Comment by Peter Davey

Working towards net zero energy consumption in wastewater treatment plants

Marc Roehl

Current advanced technologies, including vertical loop reactors for biological wastewater treatment, can reduce power requirement for aeration by more than 25%.

R

ising gas prices continue to attract attention and rouse anger among motorists. At the end of the nineteenth century, however, the petroleum industry was fortunate enough to obtain two cents for each gallon of gas sold. In most cases, gasoline – seen as a useless by-product of kerosene refinement – was surreptitiously poured into rivers. What accounted for gasoline’s price raise was not changes in composition, but realization of its potential.

Looking back on the countless gallons of gas sold for pennies, it is easy to laugh and remark how foolish our predecessors were. Yet, as growing developments in wastewater treatment suggest, present practices may be future material for historic humour.

Wastewater, which consumes sizable amounts of energy to treat effectively, contains enough potential energy to cover costs many times over. The idea that wastewater treatment plants could achieve net-zero energy usage, and even net energy production, is gaining momentum.

Marc Roehl, P.E., Product Manager

6 | January 2011

of Biosolids Technology at Siemens Water Technologies, says that energy efficiency has become a focus point for designers and municipalities looking to upgrade treatment plants.

An advocate of achieving energy efficiency through two approaches, Mr. Roehl argues for increasing both efficiency and energy recovery.

Wastewater treatment accounts for some 30- 40% of municipal energy usage, and 30% of a typical plant’s operational costs is electricity. As such, reducing energy consumption is an essential budgetary concern in our age of austerity.

In addition to reducing carbon footprints through curtailing electricity consumption, potent greenhouse gas components of biogas can be captured and utilized to further reduce energy taken from the grid. Sizable gains can already be made through equipment and process investment.

Energy efficiency Installing modern pumps, mixers and blowers of increased efficiency, in conjunction with variable frequency drives, decreases energy use and plant maintenance costs. Aera-

tion treatment developments, including fine-bubble diffusers, dissolvedoxygen control systems and addition of anoxic zones, are crucial for reducing WWTP energy use.

Aeration typically accounts for almost 55% of a municipal wastewater plant’s energy use. According to Mr. Roehl, while new aeration technology offers great returns on investment, some of the largest gains can occur when more wastes are treated under anaerobic conditions. In addition to maximizing biogas production, anaerobic treatment requires substantially less energy than aerobic treatment. This seems to be a rare case of economic and environmental convergence.

Energy recovery While efficiency optimization aims to reduce energy required to run treatment plants, recovery seeks to increase the energy produced during operation. In the U.K., biogas has been used since the late nineteenth century, when gas collected from local sewage plants fuelled streetlamps.

Increased energy recovery from continued overleaf...

Comment by Peter Davey biogas requires increasing production through improved anaerobic digestion, along with greater gas capture and storage capacity. “Biogas is really a no-brainer in terms of trying to find ways of recovering energy,” Mr. Roehl said when interviewed by ES&E. “It is an available and often under-utilized energy source, going hand-in-hand with wastewater treatment. Biogas, compared to other sources of energy capture, offers the benefits of working within existing processes and plants. Beneficially, using biogas is simply an addition to the process rather than an additional process.”

Along with biogas, biosolids offer another source of fuel, though one which requires a substantial amount of additional infrastructure in order to be fully utilized. Moreover, the benefits of energy produced must be weighed against energy required to dewater and transport the biosolids.

These waste-to-energy plants consume negative value fuel – that is, people pay you to collect this fuel, and produce revenue generating electricity. This seems to be an exceptional case of having one’s (sludge) cake and eating it too.

Modern waste-to-energy plants are able to reduce volumes of original waste by approximately 90%.

Then, through incineration, contaminants that could be potentially released through other disposal methods are destroyed.

8 | January 2011

In Odessa, Ukraine, a power generation plant turns 50,000 tons of dewatered sewage sludge into 33,507,000 kWh, with emissions lower than that of liquefied petroleum gas.

In Canada, the Liberty Energy Center, currently under construction in Hamilton, Ontario, hopes to power two 5 MW steam turbines with 470,000 tonnes of biomass and biosolids annually. In Ontario, renewable energy and energy efficiency projects have been spurred on by the Green Energy Act. By 2025, Ontario plans on reducing peak electricity demand by 6,300 MW, while doubling renewable energy production to 15,700 MW. The pairing of wind and solar power generation with WWTPs, has been gaining recognition and attention as alternative energy continues to gain traction. Erecting turbines on vacant land within treatment plants, or installing solar panels on roofs, works towards plant sustainability through energy generation.

Limitations Unfortunately, the widespread achievement of net-zero energy plants is not feasible with today’s technologies. Given existing technology and methods, WWTPs are currently able to achieve a 20-30% reduction in energy expended in wastewater treatment. When combined with a co-generation power plant – able to meet 25-35% of a

plant’s needs – a net energy reduction of 40-60% is achievable. However, this is far from the goal of net-zero energy.

The East Bay Municipal Utility District (EBMUD) treatment plant in Oakland, California, is a model for plants working towards net-zero energy. EBMUD installed variable frequency drives and new blowers, discontinued second stage activated sludge mixing, and operated thermal and co-generation energy production.

While it has not yet achieved netzero energy status, the investments and process enhancements save the facility an estimated $2.8 million annually.

Separating the best possible plants of today from becoming net-zero, is what Mr. Roehl described as, “a technology gap”. However he predicts that within two to three years, emerging technology and process advancements will allow for even greater energy efficiency and energy recovery. This could make net-zero energy plants a reality, which will be a milestone event in the history of wastewater treatment.

Risk assessment and municipal wastewater – what are the benefits? By Karen A. Phillipps and Gordon Brown

Potential health impacts include fish consumption and recreational uses of water.

H

uman health and environmental impacts related to municipal wastewater are emerging areas of interest for a number of reasons. These include increasing concern regarding the viability and sustainability of public water supplies, concerns about people’s health and the environment, and regulatory changes.

Recently, the Calgary office of Intrinsik Environmental Sciences Inc. was contracted to complete several environmental health risk assessments related to municipal wastewater projects in Alberta.

1. What is environmental risk assessment?

Environmental risk assessments are conducted to identify potential chemical and microbial hazards to human health and environmental quality. Potential hazards are assessed by determining maximum chemical and microbial substance concentrations in water, fish, and wildlife in contact with the receiving river water, and by comparing these to toxicologybased exposure limits for those substances. Background river water quality is taken into account, so that overall cumulative risks can be determined.

In this manner, safe municipal waste10 | January 2011

water effluent quality criteria can be identified. Typically, risk assessments often include recommendations for ongoing monitoring of the effluent and river in order to determine whether effluent quality criteria are being maintained. Necessary actions can quickly be taken, if and when quality criteria are exceeded.

The process by which risk assessments are completed has been developed and endorsed by government agencies such as Health and Environment Canada, Alberta Environment, and the United States Environmental Protection Agency.

All risk assessments, including those that are completed for wastewater projects, are based in principle upon a general risk assessment paradigm.

2. How is risk assessment used for wastewater projects?

Facility operators or municipalities may wish to have risk assessments completed for a variety of reasons. In some instances, there may be communities downstream of a wastewater outfall that have specific concerns about their health or water quality and associated environmental impacts.

For example, Intrinsik completed a comprehensive human health risk assess-

ment for a wastewater project upstream of an aboriginal community. It included an evaluation of potential health impacts relating to drinking water, traditional food consumption, traditional and domestic water use, local foods and fish consumption, and recreational uses of water (e.g., swimming).

Increasingly, the evaluation of potential human and environmental health risks posed by wastewater discharges is the result of recent provincial regulatory requirements linked to the CCME’s “Canada-Wide Strategy for the Management of Municipal Wastewater Effluent”.

3. Do risk assessments have to be completed in Canada?

In 2009, the Canadian Council for Ministers of the Environment (CCME) introduced the Canada-Wide Municipal Wastewater Strategy. This strategy includes sampling and testing requirements, National Performance Standards, and recommendations for the completion of environmental risk assessments in support of the determination of site-specific environmental discharge objectives (EDOs). These requirements impact new and upgraded facilities in different ways, depending on facility size, type of dis-

Environmental Science & Engineering Magazine

Jan2011_ES&E_D4_ES&E 11-02-02 2:04 AM Page 11

Wastewater Treatment charge (continuous vs. intermittent) and flow rates.

Testing requirements specified by the CCME vary with respect to the number of samples per year to be taken, and the types of analysis that are suggested. Data from the collection of these samples can be used in completing risk assessments.

Examples of parameters that are discussed within the CCME Wastewater Strategy include: ammonia, total suspended solids, carbonaceous biological oxygen demand, total residual chlorine, Escherichia coli, total coliforms, and various chemical parameters, such as metals, volatile organics, pesticides, and polycyclic aromatic hydrocarbons.

Intrinsikâ&#x20AC;&#x2122;s approach to wastewater risk assessment has focused on the potential water uses associated with the receiving water body for wastewater effluent, stakeholder concerns, and the amount of historical environmental quality information available for the particular project.

4. How is a risk assessment completed?

Risk assessments may be completed with a focus on human health, ecological health (such as fish and other aquatic organisms), or both, depending on the facility and the area in which it is located. The CCME definition includes both human and aquatic health, but is very general with respect to outlining specific requirements.

A basic, screening-level risk assessment includes a comparison of measured concentrations of chemicals, nutrients and microbes against established criteria (such as the CCME community drinking water guidelines, or the CCME freshwater aquatic life criteria). Such assessments are key in evaluating and deriving site-specific objectives under the CCME framework.

In the interest of human health protection, a more comprehensive approach to risk assessment can be used in tandem with a screening level assessment or as a follow-up project. This more comprehensive approach might include a quantitative assessment of the total dose of chemicals that a person might be exposed to from drinking water, bathing or swimming, and fish consumption.

If an operator or regulator were concerned about the concentrations of metals such as mercury from the wastewater in fish, the comprehensive risk assessment would be a means of providing this type of risk information.

5. What are the benefits of completing a risk assessment?

Human health and ecological risk assessments provide means of identifying and managing environmental risks. These assessments provide meaningful, scientifically-based information to operators and to the public and other community stakeholders. Completion of risk assessments can build upon or serve as the basis for the development of public consultation programs, and aid in building and maintaining positive relationships between operators and stakeholders.

The outcomes of risk assessments may be useful in that they may identify areas of potential interest to a municipality, such as mercury concentrations in fish, cyanobacteria, eutrophication, or microbial issues.

Wastewater Treatment

Using a continuous-fill, intermittent-discharge SBR to remove biological nutrients By K. Khier Chibani

The plant has three continuous fill, intermittent – discharge sequencing batch reactors.

F

ive years ago, the Town of Essex, in southwestern Ontario, decided to upgrade its facultative lagoon treatment systems with an alternative wastewater treatment plant — a continuous-fill, intermittent-discharge sequencing batch reactor (CFID-SBR) system, targeting even higher effluent quality.

The CFID SBR process was designed

by Premier Tech Aqua, which also provided major process equipment for the high-performance treatment plant. Engineering for the construction was designed and provided by Stantec Consulting Ltd. (Windsor). The plant is being operated by the Ontario Clean Water Agency.

The plant has three CFID-SBR reactors with a total average capacity of 4,590 m³/d (flow rate estimated for the next 20 years). Provision has been made to expand the plant further, with 33% more capacity, by building a fourth reactor to treat an ultimate design flow of 6,120 m³/d.

The Essex Sewage Works was commissioned in early January 2006, and since then the CFID-SBR system has consistently met the effluent requirements.

Six months after a successful start-up of 12 | January 2011

the first two reactors, process performance testing began. Warm-period testing started in the last week of July and continued through August, September and October. This was followed by cold-period testing for four more months: November, December, January and February.

When the plant had successfully passed the two testing periods with two reactors in operation, testing was continued at higher flow (inflow/infiltration) in March and April 2007, with only one reactor in operation. The CFID SBR demonstrated its ability to efficiently handle a constantly changing flow with highrate inflow/infiltration.

SBR design approach The main treatment objectives for the CFID SBR were to achieve reduction of biological oxygen demand (BOD5), total suspended solids (TSS), ammonia, and total phosphorus (TP). Chemically assisted phosphorus removal was used to ensure that the SBR consistently met effluent requirements for total phosphorus.

Microbial growth kinetic coefficients for heterotrophic bacteria, as well as nitrification kinetic coefficients, were based

on the ASM model (Henze et al. 2000).

Kinetic coefficients given at 20oC were adjusted to design temperatures using the Arrhenius equation.

Mass balance and prediction of sludge production were based on modeling of the suspended growth treatment process, considering heterotrophic biomass, cell debris, nitrifying biomass, nonbiodegradable volatile suspended solids (VSS) in influent and inert TSS in influent (Metcalf & Eddy, 2003).

Each of the three basins has an effective volume of 1,567 m³, leading to oneday hydraulic retention time at average dry weather flow (design flow).

Biological process simulations using BioWin as a platform were also part of the design. The simulations considered cycle time and the particular hydraulic management of the CFID SBR and tracked the variation of the concentrations of pollutants being treated. Two main scenarios were explored. The first one considered wastewater with cold temperature 8oC. In this case, effluent quality for ammonia and BOD remained below the limits.

The second scenario assumed a 50% higher flow per reactor, lasting a whole week. This would be the case, if one out of the three reactors was suddenly out of service for a week. Simulation results confirmed that the CFID SBR system, as designed, would meet targeted effluent criteria.

Field data and performance results For March and April 2007, one reactor configuration had to face a continuous, extremely high hydraulic load, most likely due to water infiltration and inflow. Average design flow per reactor was exceeded by more than 70% and maximum treated daily volume was on average 4.6 times the design average daily flow. Hourly peak flow reached 150 L/s, which is 8.5 times the average design flow per reactor.

