Comment by Tom and Steve Davey
The pipes, the pipes are still appalling - massive rehabilitation programs needed magine a gourmet restaurant where wonderful food is expertly prepared by skilled chefs in a spotless kitchen. Then consider an unlikely scenario where the same food is served from gleaming pots and pans on to chipped crockery to be eaten with corroded utensils. Unlikely? Perhaps. But this scenario could be applied to our drinking water distribution infrastructure. Not only are many water pipes and sewers badly in need of repair or renewal, but their leakage rate is quite as-
tounding to laymen. In 1997, ES&E reported on an Environment Canada survey that estimated that unaccounted-for water losses ranged from a low of 10 percent to a high of 35 percent. Astoundingly, some 12 years later, a new report, released in June 2009 by the Residential and Civil Construction Alliance of Ontario (RCCAO), states that municipal water systems in the province experience leakage rates ranging from 10 to 50 per cent. The report adds that “this massive leakage costs Ontario residents some
Letter to the Editor Dear Tom and Steve, In your May 2009 Editorial Comment, you've touched on a very important point. The quicker we act to minimize levels of lead in drinking water, the sooner public health will be better protected. This is especially important given the fact that infants and young children are particularly susceptible to adverse neurological effects from elevated levels. What makes the matter even more urgent is the fact that recent studies have suggested that no level of lead exposure is safe for children. It has been acknowledged that lead service lines provide the greatest potential for lead uptake. However, it is important not to ignore risks associated with solder and fixtures which contain lead. Lead solder can in fact be a very significant source when its corrosion leads to degradation, resulting in the release of particles which are then consumed. While lead service line replacement is desirable, replacing only the municipal portion has recently fallen out of favour. Some of the reasons are that lead uptake is not simply proportional to lead service length, and the proportion of customers that replace the section which they own is generally very low. The customer-owned portion (as well as lead solder) can still result in unsafe levels at the tap. Additionally, the partial service replacement process has been seen to actually increase lead levels for a period of time following the procedure. As a result, some jurisdictions have decided to replace the municipal portion only when the customer agrees to replace the private section as well. One important tool which your article did not address was adjusting water chemistry to make the water less corrosive. Often municipalities take a source water and make it more corrosive through their chemical treatment. It is interesting to note that under the Lead and Copper Rule in the US optimization of corrosion control is the first step to be taken when lead levels at the tap exceed the action level. Replacing the municipal portion of the lead service line is the next step to be taken if corrosion control does not bring concentrations below the action level. While implementing corrosion control will no doubt increase operating costs, there is doubt that the capital costs incurred in replacing only the municipal portion of a lead service line will result in optimized safety at the tap.

$700 million annually”. If the environmental costs are included, the price tag would be closer to $1 billion a year. (The full RCCAO study is available at www.rccao.ca) The lead author of the report, civil engineering professor Tamer El-Diraby of the University of Toronto, estimates that, if the work done in the province during the last 10 years had been completed a decade ago, taxpayers could have saved another $160 million. In addition, about 30 per cent of the energy used to pump water could be saved if leakage was addressed. That would amount to about $18 million in energy savings a year, and reduced energy usage would also contribute to a significant lowering of greenhouse gas emissions. The report notes a host of negative costs and impacts associated with leaky watermains, including: • Leakage can cause basement flooding, erosion of foundations, service disruptions, and, in extreme cases, sink holes. • Treated water contains chlorine and this may flow into sensitive water bodies. • Leaking sewer lines result in effluent being discharged into the environment. • There can be increased risks to human health. Another insane result is that leaked drinking water, which has been expensively treated to potable standards, may make its way to the sewage treatment plant, through leaky sewer pipes, where it has to be treated once more, this time as sewage. continued overleaf...

Comment by Tom and Steve Davey This report recommends that â€œseveral specific forms of deterioration or poor performance be quantitatively assessed and evaluated, including pipe deterioration, blockages and trapped air, pumping, and energy recovery.â€? Regarding the larger issue of sustainable infrastructure, the report recommends the following actions: 1. Reconfigure the methods used for evaluating return on investments in infrastructure projects to include more
quantitative analysis of sustainability impacts and benefits. 2. Establish long-term and clear policies for life cycle planning of infrastructure systems, including: improving data collection and analyses; incorporating energy-savvy design of utilities; broadening the objectives of the Green Energy and Green Economy Act, 2009 (GEA) to include urban utilities; creating a fund for expediting the renewal of energy-wasting facilities;
investigating new financing tools to help consumers, per the GEA; and, ramping up the use of advanced technologies. While potholes in roads and garbage piling up due to strikes cause public outrage and political action, neglected water and sewer pipes are out of sight and out of the public's mind. If the public could see what lies beneath the potholes, and what it is costing them, they would demand remedial action. The most cost-effective long-term way to ensure the integrity of our water is to embark on massive inspection and restoration of these water and sewerage systems, some of which are older than the humans they serve. While this will probably protect health more cost-effectively than many preventative medical programs, it will also provide thousands of skilled, highly paid jobs in engineering, construction and manufacturing. Such infrastructure rehabilitation will be good for our stagnant economy, our health and the environment. We have the inspection and remediation technology. What we really need now is the political will to make reducing watermain leakage a top priority. It will ultimately be a win-win situation for taxpayers and the environment.

Inserts can be installed in any catch basin drain or inlet.
In his article, “Next generation filtration systems take stormwater pollution prevention to a new level”, Andew Potter describes oil/grit separators (OGS) as being maintenance intensive, which results in them being “often overlooked” with regards to regular maintenance cycles. While this is very true in a lot of places, particularly on private sites, I believe the main reason OGS systems are not maintained, is due to a lack of regulation and enforcement. It is not due to the expense. And, if the owner is going to overlook a routine annual or semi-annual vacuum truck cleanout of their OGS system, how can one be sure that the same wouldnʼt be true for any catch basin technology, where many sites have to be serviced? I would also suspect that the maintenance cycles for point-of-source filtration systems are highly subjective to the site for which they are installed. For example, what happens in the fall when a slug of leaves gets in the catch basin after a wet weather event? Mr. Potter also talks about advances in filtration devices that eliminate clogging by such contaminants as petroleum and hydrocarbons, while at the same time being able to filter particles above 5 microns. I find it very hard to believe that if a filtration product, as a first line of defense, were at a gas station, or maintenance yard, and was subjected to a petroleum or oil spill, that the filtration media would not end up completely fouled. When you consider the different technologies available on the market for stormwater filtration, most require a treatment train approach to ensure the success of the filtration system by having OGS pretreatment before filtration. This ensures that the filters, particularly down-flow designs, are not subject to shock loadings of TSS or gross pollutants which can foul the media, rendering it useless or, at the very least, reducing its life expectancy drastically. To conclude, after all costs, particularly maintenance, are factored in, I believe that point-of-source filtration systems may not provide better overall value than an OGS. For example, one waste. remainIt has become clear that the rivers and ing pollution in most lakes, by stormstreams is primarily caused runoff. water runoff, especially urban snow During rainstorms and spring surfaces melts, built-up pollutants on into are washed away and deposited from catch basins.

OGS can often service a site where many filtration devices would have to be used to treat similar flow volumes. This is because filters have a low hydraulic capacity when compared to an OGS. Although filters provide better overall treatment when compared to an OGS, the difference in the level of treatment can cost exponentially more, maintenance not included. Dale Jackson, ACG Technology Dear Tom and Steve, Your Editorial Comment, “Should Toronto homeowners have to wait for lead-free drinking water?” which appeared in ES&Eʼs May 2009 issue, has been read with great interest. The Canadian Copper & Brass Development Association is the national trade association for the Canadian copper industry. We have a program to encourage the replacement of lead services across Canada and would like to make two important points. Firstly, the City of Toronto is going with partial replacement of lead services, to the property line. Scientific evidence indicates that this is the wrong approach. The City has rejected providing financial assistance for homeowners to replace their portion, but Ottawa and London, for example, are providing loans for such work. Further, the Ontario Ministry of the Environment encourages full service line replacement and coordination of the costs involved. Partial replacement makes no sense in our opinion. Secondly, lead-free alloys for fittings are now being specified by a rapidly growing list of municipalities across Canada. Stephen A.W. Knapp, Executive Director, Canadian Copper & Brass Development Association Dear Tom It was great to open my May 2009 edition of Environmental Science & Engineering and see the reigns being passed on to competent people. You have trained Steve and Penny well, and can be proud of their desire to carry on. Stanley J. Mason, Terminal City, Vancouver, BC

New facility in Hamilton to generate electricity By Wilson Nolan, Mike Thomson and Jennifer Ahluwalia from biosolids n a climate of heightened environmental awareness, both globally and locally, which is increasing pressure for waste diversion from landfill, greenhouse gas (GHG) cap-andtrade schemes, and new legislation to support renewable electricity generation, many jurisdictions are re-evaluating their biosolids management strategies. Developing the green economy is a priority of the current government in Ontario and new developments are occurring rapidly. One of the challenges is creating initiatives, policy and legislation that address issues of waste management, energy use, efficiency, and public health in a way that supports the common goals. There is an inextricable link between GHG reductions and low carbon electricity generation, as well as energy efficiency. Waste management provides an excellent opportunity to improve the efficiency of resource use through the beneficial use of by-products. Significant quantities of biosolids are generated in Ontario. The Biosolids Utilization Committee (BUC) estimates that 200 wastewater treatment plants generate approximately 300,000 tonnes (dry weight) of biosolids in Ontario per year (Meerveld, 2007). Three pulp and paper mills in Southern Ontario generate approximately 150,000 tonnes (dry weight) of biosolids per year, of which nearly 100,000 tonnes were land-applied in 2007 according to BUC (Meerveld, 2007). In Ontario, there are three main management alternatives for biosolids: landfilling, agricultural land application as a source of nutrients and soil amendment, and treatment using thermal technology. Pressure to divert organic waste from landfills takes different forms in each jurisdiction. In Ontario, the diversion goal is currently set at 60%, to be achieved through diversion of both organics and recyclables. In the European Union, the diversion goal of the â€œLandfill Directiveâ€? is only concerned with biodegradable waste with reduction targets of 25%, increasing to 65% in 2020 (EU, 1999). A report from the European Environ-

mental Agency published in June 2009 provides a summary of legislation and public policy from a number of jurisdictions in Europe, used to encourage preferred management solutions. Germany uses one of the most aggressive policy instruments of the nations and regions that the EEA reported upon, where the total organic content of waste sent to landfill must be less than 3%. In the context of biosolids management, setting the threshold so low guarantees diversion or further processing prior to landfilling. Under this scheme, thermal technologies are attractive because of the potential for energy recovery and the ability to deliver a by-product (fly ash) that is low volume and has a low organic content for recycling or landfilling. The risks of pathogen and pollutant release from landfilling have decreased with recent improvements in landfill lining technology. Gas collection systems are typically installed within the landfill to collect methane which can be sold as a commodity or used in an integrated cogeneration system (i.e., to generate electricity and low-grade heat). The collection and utilization of landfill gas is becoming more popular and in some jurisdictions it is mandatory. However, landfill capacity is limited and many jurisdictions have established policies limiting landfill receipts.
Ontarioâ€™s requirement for municipalities to achieve 60% diversion of wastes suggests that landfilling of organics is not a viable long-term solution. Source water protection has resulted in a re-evaluation of the potential for environmental impacts from the presence of heavy metals and trace organic compounds found in biosolids. Land application is seasonal and weather-dependent, with nine months of storage now required in Ontario. There are a variety of thermal treatment technologies, including: fixed hearth, multiple hearth, rotary kilns and fluidized bed reactors. Fluidized bed technology provides the advantage of flexibility with respect to the variability of the fuel and is currently the most widely applied (Figure 1). Biosolids are typically dewatered by centrifuges or belt filter presses before being fed to a reactor at approximately 26-30% dry solids (Welp and Partington, 2008). Following combustion in the fluid bed, exhaust gases are directed to a series of air pollution controls (e.g., wet scrubbers, separators). Treated exhaust is emitted through a stack, while ash is collected from the separator and recycled or disposed off-site. To facilitate progress toward GHG reduction commitments, and to increase the amount of energy produced from re-

Biosolids Management newable sources and foster a green economy, the Green Energy Act (GEA) was introduced and passed the Ontario legislature on May 14, 2009. This legislation has a number of key elements, many of which have the potential to affect biosolids management, particularly solutions that include energy recovery for the purpose of electricity generation. Proposed regulations under the Act will provide a new framework to streamline the approvals process for renewable energy projects and a feed-in-tariff system to provide guaranteed pricing for electricity exported to the grid at a tariff that makes economic sense. Supporting environmental initiatives is a priority for most biosolids managers but, until GHG offsets have real monetary value, it can be challenging to justify changing management practices from the status quo. The Greater Vancouver Regional District used life cycle analysis to determine whether landfilling with gas recovery, anaerobic digestion with land application, or incineration with energy recovery was the best solution for their biosolids. All processes downstream of sludge
thickening in wastewater treatment plants were included. Thermal treatment with energy recovery (electrical generation) was found to have the lowest cost on a life cycle basis (GVRD, 2005) It should be noted that life cycle analysis is case-specific and cannot be generalized to all situations. For example, in Vancouverâ€™s case study, transportation reduction provided significant cost savings due to the proposed colocation of the thermal facility with wastewater treatment facilities. However, even without including transportation, incineration with energy recovery was still the least costly solution. It is likely that many of the same assumptions would apply to equally large urban areas in Ontario, especially with the higher electricity prices proposed as a feed-in-tariff system under the GEA ($0.138/kWh for biomass vs. $0.07/kWh used in GVRD study). Thermal treatment with energy recovery A thermal treatment facility poised to generate green electricity has already been approved for the City of Hamilton. The Liberty Energy Centre (LEC) may
serve as the pioneering example for the biosolids-to-energy facilities of the future. The LEC will take advantage of fluidized bed gasification technology to use biosolids as fuel from various sources, and will be capable of using digested and undigested biosolids co-fired with biomass as a second fuel. Biomass used in the process will include leaf and yard waste, arbour waste and clean dimensional lumber scraps. LEC has the potential to play a major role in the phytosanitary management of Emerald Ash Borer infested trees as nearly 100 percent mortality is expected in the next 10 to 15 years. Under normal operating conditions, the LEC will be capable of processing up to 272 dry tonnes of biosolids and 292 dry tonnes of biomass per day. When operating at capacity the facility will have the potential to convert nearly one third of the biosolids produced by Ontario municipal wastewater treatment plants into renewable energy. Reliability of biosolids handling/disposal is critical for municipal facilities that must operate continuously. The continued overleaf...

