated discharge locations where dye coloured effluent may be observed.

In applications where dye will be used in potable water sources, dyes and procedures will need to conform to ANSI/NSF 60 standards. The selected dye colour is an important criterion to bear in mind, since the colour will be continued overleaf...

Cover Story impacted by the type of effluent being tested. Avoiding areas where an intake location is close to a discharge location or where a sensitive aquatic ecosystem is located is a concern owners conducting tests should consider prior to commencing dye tracing/testing.

The visual detection of dye, under ideal conditions, is possible in concentrations of 100 ppb (parts per billion). In some cases a black light or fluorometer, used to measure concentrations of dye in water or effluent, is used to make observations. For the situations that RVA has faced in most industrial and municipal dye tracing studies, visual observations from the surface have been quite acceptable.

The optimal choice of dye colours for conducting tests will become apparent as tests are attempted. RVA has successfully used colours such as: yellow green (fluorescent) where observations are in deep and dark locations, red for relatively short test runs with moderate light conditions and blue/purple for good light conditions.

If multiple dye tests are to be conducted upstream of an observation point, it may be necessary to use various colours to differentiate one test from another. Alternatively, tests may be undertaken with enough time between tests to allow the sewer conditions to return to normal appearance and colour. This elapsed time is dependent on flow conditions and usually does not take too long.

Dye used for tracing/testing comes in a number of forms: powder, tablet, liquid, pucks, cakes, cones and donuts. The

Result of the dye concentration at a downstream observation point which has verified the connectivity between the locations where the dye was poured into the sewer and the location it has been observed.

powder, tablet and liquid form are typically used when tracing a sewer between access points (manholes) or verifying the connection of a process discharge, a floor drain, catch basin or any suspect connection to a sewer. These types of dye media dissolve rapidly and may be placed directly into the upstream location or dissolved in a pail of water then placed into the test location. Pucks, cakes, cones or donuts are used were sustained concentrations of dye are required to carry out a test over a longer period of time.

To test a sewer access point or process connection, some assumptions will need to be made to determine where dye will appear after it has been placed into a drain or pipe. The reconnaissance done before the commencement of testing will help to identify the most likely location that dye will be observed and,

therefore, where to place an observer. A quick assessment of flow to determine a relative flow velocity will assist in estimating how long a dye test may take from the point where dye is placed in the flow to where observations are made. In most cases the testing can be completed by two people, one to inject dye and record a time, and another to act as an observer.

Prior to commencing testing, communication between the people conducting and observing the tests should be arranged. This may be done using radio communications, hand signals or agreeing to a time when dye will be placed into a sewer.

The appropriate coloured dye is then placed into an access location such as a manhole, the manhole feature identifier is located on the prepared base plan drawings and the downstream location where observations are made is verified when the observer has visually observed the dye-coloured effluent as it passes the point of observation. Once again, the base plan drawing is consulted and the sewer connection is verified from one point to another.

This process is repeated throughout the sewer catchment area until all features within the test area have been physically located, spatially identified and the connection between features verified by dye tracing/testing and the result recorded on the base plan. The base plan now becomes a model for updating existing drawing inventory or for the production of accurate, up to date sewer infrastructure drawings and maps.

Waste Management

Newfoundland waste management site to service half their population View of St. John’s.

ewfoundland’s Robin Hood Bay has been confirmed as the full-service regional waste disposal site for the Greater Avalon Region. In accordance with the Provincial Solid Waste Management Strategy, the site will be retrofitted and fully operational by 2010.

"The landfill will be retrofitted to include a materials recovery facility, a commercial indoor composting operation and leachate collection and treatment system," said Dave Denine, Minister of Municipal Affairs. "We have already begun working with a number of municipalities to begin the process of regionalizing waste management and make preparations for the transfer of waste to Robin Hood Bay." Currently, Robin Hood Bay handles about 80 per cent of the waste produced in the Greater Avalon region. When complete, the site will service over 250,000 people, approximately half the total population of the province.

The life-span of the facility is projected to be approximately 40 years.