Influent pumps were equipped with variable frequency drives (VFDs) and indeed the influent intensities were progressively increasing and decreasing.

The CFID SBR sequence was not just jumping between two modes (normal

Wastewater Treatment mode and storm mode), instead, it was continuously and smoothly adjusting every five minutes to the variation of the inflow. Treatment steps were automatically and progressively shortened, or extended, depending on influent variations.

At all times, the system was able to make best use of the process equipment, thereby extending the cycle of treatment every time it was possible.

SBR mixed-liquor temperature was significantly affected by influent temperature, and both SBR and influent temperatures were affected by ambient temperature. Environment Canada reported that the average monthly ambient temperatures for March and April 2007 for the Windsor area were 4.2oC and 8.5oC, respectively.

The SBR was roofless and quite exposed to weather conditions. Consequently, in March and April 2007, both factors (influent and ambient temperatures) contributed to cooling the SBR, which is unhelpful for treatment performance. Although January and February were the coldest months, the impact on the SBR was less visible because of low precipitation and, therefore, low water inflow/infiltration.

It happens that with excessive high incoming flow, the time for the treatment cycle is reduced considerably, meaning the static-fill step is skipped almost regularly and the fill-settle step is reduced progressively to about 45 minutes per cycle. This may well have contributed greatly to gradually diminishing the effectiveness of the biological selector effect and thus raising the SVI number.

Analyses of effluent TSS for March and April 2007 confirm this observation about settling deterioration under stress conditions. TP concentration in the effluent also displayed the same trend as TSS, despite alum dosing. Note that dosing was on average at 49 μL of liquid alum per litre of wastewater. The mole ratio was on average around Al:P 2.2, based on an estimated 2.38% w/w phosphorus assimilation in VSS biomass (Eckenfelder & Grau). Chemical sludge made up about 8% of total sludge, which might have contributed to maintaining relatively good settling.

Organic matter concentrations expressed as COD and BOD showed the plant had no difficulty at all in demonwww.esemag.com

strating an excellent performance. Even with one reactor in operation, BOD was consistently below 5 mg/L. Full nitrification was observed. Even at low temperatures, total ammonia in the effluent remained well below the target concentration of 1 mg/L. For the last testing with one reactor in operation for three months, total ammonia did not exceed 0.6 mg/L on average. This means the treatment cycle as engineered provided enough aeration time to complete

the nitrification reaction.

Also important was that filling with wastewater during settling and decanting did not affect the quality of the effluent, thanks to the baffle wall.

Nitrate (NO3) and nitrite (NO2) concentrations in the influent were monitored on a regular basis, similar to the rest of parameters reported above. On average, total influent concentration (NO2+ NO3) was below 0.25 mg/L, so the imcontinued on page 80...

Regulations

Businesses everywhere may soon be affected by programs like Toronto’s ChemTRAC By Shawn McDonald

A

recent bylaw in Toronto is indicative of the growth of municipal regulations concerning emissions to the environment. Although currently only applicable to the City of Toronto, other municipalities are certainly considering similar regulations. This means industries elsewhere should also take note.

In December 2008, Toronto City Council passed its Environmental Reporting and Disclosure Bylaw. As part of this bylaw, Toronto Public Health has introduced the ChemTRAC program. It requires all Toronto businesses, unless specifically exempt, to report their annual use and release of 25 chemical compounds, if they meet certain reporting criteria.

ChemTRAC is similar to Environment Canada’s National Pollutant Release In14 | January 2011

ventory (NPRI), except that the reporting thresholds are significantly lower, as low as 1% of the NPRI thresholds for most compounds. In addition, while many NPRI-listed substances also have an annual employee-hour threshold of 20,000 hours (about 10 employees), ChemTRAC does not include such a threshold.

The rationale behind these differences in reporting thresholds is to elicit reporting from small- to medium-sized organizations. As of 2009, less than 0.5% of all registered companies within the limits of the City of Toronto report to NPRI on an annual basis. This is partially related to a lack of awareness and enforcement of NPRI requirements, but may also be due to many businesses being too small to meet federal reporting thresholds.

To put the (NPRI) thresholds into context, a facility would have to consume

more than 12,000,000 cubic metres of natural gas to meet the 20,000 kg/yr threshold for nitrogen oxides, a by-product of combustion. A metal-working facility would have to use over 30,000 kg of 300 series stainless steel to meet the 10,000 kg/yr threshold for non-hexavalent chromium. Many, if not most, small and medium-sized Toronto businesses will not meet those thresholds.

ChemTRAC thresholds are available at www.toronto.ca/chemtrac.

The City of Toronto’s Environmental Plan has identified significant data gaps in information available to the public on sources of contaminant releases at the local level. As a result of the lower mass reporting thresholds for the ChemTRAC program, Toronto Public Health estimates that between 4,000 and 7,000 Toronto continued overleaf...

Regulations businesses will have to report their uses and releases annually. Reported data will be made available to the public.

At this time, the City intends to use the program as a data collection initiative, to be enforced by City bylaw officers.

Fines for non-compliance will range from up to $5,000 for a first offence to $100,000 for continued violations.

The bylaw lists sectors and sources exempt from reporting. These include facilities engaged solely in retail sales; food and accommodation services; medical and dental offices; construction sites; fuel sales, distribution and storage; and general vehicle repair facilities, other than auto body shops, and parts repair and remanufacturing.

Based on the North American Industrial Classification System (NAICS) code, the ChemTRAC program is being phased in to apply to specific sectors or services over a three-year period. The first group of sectors is, or should be, currently monitoring their annual use and release of the listed chemicals. If they trigger reporting, their first report will be due June 30, 2011. There are about 2,700 companies in the Phase 1 group currently operating in Toronto.

Phase 2 companies include chemical wholesalers, medical and diagnostic laboratories, waste management and remediation services, dry cleaning and laundry services, auto body repair and auto parts repair facilities, and funeral services. The first reports for these companies will be due June 30, 2012.

All other facilities, unless otherwise exempt, will be phased in by January 2012, with reports due June 30, 2013.

This last group will include metal and metal products manufacturers, hospitals, universities and schools, office buildings with reportable activities such as printing or power generation, and potentially even small businesses such as hairdressers, if target compounds are used and released in sufficient quantities.

A number of resources are being made available to Toronto businesses to help them assess their annual uses and releases and, if necessary, to report to ChemTRAC. Along with a general guide to reporting, Toronto Public Health is making available over 50 spreadsheet calculators, designed for use in a variety of industrial sectors and processes. By en16 | January 2011

tering a few simple production inputs for the reporting year, the calculators will estimate chemical uses and releases to air for ChemTRAC substances. These can then be reported through the Cityâ&#x20AC;&#x2122;s online reporting platform. This reporting platform was still in development at the time of this article.

Through a partnership between the Toronto Region Conservation Authority and Partners in Project Green, students are also available to conduct free site visits at interested companies. They will review the companyâ&#x20AC;&#x2122;s processes, existing environmental reports and permits, and provide guidance on what information needs to be collected and reviewed to complete a ChemTRAC assessment.

The City is also providing Toxics Reduction Grants ranging from $1,000 to $25,000, to fund initiatives that educate workers and help businesses achieve longterm reduction or elimination of the use and release of ChemTRAC substances.

Grants are available to business associations, unions and labour organizations, neighbourhood associations and community groups, charitable organizations, and environmental organizations operating in Toronto. Grant applications will be accepted between January 3 and March 11, 2011. These grants are not available to individual businesses.

It is intended that information reported to ChemTRAC will be publicly disclosed, although the manner in which

The level of training and experience needed to complete the reporting will vary as widely with the complexity of the process and the number of chemicals in use.

To complete an assessment, facilities will be expected to review annual production information, purchasing records, and the chemical composition of all products manufactured, processed, or otherwise used on-site. If measurements of the amount of each target chemical used and released were not taken during the reporting year, totals can be estimated.

Estimates of annual uses and releases based on annual processing and purchasing records can be calculated using published emission factors, which determine emissions per unit of input (e.g., kilograms released per unit of product produced). Or mass balance calculations can be used. They assume that the quantity of a compound on the input side of a process should be equal to the amount on the output side emitted as finished product, waste, and surface water or air emissions.

Depending on the number of sources and processes at a facility, the total of material safety data sheets to be reviewed for reportable substances, and the experience of the person or team completing the assessment, reporting could be the work of a few hours, or a few weeks. The level of training and experience needed to complete the reporting will vary as widely with the complexity of the process and the number of chemicals in use.

this will occur and the level of detail provided is still under consideration by Toronto Public Health staff. Although the ChemTRAC program is not designed with contaminant emission limits, other similar regulatory programs have shown that increased awareness of chemical uses and releases from a facility, as well as public disclosure of that information, can motivate industry efforts to reduce their uses and releases, without making these reductions mandatory.

The Massachusetts Toxics Use Reduction Act was successful in reducing statewide toxic waste disposal by 50% in 10 years, without legally requiring companies to do so. In Canada, the NPRI has been credited with reducing air emissions by 27% in 17 years. This is due largely to improved tracking of releases and increased public awareness of pollution sources at the community level.

Although there are no numerical targets in terms of pollution reduction, it is the goal of ChemTRAC to motivate the same awareness and accountability for Toronto businesses.

Operations

Tapping into experienced water and wastewater professional talent By Doug Cooper and Joe Levack

M

uch has been said and written about the forecasted shortage of qualified and experienced water and wastewater operators over the next five years. This shortage, if predictions come true, will have an adverse effect on water and wastewater treatment across North America as there are more operators reaching retirement eligibility than there are new ones entering the industry.

Industry veterans will tell you that a lot has changed since they began their careers in the 1970s and 1980s, with increased liability, reduced resources, and a raised bar with regard to entry level requirements. They have had to study, write exams and, at least on paper, become more like scientists. While these may all be good things for the consumers of potable water and those committed to protecting our drinking water resources,

it should not be surprising that it has affected the number of potential employees.

Also, consider the culture and behavioral tendencies of the next generation of employees. They suffered along with their parents through the various downsizing, right sizing, plant closures, business failures and retirement fund losses arising from scandals such as WorldCom and Enron, the bankruptcy of GM and Chrysler, as well as the boom/bust of the dot coms. In short, they have matured in a world that has demonstrated selfishness, disloyalty and greed.

They are also the information generation. Technology has empowered them like none before with the internet, e-mail, text messaging, instant messaging, cell phones, social networks and satellite communications providing unlimited access to television and radio stations from across the globe.

Despite increasing concerns related to the proficiency of the basics in Math and English, this is also the best educated generation ever. No longer is a high school diploma sufficient to secure a good paying job. The bachelor degree of today is now the equivalent to the high school diploma of the 1980s. This level of education leads to two inevitabilities.

This generation is entering the workforce later than their parents, and they feel a greater sense of entitlement to more re-

Environmental Science & Engineering Magazine

Jan2011_ES&E_D4_ES&E 11-02-02 2:05 AM Page 19

Operations warding and prestigious work, with a high degree of workplace independence and creativity.

All of this leads to a generation entering the workforce that is substantially smaller than the generation that is exiting.

They are less willing to make a long-term commitment to an employer and less willing to work longer hours than contractually required. In many cases, they are entering the workforce with the financial pressure of student loans. They have the expectation that the top jobs will soon be vacant and that they will be trained and ready to assume those positions without having to put in years to prove themselves.

In the water and wastewater industry specifically, there has been much dialogue about how to deal with the shortage problem, how to generate interest in the industry, and how to keep moving towards the concept of highly-skilled, highly-trained certified operators. Many municipalities have found themselves trying to deal with shrinking budgets while trying to maintain sufficient operational resources. Take your average municipal drinking water system, perhaps rurally located, and provide them with the answers as to how they can attract and keep staff at competitive rates and you will be considered a genius.

For the most part, all of this talk seems to be geared towards the “surrendering and acceptance” notion that veteran operators will soon move on, so what are we going to do?

However, we believe there is tremendous opportunity to tap into the talents of veteran operators and that it does not have to be all or nothing. Here’s what we know.

- No number of new operators can replace the accumulated knowledge, handson skills and experience of a veteran.

- Just as a container of milk does not go sour at midnight on the posted expiry date, veteran operators do not become incapable on their first day of retirement.

- For many long time operators, work has been a significant part of their life.

- Not many municipalities can afford to hire new operators for any significant degree of mentoring overlap.

- There are veteran operators out there who actually wish there was a way they could help in the transition and who get personal gratification from passing on www.esemag.com

knowledge to their junior colleagues.

The World Water Operator Training Company understands this potential and is proactively responding to this situation by looking for veteran operators who feel that they still have something to offer. Potential exists for these veterans to serve as an Instructor/Training Specialist, or as part of our “Operation & Maintenance Problem Solving Services” team.

After all, the skill sets for both are essentially similar when you consider the value of their hands-on experience; their desire to help or coach others; their experience “problem solving” or finding answers to challenging questions; their presentation or facilitation skills; their desire to stay somewhat active; and importantly, their ability to translate their experience into resolutions or instruction.

The WWOTC Problem Solving team is comprised of seasoned veterans who are knowledgeable and experienced in the day-to-day challenges of operating and maintaining water and wastewater systems. Working with on-site operators, their role is to provide the tools to optimize existing process streams, assessing

for improving performance, reducing costs and ensuring due diligence in meeting regulatory requirements.

They are able to offer on-site operational-coaching/mentoring, on-site “quick-response” support for problems, operational assessments, process optimization, and equipment and computerized maintenance.