LEC design incorporates redundancies throughout the process, including duplicate identical process trains, each with its own fluidized bed reactor, and duplicate sets of biosolid/biomass handling and storage equipment. This means that the facility can continue to accept and process biosolids throughout maintenance and upset activities. For a facility to qualify as generating renewable electricity, it must derive 95% of its energy from renewable sources. Biomass is listed under the definition of “renewable energy sources” in the GEA. Both biosolids and biomass from urban sources are included in the definition of biomass in the draft Feed-In-Tariff (FIT) program rules under the GEA. The FIT program provides a reliable mechanism to sell renewable power to the grid under a 20-year agreement which is common in the EU but new to North America. The energy of combustion from the
the Ontario Power Authority’s Renewable Energy Standard Offer Program (RESOP). Electricity from Unit 2 is expected to receive guaranteed pricing under the new FIT program that replaced RESOP under the GEA. The push for renewable energy is at least partially driven by GHG reduction commitments. As a partner in the Western Climate Initiative (WCI) it is likely that Ontario will formalize a GHG capand-trade system through legislation in the near future. The WCI’s plan is set for implementation in 2012 when the capped system will take effect for partner provinces and states. The Ontario government has already set its own reduction targets based on 1990 emission levels. The targets were set at a reduction of 6% by 2014, 15% by 2020, and 80% by 2050 (Ontario, 2009). The proposed cap-and-trade system targets industries with historically

high carbon emissions such as electricity generation and primary resource development. The major contributors to GHG emissions from our current electrical energy mix are coal, refined petroleum products
(i.e., heavy fuel oils and diesel) and natural gas-fired stations which require approximately 1000 gCO2e/kWh, 800 gCO2e/kWh, and 400 gCO2e/kWh respectively (Environment Canada, 2005). Biosolids management could enter the electricity market as a method of offsetting emissions through renewable electricity production that is near carbon neutral. Transportation of biosolids provides another opportunity for offsetting GHG emissions if the distances travelled can be decreased. In urban settings such as the Golden Horseshoe in Ontario, landfills and appropriate areas for land application are often far from wastewater treatment facilities, while the proposed location of the LEC is within the industrial zone of the City of Hamilton. Although GHG emission and renewable energy are highly publicized, they are not the only environmental concern for the thermal treatment of biosolids. Liberty received the support of well-informed public interest groups in Hamilton with its extensive air pollution control technology and commitment to odour management. Another part of Liberty's success in gaining public favour was their ability to communicate the technical aspects of their project (see Figure 2). The odour management plan for the facility includes sealed storage of biosolids and indoor receiving of both biosolids and biomass, with all venting to either the gasifier or a biofilter. The air pollution control technology that will treat the exhaust from the gasifier includes: selective catalytic and non-catalytic reduction technology, lime slurry wet scrubbers, fabric filters, and powdered activated carbon (PAC) scrubbers. The LEC in Hamilton is one of three projects that Liberty Energy is proposing for the thermal treatment of biosolids. The other two projects are located in California. The proposed facility in Hamilton has progressed farthest through the permitting process and is set to break ground in 2010.

120 days for fair trade deal - FCM t their annual conference in June, members of the Federation of Canadian Municipalities (FCM) voted to adopt a fair trade resolution, in response to the US’s increasingly protectionist actions. One key item of the resolution is that FCM supports municipalities who choose to adopt procurement policies which favour free and fair trade by ensuring that local infrastructure projects, including environmental projects such as water and wastewater treatment projects, procure goods and materials required for the projects only from companies whose countries of origin do not impose trade restrictions against goods and materials manufactured in Canada. In an address to conference delegates, Jean Perrault, FCM President and Mayor of Sherbrooke, spoke on the resolution. The following is an excerpt of his presentation: "Canada´s cities and communities joined the federal and provincial gov-

ernments in a common front to try and stop American protectionism. We stand united in the belief that fair trade and an even playing field are in the best interest of our country, our communities and our citizens. By supporting the resolution brought forward by the Town of Halton Hills, Ontario, our members have strengthened Canada’s bargaining position. By holding back from endorsing countervailing procurement measures for 120 days, we recognized the Prime Minister’s commitment to finding a solution to this issue. “The timeframe of 120 days will give the Canadian and US governments some breathing room. At the same time, it will continue to shine a light on this issue and ensure that everyone’s energies remain focussed on finding a quick resolution. This US protectionist policy is hurting Canadian firms, costing Canadians jobs and damaging Canadian efforts to grow our economy in the midst of a worldwide recession.
“It was municipalities that pushed this issue to the top of the national agenda. We did it by pointing to the damage that protectionism can do, not just to trading relations, but to communities and their residents. “The government’s decision to urgently seek a bilateral deal was the right thing to do. Over the next 120 days we will support the government´s efforts and have offered to assist by providing expertise on local procurement and making the case to our municipal counterparts in the United States. “We are prepared to work closely with Minister Day and the provinces to push for fair trade between our two countries and a deal that protects jobs and the interests of our communities and their residents. A solution is urgently needed. Jobs are on the line.” For more information visit, www. fcm.org.

Small footprint technologies combine for high-rate wastewater plant efficiency By R. Lafond, H. Halaweh, C. Scott and R. Niechcial tricter treatment and discharge regulations are forcing wastewater treatment plants in urban and high-growth areas to consider expanding or upgrading their systems. Even if extra land is available, it is often not economically feasible to use this. Fortunately, certain small-footprint technologies now provide efficient high-rate wastewater treatment. For example, the compact moving bed biofilm reactor (MBBR) process, coupled with a unique sand-ballasted clarification and flocculation water treatment system, will yield a very flexible wastewater treatment plant in just a fraction of the space required by conventional treatment technologies.
Figure 1. Skreia WWTP in Norway.
Wastewater treatment using biofilm processing has become popular in recent years. One method, the AnoxKaldnesTM MBBR technology, is a continuously operating, fully biological treatment process based on biofilm processing. The processes use plastic media to grow the biofilm, which is retained in reactors using media retention sieves while an aeration system allows the bacteria/biofilm to provide the treatment required. Effective biomass within the bioreactor is augmented through growth on the media, and nearly all of the biomass is resident on the media. The carrier elements provide a large protected surface area for the biofilm as well as optimal conditions for the bacteria culture to grow and thrive in the rewww.esemag.com

Because the biofilm created around each carrier element provides a more stable environment for the bacteria to grow, less footprint space is required. The MBBR biofilm carriers are sus-
pended and thoroughly mixed throughout the water phase where they move freely in the tanks. Excess biofilm is continuously sloughed from the media and carried out with the effluent. In addition to increasing treatment capacity, the MBBR system has demonstrated ef-

quirements of traditional flocculation/sedimentation systems. These systems are typically one-fifth to 1/20th the size of conventional clarification systems offering similar capacity. In the sand-ballasted flocculation process, raw water is first mixed with a coagulant in a high-shear environment. In the next tank, the water is injected with a polymer and microsand and mixed aggressively before it enters the “maturation zone,” where gentle shear is applied. The microsand-ballasted flocs increase in size, trapping smaller flocs before the water enters the sedimentation tank, where the large flocs immediately begin to settle. At this stage, the clarified water then flows upward through lamellar settling tubes to collection troughs where it can be diverted to various applications. The microsand and other solids in the ballasted flocs that settled in the bottom of the tank are then pumped to a hydrocyclone, where the microsand is cleaned and reinjected for reuse and the waste solids are removed. The technology has proven both flexible and versatile. The coagulation phase works on total suspended solids as well as on chemically active contaminants. The polymer flocculent ensures that the microsand bonds strongly to the flocculated solids. The flocs, by themselves, are typically at or near the density of water, so they cannot settle rapidly without the added weight of the microsand (specific gravity of 2.65). Once ballasted with the tiny microsand particles, the flocs sink immediately in the settling tank. ACTIFLO is a multi-task technology,

Wastewater Treatment serving as an effective high-rate clarifier and a versatile chemical reaction vessel. Depending on pH conditions, colloidal and particulate pollutants in the influent can be precipitated using classic chemical methods for efficient, sand-ballasted removal in the settling step. Virtually any constituent of raw feed water or wastewater that can be coagulated through physico-chemical means can be effectively processed through the system. Combining high-rate technologies Limited space for wastewater treatment plant expansion is an ongoing challenge for urban areas or constrained peri urban installations. Being able to combine two high-rate wastewater treatment technologies would prove a major benefit for municipal decision-makers. Two municipal plants in Norway are leading by example. Water treatment officials in Skreia wanted to upgrade its 20year-old conventional activated sludge treatment plant to increase capacity by 80% to manage an increasing load from a local potato processor. However, the plant is situated close to Lake Mjosa and the area available for facility expansion was restricted by farmland and a wildlife reserve. Hence, it was necessary to look for a compact treatment solution that could be easily retrofitted with the existing plant. The integration of AnoxKaldnes MBBR and ACTIFLO technologies into the existing Skreia WWTP (Figure 1) allows for wide variations in both hydraulic and organic loads. The MBBR technology was chosen for high-rate biological treatment, to remove soluble organic matter and to increase and enhance the biological treatment capacity. Effluent from the MBBR treatment is then routed to the ACTIFLO unit for final sludge separation and high quality effluent discharge. The plant also has the option of routing MBBR effluent to the plantâ€™s settling tank.
Limited space for wastewater treatment plant expansion is an ongoing challenge for urban areas or constrained peri urban installations. Using the two high-rate, small-footprint technologies has resulted in excellent removal efficiencies, and the expanded plant conforms well to the space limitations presented by the site. The rural area of Handeland, also in Norway, has a small residential population but increasing seasonal tourist activity. The municipality expects even further significant tourist growth in the near future. To meet the challenge, the municipality chose to build a new treatment plant to serve the entire community. The new wastewater treatment plant consists of screening, an MBBR for biological wastewater treatment and the high-rate sandballasted clarification and flocculation technology for sludge separation. The new plant is meeting the needs, requirements and expectations of the municipality (Figure 2). The treatment units consist of two interchangeable trains, providing operational flexibility in handling large variations in flow and load. R. Lafond, H. Halaweh, C. Scott and R.

Sludge & Dewatering
A dewatering technology for lagoon sludge management agoons have long been used for the treatment of liquid waste sludge. While they are an effective means of treating and storing sludge, lagoons often produce unpleasant odours and, if not properly maintained, can lead to environmental concerns. Regular maintenance and upkeep are essential to keeping lagoons operating properly, and to protecting the health of humans and the environment. Despite regular weekly and monthly maintenance, however, lagoons eventually become filled with sludge and must be cleaned in order to allow them to continue operating, or in some cases to allow for their closure. Many municipalities and industries around the world have chosen the Geotube速 dewatering technology as an economical and effective method for lagoon cleanouts. Lagoons containing pulp and paper sludge, agriculture waste, sewage sludge, tailings from mining operations, processing waste from food production

and a host of other waste streams have all been dewatered using this technology. Geotube dewatering units are geo-synthetic containers made from high-tensile woven polypropylene. The technology works by allowing sludge to be filtered through the dual filament polypropylene fabric, while retaining a high percent of solids. As sludge is pumped into a unit, it is injected with a polymer. The addition
of the polymer to the sludge is necessary to flocculate the sludge and allow the technology to dewater as effectively as possible. The technology offers many benefits. The containers provide not only effective dewatering, but also on-site storage capacity. This allows for the cost of the lagoon cleanout to be spread out over time. A lagoon can be dredged in year one and

Summer09:Layout 1 21/07/09 7:16 PM Page 21
Sludge & Dewatering the units can be left to dewater on-site until the following year, at which point the bags can be opened and the retained solids disposed of. The ability to dewater and contain sludge in one process allows for minimum capital expense. When utilizing this technology, the volume to be removed is based on the volume of sludge in the lagoon, and the percentage solids of the sludge. Based on these parameters, a volume of bonedry tons is calculated for removal. The client does not pay for the removal of liquids, only solids. Odour reduction Often lagoon sites are plagued with odour issues, which can cause public backlash and the demand for change to current operations. Lagoon cleanouts utilizing Geotube dewatering containers are done simply and quickly. In many cases the cleanout takes only days. The units sit on a temporary dewatering cell constructed of crushed stone, a geomembrane liner and a non-woven geosynthetic material. The dewatering cell is typically situated around the parameter of the lagoon, sloped so that the effluent is directed
back into the lagoon by gravity. If available space is an issue at a particular site, the dewatering cell can be constructed with a catch basin at one end of the dewatering cell. As the units drain into the basin, the clear effluent is pumped back to the lagoon. A dredge is used to blend the sludge in the lagoon and transfer it to the Geotube units. As the sludge is pumped from the lagoon, it passes through a mobile PVC mixing chamber where it is injected inline with polymer to flocculate the sludge. Once the units begin to fill, clear filtrate immediately begins to filter through the bag, while the solids are retained inside. Due to the high retention of solids, the cost of disposal is greatly reduced. In addition, the waste to be disposed of is no longer in liquid form, but a solid cake, which is important as the public perception of the land application and landfilling of liquid wastes is becoming more negative every day. The same technology can be used by municipalities and industries that currently operate lagoons as a means of sludge management by removing the solids from the waste stream prior to
being deposited in the lagoon. This process is simple. Sludge that would previously have been disposed of in a lagoon system is transferred instead to an underground holding tank. Once the tank has filled with sludge, it is batch-entered into the Geotube units, and the effluent is directed to the lagoon. The solids are contained in the dewatering containers, never reaching the lagoon. Dewatering sludge before it is deposited in a lagoon system removes odours, reduces the size of the system required and, most important, eliminates the need to clean the lagoon and dispose of sludge. Instead of dumping sludge into the lagoon system, the system will be filled with a clear effluent. Every lagoon cleanout is unique, with each presenting a different set of challenges. Lowering transportation costs, on-site storage, reducing odour, retaining valuable solids, quick mobilization and meeting stringent environmental protocols are just a few.