The overall cost of developing Robin Hood Bay as the regional site is estimated at $38.5 million. Approximately $6.5 million has already been committed by the City of St. John’s for preparatory work for the facility. Beyond the city’s contribution, the capital cost of developing the waste system will be absorbed by the province, with municipalities and users paying tipping fees to cover operational costs.

The integrated facility will generate sufficient revenue to offset all operating costs. The new retrofitted site will be able to accommodate multiple waste streams.

The City of St. John’s is currently piloting

N

a waste diversion program which encourages participants to separate their recyclables and organics from their regular garbage. Other municipalities will determine the number of streams they will contribute to the waste system, but as a minimum, users will only be required to separate organics from the waste stream to meet the minimum requirements of the Provincial Waste Management Plan.

While tipping fees for household waste will be uniform for all municipalities, fees for organic and recyclable materials

will be lower than waste destined for the landfill site. The Provincial Government’s plan will ensure that a municipality in the Greater Avalon Region will not be required to pay to transport their waste any further than 100 kilometres in order to access either a waste site or a transfer station.

Tenders will be awarded in the near future to continue to retrofit the Robin Hood Bay landfill to support the move to become the regional site.

Wastewater Treatment

Recent developments in carbon pollution abatement

By D. Lamarre, A. Gadbois, C. Scott, D. Oliphant iologically aerated filters are compact treatment processes, which combine filtration and aerobic/anoxic/anaerobic treatment using fixed-film biodegradation. They consist of an immersed biological filter operating either in down flow or upflow hydraulic condition.

They are used to remove TSS, COD, BOD5, NH4-N and NO3-N, either as a secondary or tertiary stage. Their filtering properties can also be used to remove phosphorus. The filter medium is periodically backwashed to remove suspended solids retained during the filtering interval and excess biomass produced within the filter bed.

The development of biologically aerated filters (BAFs) has spanned the last 20 years. This article presents the latest innovation in the application of BAFs for carbonaceous pollution abatement.

Nitrogen abatement using an upflow BAF Conventional activated sludge treatment degrades the nitrogen through the biological activity in the activated sludge. This technology is well known and mastered. Its main drawbacks are the large footprint required for treatment and lack of elasticity of the treatment toward concentrations above the design loading.

B

The BAF technology is a hybrid technology that builds on the benefits of both conventional activated sludge biological treatment and of fixed-film biotreatment and subsequent filtration.

This is achieved through an upflow BAF using a floating polystyrene media comprised of individual spherical beads.

The beads are approximately the same size, according to uniformity specification. The diameter of the beads originally used for nitrogen abatement is 3.6 mm, which provides a large specific area (>1,200 m2/m3 or 400 ft2/ft3) for biomass attachment and retention of suspended solids. With these small beads, the biofilm surface area and subsequent volumetric loading capacities and removal efficiency are very high.

There are close to 150 references for this technology around the world (US, France, Germany, England, Italy, Spain, etc.) for nitrogen removal in municipal wastewater applications. The first two Canadian Biosty® biofiltration units are currently in construction (Kingston WWTP in Ontario and Boisbriand WWTP in Québec).

Kingston upflow biofiltration unit In 2008, the Kingston Ravensview WPCP will commission its new biofiltration facility. Wastewater treated by

the Biostyr system will first undergo primary treatment, including a 12 to 15 mm screening, and primary clarification. The biofilters are designed to achieve BOD and TSS removal, as well as partial nitrification of the incoming nitrogenous compounds.

The main design parameters of the system are described in Table 1 and the effluent requirements are shown in Table 2.

In order to achieve these goals, a set of 11 Biostyr cells, each using a surface of 147 m2 was provided. The height of each filter bed is 3.5 m. One cell is considered to be out of operation at all times, meaning one cell could be in a permanent stand-by mode. When one of the remaining 10 filters is in backwash mode, the system is thus operating at N - 2 filters, so nine filters are in filtration mode.