In summary, the void that exists now is fully expected to get bigger. So whenever possible, we must explore every opportunity to retain the valuable skills of veteran operators. Experienced operators have been in the proverbial trenches and, while credentials are certainly needed, experience is vital. We firmly believe that there is a need for these valuable skills, resources and experience to be put to work.

Cover Story

Environment Canada staffer develops system to rapidly sample groundwater and sediments in moving waters

A

t roughly 2,000 kilometres long, the Columbia River is the largest river in the Pacific Northwest region of North America. It was here in 2008 where Environment Canada’s Peter Krahn, tasked to take samples as part of an environmental assessment, faced an almost impossible situation.

“I had to get samples from the river, but there was no possible way to collect them. The water moved too fast, the river was too deep, and there was heavy rock cobble at the bottom,” said Krahn. He then came up with an innovative groundwater sampling device that he thought could do the job. Two years later, Environment Canada has filed a patent application on the K-Interstitial groundwater sampler, or “KIST Sampler”, to collect groundwater and sediment core samples in the toughest of conditions.

When groundwater rises up into an overlying river, lake, or ocean, it is said to “upwell”, or behave like an artesian spring. When this water is contaminated, chemicals “upwell” into the overlying body of water along with the groundwater. Collecting a sample of this groundwater just before it upwells is important for testing its chemical composition, potential toxicity and environmental impact.

This is especially true in an emergency spill situation, when samples reveal groundwater quality and the zone of environmental impact.

Collecting impacted sediment cores is another important step in this sampling process. This allows testing of pore water concentrations for their potential impact on fish and benthic invertebrates. Yet, getting core samples in areas of significant water depth, or where there are high risk factors (such as fast currents, hazardous bottom structures, or turbidity) can be difficult and dangerous.

Fast and effective, the KIST Sampler uses attachments to collect interstitial groundwater samples in the hyporheic zone (where groundwater and surface water mixes) and in substrates, from 20 | January 2011

Environment Canada’s Peter Krahn, P. Eng (right) and enforcement officer Justice Merembe prepare to deploy the KIST sampler to collect a sediment sample from the bottom of the Fraser River, British Columbia, using the split spoon attachment.

coarse sands to river cobbles of 15 to 22.5 centimetres in diameter. Depending on current flow, the sampler can be deployed to the location at depths exceeding 30 metres. Depending on substrate porosity, small volume water samples for chemical analysis or large volumes for fish bioassays can also be collected.

Other “direct push systems” used for groundwater sampling apply force at the

upper end of a probe, usually at the water surface. In deep water with fast currents and heavy rock cobble bottoms, this upper application of force can cause the probes to bend, snap and fail. The KIST Sampler generates the penetrative force required, using a patent-pending slide hammer system.

It provides both anchoring mass and upwards of 2,000 psi impact force at the

Environmental Science & Engineering Magazine

Jan2011_ES&E_D4_ES&E 11-02-02 2:05 AM Page 21

Cover Story bottom of the probe, directly to the peizometer sampling tip. Interchangeable components allow the mass to be increased above the slide hammer (to increase impact force), below (to increase anchoring force), or both. The slide hammer force is also reversible, allowing the probe to be easily extracted after sampling is complete.

“We really set out to create a tool that was portable and able to operate in the harshest of conditions, where other equipment or divers could not,” noted Krahn. “Drilling wells in an off-shore environment is inherently risky, expensive, and can require large boats or bargemounted platforms,” added Krahn. “The KIST Sampler is deployable on a variety of platforms, from 4-metre inflatable boats to jet boats or off-shore boats.”

The sampler’s main adaptability comes from its numerous potential attachments. The peristaltic (or roller) pump attachment collects the desired volume of sample at the required extraction rate. A conversion attachment can connect split spoon samplers that collect sediment cores in various substrates, from clay and silt to coarse sand. Another conversion attachment allows connection of a shielded peizometer to collect pore water samples at discreet depths.

An underwater camera attachment can accommodate single or 360-degree views in real-time, still or streaming video settings. The camera helps operators with site selection, examination of bottom substrate, and depth of penetration confirmation. The video can also be recorded directly to a laptop computer for later examination and editing.

These attachments also help make the sampler easy to use. Operation requires three people: one person to operate the winch, one to help feed cables and hoses during deployment, and a final person to monitor the real-time camera and data logger.

Results so far speak for themselves.

The device has already been successfully used to collect legal evidence of upwelling groundwater at current speeds approaching 2.0 metres/second and 10 metres deep in heavy river cobble. Tests are underway to deploy at over 30 metres depth.

For samples which are gas sensitive or very hazardous, Environment Canada has www.esemag.com

gone one-step further, developing a “Safe Sampler” system. This isolated atmosphere system can be coupled with the KIST Sampler to collect hazardous, or atmosphere sensitive, groundwater samples from the hyporheic, epibenthic or water column zones.

The “Safe Sampler” system is a robust

field design that can be operated at the sample site, protecting both the sample and the sampler from cross contamination, hazardous chemicals and gas sensitive conditions.

Stormwater Management

Redeveloping former military base required innovative stormwater management approach

T

he Currie Barracks redevelopment lands are located in southwest Calgary, Alberta, at the site of a former Canadian military base. Phase 1 is comprised of approximately 14.6 ha of single and multi-family residential units and public space. The full site (~83 hectares) is a pilot project for LEED Neighborhood Development in Canada and has received a Gold rating for the approved plan.

Existing stormwater infrastructure servicing the area was near capacity and a sustainable stormwater management solution was required. Provincial regulatory agencies require decreased stormwater pollutant loadings to receiving streams.

Due to downstream storm sewer constraints, post-development releases to the system from the Currie Barracks site are more restrictive than in many new developments.

To provide for ongoing performance of the stormwater system during the Chinook dominated winter months, underground infiltration storage facilities are being installed in key locations to accept street runoff.

veloper, secured the services of AMEC to undertake the stormwater engineering work, and Progressive Engineering to complete the landscape architecture designs for the community. In order to meet their objectives and adhere to local regulations, AMEC and Progressive Engineering worked together to develop a Low Impact Design (LID), using natural materials first and moving to more engineered solutions as required for stormwater management.

This LID approach addresses post-development release rate requirements while also improving water quality. Several different design solutions, materials and products are incorporated into the design and include: rooftop rainwater harvesting; rain gardens; vegetated swales; gravel infiltration trenches; sump catchbasins with non-clogging weirs; infiltrating underground storage; redirection of stormwater from streets into rain gardens via curb-cuts; and creation of a raingarden/dry pond.

The main goal was to utilize LID techniques to maintain and/or restore the natural hydrological function of this site and meet the low discharge capacity available in the existing storm sewer system. At the same time, the plan meets the City of Calgary guidelines for storm-

water management.

Low Impact Development technology is based on a shift in perception, viewing stormwater as a resource rather than a nuisance to be dealt with. By implementing more natural methods of handling stormwater, this technology facilitates a more natural runoff hydrograph that reduces erosion and sedimentation, thereby providing improved water quality.

The Currie Barracks project represents the first time in Alberta that LID is being used to this extent to manage stormwater flows. Furthermore, the project team is implementing several features to account for Calgary’s unique climate, so that the system will be operational during the winter and the freezethaw Chinook cycle.

To avoid overloading the minor (underground) system, and to achieve the desired infiltration volumes in the stormwater Best Management Practices (BMPs), Inlet Control Devices (ICDs) were provided at some catch basins to promote infiltration through the base of the catch basins during smaller storm events.

AMEC and Progressive Engineering also engineered a weir system to attach to catch basins in the rain gardens to minimize potential clogging of very small ICDs. During large storm events, the

Environmental Science & Engineering Magazine

Jan2011_ES&E_D4_ES&E 11-02-02 2:06 AM Page 23

Stormwater Management catch basins will operate conventionally, with attenuated peak flows controlled by the ICDs. To provide for ongoing performance of the stormwater system during the Chinook dominated winter months, underground infiltration storage facilities are being installed in key locations to accept street runoff. These facilities are not subject to damage caused by freezing. Due to their design, they will remain operational even during large, rapid temperature changes.

Part of the BMP system is an organic component, which includes a thick layer of topsoil and compost with shrubs, perennials, or sod above. The soil mix and plant material assist with evapotranspiration, filtration, and erosion control.

The biological component also facilitates primary treatment prior to stormwater entering the existing storm sewer system.

Traditionally, park space and stormwater management have been designed and developed separately. In Currie Barracks they are designed together as complementary elements, combining LID with landscaping, including pathways, plazas, historical military monuments, and shrub and perennial plantings.

Modelling of LID features is a new and developing field. The modelling for this project revealed that the size of the minor storm sewer system could be reduced while still creating a robust stormwater management design. To ensure a safe and reasonable design, the modelling integrated several traditional

www.esemag.com

stormwater models.

The design incorporates a number of small LID structures located throughout the site. These structures are connected to traditional stormwater facilities and storage structures, to ensure the ultimate peak runoff rate is within the set limits.

Liaison with the City of Calgary was required while adding LID technologies to the traditional stormwater engineering standards. This project required a team approach for both design and approvals, to ensure that the LID technologies being implemented were acceptable to the developer, engineers and regulatory bodies.

A conventional minor system is being implemented that will be capable of capturing the remaining flows up to the 1-in5 year rainfall event. The major system, which includes overland flows when the LID facilities and minor system capacities are exceeded, is capable of safely

conveying flows up to the 1-in-100 year recurrence event, as required by the City of Calgary.

In the event of failure or freeze-up, the minor and major systems are designed such that they will function the same way as a conventional storm sewer system, with the attenuation of peak flows from the catch basin ICDs and underground storage.

The ability of the system to trap, contain and treat contaminated stormwater, prior to entrance into the existing storm system, provides an additional margin of safety for downstream uses. This is an important added benefit, as some of the stormwater from the site eventually flows into the Glenmore Reservoir, Calgaryâ&#x20AC;&#x2122;s main source of drinking water.

Pollution Prevention

Trap system captures floating waterway litter

Anchored above the flood line, the Bandalong litter trap is able to collect any floating trash and direct it into a basket that is extended into the channel.

I

n the southeastern United States, the Satilla River stretches throughout Georgia’s wetlands, before emptying into the Atlantic Ocean at the Cumberland Sound. Along the river’s path, just miles from the famed Okefenokee Swamp, is the city of Waycross. The city’s drainage canal is a Satilla River tributary, draining more than 8,000 acres of urban development.

Although trash in the Satilla River was of little concern to regulators, the large volume transferred by stormwater runoff and discharged by the canal system concerned local residents and the Satilla Riverkeeper.

Because there was no legal obligation to remove floatables from the river, Waycross was severely limited in its ability to receive federal aid. Four years earlier, the city had applied for a state grant and was rejected. However, it still strove to be a steward for the environment. Eventually funding came from a variety of sources, including the Green Infrastructure Pact and the American Recovery and Reinvestment Act. Finding financial support for this project wasn’t the only bump in the road.

Pairing the right system with this site was no easy task. Because the location is in a 24 | January 2011

flood plain, the device had to be below the last confluence point. The area didn’t allow for any kind of fixed infrastructure.

The Bandalong Litter Trap, available from Storm Water Systems, seemed to be the answer. In comparison to other potential solutions, it is very inexpensive. Additionally, because the trap isn’t anchored within the stream itself, it minimizes the amount of disturbance to the stream buffer. Anchored above the flood line, it is able to collect any floating trash and direct it into a basket that is extended into the channel.

The adaptability of the product also allows for drastic changes in flow rate. As the water level changes, the trap moves with it. During late winter and early spring, flow rates increase and the stream can reach depths of 10 to 12 feet. Booms allow the trap to work with different flow conditions.

In September 2010, ESG Incorporated, the company contracted to empty the trap for the city of Waycross, reported that a total of 73 cubic yards of trash had been emptied from the trap in less than five months of operation.

The Bandalong Litter Trap has been used for more than 15 years to capture and retain floating litter in waterways be-

fore it travels downstream. The key features of the system include: • Requires no mechanical assistance; uses only the natural current to passively collect floatables 24 hours a day, 365 days a year.

• Device will not cause flooding.

• No netting or fencing makes device safe for all aquatic wildlife.

• Does not interfere with recreation.

• Custom signs demonstrating anti-litter or clean water campaigns and sponsors raise awareness of the issue.

• Patented tidal gate prevents trash from exiting the trap.

• Site adaptable HDPE boom lengths.

• Effective in high and low flow rates.

• Attachable filtering media.

• Can be fitted with walkways and work platforms.

• Advanced anchoring and tethering.

• Solar-powered lights to increase visibility for boating safety.

To date, there are over 195 Bandalong Litter Traps installed worldwide. In 1995 it won an Australian EPA Clean Water Award.

Water & Wastewater Pipe

Fusible PVC pipe chosen for rural Québec water and sewer system expansion

W

hen the small agricultural municipality of Saint Paulin, Québec needed to connect several residents to the town’s sewer and drinking water systems for improved water quality, it wanted to ensure that it was done properly, quickly and cost-effectively.

Located in the historic Trois-Rivières area between the cities of Montréal and Québec, the municipality was also faced with the challenge of running the new sewer and water pipe system under the Rivière du Loup.

Recent water quality testing completed on the wells of several residents not connected to Saint Paulin’s existing sewer and water distribution system showed contamination in the drinking water. The source of the contamination was thought to be traditional septic systems.

Following testing, the Ministère des Affaires Municipales Québec required Saint Paulin to extend the water distribution and sewer system to those residents experiencing water quality problems.

With 80% funding provided by the Ministère, Saint Paulin set out to build the new system. The municipality first needed to decide between using traditional HDPE (high-density polyethylene) pipe, which

has long been installed in trenchless applications, or PVC (polyvinyl chloride), which has grown steadily in popularity throughout North America.