CO2 neutral seawater desalination By Nikolay Voutchkov ver the past five years, desalination has gained significant momentum in California. With more than 10 projects in various stages of environmental review, design and construction, desalination is planned to provide 1,500 to 2,000 million litres per day (ML/d) of new fresh drinking water supplies for the state by 2015. One of the largest and most advanced projects under development today is the 189-ML/d Carlsbad seawater desalination plant (Figure 1). This project is colocated with the Encina coastal power generation station, which currently uses seawater from the Pacific Ocean for once-through cooling. The Carlsbad seawater desalination project is being developed as a public-private partnership between the project proponent, Poseidon Resources, and eight local utilities and municipalities. The Carlsbad project received the â€œgreen lightâ€? from all regulatory agencies in California in August 2008, and construction is planned to begin in the fall of 2009. When completed in 2012, this project will supply 6-8% of the drinking water in San Diego County and will be the largest seawater desalination plant in the United States.
Figure 1. Carlsbad seawater desalination plant.
In 2006, California legislation introduced the AB 32 Global Warming Solutions Act, which aims to reduce the stateâ€™s greenhouse gas (GHG) emissions to 1990 levels by 2020. In response to this initiative, the project proponent has committed to mitigating the carbon footprint associated with the desalination plant opera-

tions. When constructed, this will be the first desalination project in the US that will have a zero net carbon footprint. Carbon footprint of desalination The total plant carbon footprint of a desalination plant depends on two key factors: how much electricity is used by the plant, and what sources (fossil fuels, wind, sunlight, etc.) are used to generate the electricity supplied to the plant. The total carbon footprint for the Carlsbad project is estimated at 61,000 metric tons of CO2/yr and is based on desalination plant power use of 3.57 KWh/m3 of produced drinking water and on a GHG emission factor of 248.4 kg of CO2 per MWh of electricity used for the project. Currently, San Diego County imports 90% of its water from the distant (over 800 km) Sacramento Bay Delta and Colorado River via a complex system. The amount of electricity needed to deliver and treat this water is 2.748 KWh/m3. Since the desalination project will eliminate the need to import 189 ML/d of water, this will save 189,800 MWh/yr, or 47,240 metric tons CO2/yr of GHG emissions, from the energy used to pump this water to the county. Thus it is estimated that the Carlsbad desalination

Summer09:Layout 1 21/07/09 7:16 PM Page 23
Drinking Water plant’s net carbon footprint will be reduced from 61,000 to 13,760 metric tons of CO2/yr. The Carlsbad project aims to eliminate the plant’s net carbon footprint altogether by a balanced combination of energy-efficient design and operations, green building design, use of carbon dioxide for water production, on-site solar power generation, carbon dioxide sequestration by creation of coastal wetlands and reforestation, funding renewable power generation projects, and acquisition of renewable energy credits. The desalination plant will reuse energy from the seawater concentrate generated in the salt separation process by a state-of-the-art energy recovery and reuse system (Figure 2). After membrane separation, most of the energy applied for desalination is retained in the concentrated stream (brine) that also contains the salts removed from the seawater. This energy-bearing stream (shown with red arrows in Figure 2) is applied to the backside of pistons of cylindrical isobaric chambers, also known as pressure exchangers (shown as yellow cylinders). These pistons pump approximately 45-50% of the seawater fed into the reverse osmosis membranes for desalination. An average of 5% of additional energy savings and respective carbon footprint reduction (12,308 MWh/yr and 3,057 tons/CO2 per year) are projected to be achieved by using warm cooling water from the Encina Power Generation Station as source seawater rather than collecting cold ambient seawater via a separate ocean intake. The osmotic pressure that has to be overcome during the salt separation process decreases with the increase in seawater temperature. Since the power plant discharge is approximately 5°C warmer than the ambient seawater, the innovative colocation technology used for the Carlsbad project will yield both energy and GHG reduction savings. Green building design The plant will be located on a site currently occupied by a dilapidated fuel oil storage tank. Reclaiming the land will produce a smaller imprint on the environment than if an undisturbed site were used for the desalination plant. A key “green” feature of the plant design is its compactness. Sharing comwww.esemag.com
mon walls, roofs and equipment will allow significant reduction of its physical footprint. The total area occupied by the plant facilities will be less than five acres. When built, this will be the smallest-footprint desalination plant in the world per unit production capacity. The building’s design will follow the principles of the Leadership in Energy and Environmental Design (LEED) program, which aims to reduce the overall impact on the environment of building construction and functions. Minimizing
energy use for lighting, air conditioning and ventilation will be achieved, for example, by translucent panels to maximize daylight use and views to the outside, automatic light switching, monitored ventilation in individual working areas and water-conserving fixtures for service facilities and landscape irrigation. The energy savings associated with the implementation of the green building design are in the range of 300-500 MWh/yr. The carbon footprint reduction
Summer 2009 | 23
Summer09:Layout 1 21/07/09 7:16 PM Page 24
Drinking Water associated with this design is between 75 and 124 tons of CO2 per year. One enhancement of the green building design is the installation of a rooftop photovoltaic system for solar power generation (Figure 3). The main desalination plant building will have a roof surface of approximately 50,000 square feet, which is adequate to house a solar panel system that can generate approximately 777 MWh/yr of electricity and reduce the net carbon footprint of the desalination plant by 193 metric tons of CO2 per year. Use of carbon dioxide Approximately 2,100 tons of CO2 per year are planned to be used at the desalination plant for final conditioning of the fresh water for corrosion protection. The drinking water ion balance (pH) will be maintained in a range of 8.3 - 8.5 that allows the CO2 to remain sequestered with the drinking water. The plant is planned to use only CO2 collected from industrial operations that generate this gas as a waste stream (breweries, ethanol plants, etc.), which otherwise would be released in the air. Other environmental initiatives Almost every year, parts of San Diego County experience large wildfires. For example, in 2007, San Diego wildfires burned over 35,000 acres, including forests, tree farms and urban forestry. In response to an ongoing wildfire zone revegetation program spearheaded by the California Coastal Commission, Poseidon Resources has committed to invest US$1 million in reforestation activities.

Figure 3. Solar panel rooftop system.
Total annual carbon footprint reduction associated with the tree sequestration project is estimated at 166 metric tons of CO2 per year. As a part of the Carlsbad project, Poseidon is planning to develop 37 acres of new coastal wetlands in San Diego County. These wetlands will be designed to create habitat for marine species similar to these found in the Agua Hedionda Lagoon (Figure 1), from which source seawater is collected for the power plant and desalination plant operations.
In addition to the benefits of marine habitat restoration and enhancement, coastal wetlands also act as a carbon dioxide “sink.” Tidal wetlands are very productive habitats that remove significant amounts of carbon from the atmosphere, a large portion of which is stored in the wetland soils. While fresh-water wetlands also sequester CO2, they are often a measurable source of methane emissions. By comparison, coastal wetlands and salt marshes release negligible amounts of greenhouse gases, so their carbon sequestration capacity is not measurably reduced by methane production. The offset of the desalination plant carbon footprint by the wetland project is estimated at 304 tons of CO2 per year. For the remainder of the project’s GHG emissions, Poseidon will purchase a combination of carbon offset projects and Renewable Energy Credits (RECs). Contracts for offset projects provide more price stability and are typically established for longer terms (10 - 20 years) than RECs (1 - 3 years). Offsets or RECs will be used as the swing mitigation option to “true-up” annual changes to the project’s net carbon footprint. The GHG reduction plan for the Carlsbad project defines a roadmap for carbon-neutral seawater desalination for future projects in the US and worldwide.

Managing runoff in Surf City USA By David Scott untington Beach is the prototypical oceanside community depicted in the hundreds of sitcoms, movies and Beach Boys songs that California has exported to Canada and the rest of the world over the past five decades. The city, located 20 miles south of Los Angeles, has even trademarked itself as â€œSurf City USA.â€? Across town, the operators of the Good Shepherd Cemetery focus less on the surf and more on containing and managing the water that runs across their land. The owner, the Diocese of Orange, is expanding the century-old Catholic burial ground. But before the expansion could take place, the Diocese had to prepare a stormwater management plan for the site. The area has faced issues with flooding over the years, with nearby roads and yards puddling up during heavy rains that overwhelmed local drains. The water management plan will eventually include a new public drainage system to control the runoff flowing through, as well as additional runoff emanating from the cemetery site. Along with controlling the runoff from the site, the owners needed to create a system to treat the runoff. California had instituted new rules governing the installation of filtration systems in new projects, so the diocese had to set up systems to remove a variety of pollutants, including metals, bacteria and oils. California is one of several US states to take a lead role in requiring the use of filtration systems to aggressively treat stormwater for harmful pollutants and nutrients that can damage the ecosystem.

number of solutions, including a requirement to conduct site-level filtration of pollutants before they enter the lake. Choosing a filtration system The first phase of the California project was completed in late 2008.
While the stormwater treatment system chosen for the site needed to perform to specifications, the owner and contractor had made cost savings a priority in the selection process. After the City of Huntington Beach initially approved a plan that included a radial cartridge filter, Truxaw & Associates Inc., of Orange, California, the engineering firm overseeing work on the project, convinced the city to consider an alternative, more cost-effective solution, the Up-FloÂŽ Filter, designed by Hydro International and supplied locally by Kristar Enterprises. The Up-Flo Filter, based on upflow filtration technology developed at the University of Alabama, incorporates multiple elements of a treatment train

Stormwater Management — screening, sedimentation and highrate filtration — in a compact modular device. It offers cost savings, made possible by its high treatment efficiency in a small footprint. The Up-Flo Filter uses a sedimentation sump and screening system to pretreat stormwater runoff before it flows up through the filter media where final filtration occurs. A high-capacity siphoning bypass safeguards against upstream ponding or flooding during high-flow events. The siphon also serves as a floatables baffle to prevent the escape of floatable trash. Upflow technology sends flow in an upward direction, countering gravitational forces to fluidize the media and allow the entire depth of the media bed to be utilized. This results in extended run times before clogging. The first unit consisted of two structures, with treatment being conducted in one and water being bypassed into a second unit. The Up-Flo Filter combines these processes into one unit. The differences in design between the first specified unit and the Up-Flo Filter
helped to sell both the engineer and Huntington Beach environmental officials on its long-term benefits.
Inside view of the Up-Flo Filter.
California regulations require stormwater to be treated on the first flush, removing up to 80% of all total suspended
solids. Independent laboratory tests from a variety of sources, including the New Jersey Corporation for Advanced Technology, have verified the Up-Flo Filter’s ability to remove pollutants under a variety of conditions. Van Diest Brothers Construction, the site contractors, installed the first filter during the initial phase of construction. Two or more systems are planned in the second and third phases, which are expected to be undertaken sometime in the next decade. The Up-Flo Filter is one of several stormwater treatment products offered by Hydro International. The Downstream Defender, another vortex separator, has been used successfully in a large number of applications in Canada for the removal of sediment, oil and floatables from stormwater runoff.

Pollutant release: A ‘dirty secret’ in stormwater treatment atch-and-release may be a sound concept in fishing, but catching pollutants in stormwater runoff and releasing them later during large storms is obviously a problem. Yet many stormwater treatment systems do just that; they capture pollutants over time, only to release them back into the environment when the system becomes overwhelmed during high-intensity storms. Communities across Canada have made significant investments in improving water quality. Are we getting the best return on our investments? How effective are most manufactured stormwater treatment systems? And what can be done to ensure that the best systems are being installed? During typical storms, water and sediment flow into the chamber of a stormwater treatment system. Oil rises and sediment settles typically under calm conditions. According to Stoke’s Law, the smaller the particle size of the sediment, the more time is required for it to settle. The primary focus to date in stormwater treatment has been on removing total suspended solids (TSS), which include smaller sediment particles (clay and silt-sized) as well as larger sediment particles (sand and gravel-sized). Many urban pollutants attach themselves to TSS, including hydrocarbon oil, heavy metals and nutrients. It is the smaller particles, with their dramatically larger surface area for a given mass, that absorb the majority of the pollutants. Most stormwater treatment devices or oil and grit separators receive runoff from parking lots or roads. The fine particles that are captured contain brake pad dust, tire wear fragments and motor oil. It is crucial for this black, tar-like, pollutant-laden sediment to settle and remain contained inside the treatment units until it is physically removed during the units’ next maintenance event. How pollutants are released Small storms make up most of the annual volume of runoff and, therefore, typically represent the majority of pollutants coming off an urban site. During these smaller storms, the runoff rates are lower and, in a properly-designed treatment system, sediment and free oil are removed, including the higher pollutant-laden clay and silt-sized particles.
It is crucial for this black, tar-like, pollutant-laden sediment to settle and remain contained inside the treatment units until it is physically removed during the units’ next maintenance event. Larger, high-intensity storms represent a much smaller portion of annual runoff but present the challenge of much higher runoff rates. The main focus during an intense storm, from a treatment standpoint, is to protect the TSS and pollutants that were previously captured.