Carbon pollution removal using an upflow BAF Over the last five years, further research and development of this technology has led to its use as a cost-effective solution for compact wastewater plants for carbonaceous pollution. Due to the high solids and BOD content of the primary effluent, upflow BAFs for carbon removal do require a larger floating media to maintain a low head loss and to store the increased sludge production.

Consequently, the diameter of the floating media has been increased for carbon abatement applications. Moreover, the media should be small enough to ensure the filtration effect of the media bed. The floating media diameter is, therefore, selected for each project, optimizing each specific situation.

Also, in order to reduce the solids and BOD load reaching the BAF, chemically enhanced primary treatment (CEPT) often precedes the biofiltration step. Indeed, effective primary treatment is needed to meet the effluent guarantee without over-sizing the BAF units. The purpose of the clarifier is to remove as much particulate matter as possible to keep the volumetric TSS load below 2.0 kg/m3/d. This loading value typically ensures a backwash interval above 24 hours when the COD

The CEPT most often used with this type of upflow BAF is a lamella plate settler (Multiflo®) or a ballasted flocculation process (Actiflo®), the latter providing the most compact primary treatment solution.

Backwash water rinse velocity varies according to the media size. Waste backwash is temporarily stored in a surge tank or mud well. From there, the

waste backwash is either treated separately or blended with the raw water before entering the primary clarifier units.

Several plants in France and other countries have already been upgraded to meet new, more stringent carbon discharge limits. Based on the combination of CEPT and BAF, these new plants achieve carbon removal down to 25 mg/L both for BOD and TSS. Givors Wastewater Treatment Plant The Givors wastewater treatment plant in the south of France has a 90,000 population equivalent. To achieve this, the WWTP required the installation of five units of 42 m2 of footprint. Figures 2 and 3 show the BOD5 and TSS concentrations from the plant during the first five months of operation in 2005.

The BOD5 and TSS discharge limits were maintained even though there were large variations in the influent BOD and TSS. The upflow BAF process treats the effluent of a CEPT, using lamella plates to minimize the footprint of the plant.

The first full-scale installations using this novel application have been successfully built and commissioned in Europe.

What have bottled water, dental cavities, plastic bottles and coaching advice got in common?

By David Clunas ow, why would you want to read about a list of items as mundane as bottled water, dental cavities and plastic bottles?

Apparently dentists have noticed something. Believe it or not when they are checking out your teeth and gums they also see a bigger picture. Some dentists believe that the alarming increase in dental cavities in children may be related to bottled water. Not all dentists agree on this potential cause and effect. But why would any dentist who has completed many years of scientific and medical training make a non-scientific statement like ‘there may be a link between cavities and bottled water’?

Maybe they have children that play soccer or baseball and have witnessed the incredible number of empty plastic bottles littering the field as they arrive and the increased number of bottles after the game is over. Perhaps they mindlessly look at the recycling boxes as they arrive to work in the morning and note bins overflowing with water bottles. Possibly they have walked by isles of bottled water in grocery stores and have seen the strain on the faces of people hauling the water to their cars.

You do not have to be a dentist to see the quantity of bottled water bought, consumed and the collection of bottles resulting from the consumption of bottled water.

Question: Do people realize that most bottled water is pumped from groundwater sources, trucked to a bottling plant, ozonated (a form of disinfection), bottled, packed in shipping crates, moved into a storage area, trucked to a store, driven home by a consumer and finally drunk in a moment of need?

That’s a lot of effort for something that you can get for almost no cost from your kitchen tap. I won’t discuss the price of bottled water but I know you pay a lot more per litre as compared to tap water.

But tap water is something special – it is provided to most people at a very low cost and was started over 100 years ago to prevent the spread of waterborne diseases that affected whole towns and

cities. Once we figured out that disinfection of water significantly improved the health of people, the concept was embraced across the world. We may not have achieved clean water for all people (i.e. third world countries) but we know the health benefits are clear.

In addition, at some time a clever person (maybe a dentist) noted that a little extra fluoride in water reduced the number of cavities in people and now we have fluoride in most municipally supplied water and toothpaste.

Coaching advice • Avoid the apparently impressive “dash and flash” actions of some athletes.