IPEX’s CIOD (cast-iron outside diameter) Fusible Brute™ PVC pipe features fully restrained joints with a tensile strength equal to that of the pipe. By combining the mechanical properties of PVC with a patent-pending butt fusion process, this pipe can be installed in long, continuous trenchless applications.

“At first, the municipality was hesitant to use PVC in the trenchless application.

We met with the engineering consultant, explained the differences between PVC and HDPE, showed testing and specification information, and demonstrated how Fusible PVC could offer more costeffective installation and long-term maintenance,” recalls Alain Charky, a manufacturer’s representative for IPEX. With HDPE, Saint Paulin would have to special order the pipe and use expensive transition fittings, due to its nonstandard outer and inner diameter that didn’t match the existing PVC water system. In addition, HDPE’s overall weight and material for the given pressure class would have resulted in a higher material and installation cost.

On the other hand, Fusible PVC would

allow for easy connections to the existing PVC water distribution and sewer system, via simple standard fittings, providing material consistency across the entire municipality.

In addition to ensuring reduced initial deployment costs, the total cost of ownership was also a concern for a small municipality like Saint Paulin. CIOD Fusible PVC pipe is easy to maintain over the life of the system, because all the accessories are readily available and can be deployed by the town's public works employees.

The Fusible PVC’s gasket-free joints and abrasion and scratch-resistant properties also ensure long-term reliability and reduced maintenance of the system.

Innovative fusion process For the forced sewer system, Saint Paulin used a total of 2,208 metres of 100 mm pressure-rated 165 psi CIOD Fusible Brute PVC pipe (DR25). For the potable drinking water system, they used a total of 2,611 metres of 150 mm pressurerated 235 psi CIOD Fusible Brute PVC pipe (DR18). For the majority of the system, the two pipes run side by side, separated by approximately one metre.

Fusible Brute PVC pipe is available in 12.2 metre lengths. To create longer pipe lengths the fusion process incorporates a proprietary PVC formulation and a combination of heat, pressure and time, using slightly modified standard industry fusion machines. The process is carried out by trained and licensed individuals, to ensure consistent, reliable fusion.

Fusion time with Fusible Brute PVC is comparable to other thermoplastic materials. The overall fusion of the Saint Paulin system was accomplished at an average of 19 joints per day. Fusion also can be performed in any temperature, as long as the pipe ends are maintained at a temperature above 4°C, and both the pipe ends and fusion machinery are sheltered from the elements.

For the Saint Paulin system, a remote field was used as the staging area and a tent was set up to shelter the fusion process from the elements. Under the tent, heat from the fusion machinery itself was enough to keep the pipe ends

The shelter of a tent, combined with the heat from the fusion machine, was enough to keep the pipe ends at the required temperature for fusing.

above 4°C. Once the fusion was complete, the lightweight, flexible lengths of pipe were then simply dragged from the staging area to the installation site.

Cost-effective, greener deployment For maximum cost-effectiveness and limited disturbance for residents, Saint Paulin specified a trenchless application using horizontal directional drilling (HDD) methods. HDD offers several key benefits, including faster installation, ability to place pipe under natural and manmade obstacles, and a greener, more environmentally-friendly approach. Using HDD eliminates the need to excavate a trench, which often requires tearing up asphalt and disturbing roadways, destroying the surrounding natural environment, and risking damage to other underground systems. These can require significant repair costs, after the pipe is installed.

It wasnâ&#x20AC;&#x2122;t just cost concerns that had Saint Paulin specifying HDD methods. In 1988, the village merged with the township of Hunterstown. This increased the number of residents to approximately 1,600. Today, Saint Paulin encompasses more than forty farms and 90 small and medium-sized businesses. The urban section of the original Hunterstown area is crossed by the Rivière du Loup, which the new water system needed to cross, in order to reach residents on the other side.

Only HDD could be used for this 84 metre section of the new water system.

side paths for the sewer and water pipes under the river. When the drilling head reached the other side, it was replaced with equipment, which pulled in the prefused lengths of pipe under the river. In addition to the 84-metre pull under the

river, the entire Saint Paulin project consisted of some 25 other pulls, with the longest one being 207 metres.

The full-strength butt fusion joints of the Fusible Brute PVC pipe gave Saint Paulin a greater pull force rating, which offers safer installation in tough conditions for HDD trenchless applications. In addition, the smaller outside diameter of the pipe means that the drilling equipment can make smaller bore holes which is faster and reduces the amount of drilling fluid required. In turn, this reduces the amount of fluid waste that has to be disposed of, making the project even more environmentally friendly.

After the new Saint Paulin system was installed, a one hour 125 psi pressure test was completed in accordance with ASTM D-638 methods on 1,800 metres of the 150 mm pipe used for the drinking water distribution system. The pipe passed with no make-up water required, indicating no system leakage.

WERF awardee seeks new ways to convert methane into green fuel The WERF Endowment for Innovation in Applied Water Quality Research presented its 10th Annual Paul L. Busch Award to Kartik Chandran, Ph.D. Chandran was selected for his research efforts to create an innovative wastewater treatment technology that could make affordable resource recovery a reality for plants of all sizes.

The Paul L. Busch award carries with it a $100,000 research grant that will aid Chandran and his team at Columbia University as they attempt to develop a new treatment technology that transforms plant-generated methane and carbon dioxide, potent greenhouse gases, into the green fuel, methanol. The technology could offer wastewater treatment plants a more cost-effective and environmentally friendly process for producing this alternative fuel and help them address one of their top challenges – the reduction of nitrogen in effluents.

Current methanol production is carried out largely through an expensive conversion process that chemically catalyzes the oxidation of methane gas. Chandran’s re-

search takes an alternative and more costeffective approach to generating methanol through the development of autotrophic microbial reactors. These reactors, which treatment plants can integrate into their normal biological treatment processes, convert the methane in digester gas straight to liquid methanol, avoiding purification and chemically catalyzed conversion.

Successful application of this technology could also hold significant benefits for other areas of wastewater treatment.

By integrating the microbial nitrogen and carbon cycles, it would be possible to si-

multaneously address nitrogen removal and greenhouse gas emissions by converting nitrogen to nitrite using ammonia oxidizing bacteria, and then channeling the methanol that these bacteria produce into biofuel or an external carbon source to enhance denitrification.

Consequently, the process could lower the overall greenhouse gas footprint of wastewater treatment plants by reducing both methane and carbon dioxide release, as well as recovering methanol. www.werf.org/PaulLBusch.

Water Reuse

Advanced treatment and reuse system developed for oilfield process water By Kevin Conroy

Construction progress showing excavation of equalization basin and bioreactor tanks.

R

ecent regulations and industrial water supply challenges in Trinidad and Tobago have led to construction of an innovative plant to treat oilfield produced wastewater. The 4,100 m3/day treatment system, developed by Golder Associates Ltd., will produce water suitable for industrial reuse and effluent that meets the country’s new regulations.

Influent characteristics of the wastewater, and the projected effluent quality and discharge criteria are presented in Table 1.

Treatment stages The treatment solutions include: 1. Oil-water separation – The water from oil production will contain some free oil and solids, which can be removed via gravity separation. A conventional corrugated plate interceptor (CPI) will produce three effluent streams: de-oiled wastewater, skimmed oil, and settled www.esemag.com

solids. De-oiled wastewater will flow by gravity to an equalization basin, settled solids will be transferred to a waste basin, and the skimmed oil will be returned to crude oil storage.

2. Equalization - The equalization basin is sized to provide two days of capacity at the design flow rate. Equalization will allow for operation of downstream systems in the event of influent flow interruption or short maintenance needs, retention of peak surge flows, and smoothing of “peaks and valleys” in contaminant concentrations. A lined in-ground basin is being constructed and outflow from it will be pumped for subsequent treatment.

3. Dissolved air flotation - Dissolved air flotation (DAF) will be used for removal of fine suspended solids and emulsified oil and grease not removed by the oilwater separator. DAF influent is treated with a coagulant and flocculant to provide effective separation. A high pressure air-

saturated recycle stream is then introduced. When the recycle stream mixes with incoming influent, micro bubbles are released and attach to the suspended solids and emulsified oil and grease.

Floatable solids form a blanket of sludge that is skimmed from the surface of the DAF unit and managed as a waste.

Heavier solids are trapped in a clarifier plate pack and removed as a settled sludge. Both DAF wastes are transferred to a waste basin for additional settling/ separation. DAF-treated effluent is pumped to the cooling tower prior to additional treatment.

4. Cooling - The temperature of the incoming produced water can be as high as 46oC. Cooling of the water to 27oC to 32oC is required prior to biotreatment. A set of six induced draft cooling towers, configured in three parallel trains of two units each, will be used to provide the necessary cooling. Cooling tower influJanuary 2011 | 29

ents typically require pretreatment to inhibit biogrowth and inorganic scale accumulation on the tower packing.

Benefits of biocides and anti-scalents were weighed against possible impacts on the subsequent biotreatment step. Cooling equipment was selected for its operational flexibility, ease of cleaning, and the ability to operate without the need for chemicals.

5. Biotreatment/settling - Aerobic fixed film biotreatment will be used to remove dissolved organic compounds measured as biochemical and chemical oxygen demand (BOD/COD). Bioreactor influent

is pumped from the DAF through the cooling tower to four immobilized cell bioreactors (ICBs). The ICB technology uses a patented high surface area packing material installed in four 250,000 gallon steel tanks as a packed bed. Two levels of fiberglass grating support the packing media.

Air will be introduced from a series of 150 HP centrifugal blowers, through a diffuser network installed below the grating. Metering pumps will add bionutrients (nitrogen and phosphate) based on treatment flow rate.

The immobilized cell bioreactor, orig-

inally commercialized by Honeywell International in the mid-1990s, is an advanced fixed-film bioreactor that provides a high rate of organics removal from wastewater. Also, it produces up to 75 percent less sludge than other biological treatment processes. Long biological solids retention time (up to 150 days) within the ICB system is the key to better process stability and lower waste solids formation. Because biological solids are not easily washed out of the bioreactors, they do not significantly contribute to total suspended solids (TSS) or sludge continued overleaf...

Water Reuse formation.

Excess bacterial biomass within the ICB becomes a food source for other higher life forms, which devour the lower forms of bacteria. All the bacteria devour new organics arriving in the influent waste stream. The net result is a greater overall conversion of soluble organic pollutants to carbon dioxide and water, and less conversion to biological solids.

The ICB system has several distinguishing features when compared with other fixed-film biological processes.

The heart of the technology is a mixture of two very different substrata for immobilization of the bioreactor biomass. One of the immobilizing substrata is highly reticulated polyurethane foam in the form of two-inch blocks. This component provides a high surface area for biomass colonization, up to 210 ft2 per ft3 of foam.

Once the bioreactor is fully colonized, these foam blocks are completely filled with biomass to a depth of at least oneinch. This gives the foam blocks a very high biomass density and, due to the highly immobilized nature of this biomass, a very long solids retention time.

ICB mixed media.

Incoming flow will be split between two bioreactors operated in parallel. Flow from the two lead bioreactors will be recombined and flow through two additional bioreactors operated in series.

Biotreated effluent will flow by gravity to

a settling basin for removal of any excess biosolids.

The ICB technology was tested and proven using a bench pilot system.

Bionutrient requirements, pH adjustment requirements, and hydraulic retention time were determined during this testing and used as design inputs for the fullscale system. The bench testing program demonstrated essentially complete BOD removal and consistent reduction of COD to <240 mg/L. It has been concluded that the balance of the COD is refractory and not biodegradable, and would not be bioavailable in a receiving water environment.

6. Prefiltration/reverse osmosis - The final step in the process is reverse osmosis which removes dissolved solids to concentrations acceptable for boiler system reuse. A vendor-packaged system, including prefiltration, reverse osmosis and ancillary equipment, was procured to simplify system integration.

Prefiltration using three gravity sand filters in parallel will remove fine suspended solids that do not settle in the settling basin. The sand filters will

Jan2011_ES&E_D4_ES&E 11-02-02 2:07 AM Page 32

Water Reuse continuously backwash at a flow rate of about five percent of the forward flow.

Backwash water will be collected and transferred to the settling basin.

Reverse osmosis systems are typically protected with elaborate pretreatment systems to maximize system operation between membrane cleaning cycles. The design philosophy for this part of the system is minimal pretreatment based on a tradeoff between pretreatment complexity and membrane cleaning/maintenance.

The reverse osmosis system consists of three parallel trains of membrane modules, with two on-line at all times.

A relatively low target reverse osmosis recovery of 50 percent is used as a design criteria consistent with projected performance due to elevated silica levels in the incoming wastewater. The concentration of COD in the brine will be approximately double the projected biotreated effluent concentration of 240 mg/L. While this will exceed the near shore discharge limit of 250 mg/L, the actual mass load discharged to the ocean is no different than if the full biotreated flow (without reverse osmosis) were to be

discharged. Consideration has been given in the permitting process to a mass load standard rather than an end-of-pipe numerical concentration criteria.

7. Effluent storage/transfer - Reverse

Reverse osmosis systems are typically protected with elaborate pretreatment systems to maximize system operation between membrane cleaning cycles. osmosis permeate will be held in a 283 m3 tank, prior to transfer to the point of industrial reuse. Final pH adjustment of the treated water will be made prior to

the transfer. Real-time chemical analyzers will be used to monitor conductivity, COD, and oil and grease, and will automatically divert off-specification water back to the equalization basin. Reverse osmosis brine will also be stored prior to transfer for near shore ocean discharge.

Conclusion This advanced treatment system will provide several important benefits. Inland discharge of minimally-treated produced water will be eliminated, reducing potential environmental and public health concerns. The end user of the recycled water will gain a new source of industrial water with a resulting decrease in demand for fresh water.