lutants, re-suspending them in the runoff and consequently sending them downstream to our precious water bodies. While much effort has been devoted to designing systems to minimize pollutant release, other inadequately designed devices are very much at risk of re-suspending and releasing previously captured sediment and pollutants when a high-intensity storm occurs. Surprisingly, while most stormwater treatment devices are required to be rigorously tested by numerous agencies to verify pollutant capture rates, the attention given to re-suspension and release has been minimal. The few re-suspension tests that have been completed to date focused mainly on larger particle sizes. In reality, it is the smaller particles (clay and silt) that contain most of the pollutants and are more susceptible to re-suspension and release. The vast majority of pollutant removal testing is conducted on “clean” units. While this makes it easier to measure what was removed initially from runoff water, in real life these units almost always contain previously captured solids and sediment that have built up during previous rain events. One North American agency has recognized this gap in testing methodology and sees pollutant release as a real threat to water quality. The New Jersey Department of Environmental Protection (NJDEP), which has overseen the Technology Acceptance and Reciprocity Partnership Program for stormwater, has begun working on a new re-suspension testing protocol. This protocol needs to be stringent and include fine particles if the industry’s “dirty” little secret is going to be dealt with properly. The NJDEP has also recently implemented a policy requiring all in-field installations to ensure that urban runoff during large storm events will completely bypass the treatment chamber of the device. A set of rigorous re-suspension studies was recently completed by the University of Florida’s (UF) Department of Environmental Engineering Sciences. UF has been actively Environmental Science & Engineering Magazine

Stormwater Research studying the area of re-suspension and has tested two fullscale, manufactured stormwater treatment systems that were pre-loaded with a buildup of sediment in order to replicate the typical conditions in the field. The contrasting results of the two studies clearly highlight that pollutant re-suspension and release occurs without proper flow control technology and bypass functionality. The “Big Three” guidelines The design of a manufactured stormwater treatment system is key in preventing pollutant release. Following are three core guidelines for specifying a re-suspension proof system: 1. Choose a device designed to minimize re-suspension. Several systems incorporate specific design features that reduce pollutant release. In a properly designed treatment device, the incoming runoff velocity and force is significantly weakened and reduced in order to avoid stirring up settled sediment and re-suspending the pollutants. Ensure the manufacturer can back up its claims with third-party studies. 2. Size the device properly. The sizing methodology of a system should be based on supportive testing, to determine the depth and diameter necessary to ensure the correct hydraulic loading rate for the site conditions. There are also advantages to systems that offer highly developed sizing software, with the option to input site parameters including particle size distribution. 3. Maintain the device properly. All stormwater devices require maintenance. Regular maintenance is critical to overall performance. Too often, this is neglected, compounding the pollutant release issue. This is perhaps the biggest “dirty”

little secret of all in the industry. Units are specified, installed and then forgotten, often for years. The problem is noticed only when water quality objectives are not met, or when dramatic environmental damage has occurred. We should all be pushing to highlight the importance of proper ongoing maintenance. Like many of the environmental dilemmas facing Canada, combating stormwater pollution requires both ingenuity and commitment. The guidelines listed above, when combined with knowledge of individual site conditions and the regional environment, can help to ensure that the best system is implemented to protect the environment and meet water quality objectives.

How wireless remote monitoring enables low-cost By Barb Smith data logging and control eeting the requirements for monitoring of mobile assets and remote processes economically always presents project engineers with a considerable challenge. For example, monitoring of combined sewage overflow by water utilities meets a regulatory requirement. Compliance with mandates from agencies such as the United States EPA calls for monitoring of remote locations in which only a single measurement, flow or level, is taken per site. Monitoring of vendor-managed inventory, such as a chemical level in a tank, is an economically driven example. Again, only a single measurement, tank level or pressure, is required. Economic goals include customer satisfaction and operation of the delivery/service fleet in the most efficient manner. Leased generators and pumps exemplify mobile assets in which, at minimum, one or two measurements are recorded. In those cases, however, requirements could grow to dozens of measurements. Customer satisfaction and optimal management and maintenance of the asset inventory are the goals. Basic monitoring requirements As the project begins with reasonably simple goals, basic requirements for a remote monitoring device are established: • Monitoring of discrete inputs such as float switches, on/off status, contacts on doors, entryways. • Monitoring of a primary process measurement such as flow, liquid level, pressure or temperature. • Reporting of alarms and other live conditions. • Wide-area communications, e.g., cellular or land-line telephone. • Rugged packaging for outdoor installation. • Compatibility with a corporate computer system or support by HMI/SCADA software. The team evaluates the possibility of packaging data communication equipment (DCE), such as a modem or cellular radio, or procuring a commercial,
30 | Summer 2009
off-the-shelf (COTS) dialer or notification product. Even with the packaging requirement, DCE devices represent the least expensive approach. A DCE will reside on a wide-area network, typically using cellular technology, and can be programmed to communicate with computer systems. While a DCE device can readily be adapted to discrete process measurements, cyclical measurement of such analog inputs as flow, level or pressure present problems. At a higher but still reasonable price, dialers and similar “notification” products can process the analog measurements and communicate this information to a variety of computer systems. Managing previously unmanaged assets In assessing all the locations that must be accommodated by the monitoring solution, the project engineering team soon learns why those locations are not monitored. Major issues that emerge at this stage include the fact that many sites lack power sources and are not covered by the communications technology inherent in the DCE or dialer product they are favoring. Two requirements quickly rise to the top of the key features needed in the solution: lowest possible power con-
sumption and multiple communications device options. Once the team determines that power is not available, requirements for alternatives such as battery or solar operation come to the forefront. Unless the team includes one or more engineers with extensive experience with low power system design, this aspect of the project can be protracted and possibly prohibitive. This fact quickly narrows the search to COTS devices, such as dialers, data loggers and remote terminal units (RTUs) with low power consumption as key features. Still, power systems’ costs can be high. A distinction in the industry has emerged between “low” and “ultra-low” power consumption. While a low-power device can operate using a small solar power system, e.g., 5-watt or 10-watt solar panel and a 7-amp-hour lead acid cell battery, an ultra-low power device will use only a single battery and operate for five to 10 years between replacements. The ultra-low power device represents a major savings in purchase and operation/maintenance costs related to the power source. Unfortunately, low power consumption and operation of communications devices are competing requirements. Even in the lowest-power DCEs, current draw when transmitting is over 100 mA,

Monitoring typically at 12V DC. If the device operates for long periods in this mode, the battery will drain or the solar power system will fail. Intelligent management of the DCE device is urgent and will make a major difference in overall power consumption. Project engineers must make a trade-off between power system sizing, and cost, and the frequency of communications. If the DCE is only operated once or twice per day, battery life in terms of many years is possible. A problem with many monitoring devices available today is that they have integrated only one cellular communications technology. In many areas of the world, most notably North America, multiple technologies are required to guarantee coverage. While GSM (global system for mobile communication) is available throughout the world, its use is limited in North America where operators find it available in fewer than half of their coverage areas. CDMA (code-division multiple access) is also a popular technology in North America. Still, a combination of GSM and CDMA leaves many areas uncov-
ered. While this often leads to suppliers reverting to older, hard-wired technology such as a PSTN (public switched telephone network) modem, the cost of running telephone lines out to assets such as storage tanks remains very high. To ensure communications coverage, the monitoring device must integrate at least one additional, non-cellular tech-

nology, such as spread spectrum radio. This licence-free technology provides a means for the operator to implement its own private network. Although spread
spectrum radio range is limited to about 20 miles, it is normally sufficient to reach a relay node that resides on a cellular network. Instead of operating an extensive spread spectrum network, short paths are used to access the nearest cell. Advanced functionality Very often, additional requirements for historical data logging or programmable automation emerge to meet the needs of IT, accounting or operations. Maintaining long-term or â€œhistoricalâ€? information has become a common feature in a number of COTS products. This feature is common in RTU products and is the key capability of a data logger product. The project team could spend extensive time distinguishing data loggers that include one or more DCE options from those not offering wide-area communications. A problem with many data loggers is that they offer too few DCE options to work at all locations. Programmable automation capability is also a common requirement for operations. The ability to start or stop a motor-driven device, open and close a valve, or regulate flow or level are basic continued overleaf...

Many decentralized systems employ web pages instead of SCADA HMI software. Using a standard browser, operators can view the live status of all process assets.
requirements. Even if automation is not needed, some programming capability is necessary for customized calculations. While very few data loggers offer such capabilities, they are fundamental to most RTU products.
Finally, the engineering team has determined that one product category, the RTU, meets all requirements. As a next step, the team determines that for small assets and processes, the RTU solution is too expensive.
A contemporary solution Todayâ€™s technology enables a solution that meets all basic and advanced technical requirements economically. When combined with a suitable array of communications options, an ultra-lowpower RTU can be effectively deployed in practically any location. To meet basic requirements, an I/O mix in the order of two analog inputs, four discrete inputs and four discrete outputs is fundamental. To simplify installation, the RTU must provide power to operate external transducers or transmitters, including those that use 4-20 mA current. Particularly in the case of the transmitters, duty cycle operation is a key factor. Fortunately, most asset management applications do not require highspeed scanning of measured inputs. Some take a measurement only on an hourly or daily basis. An RTU that is able to operate a transmitter for only a few minutes a day can run for five to 10 years using a single lithium battery. An ultra-low-power RTU that uses wide-temperature components eases the package design. Since many asset locations are outdoors, an IP66 or Nema 4X

Monitoring enclosure is a basic requirement. Such housings are resistant to wind-blown dust and rain. For locations such as storm drains or sewers, in which the equipment could be submerged for some time, an IP68 enclosure will be necessary. Enclosures can quickly become expensive! A compact design will curb the enclosure cost. Today, alarming and data logging functions are common in RTU products. To make the most efficient use of public networks, “push” technology should be employed. Instead of the RTU waiting for a poll from a central computer, it can initiate communications upon an alarm, event or other live condition. Push messaging via email and SMS (short message service) text can be very informative. FTP (file transfer protocol) messaging over IP networks such as GSM/GPRS and CDMA can include history files, tables and trends with significantly more information. Since push technology is event-driven, it allows more “sleep time,” which translates to longer battery life for the RTU. Its system architecture is also decentralized. Messages are directed to multiple recipients, who can acknowledge alarms using their mobile phones or PDAs (personal digital assistants). An integral web server is a major benefit, as it provides an HMI (human-machine interface) capability that can offer significant cost savings versus licensing for SCADA software. Web pages can be accessed by users anywhere in the world via the Internet or an intranet. The web pages also provide a convenient HMI for use by local technicians. In order to provide communications coverage for practically any location, a minimum offering of integral communications devices will include CDMA cellular modem, GSM cellular modem, PSTN modem and spread spectrum radio. Intelligent operation of these devices will allow long battery life and take some of the pain out of maintenance budgeting. Programmable logic is finding its way into even the least expensive RTU products. A programming environment that includes ladder logic will meet many requirements among OEMs and project engineers. A structured text language such as Basic will allow custom calculations and adapt to almost any www.esemag.com
asset management application. Microsoft Automation support also continues to gain in popularity. Full-blown IEC 61131-3 environments are also migrating down the RTU spectrum. While a broad variety of COTS dialers, data loggers and notification products are on the market, new-generation, ultra-low-power RTU products are bringing more advanced capabilities into play for wireless monitoring applications. These products provide intelligent power management, extended battery
life, input measurement, alarm management and data logging in an integrated, weatherproof enclosure. In addition, an integral webserver, “push” messaging, multiple communications options and programmable automation comprise the advanced features that often make the difference for today’s asset.

Monitoring the environmental effects of hog production in Manitoba By Dr. Dinko Tuhtar roposals for new hog production operations in Manitoba frequently stir up public controversy, with opponents and proponents providing opposing arguments. The producers often argue that their operations would comply with existing environmental and land planning requirements, while opponents question these claims and even the ability of the existing environmental laws and regulations to adequately protect the environment from the effects of hog production. Manitoba is the largest pig-producing/exporting province and the secondlargest pork producer in Canada. The pork production industry is an important segment of Manitobaâ€™s economy, contributing approximately $2 billion annually in economic activity. More than 13,000 jobs are tied directly to pig and pork production. In 2007, pig production was 9.45 million head. The industry experienced significant growth between 1990 and 2004, with a trend to larger operations and greater concentration of animals and manure in one location. Since then, growth has
34 | Summer 2009
slowed because of several factors, including hog prices, export barriers, and the value of the Canadian dollar. There are now approximately 900 pig farms in Manitoba. The existing hog production operations over 300 animal units must operate under the requirements of the current environmental legislation which specifically targets livestock, including the hog industry. The growth of pork production in the province has raised public concern about the impact of the industry on the environment, with the result that there has been similar growth in provincial environmental legislation and land use planning policies regulating livestock production. Municipal governments have been authorized to regulate the pork industry through farm building permits and land-use decision-making. The proper selection of a potential site for development of a large livestock operation, including a hog operation, is an important step in minimizing the effects of the operation on the environment, including groundwater pollution.
Manitoba, together with Saskatchewan and Alberta, has prepared and adopted a site characterization manual for the development of intensive livestock operations and construction of earthen manure storage systems. The manual takes into account the specific prairie geologic and hydrogeologic characteristics and describes the site assessment and decisionmaking process when the site and design of manure storage structures are contemplated. Guidelines and regulations In 1994, the Agriculture Department issued Farm Practice Guidelines for Hog Producers in Manitoba to manage the growth of the pig and pork industry in a sustainable and environmentally responsible manner. Guidelines have since been prepared for other operations, such as dairy, beef and poultry. The guidelines have been updated several times, most recently in 2007. The guidelines direct producers to use optimum manure management systems and practices designed to protect the environment. They describe best practices in manure handling and storage, application of manure to land, control of odour sources, hog production site selection and disposal of mortalities, and provide guidelines on how to prepare a proposal for a livestock (hog) operation. Soil sampling and analysis is an integral component of sustainable manure management. It provides information on the nutrient load of the field(s) intended for manure spreading and the potential for environmental impact, as well as a basis for nutrient requirements for planned crops. An appendix to the guidelines describes principles of soil sampling, sampling frequency (initial, periodic and annual), soil sampling debts and interpretation of analytical data, and establishes limits of residual soil nutrient loading (nitrogen and phosphorus). The guidelines, which have been developed with the participation of all stakeholders, are used by municipal governments as a tool in evaluating live-