• Consider the use of more reliable and consistent athletes to avoid the waste of energy and time to improve the team.

• Remember that there is always another year ahead so ensure all your athletes improve for the upcoming season.

Now switch the word “athlete” to “product”, changing the above advice to create some product advice.

Product advice • Avoid the apparently impressive “dash and flash” actions of some products.

• Consider the use of more reliable and

consistent products to avoid the waste of energy and time to improve the team.

• Remember that there is always another year ahead so ensure all your products improve for the upcoming season.

Let’s take a moment to see how the product advice applies to bottled water.

Bottled water suits our “dash and flash” life style and is quite often considered superior in social situations – that is supposed to be avoided.

Bottled water is reliable and consistent but its production and consumption are very energy intensive. This has a direct link to energy use, greenhouse gases and climate change – these are supposed to be avoided.

Bottled water processing and shipping requirements will not change over time but we could better promote the quality and safety of municipally supplied drinking water for upcoming years and future generations of people – that is achievable.

It seems that bottled water, dental cavities and plastic bottles have a significant linkage and that with a little bit of coaching advice we could reduce health care costs, the amount of energy used moving material that is readily available at your kitchen tap, avoid the litter and recycling issues with plastic bottles, leave groundwater in place for agricultural usage and all contribute to a reduction in greenhouse gas emissions/ climate change by one simple action – discourage and reduce the use of bottled water.

Just think about it as your children smile, visit the dentist, consume that bottled water at soccer, trip over the plastic bottle litter and prepare to deal with climatic change that has not been experienced to the same degree by any previous generation.

Oh, and by the way - health professionals, governments at all levels, industry representatives and even individuals are free to use and apply the product advice in this article.

Biosolids Containment

Québec farmers install new hog manure containment system s the size of Québec’s hog industry has exploded over the past 25 years, so has the number of waste containment tanks used to store manure for subsequent use as fertilizer. Census statistics estimate that there are upwards of 6,000 of these tanks in the province.

The expansion of Québec’s hog industry, which represents $3 billion in revenue and 40 percent of Canada’s total pork export business, has prompted the provincial government to study the impact of livestock operations and its phosphorousladen manure supply on water quality.

In 2002, water quality concerns and public complaints over manure odour led the Québec government to grant rural municipalities control over the development of hog farms in their territory. Many suburban neighborhoods are within a kilometre of hog farms.

Increasingly strict governmental regulations regarding hog waste containment are leading many farmers in Québec to

consider new options for manure management. Early in 2007, the Robitailles family contacted Paul Larouche of Agri-Ventes Brome about installing new covers on 40 of their hog waste containment tanks.

The Robitailles wanted to use their largest liquid manure containment tank, which has a capacity of 3.2 million litres, to test a cover that could eventually be

used on all of their tanks. The three most important requirements for the cover were that it contain odour, keep rainfall out and be cost-effective. Mr. Larouche ultimately recommended fPP-R Geomembrane by Firestone Specialty Products, which is a reinforced polypropylene membrane with puncture resistance and tensile strength, and is said to be ideal for exposed applications, due to its UV, oxidation and ozone resistance.

Unique system design Designing an effective cover for the concrete tank had its challenges. First, the flexible cover could not sag to the bottom of the tank during times of low content. Before the farmers can spread fertilizer onto the fields, they have to pump manure off the bottom of the tank and then pump it back in onto the top of the manure. This process mixes the manure. If the cover is in the way, this mixing process would become difficult and could damage the cover.

To prevent excessive sagging, AgriVentes Brome designed a system of 25 straps to criss-cross the top of the tank.

Each strap has its own winch that can be tightened, or loosened, depending on the manure level. The design allows the membrane to rest on top of the straps, keeping the membrane a minimum of eight feet above the tank floor at all times.

A tight seal was imperative, not only to keep odour in, but to prevent rainfall from entering the tank. “We average 900

mm of rain each year here, which equals a quarter of the depth of this particular tank,” Mr. Larouche stated. “If that much water was added to the manure, the resulting fertilizer would be tremendously diluted and not nearly as valuable to the farmers.”