The success of Trinidad and Tobago’s first foray into treatment of produced water could lead to additional facilities in other oil field locations, expanding the economic and environmental benefits of water reuse.

Ecosystem Management

Developing a fish habitat banking program in Canada By Paul Patrick, Kyle Hunt, Marlo Spence Lair and Michael Connell

T

he concept of habitat banking was first introduced in the United States in the mid-1980s to compensate for losses of wetland habitat to new development.

Since the introduction of habitat banking for wetlands (termed “mitigation banking” in the US), the practice, known as conservation banking, has expanded to include compensation for losses of species at risk habitat.

The first habitat bank in Canada was developed in 1993 in the North Fraser Harbour in Vancouver. In recent years, various other countries have begun developing similar habitat banking programs and numerous habitat banks are now operational internationally.

Canada’s Fisheries Act, administered

by Fisheries and Oceans Canada (DFO), provides the authority to regulate the impact of development projects on fish habitat in all Canadian fresh and marine fisheries waters.

Section 34 of the Act defines fish habitat as “spawning grounds, and nursery, rearing, food supply and migration areas on which fish depend directly or indirectly in order to carry out their life processes.” Section 35 (1) states that “no person shall carry on any work or undertaking that results in the harmful alteration, disruption or destruction of fish habitat” (commonly referred to as a HADD). Section 35 (2) provides that “no person contravenes subsection (1) by causing the alteration, disruption or destruction of fish habitat by any means or under any conditions authorized by the Minister or under regulations made by the Governor in Council under this Act.” Prior to issuing a subsection 35 (2) authorization, DFO officials must ensure that an environmental assessment is conducted under the Canadian Environmental Assessment Act or other processes in the North, and that the duty to consult Aboriginal groups and, if applicable, the requirements of the Species at Risk Act are met.

The Fishery General Regulations specify the form for applying for and issuing an authorization, but do not provide 34 | January 2011

additional guidance. As a result, guidance on the issuance of subsection 35 (2) authorizations is to be found in a policy framework, beginning with the 1986 Policy for the Management of Fish Habitat.

This policy establishes that impacts of human activities on fish habitat will be governed by the principle of “no net loss of productive capacity of habitats” (NNL).

Applying the no net loss principle The habitat policy states that the conservation of fish habitat will be guided by the NNL principle. This principle is intended to guide departmental officials in balancing unavoidable losses of fish habitat with replacement of fish habitat on a project-by-project basis. Thus, reductions to Canada’s fisheries resources, due to habitat loss or damage, can be prevented.

According to the habitat policy, the NNL principle should not be interpreted as a statutory requirement to be met at all

costs and in all circumstances. It further states that fisheries management objectives and plans, either on a fish stock-specific or geographic area basis, will be the major consideration for deciding where to apply this guiding principle, and, also, what offsetting proposals would be acceptable to achieve no net loss.

The habitat policy indicates that the NNL principle is to be applied to proposed works and undertakings and is not retroactively applied to approved or completed projects.

The habitat policy outlines procedures to apply the NNL principle. The procedures define the hierarchy of preferences to achieve a no net loss of productive capacity, where the fisheries resources and its supporting habitat are put at risk by a proposed development project. The preference is to avoid any loss or harm at the site of the proposed project site through redesign, use of alternative location or

Ecosystem Management mitigation techniques.

Only after it proves impossible or impractical to maintain the same level of productive capacity of fish habitat would compensation measures be explored to offset loss or harm to fish habitat resulting from the project.

Compensation is defined as: “The replacement of natural habitat, increase in the productivity of existing habitat, or maintenance of fish production by artificial means in circumstances dictated by social and economic conditions, where mitigation techniques and other measures are not adequate to maintain habitats for Canada’s fisheries resources.”

The costs associated with defining and implementing compensation measures are the responsibility of the project proponent. The procedures also state that DFO will apply the NNL guiding principle to achieve its conservation goal using existing project regulatory review and environmental assessment processes in accordance with six steps. These include notification, examination, public consultation, decision, audit and enforcement.

The decision step also includes guidance on appeals for persons who believe they have been aggrieved by a decision made by departmental staff.

Building on the principles and procedures of the habitat policy, the Habitat Compensation Guide was published in 2002. It provides guidance in applying fair and consistent decisions on compensation, in order to achieve a no net loss of productive capacity of fish habitat con-

sistent with the habitat policy, while recognizing the need for local discretion.

The guide provides further direction on the hierarchy of compensation options, including exceptions to the compensation hierarchy. It includes guidance on determining the amount of compensation required; monitoring, enforcement, financial security, restoration of orphaned sites; habitat banking; measures of last resort (artificial propagation, deferred compensation and restoration of contaminated sites); and authorizing compensation.

As part of its cycle for evaluating existing policies, DFO is reviewing and revising the Habitat Compensation Guide to address implementation issues and consider new thinking about fish habitat compensation. An important element of the review will be to consider development and experiences with the concept of fish habitat banking and to develop further guidance on its application as an integral part of a new operational policy on fish habitat compensation.

The habitat compensation option most often employed in Canada is the creation of in-kind habitat following the authorization of a HADD. As outlined in the habitat policy, this typically occurs on a project-by-project basis. Developers are required to create or increase the productive capacity of fish habitat either on- or off-site through a number of potential management interventions such as stream restoration, controlling invasive species, or removing and replacing man-made physical barriers such as

dykes or culverts.

Habitat banking is a compensation tool that holds strong potential to provide more predictable and effective outcomes from fish habitat compensation in Canada. Although habitat banks have been established in several provinces (Nova Scotia, Québec, Manitoba, Alberta and British Columbia), the practice is not widely used as a compensation option for HADD authorizations.

The Habitat Compensation Guide identifies habitat banking as one option for fish habitat compensation to offset a HADD authorization. The guide simply defines habitat banking as: “The completion of compensation prior to a subsection 35(2) Authorization being issued where a proponent creates or improves habitat for future use as compensation.”

Although the Habitat Compensation Guide describes some elements of habitat banking and provides a basic definition, Canada lacks a comprehensive definition of habitat banking.

SENES Consultants and High Park Group (HPG) are currently working on an industry funded initiative with the purpose of establishing a rationale and path forward for the advancement of habitat banking as a key tool in compensating for development impacts in Canada.

On-site power generation protects water supply for Ajax, Ontario

By Mohamed Morsy

T

he Town of Ajax, Ontario, on the north shore of Lake Ontario, was named for the HMS Ajax, a Royal Navy cruiser that gained fame in several key naval battles of World War II. The ship, in turn, was named for the figure from ancient Greek mythology, famous for his strength and courage in battle. The town grew up around a defense plant established in 1941 to make shells for the war effort. Today, Ajax boasts a population of over 90,000.

The Ajax Water Supply Plant treats and distributes water for the Town of Ajax and the nearby City of Pickering. The operations staff of 25 manages two other treatment plants that supply the City of Oshawa and, through a remote system, the Town of Whitby. The staff also manages a dozen pumping stations, reservoirs and elevated tanks in the region.

The Ajax plant requires approximately 2 megawatts (MW) of continuous power during peak water demand to supply the 150,000 customers it serves. Although local utility power is reliable, standby power generators are mandated by the Ontario Ministry of the Environment (MOE).

Water hammer and other problems Like many water treatment plants, Ajax has reservoirs and elevated storage for backup water supply. However, when the utility power goes out, problems can result in the plant and system. Peter Cameron, District Supervisor of Plant Operations, cited examples: “Water hammer occurs, caused by the flow stoppage and reversal. This can damage water mains and result in customer complaints due to disrupted service. At the control center, you get a tremendous influx of alarms, which can distract attention from conditions that require more immediate action. The entire plant can be disrupted.”

Importance of being parallel To avoid these potential problems, Ajax Water Supply staff selected Cummins Power Generation on the basis of its product design, integrated paralleling Environmental Science & Engineering Magazine

switchgear and the ability to provide the entire package exactly as specified.

Cummins Ontario delivered one 350 kW and two 1500 kW generator sets, along with automatic transfer switches and paralleling switchgear. These digital systems parallel and synchronize the generator sets with each other and with the utility. There are paralleling controls mounted on the generator sets, as well as a separate digital master control unit for supervisory functions.

Peter Cameron said: “With the complexity of this plant, being able to provide continuous service is a tremendous advantage. If we had standard transfer switches, with blips and time delays from power going off and on, it would complicate operations. This paralleling system has been a real benefit.”

For security reasons, the managers at the Ajax facility wanted the generator sets to provide read-only monitoring in the control room. This precaution prevents inadvertent changes or accidental command execution during emergencies.

Possible peak-shaving application The Ajax plant is designed to allow for twice its current capacity, including room for more generator sets and fuel storage.

Beyond being prepared for future expansion, the power generation system is also ready for peak-shaving and other nonstandby applications, at least between the hours of 7 a.m. and 7 p.m.

Minimizing environmental damage from transportation projects

By Dean L. Groves

M

odern transportation projects, such as highways, create a number of positive outcomes, from enhancing the connections between existing communities, to advancing future development and economic growth. At the same time, the negative impacts that a transportation project can have, particularly on the environment, are extremely important and cannot be overlooked.

When new corridors are cleared for transportation projects, they often affect massive tracts of land, removing these acres from other uses, including passive recreation. Also, natural resource areas, including meadows, wetlands and forests, are sometimes lost, greatly reducing wildlife habitat for fish and game, and rare and endangered species.

And, of course, there is the issue of pollution. Vehicle emissions negatively affect outdoor and indoor air quality. The potential for water and land pollution is also significant, as chemicals and particles released by vehicles, through runoff from impervious surfaces, can degrade the quality of soil, lakes and streams.

Many would argue that our overall quality of life declines as more of our 38 | January 2011

open spaces are given over to development projects such as an office park or retail development. Therefore, it is imperative that today’s transportation designers and planners balance the need to improve roadways and other transportation facilities with the need to protect and maintain environmental resources. Such effective planning will ensure that today’s transportation investments remain one of society’s most important contributors to environmental enhancement.

Pollutants and water quality A highway’s surface water runoff and drainage systems are quite different from those normally featured in a site development. For the most part, the amount of contaminants carried by the surface water runoff increases with the volume of daily traffic. Salting and sanding practices leave residual concentrations of chloride, sodium and calcium on a roadway surface. Meanwhile, vehicles drop oil, grease, rust, hydrocarbons, rubber particles and other solid materials onto the pavement at higher concentrations than typically experienced with surface parking areas in a shopping mall.

Today’s highway projects usually feature stormwater management design ele-

ments, such as bioswales and filter strips, that address runoff of pollutants and water quality issues.

Bioswales are vegetated stormwater collection areas strategically placed within medians or parallel to a road.

Stormwater captured in the bioswale is collected and slowly treated with specially engineered soils and plants before it infiltrates the ground. Filter strips are vegetated areas that slow stormwater runoff velocities, filter out floating particulates (such as sediment and other pollutants) and provide infiltration into underlying soils.

A wetland’s place in the natural world is a crucial one; it serves many functions, including stormwater retention and waterquality improvement. Wetland mitigation is another way to address stormwater runoff issues along highway corridors. It often refers to the act of replacing the function and value of an affected wetland by creating, restoring or enhancing a wetland in another suitable location that includes consideration of groundwater, soils, plantings and other features.

Finally, designers and planners are making use of filtering systems that include features such as a sedimentation

Environmental Protection area to retain large particles, and a filter chamber to remove pollutants. Detention and retention ponds, which temporarily store stormwater runoff while containing suspended solids and other contaminants, continue to be important elements of effective stormwater control and management systems. These help reduce pollutant loadings on downstream receiving waters.

Improving indoor and outdoor air quality Transportation planners are also taking steps to reduce the negative effects of construction projects on air quality.

Emissions from construction vehicles, equipment and generators include carbon dioxide, as well as fine particulate-matter pollution, especially from diesel equipment, which contributes to asthma and allergies and is listed as a probable carcinogen. In addition, vehicles create dust from paved and unpaved roads and further affect air quality when idling in heavy construction zones.

Increasingly, construction documents are requiring the use of diesel particulate filters on all diesel-powered vehicles.

These filters are positioned in the exhaust streams of diesel vehicles to collect and store particulate emissions. Construction equipment that utilizes cleaner-burning diesel fuels is also becoming popular in the quest to improve air quality.

Other methods include: â&#x20AC;˘ Establishing separate generator sites and truck-staging zones for vehicles waiting to load and unload materials. Such zones are located where diesel emissions have the least impact on abutters, the general public and particularly sensitive receptors (hospitals, schools, housing for the elderly, etc.). â&#x20AC;˘ Prohibiting vehicles from leaving construction sites with mud and dirt on their bodies or wheels, a prime contributor to dust. This is done by temporary wheelwash stations. â&#x20AC;˘ Further controlling dust through the use of wet suppression and soil stabilizers.

Wet suppression calls for the application of water or a wetting agent in solution with water. Soil stabilizers are environmentally safe, water-soluble chemicals that increase compaction and soil density. â&#x20AC;˘ Providing wind screens, which are often attached to construction fences, and wooden wind barriers in locations where they are effective in minimizing wind www.esemag.com

erosion and the spread of dust. Also, placing tarps on stockpiles, secured with sandbags or an equivalent method.

Effective planning for transportation projects looks beyond concrete and asphalt. It involves identifying the environmental characteristics of the area affected by a project; creating solutions to avoid and/or minimize direct impacts on valuable resources; developing thoughtful actions to mitigate and enhance existing conditions, where practical; and control-

ling and managing the construction process in an environmentally friendly fashion.