Agricultural Wastes stock operations in their jurisdictions. At present, the provincial regulations that have the greatest impact on hog production operations are the Livestock Manure and Mortalities Management Regulation and the Provincial Land Use Policies Regulation, under the Environment Act and the Planning Act, respectively. The Livestock Manure and Mortalities Management Regulation (MR 42/98) was enacted in 1998 to ensure that the use, management and storage of manure and mortalities in livestock operations minimize the impact of these operations on the environment. The regulation, which has since been amended several times, establishes the following requirements that all livestock operations, including hog production operations, must comply with: â€˘ Design, construction, permitting, location, monitoring and decommissioning of manure storage facilities. â€˘ Monitoring and reporting on groundwater quality. This is conditional on the directorâ€™s opinion that the operation presents, or may present, a risk to soil and groundwater quality. Operations with more than 300 animal units must also sample and report on the quality of water used for animal drinking at the site. â€˘ Field storage of manure is allowed only for solid manure and with predetermined setbacks from surface water. â€˘ Manure can be composted only according to described criteria. â€˘ Manure must be transported without spills. Any manure spill over a certain threshold volume during manure transportation and manure storage must be reported. â€˘ Prohibition on livestock manure burning, unless allowed by the director in special circumstances. â€˘ Prohibition of manure discharge into surface water or groundwater. â€˘ Manure can be applied to land only as fertilizer. â€˘ Application rate of manure must take into account crop nutrient requirements and must not exceed the prescribed residual nutrient load determined by soil sampling and analysis. Nitrate nitrogen and phosphorus are principal nutrients of environmental interest. â€˘ Contractors that apply manure to land must have qualifications and hold www.esemag.com
a licence or permit required by the regulation. â€˘ Storage, handling, disposing of or applying manure onto land from livestock operations above a threshold limit (e.g., 300 animal units) must be conducted in accordance with a manure management plan previously registered with the government before certain deadlines. â€˘ Winter spreading of manure to land is prohibited, except for small hog operations (fewer than 300 animal units). â€˘ To protect overloading of the Lake Winnipeg watershed with nutrients, the Red River Valley is designated as a Special Management Area. â€˘ Disposal of livestock mortalities and composting of mortalities must follow prescribed requirements. In December 2007, the Manitoba Clean Environment Commission, at the request of the Minister of Conservation, published a comprehensive report on the sustainability of hog production in the province. Based on the commissionâ€™s recommendations, Manitoba Conservation has prepared and offered for public consultation a draft of several
amendments to the MB Reg. 42/98. The Provincial Land Use Policies Regulation was established in 1980 with the intent to provide guidelines to municipalities in preparing municipal development plans. The 2006 Planning Act amendments specified that municipal development plans and zoning bylaws must be adopted by January 1, 2008. A municipal development plan must be preceded by public hearings and must be approved by the province. It must also contain the municipal policy on livestock operations, including the siting and setback standards. Municipalities that do not yet have zoning by-laws must regulate livestock operations over 300 animal units as conditional use operations. Approval process New hog production operations over 300 animal units are required to submit their proposal to the municipality or planning district, which, in turn, forwards the application to the provincial government, which refers the application to a regional technical review committee (TRC). continued overleaf...

The TRC, composed of representatives of several governmental departments, is tasked with ensuring that the proposal is compatible with good environmental practices for farming operations. As the minimum, the proposal must
include information on the proposed hog production level and on soil nitrogen and phosphorus for fields planned for manure spreading. Manitoba Conservation reserves the right to decide whether the proposed operationâ€™s ma-
nure storage facility is in compliance with permitting criteria. TRC reports are then submitted to the rural municipality and planning district or commission. Rural municipalities hold public hearings on the proposed operation and are authorized to approve, approve with conditions, or reject the proposal. Municipal council decisions are final. While conditional use permits are site- and operation-specific, they have several provisions in common, including the character and criteria for hog confinement facilities, manure retention and storage facilities, manure spreading areas, manure disposal operations, groundwater and soil monitoring by an independent engineer engaged by the municipality, dead animals disposal, inspections, fees payable by applicants, emergency procedures in the case of contamination of groundwater or surface water, and remedies and contingencies.

Smooth coating improves pump performance ost savings have become a hot issue during these difficult economic times. Because energy consumption related to the operation of pumps represents a major expense, it is an area that requires particular attention. Energy losses in a water-circulating pump can be reduced by lining it with a coating system with a smooth surface in order to minimize friction and turbulence. This coating must also be resistant to erosion/corrosion to preserve the smooth surface. In addition, the coating system must have a low affinity for water molecules (i.e., must be hydrophobic) to delay the onset of turbulent flow and consequently reduce skin friction. Belzona® 1341 Supermetalglide was specifically designed as a hydrophobic, smooth surface coating with low surface energy and abrasion-resistant fillers. The technology produces an ultrasmooth surface that reduces the boundary layer of the pumped fluid and also reduces the internal turbulence in the
flow, thus increasing efficiency. It can help restore used pumps up to and beyond their original efficiency, as well as improve the efficiency of new pumps. Performance gains reportedly range from up to 7% on new pumps to 40% on those in service. Even polished metal pump surfaces are found to be relatively rough when examined under high magnification. Further surface roughening of the metal can result from erosion/corrosion or cavitation effects, which cause a continuous reduction in the efficiency of the system. Brush-applied Belzona 1341, which is NSF-approved and does not contain volatile organic compounds, is 15 to 20 times smoother than polished stainless steel, and, because the material is self-levelling, no special application technique is required. Original testing of the coating system was carried out under independent laboratory conditions using the fluid flow test facilities of the U.K. Department of Trade and Industry’s National
Engineering Laboratories, which are the most comprehensive pump test facilities of their type in the world. In this case, the test vehicle chosen was a single-stage, end-suction centrifugal pump with 10-inch suction and discharge branches. The pump, in uncoated condition, running at 1,300 rpm, was found to deliver 875 cubic metres per hour at 26.5-metre head with an overall peak efficiency of 83.5%. Testing of the coated pump gave a maximum 6% increase in the peak efficiency. Also, there was little change to the pump head/flow characteristics with the peak efficiency duty coinciding with that of the uncoated pump. Meanwhile, at this peak efficiency point, the power reduction was measured at 5.1 kW at duty point. Assuming a 5,000-hour operating cycle per annum, the power savings over this period would amount to 25,400 kWh. For more information, E-mail: firstname.lastname@example.org
Telemetry Close-Up HOW TO CHOOSE A SEWAGE LIFT STATION MONITORING SYSTEM WISELY! There are actually three types of Telemetry operational systems: 1 - SCADA (with radio frequency). 2 - Auto-dialer system, with a dedicated telephone line. 3 - Web-interfaced system, via a cell phone. Beware of extensive studies, personalized applications, and so on! Why not test a system offered through select suppliers and then take the time to benchmark and get knowledgeable about a few telemetry systems. Cost detailed per option: 1 - Plan for an average cost varying between $12,000 to $15,500 per pumping unit. 2 - This option is generally 30-60% more expensive on a monthly basis, without even considering installation, connection, and long-distance fees. Moreover, this type of alarm is often rerouted to a central-call system, which will then transfer it to the employee on shift, which will lead to unforeseen fees and waste of time. 3 - A typical cell monitoring system costs $2,900 per site, and you may expect service fees to go for $360 yearly. Based on all of the above information, even the best payback scenario for option 1 or 2 would take around 36 years, which makes no business sense, seeing as these calculations do not even include service calls, systems upgrades and modifications, and equipment maintenance.
Detailed description per option: 1 & 2 - These are complex transfer systems operating with software which will require frequent updates and/or a programming specialist to make any modifications. Attractive reports and graphic interface capability may be very appealing to customers, although difficult to use, but the real question is: are they truly necessary to your needs? Furthermore, alarm calls issued by these types of systems are generally imprecise (e.g. 911) and incur unnecessary service calls. 3 - The stationʼs cellular monitor issues an alarm via e-mail, telephone, or texting system of any alarm conditions pre-determined through the web interface. Data generated by your station may be accessible from any computer through a regular Internet browsing system, and it then becomes a true service station able to issue graphics, detailed event chronology per station, all of which is protected with a username and password (just as simple as online banking). There is no software to be purchased or complex programming to be done! Once an alarm has been resolved and things return to normal, you will be advised. Use Telemetry to cut daily travel, thus ensuring you have time to do regular maintenance. Itʼs really quite simple - a proper Telemetry system should transmit detailed alarm messages, and provide pump activity reports!

MBR system replaces 40 year-old WWTP plant near Brockville n 2007, the Leeds Condominium Corporation Seven (LCC7) Board made a decision to replace the existing 40 year-old wastewater treatment plant at the White House Terrace facility, located on the St. Lawrence River, near Brockville, Ontario, with a FII MicroClearTM MBR System. Their decision was based on the existing wastewater treatment plant’s inability to meet water quality discharge requirements. The property at White House Terrace consists of a hotel, 20 two-bedroom condominium townhouse units, and two three-bedroom detached single family dwellings, with a sewage flow rate of 33,450 L/d. The necessary features of the White House Wastewater Treatment Plant included: meeting stringent effluent guidelines; a compact footprint; fully automatic and quiet operation; telemetry for remote monitoring and control; modular design to allow for future expansion; and low power consumption. Filter Innovations Inc. designed the new wastewater pollution control plant in 2007. Based on the design objectives (Table 1), the Application for Approval of Municipal and Private Sewage Works required by the Ontario Water Resources Act was submitted in January 2008. The project proposal was reviewed by the Environmental Assessment & Approvals Branch of the Ontario Ministry of the Environment (MOE), and a Certificate of Approval was issued in 2008. The new system became operational in May 2009. Treatment process MicroClear membrane bioreactor technology, utilized in the project, combines a conventional activated sludge process with membrane filtration. The main treatment stages are: primary sedimentation, equalization, activated sludge biological treatment, and membrane filtration. The main treatment occurs in the aeration tank: the biological reactor. In the aeration tank, bacteria and other beneficial microorganisms consume organic pollutants (BOD5, ammoniacal nitro-

gen, etc.) as food and convert them into carbon dioxide, water, and nitrates. During this process, microorganism numbers increase and excess sludge is formed as a result. To survive and flourish, these microorganisms require the presence of oxygen. An air blower system, equipped with a low pressure alarm switch, provides air to the diffused aeration system installed within the aeration tank. Metal salt is dosed into the aeration tank, causing phosphorus to precipitate as metal phosphate to reach the MOE discharge limits. In the event that alkalinity levels (monitored by an online meter) become too low, alkali is added to maintain pH within the desired range. Treated water from the aeration tank flows into two parallel membrane tanks,
where membrane filtration occurs. The function of this treatment stage is physical filtration, and the retention of any bacteria (1-2 μm), parasites (5-50 μm), and viruses (99.99+% removal). Turbidity levels are also reduced to below 1 NTU at this stage and BOD5 levels to < 5 mg/L. The ‘heart’ of this system is the submerged flat-sheet ultrafiltration (UF) membranes, with a nominal pore size of 0.05 micron. Permeate is drawn through and out of the membranes under a slight vacuum of 0.7 to 0.1 bar. In order to keep the membranes as clean as possible during operation, permeate withdrawal is carried out on a cycle basis. The membranes provide better resistance against clogging by fibrous substances, such as hair. Excess sludge is generated as a re-

Preparing for chemical spill containment in the 21st century By Shachar Parran he number of industrial chemical spills in North America is continuing unabated. According to the US National Response Center and Environment Canada, there are more than 40,000 reported spill events annually in North America. In Canada alone, 175,000 tons of chemicals were released into the water system in 2007 (as reported by the National Pollutant Release Inventory). Despite industry having a best practice for managing these incidents, accidents will happen and managers must undertake due diligence to evaluate every possible contingency. Whether spill containment planning requires redundant systems or external systems, response time is basic to minimizing the risk and its long-term effects. Many facilities entrust their spill containment procedures to off-site,

third-party contractors, but that involves a time gap between a reported incident and the arrival of the off-site contractor. On-site, manually deployed solutions are most commonly used, but often do not have enough capacity and are not effective. There are several reasons why companies should invest in spill containment technology: â€˘ Fines have increased dramatically in the last five years. Ontario is one of numerous North American jurisdictions that have adopted aggressive measures. In 2005, the Ontario government amended its Environmental Protection Act of 1990, to include Bill 133 â€” the â€œyou spill you payâ€? law â€” under which owner-operators and directors have legal liability in the event of chemical release and fines are up to millions of dollars. â€˘ The cost of clean-up includes the cost of the contractor, chemical removal and facility downtime. Once the chemicals leave a facility and enter the envi-
ronment, the operator loses all control. The cost can reach hundreds of thousands of dollars. â€˘ The regulator expects companies to have a solid plan and the ability to execute it. Failure to meet compliance or be merely reactive to dynamic situations can be very costly to the bottom line, affect shareholders and damage a companyâ€™s public image for a long time. â€˘ Insurance costs are very high and will skyrocket for a site where a chemical spill has occurred. â€˘ In todayâ€™s business environment, the bad press that follows a nasty spill often causes irreparable damage. â€˘ Executives and directors are held personally liable for chemical spills. Directors have to ask themselves if they can defend their practices in court. Is having a pile of absorbents and rubber mats in the warehouses a defendable practice? Two methods of containment Currently, two methods are used to