Cover installation The project began in September 2007. The first step was to drain and clean the tank. Then, a thick, felt protection mat was laid on top of the concrete walls around the perimeter of the tank to protect the straps and cover membrane from friction damage. Next, the 25 straps were stretched at regular intervals across the tank and attached to powerassisted cranking tools mounted into the exterior concrete walls. Smooth plastic sleeves were slipped over each strap at

the point where they rest against the tank for added protection from wear.

Once the straps were securely in place, the tank was ready for the cover installation. Two 23-metre by 46-metre, 1.1 mm thick (45-mil) fPP-R Geomembrane panels arrived onsite, and were unfolded to their full length and overlapped. A protective layer of geotextile and fiber board was installed at the seam overlap for added strength. Then, a robot welder was used to heat-weld the 46-metre seam, which was completed in just 20 minutes.

When the seam was set, the 2,100square-metre membrane was lifted with a crane and positioned over the centre of the tank. It was then unfolded toward one side of the tank and then toward the other side.

After the cover was in place and draped over the sides of the tank, the

membrane was folded up and under a plastic strip to prevent water access.

Then, an aluminum strip was installed above this pocket fold and bolted into place at 300 mm (12-inch) intervals around the tank’s perimeter.

“This fastening system actually locks the membrane into place because the plastic strip cannot slip up past the aluminum fastening strip. Odour is locked in and rain is locked out,” Mr. Larouche said.

In all, the installation of the cover system took only three days, and the entire project was completed in less than three weeks.

Effluent Reuse

Wastewater plant reuses two million US gallons of effluent per day

By Marcus N. Allhands 100 MGD Midwestern US wastewater treatment plant is now reusing up to 2 million US gallons of water per day.

Plants of this size need a lot of clean water for such applications as the automatic cleaning devices on the primary bar screens, spray bars on sludge belt presses and for pump seal lubrication.

Also, this plant generates its own electricity by using the methane produced in the anaerobic sludge digesters as fuel to power four large generators. The engines are cooled using cleaned effluent.

The consulting firm designing the expansion and upgrades to this plant decided on automatic self-cleaning filters with 150 micron stainless steel weavewire screens to make the effluent acceptable for reuse. Two 12 inch Orival Model OR-12-PS automatic self-cleaning filters were installed on a manifold, to operate in parallel to provide sufficient capacity in a small area. The type of filters utilized automatically clean themselves by backwashing a few distinct dime-size areas of the screen and then moving those areas over the entire screen surface. All of the screen area gets cleaned during each cycle, so the filters remain on-line during cleaning.

Upon initial start-up of this filtration system a number of problems arose. The large dual filter system began to experience clogged screens in a matter of minutes after start-up. When the filters were opened for inspection, the screens were found to be completely encased in a black stringy tarry thick sludge that even plugged the large holes in the coarse protective screen. Further investigation showed a thick layer of sludge had built up on the floor of the basin where the pumps supplying the filters drew effluent. Screen filters are not sludge filters, which is why they clogged.

An old coarse-screen continuous cleaning filter had been operating in this area for many years. But instead of flushing the debris it captured back to the

A

plant’s head-works, it dumped debris back into the basin. Decades of accumulated solids had built up inside this basin, forming the dense sludge layer encountered by the new filtration system.

All is now working well at the plant, with water reuse running at 800 -1000 gpm. The new filtration system is working appropriately and no nozzles have

plugged on the belt presses, nor have the generator engines overheated.

Effective Underground Storm Water Control,

In nature, rainfall is recognized as a life-giving asset.

When we develop a natural site the asset too often becomes a runoff liability for the developer and all parties downstream.

Traditional storm water ponds and infrastructure require expensive land area and are often over-taxed by runoff accumulations from many areas upstream.

Underground storm water detention, using economical corrugated steel pipe systems, permits developers to manage storm water on-site without sacrificing valuable land or flooding their neighbours.

For creative storm water management solutions contact a CSPI member in your neighbourhood.