When project development truly succeeds, the resulting projects satisfy the transportation objectives, while also enhancing complementary transportation modes and quality of life.

Corrosion

Protecting concrete and rebar in wastewater treatment facilities

By Ivan Razl and Alexandru Cotofan

R

einforced concrete is typically used in the construction of municipal wastewater treatment facilities and associated structures such as sewer systems, manholes and lift (pumping) stations. In most cases, it is left unprotected and exposed to wastewater.

Properly constructed structures, using good-quality concrete and sufficient cover of the reinforcing steel, last a long time. There will not be much deterioration even after 40 to 50 years. But service life is considerably shorter with poorquality concrete, low concrete cover on the reinforcing steel, and inferior construction. Major restoration of these structures is expensive.

Designing wastewater structures for a service life of 100 years or more, which is double their usual service life, will reduce restoration costs. In order to do this, we need to be concerned not just with protection of the concrete and waterproofing, but also protection of the reinforcing steel.

below the water line over time.

Above the water line, reduction in the pH of concrete will also take place, but for a different reason. Sulphates (SO42-) contained in wastewater are converted by microbiological activity to hydrogen sulphide gas, which escapes and, in the presence of bacteria and oxygen, is converted by microbiological activity to sulphuric acid on the surface of the concrete. The sulphuric acid attacks and penetrates the concrete and reduces its pH. In addition to acid attack, the formation of water-soluble gypsum and expansive ettringite also contribute to concrete deterioration.

PH reduction of the concrete de-passivates the reinforcing steel, resulting in corrosion, expansion of corrosion products, concrete cracking, spalling and even structural failure as shown in Figure 1.

Gemite Products Inc., through its subsidiary Gemite Romania, has been involved in the restoration of a number of wastewater treatment facilities in Romania. Extensive non-destructive investigation of these structures was carried out,

Figure 1. Structural failure in Slovakia.

Figure 2. Botosani wastewater facility.

Designing wastewater structures for a service life of 100 years or more, which is double their usual service life, will reduce restoration costs.

Reinforcing steel embedded in concrete is protected against corrosion by the high pH of concrete. This is initially around 13.8 and about 12 to 13 in the long term, which provides a chemical passivation of the reinforcing steel.

To protect the steel, we need to prevent the reduction of the pH in the long term.

Wastewater contains a number of acidic materials, such as uric, acetic and lactic acids and other chemicals such as sulphates, phosphates and chlorides. Even though the pH of wastewater is typically close to 7, the presence of acids can cause a reduction in the pH of the concrete 40 | January 2011

evaluating the rate of corrosion of the reinforcing steel, half-cell potential measurements, concrete resistance, compressive strength, concrete cover, carbonation depth, hydraulic permeability, and measurement of the pH profile throughout the wall of the clarifiers.

Figure 2 shows the typical state of a reinforced concrete wastewater treatment facility in Botosani, Romania, after approximately 50 years of service life. This high level of deterioration is not normally exhibited by similar structures in Canada.

In Botosani, it was mainly due to poorquality construction, specifically low

Corrosion cover on the reinforcing steel and, in some areas, low concrete quality and lack of freeze/thaw resistance standards (air entrainment) at the time of construction.

Figure 3 shows coring of the clarifier wall. Three cores were taken at this structure for measurement and the pH profile was determined using pH indicating solution. Table 1 shows the relationship between the colour of the concrete after application of the pH indicator and the pH of the concrete. The structure was 45 years old at the time of investigation, and the compressive strength varied from 20 to 26 MPa. Figure 4 shows the cores after application of the pH indicating solution. The pH variation as a function of depth is shown in Table 1.

The results are the average of three cores. They clearly indicate that acidic conditions exist below the water line of the clarifier, which in time reduce the pH of concrete, resulting in loss of steel passivation and corrosion of the reinforcing steel. There are no measurements from digesters above the water line. But, it is safe to assume they will be similar, if not

worse, since the sulphuric acid formed by the microbiological conversion of hydrogen sulphide is considerably stronger when compared with acidic materials below the water line.

Using polymer coatings One approach to the protection of concrete in wastewater treatment facilities is the application of polymer coatings such as epoxies, urethanes or polyureas to the surface of the concrete.

While these materials exhibit excellent chemical resistance, they also have many disadvantages when applied to concrete exposed to a wet environment. They are sensitive to moisture in concrete during application and, as effective vapour barriers, are not breathable.

It is difficult to create a polymer layer applied to concrete that is completely free of “pin holes” and cracks. Water penetrates through those imperfections and capillary pressures at the interface debond the polymer coating. This process occurs in any structure where concrete is coated with a polymer in a continuously wet environment.

Even when there is complete cover

with the coating and no pin holes, debonding may still occur due to water vapour transfer from behind the coating and water condensation at the coating concrete interface. The capillary pressures are high and could cause de-bonding of the coating from the concrete surface.

Another solution for the protection of concrete structures in wastewater treatment environments is to use polymermodified cement coatings such as Cem-Kote Flex ST and Cem-Kote Flex CR. The high level of polymer modification provides excellent chemical resistance and flexibility, while the cement content makes these coatings “breathable,” allowing water evaporation and the release of possible capillary pressures at the interface.

The Portland cement-based Flex ST product is used in all applications with minimum concentrations of hydrogen sulphide, while Flex CR is used where higher concentrations of hydrogen sulphide are expected, such as roofed clarifiers, digesters, pumping stations, sewers continued overleaf...

Both Flex ST and CR are easy to apply, and tools and equipment can be cleaned simply by washing with water.

They are two-component materials, consisting of dry bagged powders and a liq-

uid polymer additive supplied in a plastic container. The two components are mixed on-site using a conventional electric paddle mixer, or mortar mixer, and applied in two coats by brushing or spraying to a total thickness of 1.6 to 2 mm. In new construction, a high pressure wash is sufficient to clean existing concrete.

Smaller â&#x20AC;&#x153;bug-holesâ&#x20AC;? are coated over with Flex ST/CR, and larger ones are

pre-filled with the same material mixed with less of the liquid component to obtain a trowel consistency. Any shrinkage cracks are treated with Reinforcing Fabric NW, which provides waterproofing even if the crack bridging capacity of Flex ST/CR is exceeded. Several types of equipment, including peristaltic and positive displacement pumps may be used for the spraying.

WA ST for wet shotcrete process application, are applied in thicknesses varying from 1 to 5 cm, depending on the degree of deterioration. A leveling layer is required to repair the surface and provide a smooth surface to minimize pin holes in the application.

Spray-Con WS ST was also a part of the testing program in Russia and exhibited good resistance to the microbiologically induced corrosion (MIC) environment. These fibre-reinforced materials are insensitive to the presence of moisture in the concrete substrate and the fibre reinforcement provides a higher toughness and greater degree of substrate crack bridging than non-reinforced materials.

Protecting metal parts Wastewater facilities, manholes, and sewer systems also contain metal parts that require corrosion protection. Gemite has been successfully using a cementbased corrosion-protective coating, FibrePrime, which does not require the very clean â&#x20AC;&#x153;white metalâ&#x20AC;? surface and requires only loose rust removal. It is completely

insensitive even to surface moisture present on the metal parts.

For additional protection to MIC, Cem-Kote Flex CR can be applied over Fibre-Prime. The advantages of FibrePrime are also important in the corrosion protection of exposed reinforcing steel in the restoration of reinforced concrete structures.

Figure 8 shows an early project in Bedford, Nova Scotia. The severely cracked concrete tank was first coated with a 12-mm layer of wet shotcrete applied, fibre-reinforced mortar Gem-Crete HDO and coated with two coats of CemKote Flex ST. The project was carried out in 1993 and an investigation last year showed that the repair and crack sealing are functioning very well.

An example of Cem-Kote Flex CR used in the construction of a wastewater treatment facility in Bracebridge, Ontario, is shown in Figure 9.

New initiative to provide environmental sector opportunities for Aboriginals

W

ith the recent downturn in the economy, it has been difficult for a number of Canadians to find work.

Aboriginal people, however, are among a few select groups that are finding it especially hard.

In a study conducted by Statistics

Canada, between 2008 and 2009 the average employment rate fell faster for off-reserve Aboriginal people than for non-Aboriginal people. As a result, the gap in employment rates between the two groups widened from 3.5 percentage points in 2008 to 4.8 in 2009.

In response, a number of government

and private agencies have been working together on projects that will remedy the situation. There are now 34 federal departments and private agencies currently involved in Aboriginal and northern programs and services. The most recent agency is the Contaminates Remediation Training Organization of Canada (CRTOC).

The CRTOC was created in 2009, when a consortium of Aboriginal organizations and businesses, post-secondary institutions, private sector businesses, and the environmental sector council of ECO Canada, came together to help increase employment within the Aboriginal population through environmental training.

Funded in part by the Aboriginal Skills and Employment Partnership program (ASEP), through Human Resources and Skills Development Canada (HRSDC), CRTOC set out to promote long-term employment of Aboriginal residents in the contaminated sites remediation sector.

With over 18,000 sites listed on the Federal Contaminated Sites Inventory and only a few training facilities, with limited resources, the CRTOC was a well-received resource for northern comPhoto Abandoned DEW Line stations like this one in Northern Canada often need extensive site remediation work.

The Distant Early Warning Line was a system of radar stations built in the far northern Arctic region of Canada during the Cold War.

Water Supply

A greener way to rehabilitate water pipes

By Sadesh Mahalingam

The liner is impregnated on-site and pulled into place by a winch.

A

lthough the dig-and-replace method for installing underground utilities has been widely accepted for decades, with growing awareness of global warming and the need to reduce airborne emissions, trenchless methods are becoming more common, particularly in congested environments. The cured-inplace-pipe (CIPP) methodology offers a number of environmental and other advantages for water main rehabilitation.

Deterioration of water main pipes is a major concern. Most structures built prior to the early 1970s had water main lines composed of predominantly cast or ductile iron. With these materials, tuberculation takes place over time, causing the pipe to lose some or all of its structural integrity.

City water pressure may be anywhere from 30 to 120 psi, so even a small crack in the water main can lead to a leak and eventually a break. Repairing a burst pipe will cost money, but water damage resulting from uncontrolled leaks can easily cost more. Water main breaks are, of course, more common in the winter season, because of freezing.

Aqua Pipeâ&#x201E;˘ from Fer-Pal Construc46 | January 2011

tion is a CIPP technology that has been used successfully to rehabilitate damaged cast iron, ductile iron and asbestos cement pipes, with diameters ranging from 100 to 300 mm.

The liner is made up of two concentric, tubular, plain-weave polyester jackets with the inner jacket bonded onto a polyurethane elastomer. Jackets are impregnated with a curable polymeric resin.

The resulting composite material liner has mechanical properties exceeding ASTM F1216 and ASTM F1743 recommendations for fully-deteriorated pipe.

Prior to insertion of the Aqua Pipe liner, the host conduit must be cleaned to remove accumulated scale and rust (tuberculation), and service connections located and mapped. A mechanical robot equipped with a camera is inserted into the rehabilitated conduit and activated by an operator using a remote control and television unit. The liner is impregnated on-site and pulled into place by a winch, before being formed using sponges and pressurized water.

As the temperature gradually increases to the desired level, the epoxy cures, creating a solid composite with the liner. The robot is then equipped with

a drilling tool that allows an operator to drill a hole in the liner at the precise location of the connection. After opening connections, the rehabilitated pipe is flush-cleaned and chlorinated. Service is then restored.

Benefits of CIPP technology Going trenchless can cut the cost of rehabilitating pipes in half, including temporary restoration, valves, fire hydrants and other miscellaneous replacements.

Customers also know they are doing their part to preserve the environment.

A carbon footprint study was conducted last year at Fer-Palâ&#x20AC;&#x2122;s Yorkville site in central Toronto, using a calculator offered by the North American Society for Trenchless Technology. It allows planners to estimate carbon emissions from traditional open-cut excavations and various trenchless methodologies, based on the machinery required to remove, dispose of and replace soil, as well as traffic disruptions.

The project in Yorkville consisted of structurally rehabilitating 2,500 m of 150mm-diameter pipe. A typical project of such length would take 16 weeks of opencut technology compared to between five and six weeks using CIPP technology.

What was remarkable, though, was the fact that most local businesses were able to remain open throughout the entire project, in an area that is heavily populated with both vehicles and pedestrians. The City of Toronto even had the luxury of asking Fer-Pal to leave the site during the Toronto International Film Festival and to return to work upon its conclusion.

Looking back on the project, a total carbon dioxide emission of 250 tonnes would probably have been recorded if an open-cut methodology had been selected. This would have been broken down into: pollution due to traffic - 24 tonnes; trucks required to ferry dirt back and forth - 99 tonnes; machines - 54 tonnes; material footprint - 72 tonnes.

Using CIPP methodology, an estimated 5 tonnes of greenhouse gas were emitted over the length of the project - a saving of 98%.

Trenchless technology has other environmental benefits, as roads do not have to be torn up. It can also be used to reinstate or upgrade water services that run from city streets to homes, without the need to dig up lawns and cut down trees. The dig-and-replace method requires disposal of the old iron pipe, whereas CIPP technology keeps the old pipe, thus reducing waste.

Besides the environmental advantages, structurally rehabilitated pipe provides an increase in hydraulic carrying capacity, is corrosion-proof, and has a www.esemag.com

life expectancy of 50 years or more. The liner can negotiate through multiple bends, which facilitates the rehabilitation of water mains underneath creeks, highways, railroads and bridges.

The probability of a water main break is close to zero since the compos-

ite liner is known to withstand working pressures up to 150 psi.