Due Diligence contain chemical spills: manually deployed solutions and permanent immobile solutions, such as dikes, oil water separators and containment tanks. The most common solution is the â€œmagicâ€? spill kits, but these kits actually carry no magic. They take a long time to deploy, can only treat small quantities, and expose employees to hazardous chemicals. What would you use for a 10,000litre spill? Permanent immobile systems may offer a better solution, but they require a large investment in infrastructure. Moreover, although each type of system may provide adequate environmental protection in some circumstances, all have glaring weaknesses that limit their effectiveness. For example, dikes are a good way to contain chemical spills around drains, but there is a need to leave an opening to allow rainwater to drain. Therefore, when a spill occurs, the opening has to be blocked with emergency mobile solutions. Other shortcomings of dikes are the space required and the high cost and time to complete the project.
If one could design the perfect chemical spill containment system, what features would it have? â€˘ It would need to be able to contain the spill on-site within seconds of detection. As long as the release is contained within the facility, a release to the environment and its potential liability will be reduced or eliminated. Consider the difference between cleaning up 10,000 litres of oil from a parking lot versus remediation of a river or lake. â€˘ Automation is crucial for large facilities. Automation will also decrease the amount of employee exposure to chemicals during spill containment. â€˘ The containment system must be able to prevent any amount of chemicals from going down the drains and into the water system. â€˘ Investment in infrastructure must be kept to a minimum. Most facilities will want to avoid digging and building on-site. â€˘ Management capabilities â€” the perfect spill containment system would have C3 capabilities (command, control and communication). It should include
containment control over the entire site and a communication system (E-mail/text messages/phone), to enable the operator to contain and control the spill without leaving the operations room. An example of a company that has successfully addressed these issues is St. Marys Cement, in St. Marys, Ontario. Following a thorough analysis of its chemical spill practices, it recently installed a state-of-the-art spill containment system. An analysis led St. Marys to identify potential points of failure in its facility. The system it has installed enables drains to be plugged around the facility by pressing the numbers on the software map (Figure 1). Chemical spills have not changed, but our society, awareness and rules have changed. We can no longer hide behind the â€œwe didnâ€™t knowâ€? excuse. The technology is available to deal with spills. All we have to do is to step out of the box and adopt new ideas! Shachar Parran is with ChemiGreen Inc. E-mail: email@example.com

A challenging reservoir repair By Tim Starchuk
The complicated penetrations and attachments in this project required a significant amount of time and detail.
any municipalities are now finding that their aging underground concrete reservoirs are in need of repairs. Repairing these reservoirs properly is important from a safety standpoint but can be a complicated process. The City of Everett, Washington, experienced this first-hand when it needed to reline its Number 3 reservoir. This was a Type 1 main underground reservoir containing drinking water for the City of Everett and the surrounding community. The scope of the project involved replacing the existing geomembrane with a new HypalonÂŽ Chlorosulphonated Polyethylene (CSPE) geo-
completed before the start of the cityâ€™s high-demand season. As well, the reservoir could not be completely bypassed, because it had to be available at all times during construction to handle up to 7.7 cubic metres per minute (3 million gallons per day) of backup overflow directed to the drain sump. There were also a number of unusual difficulties in terms of geomembrane installation. Originally, the reservoir was lined with a 150-mm-thick concrete slab with copper waterstops. A number of years ago, leaking was stopped by installing a geomembrane on the slopes of the reservoir, but it did not cover the floor. Over
The reservoir lining project presented many unique challenges that added complexities and time constraints to an already difficult geomembrane installation. membrane and extending it to provide a completely lined wetted surface area. The project faced some significant challenges. Substantial leaking in the reservoir was found to be caused by the concrete slope and the floorâ€™s poor condition. There were very tight time constraints as the reservoir had to be 42 | Summer 2009
time, water from the inlet pipe wore a tear into the liner, causing it to fail. A new plan needed to be made to prevent this type of failure in the future. One of the first steps for the consulting engineering firm, Layfield, was to determine which liner would be most appropriate. The geomembrane needed to
be NSF 61 certified for containment of potable water as well as have a long-term resistance to chlorine levels as high as 50 ppm. Also the geomembrane had to be flexible, to allow it to be mechanically anchored to a number of inlet, outlet and overflow pipes, concrete columns and four unique slope columns. A custom-designed safety program was put into place, which included sitespecific requirements to deal with surge water, emergency egress, power failure procedures and air safety. All personnel on site were trained on an evacuation procedure in case of a power failure. Gaining access to the reservoir One of the first major challenges was access. The reservoir had only two 1.2 x 3.6-metre roof hatches, with one directly over a staircase. These hatch locations meant that the project materials would have to be either slid or carried up and down the narrow stairs into the reservoir. They also limited air circulation for the workers. To address these issues, a new equipment hatch was designed and constructed on the opposite side of the reservoir. The new hatch allowed heavy materials and equipment to be moved in and out with a crane, and had the added benefit of allowing workers to view the main inlet without using a boat. High-

Water Supply output fans were placed at the new hatch to solve the air circulation problem, and were backed up by air quality monitoring equipment within the reservoir. To deal with the unpredictable water surges that could not be shut off during construction, it was necessary to figure out a way to divert the water flow and plan for an emergency. To do this, a 2metre layflat bypass tube made of reinforced polypropylene was attached to the surge inflow pipe and extended into the primary drain in the bottom of the reservoir. As a safety precaution against flooding in case of tube failure, two Aqua Dams速 portable coffer dams were kept on site. These could be filled with water to dam off sections of the reservoir long enough to allow people and equipment to be rescued. With the high level of winter rains in the Northwest, rainwater would build up around the site perimeter faster than the existing stormwater removal system could handle. As a result, water constantly found its way into the reservoir through unsealed areas in the roof and perimeter. During these rain events, a steady stream of water created several problems for welding crews who were required to work around standing water. Depending on the level of water infiltration and stage of construction activity, various counter measures were required. These included using elevated welding boards to keep the welding area dry and clean, as well as dewatering by pumping, wet-dry vacuums, small mortar dams and squeegees. This issue was slowly alleviated by a contract requirement calling for the concrete construction joints to be filled with mortar one at a time. The reservoir had no internal lighting and only a limited amount of light entered through the hatch openings. Several modular high-output floodlights were needed throughout the reservoir. The easy solution would have been to use portable generators for power, but the wet environment increased the risk of electrical danger. As the crews were always working in close proximity to water, groundfault circuit interrupters (GFCI) were used on all equipment in the reservoir.

keeping the operation safe. Liner attachments Underground reservoirs usually have a large number of liner attachments due to the roof supports. This reservoir had a few additional challenges. Seven inlet
pipes required waterproof pipe boots including sizes up to 1.2 metres. In addition to the expected 32 column footings that required watertight connections, there were also four column footings located on the slopes requiring much more complicated attachments. Finally, there was a 100-metre-long seismic beam in the centre of the reservoir that required over 230 metres of watertight attachment. A particular challenge was to attach the liner to the vertical face of the column supports as it is difficult to maintain batten bar pressure around the point of the corner. The guidelines of ASTM D6497 for pipe boots and attachments were followed. For attachments on this project, 6-mm x 50-mm 316 stainless steel batten bars and 9.5-mm 316 stainless steel anchor bolts on 150-mm centres were used. The four slope columns used the same batten system modified to accommodate the slope. The pipe boots followed the standard industry attachment guidelines but were challenged by tight space constraints, concrete remedial work and dewatering requirements. To continued overleaf...

Water Supply address the problem of sealing around concrete corners, the consulting engineers designed and fabricated special compression corner clamps. The complicated penetrations and attachments in this project required a significant amount of time and detail. Failure of the first geomembrane led to significant damage in two of the reservoir’s concrete slope panels. The original project scope was limited to filling construction joints prior to relining. Once the liner system was removed, it was observed that two concrete slope panels had shifted and had significant voids underneath. The damaged panels represented 200 square metres of unreinforced concrete 150 mm thick. Removing these 30 cubic metres of concrete, was a significant problem as site and entry access for heavy equipment was extremely difficult. To compound this problem, a large amount of new liner material was already in place adjacent to the problem areas. After discussions with the City of Everett, a small remotely controlled hydraulic concrete breaker was sourced and low-
ered into the reservoir through the new hatch. The electric unit did not generate fumes, so air quality was maintained. A new sequence of installation was implemented to give the subcontractor time to remove and repair the old concrete without affecting the existing schedule.
A number of steel nuts and washers had been washed into the pipe bells, creating a potential source of damage to pumps if they found their way downstream. Once the old geomembrane was removed, the entire reservoir was washed down with fire hoses. After the cleaning, the City of Everett inspected the drain line and found that a number of steel nuts and washers had been washed into the pipe bells, creating a potential source of damage to pumps if they found their way downstream. After much debate it was
decided that the best option would be to have someone go into the 700-mm pipe. A professional diving team was hired to deal with the extremely confined space entry. A safety program needed to be put in place in the event of a worstcase scenario (possibility of a surge of 3 million gallons of water). As a safety measure, prior to the diver going in, a standpipe was installed that would prevent water from entering the pipe for up to an hour. The diver went approximately 36 metres down the pipe, equipped with surface-supplied air, a helmet-mounted camera and two-way voice communications. It took the diver approximately 40 minutes to collect all the nuts and bolts. The Number 3 Reservoir lining project presented many unique challenges that added complexities and time constraints to an already difficult geomembrane installation. However, it was completed two days ahead of schedule and met all performance and water test requirements. Tim Starchuk is with Layfield Group. E-mail: firstname.lastname@example.org

Black & Veatch’s water treatment facility earns American Public Works Association awards he Geneva Water Treatment Facility, designed by Black & Veatch, was named a 2009 Project of the Year Award winner and a Public Works Project Excellence Award winner by the Chicago Metro Chapter of the American Public Works Association (APWA). The Public Works Project Excellence Award is given to one Project of the Year Award recipient that “defines excellence and the advancement of the profession by the following criteria: greatest impact on the future of public works; best innovative application of an existing or new technology; on time, safe completion; and best example of advancing the field of public works.” When new regulations made it necessary to mitigate elevated levels of radium in the local deep aquifers, the city seized the opportunity to build a new treatment facility that not only removed radium, but also provided softened water for the community of approximately 19,000 people. The Geneva facility replaced an existing

water system that included only iron removal for its shallow wells and direct use of its deep wells without softening. Sustainable solutions, advanced treatment processes, including membrane filtration and a high degree of automation, are incorporated in the new 8 million US gallons-per-day treatment facility’s design. To blend the new treatment plant in with its surroundings, the facility was designed to look like a large agricultural barn and is located on a 40-acre park-like site surrounded by wetlands, open space and a bike trail.
The creative use of space and plant hydraulics greatly reduced life cycle costs for the city. The city followed sustainable practices by choosing conjunctive use of the aquifers to minimize the impact on the area’s water resources. In addition, Black & Veatch designed an elevated aerator to allow gravity flow of the filtered water to the finished-water reservoir, which eliminated the need for a transfer pumping station. The aerator is hidden in the top of a 55-foot-tall silo, which complements the barn. The creative use of space and plant hydraulics greatly reduced life cycle costs for the city.

Beijing praised for its water and wastewater performance during Olympics
eijing, China, achieved and largely exceeded the drinking water and waste management goals it set as part of its bid for last summer’s Olympics, according to a new report. “Beijing prepared impressively in these areas for the Olympic games. In the end, the city improved its drinking water, as well as its waste disposal and recycling systems,” said Cy Jones, a senior associate at the World Resources Institute (WRI) and lead author of two chapters within the report. WRI’s research - covering the water and waste chapters found that the city’s drinking water treatment plants met China’s new water quality standards and guidelines set by the World Health Organization. Beijing also expanded its wastewater collection and treatment systems, enabling the city to treat 92 percent of its wastewater during the games. “Though many more actions are needed to ensure the longterm sustainability of its water supply, Beijing’s aggressive efforts before the Olympics show that it’s possible for cities to minimize water consumption, maximize the use of available rainwater and treated wastewater, and protect critical surface-water resources,” Mr. Jones added. “Beijing’s efforts and our recommendations can act as a guide for future Olympic host cities.” In addition to improving water quality, Beijing surpassed its goal of sorting 50 percent and recycling 30 percent of all solid waste produced within the city by 2008. Upgrades to the city’s waste disposal system allowed 52 percent of waste to be sorted and 35 percent to be recycled by 2007. Furthermore, Beijing greatly expanded its ability to properly dispose of hazardous waste in specially designated landfills. In 2001, four plants could properly dispose of 2,000 tons of hazardous waste per day combined. In 2008, the city increased that capacity to 30,000 tons and recycled an additional 10,000 tons. “A big step forward has been made by the Beijing municipality in terms of waste disposal and recycling,” said Hanqian Zhang, a WRI researcher and report co-author, based in Beijing. “Olympic bid commitments were achieved through effective infrastructure investment, wise urban planning, technology research, and education programs.” The authors found that Beijing’s water management leading up to the Olympic Games serves as an example to other cities of how to achieve maximum efficiency in the use and management of scarce water resources. Beijing should con-
tinue its efforts. Furthermore, the International Olympic Committee should promote the development and implementation of environmentally sound water and waste management in all cities being considered for future games. The report, entitled Independent Environmental Assessment: Beijing 2008 Olympics Games, was produced by the United Nations Environment Programme (UNEP). Data was provided by the Beijing Municipal Government, the Beijing Environmental Protection Bureau, and the Beijing Olympic Organizing Committee. For more information, visit, www.wri.org

Rubber 'barges' for oil transportation and spill containment
he Dracone barge may not be a household name, but, for coast guards around the world, this gigantic rubber bladder is part of the first response kit in an oil spill. The Dracone barge is somewhat of a misnomer since it looks nothing like a
canal barge. In fact, it looks more like a beached whale on land, and, at sea, like a giant sea monster. According to Wikipedia, the name Dracone is a reference to science fiction author Frank Herbert’s Dragon in the Sea novel. “It was called a barge for legislative

and classification reasons,” says Mike Saunders, Business Development Manager, Trelleborg Dunlop GRG, which manufactures the units on demand for coast guard authorities. Dunlop GRG (General Rubber Goods) is based in Manchester in the UK. A Dracone barge is basically a vessel for transporting any kind of liquid – from jet fuel to crude oil, from point A to point B, without the need for the infrastructure of a tanker. A tugboat usually drags the barge through the water. It floats because of large buoyancy panels on either end, but also because many of the liquids that it transports are lighter than water. Sir William Hawthorne, a Cambridge University engineering professor, invented the Dracone barge in the late 1950s following the Suez oil crisis. He was better known for his work developing the jet engine, but also had an interest in energy. Over 500 have been produced since his invention. The largest unit can accommodate more than 935 cubic metres of liquid, is 91.5 metres long, 4.23 metres in diameter, and weighs 6.5 tons empty. It can, however, fold up into the size of a medium van. The barges are made from woven nylon, coated with synthetic rubber polymers for high abrasion resistance. Their lifespan is about 25 years and they are reusable. There could be a major growth market for them in the cruise ship industry.

Cruise ships still have to empty their bilge, waste and sewage water while anchored offshore.
â€œCruise ships are getting larger and larger and are having a harder time entering ports, but they still have to empty their bilge, waste and sewage water while anchored offshore,â€? says Saunders. How it cleans When an oil spill occurs, the oil is first contained with booms. Skimmers then set to work collecting the oil, water and other debris into a funnel, with the help of a pump attached to a hose at the bottom of the skimmer. The spill is pumped into the Dracone barge for discharge at land-based disposal facilities.
Rescue missions While Dracone barges are not the first items to capture world headlines during an oil spill, they are instrumental in mopping up the mess. Some famous disasters in which they have been used include the Exxon Valdez spill and Hurricane Katrina in New Orleans in 2005. After the hurricane, clean-up crews used them to empty the fuel tanks of capsized boats and ships.

Fifty years of remediation projects at West By Fabiano Gondim and Craig Murdoch Hamilton Closed Landfill he West Hamilton Closed Landfill site in Hamilton, Ontario, was in operation from around 1942 until it was closed in 1975. Efforts to remediate the site began in 1957. The total waste footprint is approximately 23 hectares. The site accepted primarily domestic, commercial and industrial solid wastes from the north and west parts of the city of Hamilton. The landfill was developed in a north-south direction in an existing wetland. The water table is about 2.5 metres below ground surface in the southern part of the site, and 5 - 6 metres below the ground surface in the middle to northern part. Flow within the shallow aquifer is generally westward towards Chedoke Creek. It has been more than 50 years since the first capping of the landfill (known at the time as the West End Dump) took place in an effort to control odours, diseases, rodents, litter, scavenging and visual impacts. Since then, a number of remediation projects have occurred, reflecting advancements in regulations, environmental responsibility, public funding management and available technologies. Figure 1 shows the remediated areas of the landfill and a summary of key remediation projects undertaken at the site from 2004 to 2008 to control leachate impact. These included: 1. Purge well: As a temporary solution to remediate the major leachate seep that was discharging into Chedoke Creek, a leachate purge well (130 metres north of the site entrance) and forcemain (100mm diameter) to pump leachate to the sanitary sewer were installed in 2004. 2. Pond remediation: A pond on the eastern side of the landfill was filled/abandoned in 2005 because it was a potential contributor to leachate and a potential source of mosquitoes and West Nile virus proliferation. 3. Re-grading and re-capping: The site was fully re-graded and re-capped with clay in 2005/2006 to minimize infiltration of rainwater and consequent leachate generation. Existing soccer fields and

baseball diamonds as part of the site (currently known as Kay Drage Park) were reestablished and improved. 4. Chedoke Creek bank stabilization and leachate management: An assessment of the area concluded that improvements were required to reduce bank erosion, improve slope stability and control leachate seeps of the east bank of the creek. Based on an evaluation of alternative remedial measures, the revegetation of the area, the installation of hard slope protection (bioengineering) and the installation of a leachate collection system
were chosen as the preferred solution. The planning and design for this project followed the Municipal Class Environmental Assessment (EA) process for Schedule â€œBâ€? projects. The design phase and tender package was completed in June 2007 by Dillon Consulting and Urban & Environment Management. The project was tendered in June 2007 and the contract was awarded to Rankin Construction for $2.3 million to build the north portion of the project, which has an approximate extension of 500 metres from the site entrance

All increek works were completed in late September 2007, including armour stones, perforated piping to collect leachate (300-mm diameter, laid at a 0.1% slope), geosynthetics, crib walls and log vanes (to increase fish habitat). The pumping station is remotely operated though a SCADA system by the municipal wastewater treatment plant. The project won the 2009 Ontario Public Works Association project of the year award (environment category between $2 million and $10 million). 5 and 6. Storm sewer replacement project: Two existing 900-mm storm sewers were identified as reaching the end of their operating life. The project was completed in June 2007 and replaced 168 metres of sewer, HDPE pipe, 900-m diameter, SDR17 and 56 metres of 900-mm concrete storm. The total cost, including consulting fees, was approximately $1 million. A total of $8.1 million was spent on remediation projects for the West Hamilton Closed Landfill site between 2004 and 2008. Fifty per cent of the eligible costs were funded by the Ontario Millennium Partnership Fund and the other 50% by the City of Hamilton. It is anticipated that the following benefits will result: • Enhancement of public health and environmental protection, including surface water quality improvements at the Chedoke Creek. • Improvement to community servwww.esemag.com

Floating geomembrane cover improves biogas By Jim McMahon collection s one of Canada’s biggest and oldest manufacturers of cornrefined ingredients, Casco Inc. makes products that are used in industries from food and beverage to pharmaceuticals to paper manufacturing. Combined, its three Ontario-based manufacturing facilities process 4.5 million bushels of corn each month. One of its plants, located in the town of Cardinal on the St. Lawrence River, is among the most automated corn wet milling facilities in the industry. Opened in 1858, and processing 70 million pounds of corn monthly, the facility manufactures high-fructose corn syrup, glucose, specialty starches and corn oil. Along with its high volume of production, the plant needs to process a continuing effluent of organic waste, an average of 792,000 gallons of wastewater per day. Eighty per cent of this effluent is processed through an anaerobic digester. Casco’s bulk volume fermenter (BVF), designed and built in 1988 by ADI Systems, is limited to receiving 641,000 gallons of wastewater per day, as set by the Ontario Ministry of the Environment (MOE). This effluent is generated from several areas of the plant through the wet milling process, in which various components from the exterior and interior of the kernel are mechanically and chemically separated. A softened-kernel mixture is ground in a mill to separate the starch and gluten
from the hulls. The protein, called gluten meal or corn meal, is then separated from the starch. The starch is either refined into sugar or turned into foodgrade or industrial-grade starch by employing surfactants (surface active agents) to produce chemical modifications in the granules. This process accounts for ten percent of the wastewater effluent going into the BVF. During the conversion process for changing the starch to sugar, ion exchange resins are employed, requiring the use of hydrochloric acid and caustic for regeneration. The initial regeneration flow, along with any sugar that is rinsed out with the resins, goes out as wastewater to the BVF reactor, accounting for 70% of the plant’s total effluent. Various other processes at the plant supply small volumes of effluent to the BVF. Biogas collection Anaerobic digestion is widely used to treat wastewater sludges and organic waste because it provides volume- and mass-reduction of the input material. Casco’s raw solids are added directly into its BVF for digestion. Comparatively long retention times, typically greater than seven days, and the large physical size of the four-million-gallon bioreactor with a high volume of biomass maintained in it, work together to provide the system with inherent stability against shock conditions caused by organics and solids loading, and temper-

ature and pH fluctuations. The biological breakdown of organic matter in the absence of oxygen gives off primarily methane, but also carbon dioxide and some traces of hydrogen sulphide, which together are labeled biogas. Although biogas-derived methane and carbon dioxide come from an organic source with a short carbon cycle, they still contribute to increasing atmospheric greenhouse gas concentrations. This is diminished, however, when biogas is combusted. This energy release allows biogas to be used as a fuel to run heat engines or to generate mechanical or electrical power, making anaerobic digestion a renewable energy source. The Casco plant has used a geomembrane cover on its BVF bioreactor since it became operational. In 2008, the company upgraded to an improved-design floating, insulated geomembrane cover with a streamlined capability to collect biogas. The cover captures all of the biogas from the BVF treatment process. Without a cover, the biogas would be released to the atmosphere. Designed and built by Geomembrane Technologies Inc. (GTI), this new cover is collecting an average of 236,000 cubic feet of biogas per day from the bioreactor at a 65% methane concentration. “Over the past two years, Casco’s 20year-old cover was getting to where it needed to be overhauled or changed,” says Victor Cormier, an engineer with

Energy From Waste GTI. “It was beginning to inhibit biogas collection. Our latest cover design is significantly different from the previous cover, which fluctuated up and down with the wastewater level inside the tank. This new design is a trampoline type, with no folds and a very taut fit for better biogas collection.” Casco’s new cover is made up of a one-inch layer of polyethylene foam laminated to polyethylene sheeting on the wastewater-facing side. The top layer is a non-laminated sheet of 40 mil specialty PVC (ethylene interpolymer alloy) that acts as a gas-tight barrier to keep the biogas from passing through. It also incorporates a weave design that provides maximum strength-to-weight ratios. Since this topsheet is exposed to the sun, it is equipped with advanced UV inhibitors. The polyethylene sheeting and insulation are perforated to allow the biogas to pass through and become trapped by the top layer. This design has exceptional seam strength, extreme puncture and tear resistance, low thermal expansion and contraction properties, a wide range of chemical resistance, high flexibility, and
dimensional stability under high loads and temperature fluctuations. The cover works under a vacuum, using a blower system that keeps the gases withdrawn and suctioned underneath it. The system incorporates a novel floating-beam design that creates a tentlike effect, giving extra migration paths for the biogas to follow. All panel sides of the cover are bolted down to make a gas tight seal. Once collected, Casco’s biogas is then flared, although the company is examining options for utilizing the biogas within the plant. Importance of heat retention The efficiency of the BVF bioreactor, i.e., its ability to maintain digestion of the continuously incoming influent, is critically dependent on keeping its temperature at 25–32 degrees C. This is particularly important in Casco’s cooler, northern-climate location. Heat loss in large volumes of wastewater translates to energy loss, and lost heat must then be compensated for by adding heat. Casco supplements its BVF with heat generated from its refinery wastewater, which is intentionally heated to maintain
the bioreactor’s temperature. Casco’s new cover provides a heightened level of insulation to hold heat better within the reactor, and its snug fit reduces heat loss to a greater extent than the previous cover. Elimination of water evaporation, prevention of ice buildup within the reactor, and reduced sunlight penetration also help maintain proper water temperature. These factors all contribute to reducing Casco’s energy consumption. Control of a potential unplanned biogas release and its attendant odour, which is generated mainly from hydrogen sulphide, prompted Casco to move forward with the new upgraded cover. Standards set by the Ontario MOE do not allow methane to be released to the environment. Casco needed to be sure that the cover on the BVF would meet these standards. Complicating the problem was that just 150 feet from the bioreactor is a residential neighbourhood, so an unplanned methane release could present a safety hazard. “GTI was doing regular inspections on the original cover,” says Gerald Morand, process engineer and environcontinued overleaf...

Our technicians were no longer able to walk out on the cover to take measurements of sludge levels. Because of this and the environmental and safety implications, we made the decision to replace the cover.â€? A challenging cover switch Because of the possibility of an unplanned biogas release, GTI completed
the project quickly, in less than three weeks. A critical factor was the need to execute the cover switch without stopping the wastewater flow from manufacturing. The solution involved diverting some of the plant effluent away from the BVF to the aerobic lagoon while the work was in progress. â€œWe were concerned with the activity of the BVF unit while the cover was off,â€? continues Mr. Morand. â€œExposed to the air, we expected the bioreactor to have a decrease in activity, so we didnâ€™t want to

overload the system. We decreased the COD going to the BVF by 55%, leaving enough influent to keep the biological activity up, but diverted the balance directly to the aerobic lagoon.â€? The bioreactor is located directly adjacent to the St. Lawrence River, with only 25 feet of clearance available on three sides of the system. The fourth side was space-limited by a railroad line. This posed challenges both with removing the old cover and installing the new one. GTI had to manufacture and transport the new 130 x 410-foot cover in four large, folded and rolled sections. The rolls were placed directly onto the BVF water one at a time with heavy equipment, opened and connected together using the GTI floating-beam design.
Companies that upgrade to the latest cover technology will find themselves in a better competitive position, particularly as energy costs continue to escalate and become an increasingly critical factor in plant operations. â€œThe floating beams allowed us to connect the large cover panels together without having to weld them,â€? Mr. Cormier continues. â€œWe minimized the use of heat, because we didnâ€™t want to ignite the biogas. We also removed the old cover at the same time the new cover was being installed to limit the release of biogas.â€? Inevitably, manufacturers with anaerobic wastewater bioreactors will gravitate to more energy-efficient cover systems to maximize biogas collection and usage, streamline their operations and improve their bottom lines. Those companies that do upgrade to the latest cover technology will find themselves in a better competitive position, particularly as energy costs continue to escalate and become an increasingly critical factor in plant operations.