Wastewater Treatment

Stress testing the Simcoe WWTP for higher rated capacity By Harpreet Rai

T

he Simcoe Wastewater Treatment Plant was originally commissioned in the 1960s and upgraded in the mid â&#x20AC;&#x2122;70s. At the existing plant site, the facilities can be generally described as an activated sludge system with two separate process trains, called Plant 1 and Plant 2, with each plant capable of operating independently of the other. They have a common headworks and tertiary treatment facility.

Plant 1, built in 1962, is the older of the two plants, treating approximately 2,600 m3/day. Plant 2 was completed in 1979 to meet future development needs.

The two plants operated in parallel until Plant 1 was closed in 1996 because of its poor condition. Plant 2, with a design capacity of 12,729 m3/d, operated alone until 2009.

In the Norfolk Water and Wastewater Master Plan (2006) it was established that the capacity of the Simcoe WWTP needed to be increased from the existing 12,729 m3/d to 15,400 m3/d to meet the development requirements for the next 20 years. A Class Environmental Assessment (EA) for capacity upgrade was completed in 2008, which recommended rehabilitation of Plant 1 to achieve the required capacity. Plant 1 was then refurbished and recommissioned and has since been running in conjunction with Plant 2.

Further, as part of the Class EA, an assimilative capacity study of the Lynn River was conducted in 2008, in order to predict the potential impact of the increased plant effluent flows on the quality of the river water. The study concluded that the plant would not be detrimental to the water quality in the river, provided the effluent loadings at the proposed rated capacity were maintained at their existing level.

This translated into not only stricter effluent criteria for carbonaceous biochemical oxygen demand (cBOD5), total suspended solids (TSS) and total phosphorus (TP) in comparison to the old Certificate of Approval, but also established limits on total ammonia nitrogen in the effluent.

Since the plant had historically been 48 | January 2011

operated at relatively less stringent effluent criteria for cBOD5, TSS and TP, and with no requirement for nitrification, Norfolk County was asked by the Ministry of the Environment (MOE) to conduct a stress test of the WWTP to confirm that it could handle the increased loadings, while meeting the more stringent effluent criteria at the proposed flow.

Stress-test work plan A work plan for stress testing was developed based on the MOEâ&#x20AC;&#x2122;s Guidance Manual for Sewage Treatment Plant Process Audits, and on the proposed effluent quality parameters presented in the Lynn River assimilative capacity study.

The stress test work plan was prepared by R.V. Anderson Associates and reviewed by the MOE. Calibrated BioWin models for Plant 1 and Plant 2 were developed from the historical operational and performance data for both plants.

Subsequently, the normal operating conditions of the plants were identified, and improvements in the operating strategy, with respect to consistent nitrification, were recommended, based on the calibrated BioWin model.

A test protocol was developed with plant operations staff to outline the program and solicit suggestions for improvement to overcome any potential obstacles.

The recommended changes in the process were executed by operating staff before starting the stress test.

Each train was stress tested for a period of six weeks during different periods of the year. Plant 1 was tested from March to April 2010 (winter), while Plant 2 was tested from May to August 2010 (summer).

The first four weeks of stress testing for each plant consisted of steady-state operation in which the tested train was run at its respective target average day flows (Table 1) and subjected to diurnal variations proportional to the overall WWTP influent variations.

During the next two weeks of the stress test, each train was run at the same operating conditions as in steady state, except that it was also subjected to the target hydraulic peak (Table 1) by manually increasing the flow to the train for over one hour each day during these two weeks.

Plant operation was closely monitored during the entire stress test period. The recorded parameters included influent and effluent flows, return activated sludge (RAS) and waste activated sludge (WAS) flows, mixed liquor TSS and RAS TSS, and sludge volume index (SVI), on a daily basis, five days a week.

The performance of each train was based on regular monitoring of 24-hour composite samples of the plant influent and secondary effluent five days a week.

In the case of Plant 2, the final effluent, following disinfection and tertiary filtra-

tion, was also monitored, in addition to the influent and secondary effluent.

Plant 2 is made up of four trains, with each train consisting of a primary clarifier, an aeration tank and secondary clarifier. Since the average raw sewage

coming to the overall plant during stress testing of Plant 2 was 6,400 m3/d, Plant 1 and two trains of Plant 2 were shut down in order to create effective stress loads.

ing the hydraulic peak testing phase were achieved by shutting down one of the two operating trains in Plant 2 for a period of more than one hour every day during this phase of testing.

The effluent limits and objectives for the increased rated capacity of the Simcoe WWTP are given in Table 2.

Performance of Plant 1 The calibrated BioWin model was generated from actual field operating and performance data for Plant 1, which was used to predict the performance of the plant under a minimum winter temperature of 10°C and average summer temperature of 16°C, in order to check the

plant’s ability to meet the effluent criteria of ammonia nitrogen (NH3-N) under these conditions.

The discrepancy in the actual and modeled effluent NH3-N values is because the actual field data includes some inconsistently high effluent NH3-N values on certain days, caused by shock loads received at the plant during stress testing, whereas the modeled performance is based on consistent and steady loads with no fluctuations in influent loadings and, therefore, consistently low effluent NH3-N. Average secondary effluent characteristics from Plant 1 for the five weeks of stress testing are well below effluent limits for all parameters, including BOD5, TSS, NH3-N, TP and CFU (colony forming units). Further, the average effluent NH3-N even meets the winter objective of 3.0 mg/L, even though the plant was operated at an average flow of 3,276 m3/d, or 23% more than the required stress flow of 2,671 m3/d.

The simulation shows that Plant 1 has enough capacity to handle the required stress loads, as secondary effluent meets

Average secondary effluent BOD5 and TP from Plant 2 are well below the effluent limits. Tertiary filters captured the solids in secondary effluent, bringing the final effluent TSS to 3 mg/L which is below the effluent objective for TSS. Average effluent NH3-N of 1.25 mg/L was observed to be higher than the effluent limit of 1.0 mg/L for summer. The main reason for this was the operating flow of 14,600 m3/d, which is 15% higher than the target stress test flow of 12,729 m3/d for Plant 2.

On the other hand, simulated performance of Plant 2 at 12,729 m3/d showed that the plant can be operated at a higher SRT of 10d at these loadings, thereby achieving effluent NH3-N of 0.49

mg/L, which is 0.31 mg/L lower than the 0.8 mg/L achieved at 14,600 m3/d. Based on this observation, average effluent NH3-N concentration under field conditions would be 0.94 mg/L (lower by 0.31 mg/L) at 12,729 m3/d, compared to 1.25 mg/L observed at 14,600 m3/d. Therefore, it will meet the effluent limit for summer conditions.

The simulation also shows that Plant 2 has enough capacity to handle the required stress loads under winter conditions, as secondary effluent from Plant 2 meets effluent limits for all parameters, including cBOD5, TSS, NH3-N and TP, at 10°C. The capacities of the sludge handling facilities, chlorine contact chamber and tertiary disc filters were analyzed theoretically and were shown to be adequate to handle the proposed rated flow of 15,400 m3/d.

Lessons learned Operating conditions, including influent flows and characteristics during field stress testing, may differ widely from the expected target average flows and characteristics because of extraneous flows

and/or flow control limitations within the plant. Under such conditions, maintaining average flows higher than target flows is desirable, as it precludes any uncertainty about the plant’s ability to treat the target loadings.

A calibrated model of the plant is a useful and acceptable tool to demonstrate performance for conditions not encountered during field testing, such as peak cold or hot weather conditions. For example, since nitrification criteria are different for summer and winter conditions, the model can be used to predict the performance for the condition not encountered in field testing, thereby saving both time and resources.

The successful demonstration of the plant’s ability to treat target flows and loading, through field testing and calibrated model simulations, led to MOE approval for the desired capacity of 15,400 m3/d for the Simcoe WWTP.

Wastewater Treatment

Wetlands beds with plant growth. sludge build-up in lagoons and FWS beds, winter-time high effluent BOD, costly intermediate pumping, and liner damage by burrowing mammals in the wetlands.

An innovative upgrade project was initiated. It also took into consideration the effluent nutrient loading requirements of the Chesapeake Bay Tributary Strat-

egy. Upgrades were planned in two phases, completed in 2005 and 2008.

Phase I upgrades involved construction and addition of new treatment beds and mainly included: • Raising the elevation of two partially excavated, non-constructed (1996 roughcut only) FWS wetland cells (to eliminate intermediate pumping needs) and re-

designing them to make one large FWS cell; and, • Addition of a new 24-inch-deep re-aeration zone in the central section (approximately one-third of total bed/wetland cell area) and a heavier 40-mm HDPE liner.

• Installation of a new effluent manifold for additional flows from the wetlands beds.

Both Phase I and Phase II designs included deeper re-aeration zones in the free water wetlands beds to ensure that they would remain well oxygenated and that aquatic plants would not choke the beds out after a number of years, as had occurred in the original FWS beds. Also, proper water levels are now maintained in the FWS beds (two feet or less, versus three to four feet in the original beds).

WWTP operational data were monitored between January 2006 and March 2010, and were compared with the system’s National Pollution Discharge Elimination System (NPDES) limits. System performance prior to and after upgrades provided an insight into process improvements.

For analysis purposes, only the stabilized system data were taken into consideration, i.e., prior to upgrades (before August 2006) and after upgrades (March 2009 to March 2010). Although Phase I upgrades were performed prior to August

0.04 MGD, whereas the average effluent BOD increased from 4.3 to 15 mg/l.

However, concentrations remained within effluent NPDES permit limits. The reason for the increase in effluent BOD was probably due to the use of free water cells versus subsurface cells for the final stage (beds). Sometimes algae add to effluent BOD/ TSS in free water surface beds.

Other NPDES parameters, including TSS (total suspended solids), fecal coliform and pH, remained within the permit limits before and after upgrades. Average treatment plant effluent nutrient data for TKN (total Kjehldahl nitrogen), TN (total nitrogen) and TP (total phosphorus) for the stabilized systems before and after upgrades were monitored.

Sampling data along with Discharge Monitoring Report’s data indicate that average effluent TKN, TN and TP concentration decreased from 24.0 mg/l, 24.5 mg/l and 4.0 mg/l respectively before upgrades, to 13.1 mg/l, 15.0 mg/l, and 2.4 mg/l respectively, after upgrades, despite an increase in average daily flows.

Wetlands

Wetlands excel in treating industrial waste streams

By Mark O. Liner

An engineered wetland for treatment of petroleum hydrocarbons.

T

here is considerable interest in the water industry in the potential applications of treatment wetlands, particularly with regard to industrial waste streams that are complex and challenging.

With natural systems, the process usually starts with a need for wastewater treatment in areas where there is limited access to a sewage plant. This could include the treatment of tailing pond water, landfill leachate, contaminated groundwater, or spent deicing fluid at airports.

In each case, there is a unique blend of wastewater, with its own particular requirement for pollutant removal.

A variety of wetland technologies are available, and different types of wetlands can be combined to offer a customized treatment solution.

56 | January 2011

1. Surface flow wetlands. These are essentially man-made equivalents of natural marshes and are an effective option for projects that combine multiple uses such as water management, green space, recreational use, and wildlife habitat. Because they can handle higher sediment loads than other types of wetlands, they are a popular option for stormwater management.

2. Subsurface flow wetlands. In this scenario, beds of gravel or peat are used and the water is not exposed during the treatment process. This makes subsurface flow wetlands suitable for applications where odours may be an issue, or where mosquitoes may be a concern. These wetlands can be utilized for horizontal-flow and vertical-flow applications.

Adding a mulch layer on top of the

wetland bed insulates the system, allowing year-round operation in cold regions such as Canada. In addition, subsurface flow wetlands can be designed with reactive materials, such as limestone, in the bed to stabilize and buffer the pH of water being treated.

A key benefit associated with subsurface flow constructed wetlands is that the system is not attractive for birds because the water is not exposed. This opens up opportunities to build treatment units to handle airport deicing fluid runoff within an airfield perimeter, for example.

3. Mixing and matching wetland types.

This approach allows the advantages of different wetlands being combined to meet complex, multi-stage treatment goals. Certain types of treatment challenges, such as contaminated groundwa-

Jan2011_ES&E_D4_ES&E 11-02-02 2:20 AM Page 57

Wetlands ter or landfill leachates, often involve a combination of different pollutants, e.g., metals combined with petroleum hydrocarbons.

Enhancing engineered wetland performance Engineered wetlands are designed to allow some degree of process control over the system, in order to improve overall treatment efficiency. Forced Bed Aerationâ&#x201E;˘ is one example of a common engineering application used to supply additional oxygen to the microbial community. When treating petroleum hydrocarbons, this â&#x20AC;&#x153;intensifiedâ&#x20AC;? approach can significantly reduce the area required for treatment. Aerobic bacteria inhabit the substrate and thrive in the additional oxygen delivered to the gravel bed by the aeration system.

The aesthetic quality of the system is enhanced by wetland plants that root in the saturated zone below the insulating mulch layer. Water flows beneath the mulch layer, which acts as an insulating blanket and makes engineered wetlands suitable for cold-climate applications.

Other engineering tools also used in the design of sewage plants, such as aer-

ation, reactor configuration and online monitoring, are now being incorporated into natural treatment systems.

Wetland treatment systems are particularly valuable when long-term waste or

pollution problems are the challenge, due to their longevity and simplicity.

They also provide a stable treatment process to meet regulatory compliance continued overleaf...

needs in cases where the source of the contamination is remote. Just as natural systems are effective in the treatment of solids, nutrients and organics, they can also provide treatment for complex ele-

ments, such as selenium, phosphorus, trichloroethylene, methyl tertiary butyl ether, tetrahydrofuran, aniline and nitrobenzene.