Regionalization of wastewater treatment in Central Alberta By Stephan Weninger and Pervez Sunderani n the autumn of 2005, following several years of robust population growth and increasing demands on area watersheds, Alberta Environment advised the municipalities in the Central Alberta region that continuous wastewater discharges into a sensitive stretch of the Red Deer River between the Dickson Dam and the City of Red Deer Water Treatment Plant’s intake would be phased out. With 150,000 people in two dozen urban and rural municipalities relying on this segment of the watershed, the department needed to find a new way to keep operations running. Considering the centralization of wastewater treatment and disposal as an initiative consistent with both its Sustainable Resource and Environmental Management (SREM) policies and the Water for Life Program, which is aimed at protecting water resources and ensur-
ing access to quality sources of water, the department determined that centralizing wastewater treatment and disposal would be its best option. A reduction in the number of wastewater treatment plants and lagoons discharging to the Red Deer River was also considered preferable to upgrading or replacing the six wastewater treatment plants in the area that were operating at or over capacity and were up for approval over the next few years. To begin moving forward with a plan, Alberta Environment then invited several of the urban municipalities in the region – the City of Red Deer and the Towns of Lacombe, Blackfalds, Sylvan Lake, Innisfail and Olds – to provide representation on a steering committee to oversee the development of a conceptual design for a regional wastewater transmission system or systems extending north, south and west of the City of Red Deer.
In February 2006, the steering committee retained the engineering firm, Stantec, to develop regional transmission and treatment options, to identify priority areas for system connections, and to identify governance and rate structure options for the resultant regional system or systems. Making connections The conceptual design identified a “core area” of priority system connection and a secondary servicing area, in which connection to a regional system was deemed less critical because of low wastewater impact on the Red Deer River sub-basin, the capacity of existing facilities to meet current demands, proximity to the centralized area, or a combination of those factors. The core area consisted of 14 municipalities, requiring the addition of over 150 km of wastewater transmission lines continued overleaf...

with a price tag of $252 million. Servicing both the core and the secondary areas would require 300 km of transmission mains at a capital investment of $394 million. With these estimates in hand, Alberta Environment hosted an information session for elected officials and media in April 2006 and received immediate buy-in from several municipalities. Over the course of the next several months, Alberta Environment worked with Alberta Transportation, the provinceâ€™s capital projects funding arm, to devise a roll-out strategy that would address the needs of sustainable growth and environmental protection in the subbasin, while meeting budgetary constraints during a period of high growth and rapidly inflating construction costs. The province decided to move ahead with the plan, first focusing on services for the core area by augmenting at the City of Red Deer Wastewater Treatment Plant with the South Leg, a 90-km system to connect the towns of Innisfail, Bowden and Olds, and Mountain View County to the Red Deer plant. Once the connection plan moved through preliminary design, the system would then in56 | Summer 2009
corporate the Waskasoo Regional Sewer System, a 30-km gravity and forcemain system built in 1984 to connect Red Deer County and the Town of Penhold to the Red Deer plant. Meanwhile, the municipalities of the core area worked with the province to develop the Central Alberta Regional Wastewater Master Plan, which established the guiding principles and timelines for the development of regional wastewater infrastructure in Central Alberta. On its completion, the master plan was endorsed by the 16 municipalities of the core area. Planning for growth On the governance front, the core area municipalities branched into three separate groups, each applying to become a regional commission. Under the provinceâ€™s Municipal Government Act, regional commissions are similar to municipalities, with power to establish bylaws and accrue assets and debt separately from member municipalities. As a result, the South Red Deer Regional Wastewater Commission (SRDRWC) was created in August 2008, and included the towns of Penhold, Inn-
isfail, Bowden and Olds, and the counties of Red Deer and Mountain View. The Sylvan Lake Regional Wastewater Commission (SLRWWC) was created in October 2008, and included the Town of Sylvan Lake, Red Deer County, Lacombe County and the summer villages of Jarvis Bay, Norglenwold, Half Moon Bay, Sunbreaker Cove and Birchcliff. The North Red Deer Regional Wastewater Services Commission (NRDRWWSC) was also created in October 2008, and included the towns of Blackfalds and Lacombe and Lacombe County. The City of Red Deer agreed in principle with the plan to provide wastewater treatment to the SRDRWC, subject to confirmation that the group was able to upgrade its own plant to meet its longterm treatment capacity needs. To this end, an updated City of Red Deer Wastewater Treatment Plant Master Plan was needed to assess the current plant capacity and to provide a plan for phased plant expansion to meet city and regional growth needs over the next 50 years, over which time plant capacity would be expanded from the current 35 MLD to over 300 MLD.

Wastewater Treatment In December 2008, the city engaged Stantec to complete the year-long master plan update, which included the first complete review of the plantâ€™s biosolids management system as well as its longterm strategy for wastewater treatment. A project steering committee was also established, including representatives of the city, Alberta Environment, Alberta Transportation, the SRDRWC and Stantec. Planning for an eightfold increase of influent wastewater flows involved a complete revision to previous facility capital planning. While the newest bioreactors at the plant have a 12.5MLD capacity, future upgrade phases had to be significantly larger just to meet the short-term needs of the new regional legs, let alone city growth. Conversely, sizing of the new components had to be small enough to be built within project timelines and local industry capacity, and to avoid stranding capital investment and the budget. Also of importance, the team had to consider how the continued development of the area and the diversification of the economy would change the characteris-
tics of the influent wastewater in a city with additional loadings from large meat processing and oilfield service industries. Ultimately, the major liquids treatment components were sized to 25MLD capacities in each phase, with one phase roughly representing the respective 25-year needs of each of the three regional transmission legs and the other related to the City of Red Deerâ€™s expected growth. The phases will each be developed based on the collective treatment capacity needs of the city and the three regional systems, with new phases coming on-stream every five years to coincide with demand growth. In order to shoehorn as much treatment capacity as possible onto the plant site, future primary and secondary clarifiers will be arranged in long, rectangular shapes instead of the current circular configurations. This will also facilitate a future conversion to membrane biological nutrient removal (MBNR) technology. At present, biosolids from the treatment process are stored in sludge lagoons on-site and disposed by land application on local agricultural fields

Wastewater Treatment which is being tendered this spring. The overall SRDRWC system is expected to be completed by the end of 2011. The SLRWWC is developing the west leg of the Central Alberta Regional Wastewater system. The Sylvan Lake area is a rapidly developing residential and recreation area, and the Town of Sylvan Lake has consistently ranked among the fastest-growing communities of its size in Canada over the past decade. In addition to the town, seven municipalities (summer villages) surrounding Sylvan Lake will need service connections. The Town of Sylvan Lake operates an aerated lagoon system that also services the summer villages of Jarvis Bay and Norglenwold, while the remaining unserviced developments around the lake are currently using septic tank-truck haul or on-site systems. The SLRWWC is currently proceeding with interim upgrades to the Sylvan Lake WWTP in order to extend septage haul services to the remaining lakeside communities until a regional transmission line extension to the Red Deer WWTP is established.
wastewater discharges until the development of the 30-km regional transmission system to service their communities and growth areas of Lacombe County. With the exponential growth Central Alberta has experienced over the last several years, it is no surprise that the regionâ€™s infrastructure is beginning to reach its limits. Expansion plans must consider not only the increasing capacity needs of their service areas, but also the important environmental and economic effects those changes will have both immedi-
ately and as the region continues to grow. By centralizing wastewater transmission and treatment into regional hubs, as this Red Deer example shows, municipalities can ensure continued service to their residents with manageable costs and minimize the impacts their operations have on the surrounding environment.

The SLRWWC is currently proceeding with interim upgrades to the Sylvan Lake WWTP in order to extend septage haul services to the remaining lakeside communities until a regional transmission line extension to the Red Deer WWTP is established.

New municipal drinking water licenses issued Members of the Ontario Municipal Water Association are among the first five municipalities to have successfully applied for the new Ontario municipal drinking water system license. They are Huron County, the City of Hamilton, the City of Kingston, Halton Region and the Town of Tecumseh. Development and implementation of the Municipal Drinking Water Licensing Program is based on Justice O’Connor’s recommendations in the Part II Walkerton Report. The report recommended that the Ontario Ministry of the Environment require all owners of municipal drinking water systems to obtain a license to operate their systems. It also recommended that the owners and operating authorities of these systems implement a quality management approach to operations and management. According to the Ministry, it is the first quality management system of its kind in North America. The license is based on continuous improvement of day-to-day operations. It consolidates a number of existing approvals into one, including a permit to take water, a drinking-water works permit (formerly a Certificate of Approval), an operational plan, an operating author-

Recently, a small group of the old members decided to reactivate the Front Wave idea. The New Front Wave Inc. (NFWI) will act as a ‘club’ for retired scientists and engineers. One goal of NFWI is to act as a permanent depository and a distributor of specialized personal experiences. The club will gather information about the specific experience of each retired member and will make direct contact between the member and a potential end-user of their expertise. NFWI will contact organizations such as the Canadian National Research Council, the Canadian Environmental Assessment Agency, Sustainable Development Technology Canada, and other government agencies as well as large Canadian industrial organizations. It will ask them to suggest problems that need solutions. If NFWI can find, or develop one, it will try to sell the participating organization the solution to the problem they needed solving.

Canadaâ€™s new Environmental Enforcement Act sets minimum fines for serious offences of between $5,000 for individuals and $500,000 for large corporations. As well, the Act raises maximum fines to as high as $6 million. It also gives enforcement officers new powers to investigate cases and grants courts new sentencing authority that ensures penalties reflect the seriousness of the pollution and wildlife offences. The Act also expands the authority to deal with environmental offenders by: specifying aggravating factors such as causing damage to wildlife or wildlife habitat, or causing damage that is extensive, persistent or irreparable; providing fine ranges higher for corporate offenders than for individuals; doubling fine ranges for repeat offenders; authorizing the suspension and cancellation of licenses, permits or other authorizations upon conviction; requiring corporate offenders to report convictions to shareholders; and, mandating the reporting of corporate offences on a public registry. Fines imposed by the courts will go to the Environmental Damages Fund which provides funding for local environmental restoration, improvement, research and development.

The federal government recently announced up to $779,817 in funding from the EcoAction Community Funding Program for 23 projects in Québec. The total value of these projects is $2,682,625. In the Mégantic region, Environment Canada has contributed $82,167 to the Action Belles Rives Grand Lac SaintFrançois project, which aims to renaturalize 300 shoreline properties. This riparian strip will improve the lake’s health and is effective in preventing blue algae. To maximize the project’s impact, the participating shoreline residents will have to be committed to the revegetation of their properties, to using phosphatefree dishwashing soap, and to not using pesticides or fertilizers on their lawns. www.ec.gc.ca/ecoaction

Billions of litres of sewage escape treatment According to a recently released report by EcoJustice, tens of billions of litres of untreated sewage are discharging annually into Ontario’s waterways, because of outdated sewage infrastructure and poor oversight by the provincial government. “Flushing Out the Truth: Sewage Dumping in Ontario”, highlights Ministry of the Environment (MOE) figures that show the total volume of sewage dumped from municipal treatment plant bypasses was approximately 18 billion litres in 2006 and 15 billion litres in 2007.

bined sewer overflows and the incomplete information being collected by the MOE. “Sewage is the largest source of water pollution in the Great Lakes,” says Elaine MacDonald, Senior Scientist for EcoJustice. “The fact that the Ontario government fails to even monitor it correctly demonstrates poor planning and dangerously uninformed decision-making.” In total, eight municipalities dumped more than one billion litres of untreated or undertreated sewage through bypasses during the 2006-2007 period. Niagara Falls released almost 7 billion litres of untreated or undertreated sewage in 2007 alone. Other cities with more than a billion litres of sewage released during 2006-7 include: Hamilton (5 billion); Windsor (4.3 billion); Welland (3.9); Toronto (2.7 billion); Sudbury/Greater Sudbury (2.6 billion); London (1.8 billion); and Leamington (1 billion). www.ecojustice.ca
BC leaders urged to tackle water shortage and privatization issues Water experts in British Columbia are urging politicians to address public concern about water safety and shortages. A 2009 Canadian Water Attitudes Study, administered by Ipsos Reid, showed that the long-term supply of freshwater is a top concern for Canadians, second only to health care availability and financial market stability. Yet, when polled, BC’s two main political parties are willing to address only some of the concerns presented in a recent survey which was sponsored by eight leading organizations. Some highlights of the poll include: • Over 600 waterways in BC have been staked for the development of privatelyowned Independent Power Projects with licensing that does not involve public input and has major loopholes around environmental assessments. The Liberal Party does not plan to slow private power development to allow these issues to be addressed. The NDP does plan to stop the current “gold rush approach” and evaluate cumulative environmental impacts of runof-river projects. • BC has the worst rate of water-borne diseases in Canada, yet the Liberals do not plan to make drinking water quality continued overleaf...

NEWS standards legally binding as recommended by the World Health Organization. The NDP have made this policy change a possibility. • Neither of the two major parties committed to ensuring adequate water flows for fish and the environment through legally binding water allocations. The Green Party committed to this step. • Though BC is the only province in Canada that does not require a government licence for groundwater extraction, the NDP did not commit to regulating groundwater withdrawals, while the BC Liberals did. • Most current water demands can be met with far less water than is currently being used. Both the Liberals and NDP are considering the creation of water efficiency standards for agriculture, industry, commercial and residential use.
Feds to lower phosphorus concentration limits In the Canada Gazette, the federal government has tabled “Regulations Amending the Phosphorus Concentration Regulations. The amendments include provisions that will lower the phosphorus concentration limit for household laundry detergents from 2.2% by weight of phosphorus to 0.5%, and clarify that a concentration limit of 2.2% still applies to commercial and industrial laundry detergents. Phosphorus concentration in household dishwashing compounds and cleaners will be limited to 0.5% by weight.
The amendments also specify that, for the purposes of the Regulations, any analysis for the determination of the concentration of phosphorus shall be conducted by a laboratory accredited under the International Organization for Standardization Standard ISO/IEC 17025:2005, and whose accreditation includes the analysis of phosphorus within its scope of testing. According to a Canadian Water and Wastewater Association communiqué, the amendments will decrease the release of phosphorus into the environment by an estimated 28,400 tonnes over 25 years. Benefits are expected to include reductions in phosphorus removal at wastewater treatment facilities, improvements in water quality in Canadian lakes and rivers, and reductions in human and environmental exposure to algae blooms. There will be an additional reduction of 5,100 tonnes of phosphorus that are released directly into the environment from untreated wastewater. The complete text of the regulation is available at: www.gazette.gc.ca

Greenpeace activists arrested after protest On July 8, eleven Greenpeace activists were arrested after they unfurled a 2,275 square foot banner on Mount Rushmore that challenged President Barack Obama to show stronger leadership on the climate crisis. The demonstration coincided with the G8 leaders’ summit in L’Aquila, Italy, where discussions about the global warming crisis were scheduled to take place in the lead up to UN climate treaty negotiations in Copenhagen this December. Specifically, Greenpeace is calling on President Obama to: • Cut emissions in the US by 25-40 percent by 2020, compared to 1990 levels. • Strive to keep global temperatures as far below a 2 degrees • Join with and encourage other members of the G8 to Celsius increase as possible, compared to pre-industrial establish a funding mechanism that provides $106 billion levels. per year by 2020 to help developing countries adapt to • Set a goal of peaking global emissions by 2015 and be global warming impacts that are now unavoidable, and to as close to zero as possible by 2050, compared to 1990 halt tropical deforestation. levels.