Historically, constructed wetlands have

been used for municipal wastewater sources, whose characteristics vary little from project to project. In industrial treatment applications, where compounds requiring treatment can be a complex mix, bench-scale testing, modeling and process sizing are critical steps in the system design process.

Unlike domestic applications, industrial wastewaters may have little or no prior treatment history. Pilot testing provides quick and simple proof of concept and empirical guidance for full-scale design.

Wetland pilots can be quickly conducted on-site at the facility to demonstrate real results in real time.

Examples of wetland industrial waste treatment Treatment wetlands are an effective choice in a host of industrial wastewater applications, and several key industries are adopting them as the treatment of choice for highly complex waste streams.

Here are two prime examples of environmentally effective industrial treatment using wetlands: 1. Airport deicing. The environmental effects of deicing fluids are mostly related

Environmental Science & Engineering Magazine

Jan2011_ES&E_D4_ES&E 11-02-02 2:20 AM Page 59

Wetlands to the high oxygen demand they exert when released to rivers and streams. With large airfields producing significant runoff, stormwater storage volumes are typically sized in the millions of gallons.

Engineered wetland systems provide a simple and robust treatment process that can be ramped up or down to meet varying treatment demands, with minimal staff time. They have been adopted by airports in the United States, Canada and the United Kingdom.

To reduce sewerage costs and meet stormwater discharge limits, the Buffalo Niagara International Airport required an on-site treatment option for deicing liquid. To be effective, the system needed to fit within the airport; treat cold and dilute deicing liquid; have a low profile; not be a bird strike hazard; have low sludge and odour production; be capable of handling seasonal variations; and be integrated into the existing stormwater management system.

An engineered wetlands system was incorporated as an essential component in the redesign of the airport’s stormwater management system. It provides treat-

ment of “first flush” stormwater, which is heavily laden with glycols during the deicing season. To treat glycol, the wetland includes Forced Bed Aeration technology, which supplies oxygen uniformly over the system and permits operator control of treatment. Distribution of wetland influent is also optimized to reduce “bio-clots” within wetland media.

Also important to the project was a treatability study that established coldweather reaction rates for the treatment of spent deicing liquid.

2. Petroleum hydrocarbon-contaminated water. Petroleum producers are regularly faced with the challenge of remediating contaminated sites, in order to return them to viable use. Engineered wetlands have emerged as a leading technology for on-site bioremediation of petroleum hydrocarbon-contaminated water.

An oil refinery once operated on land currently home to the State University of New York’s Wellsville campus. As a result of the historical refinery practices, the groundwater was contaminated with hydrocarbons. A wetland system was de-

signed as a long-term solution to treat 280,000 gallons per day of contaminated groundwater from the former refinery.

The design incorporates an upgrade of the adjacent railroad tracks to trails and paths, restoration of the adjacent river swale, and a 20-acre site restoration plan that utilizes native plants (trees, shrubs, wildflowers, grasses and wetland plants).

Other applications include treating acid mine drainage and removal of heavy metals in the mining industry, treatment of landfill leachate and agricultural waste from farming and food production operations.

It is clear that there are a variety of industrial wastewater challenges requiring efficient and cost-effective treatment to protect the environment. Evolving treatment approaches and sufficient testing of new system designs are critical to dealing with the increasingly complex pollutants of the present and the future.

AWWA issues statement on fluoride The US Department of Health and Human Services has proposed that the recommended level of fluoride in drinking water be set at the lowest end of the

60 | January 2011

current optimal range to prevent tooth decay. Simultaneously, the US Environmental Protection Agency is initiating a review of the maximum amount of fluoride allowed in drinking water.

In response, American Water Works Association’s Executive Director, David LaFrance said that AWWA believes that the best science should drive decisions related to fluoride and other water quality issues. He added that the announcement from HHS and USEPA affirms that community water fluoridation at optimal levels is beneficial for preventing tooth decay. The proposed recommendations properly take into account new scientific data and recognize that people today have access to more sources of fluoride.

“The goal of community water fluoridation is to achieve the desired oral health benefit while minimizing potential health risks. That is why water providers undergo thorough and extensive training to safely apply fluoride in the amount recommended”, he said, adding that “AWWA would carefully study the new recommendations and actively assist the

water community in interpreting and responding to them.” www.awwa.org

Greenpeace releases review of forest-products customers Greenpeace has released its 2010 Boreal Marketplace Review of the performance of 23 major forest-products customers on their commitments and actions to protect the boreal forest and the endangered woodland caribou.

According to the review, well-known companies that purchase forest products, such as Kimberly-Clark, RONA and Office Depot, have responded to the ecological crisis in the boreal forest and are following up on their commitments to make changes. The review also highlights less responsible companies.

Corporate customers can make an im-

United States EPA criticized A new effort by the US Environmental Protection Agency to stem mounting water pollution from pharmaceuticals will be ineffective and may make matters worse, according to comments filed by the Public Employees for Environmental Responsibility (PEER). EPA is attempting to stem the disposal of drugs by health facilities into sewers.

According to PEER, the drinking water of approximately 50 million Americans is currently contaminated with chemicals from pharmaceuticals. The largest pathway for this type of pollution is the general population. Many components of drugs and supplements are not completely metabolized by the human body and are then excreted. Another pathway is the disposal of unused medicines and drugs, which are often flushed down the toilet or washed down drains.

Last summer, EPA issued a draft “Guidance Document: Best Management Practices for Unused Pharmaceuticals at Health Care Facilities” in which it states “the Agency believes that these facilities

dispose large quantities of unused pharmaceuticals to sewers.” PEER argues that this voluntary guidance will likely not change medical facilities’ practices and instead urges EPA to ban sewage disposal of pharmaceuticals.

In this region of the world, water scarcity is a harsh reality.

The privately-operated Rabigh Sewage Treatment Plant will meet Title 22 requirements for unrestricted irrigation. Parkson's design will recycle much of the wastewater effluent. A least 70% of the flow will be used for landscaping irrigation throughout the residential community. The plant needs to remove 96-99% of incoming BOD, and be able to operate in an environment which can reach 50° C. www.parkson.com

Soil recycling project at pilot stage Last September, the Netherlands Soil Partnership (NSP) and Stuyvesant Environmental Contracting Inc., with support from the Consulate-General of the Netherlands, hosted a workshop in Toronto to discuss brownfield remediation technologies, such as soil washing and other innovations in the treatment of contaminated soils and sediments. Stuyvesant and its partner Tetra Tech offered attendees a tour of their soil washing facility, which is part of Waterfront Toronto’s Pilot Soil Recycling project.

Waterfront Toronto established the Port Lands Pilot Soil Recycling facility in July 2010 as part of its soil management strategy and overall commitment to sustainability. The objective of the pilot is to determine the viability of treating and reusing impacted soil as an alternative to the traditional digand-dump disposal of brownfield soil.

Waterfront Toronto anticipates that it will need to manage approximately 2,000,000 cubic metres of contaminated soil over the next 10 to 20 years. By recycling, it would be treating soil near its source, diverting it from landfill, and providing a source of treated soil that could be used in waterfront revitalization projects.

WaterRF to evaluate new coating technologies The Water Research Foundation (WaterRF) will be conducting research that will comprehensively evaluate lead service line (LSL) lining and coating technologies as alternatives to full or partial LSL replacement. Research also will evaluate the use of these coatings as a means of protecting and repairing both lead and copper service lines.

This research will provide the science based information and supporting documentation needed to make informed decisions regarding lining and coating of both lead and copper service lines.

It should prove invaluable to all parties involved in the evaluation of existing service lines to determine how that drinking water infrastructure can be cost-effectively maintained or repaired. www.waterRF.org

He also noted that a transparent monitoring system with easily accessible and credible data is essential as Alberta continues to transition to a cumulative effects system of environmental management.

The experts will also provide detailed action plans on how the environmental system can be expanded to all media in the oil sands region - air, land, water and bio-diversity - and also how the system can extend throughout the entire province.

Environment Minister Murray Coell has invited British Columbians to comment on a proposed new Water Sustainability Act. This would replace the existing, century-old Water Act and ensure that the use and management of water is sustainable for current and future generations.

The Living Water Smart blog will be the focus of this phase of engagement on the proposed act. British Columbians are encouraged to get involved on the blog, where there will be a number of successive posts about the proposed new act.

Participants can submit comments on the blog, as well as pose and rank questions that are most important to them and their communities. www.livingwatersmart.ca

The Corporation of the Municipality of Lambton Shores pleaded guilty to one violation under the Ontario Water Resources Act and, on September 28, 2010, Landmark Tank & Tower Services Corp. pleaded guilty to the same charge of discharging contaminated water into the Hobbs McKenzie Drain.

The Court heard that the town hired the company to clean and inspect a drinking water standpipe in the Village of Arkona. When the standpipe was opened by the company, it was found to contain 2,000 gallons of a red mixture of iron rich water and solids. The company pumped the material out of the standpipe and into the spillway that flowed into the municipal

pact on total balance is not significant.

The percentage of removal of total nitrogen during the warm period and with both reactors in operation averaged 70%.

When shifting to one reactor configuration, the percentage of removal dropped to 60%. Average BOD loading for March and April 2007 was around 200 kg BOD/d, and, based on the synthesis of new biomass and nitrogen assimilation, could not be responsible for more than 25% of removal. Therefore, the excess nitrogen removal can only be attributed to the denitrification process.

Conclusion Process performance testing started in July 2006 and continued till April 2007.

CFID SBR system performances were excellent and consistently in compliance with the design criteria for effluent qual-

ity. Analyses of BOD5, TSS, ammonia and phosphorus concentrations in the effluent were always very low and almost never exceeded discharge limits.

Full nitrification was observed. Even at low temperatures, total ammonia in the effluent remained well below the targeted concentration. Inherently, the CFID SBR system provided partial denitrification, despite the lack of mechanical mixing.

The CFID SBR, with its added flexibility, allowed the treatment process to provide more than satisfactory results in particularly challenging conditions where only one reactor was in operation with a high inflow/infiltration rate.

Water Treatment

How much are consumers willing to pay for municipal water?

M

any water utilities are challenged to maintain service levels in the face of aging infrastructure, population growth, and increasingly stringent regulations. In many cases, most of the revenue for needed investments will come from customers through increased rates and fees.

Water utilities can gain from integrating customer preferences into investment planning. Utilities have typically gathered information from their customers through their customer service representatives, public meetings, and satisfaction surveys. While information from these sources is important, it is often not representative of all customers, making it difficult to incorporate into utility decision-making.

Economic valuation surveys allow for the estimation of customer willingnessto-pay, or the value customers place on a proposed investment. This quantitative input from customers can be used by the utility to improve investment prioritization and rate setting, and to strengthen customer relationships.

The AWWA Research Foundation has released a report entitled â&#x20AC;&#x153;Assessing Customer Preferences and Willingness to Pay: A Handbook for Water Utilitiesâ&#x20AC;?.

Research for the report first consisted of a literature review on stated-preference survey methods, focusing on how they had been previously applied by water utilities. Best practices were examined for administering surveys and identifying issues involved in surveying different demographic groups, such as non-English-speakers.

Interviews and site visits among the five partner utilities, including the City of Ottawa, were conducted in order to assess information about customer preferences they would ideally like to know; potential investments where customer input would be most beneficial; and how they would use data on customer willingness-to-pay.

Next, two stated-preference methodologies were tested, choice experiments (CE) and the contingent valuation method (CVM), in customer surveys conducted in partnership with the Albu106 | January 2011

querque Bernalillo County Water Utility Authority (ABCWUA). The surveys addressed three proposed investments: water-pipe renewal, water reuse, and renewable energy. Survey development included literature reviews, interviews with utilities, focus groups, debriefings, and a pretest.

Results and conclusions The results illustrated output from an economic valuation, using data from surveys administered to customers of the ABCWUA. The most expansive survey, the Full CE, examined six attributes: additional monthly cost on the water utility bill, average length of outages, frequency of outages, rate of advance notification, share of green space irrigated with reuse water, and share of utility energy from renewable sources.

Higher costs, longer average outages, and more frequent outages made the average customer worse off, while greater rates of advance notification, greater use of reuse water, and greater reliance on renewable energy, all made the average customer better off.

Results were consistent across all models. In the linear main-effects model, customers were willing to pay an additional $0.78 per month to avoid experiencing an additional outage over the next five years, and $0.75 per month to avoid the average utility outage length increasing by one hour.

They were willing to pay an additional $0.06 for each one-percent increase in the share of time customers received advance notification of an outage, $0.17 for each one-percent increase in the share of green space irrigated with reuse water, and $0.13 for each one-percent increase in the share of renewable energy used by the utility.

The project also estimated willingness-to-pay to avoid a substantial reduction in service levels due to water-pipe failures. The specific scenario valued was avoiding five outages over five years, a 20% rate of advance notification, and an average outage length of eight hours. Across all survey types, individuals were willing to pay a significant amount to avoid this scenario. For example, on average, individuals who received the water-pipe survey instrument were willing to pay an additional $8.68 per month on their bill to avoid this scenario. For comparison, estimated willingness-to pay was $10.70 per month using the full CE survey instrument.

Applications and recommendations This research report is written as a user-friendly handbook for water utilities on how to conduct their own economic valuation surveys. Basic tools are provided to design, implement, and analyze economic valuation surveys using the customer survey administered for the ABCWUA. Examples are provided on how the results of economic valuation surveys can be applied in utility decision-making.

Integrating customer preferences into utility investment planning provides many advantages. Economic valuation survey data can assist the utility in defining appropriate service levels. Costs and benefits experienced by customers of a proposed utility project can be quantified, and the utility can use this to assess the cost-effectiveness of the project. Investment selection and prioritization, and rate setting, can be improved. Overall, the utility will be able to provide sustainable levels of service to customers over time.
