ES&E Readers Remember

Thomas Peter Davey June 8, 1930 - November 25, 2014

operated in Canada. It made a difference. Tom expressed the best possible ideals while remaining pragmatic, and never accepting of the status quo. Peter Van Caulart, Environmental Training Institute

om was an ardent supporter of the engineering profession, an excellent journalist and a singular resource on the history of our industry. I will miss his wit and humour and I will particularly miss our discussions of WW2 history, which I enjoyed immensely. His memory will live on in all of us who knew and admired him. Greg Jackson, ACG Technology

om was easily one of my favourite people, a bright light in his writing and in his endless supply of innovative and creative ideas. He was also a humble man, whenever we talked about science and chemistry he would claim to be unable to understand, but he’d also add his own take and invariably come up with his own version of the topic, and his was the more sensible and workable plan. I loved our talks over a lunch or drink and I knew I was lucky to have him as a friend and an ally in the environmental battles of the 70s, 80s, and 90s. I’ll miss him. We’ll all miss him. Jim Bishop

t was with great sadness that I announced the passing of Tom Davey, Founding Editor of Environmental Science & Engineering Magazine in our last issue. Editorial comments and socializing at industry events were Tom’s forte, so it is very comforting to his family and ES&E staff to have received so many condolence messages, recollecting these memories. We wanted to share some of these heartfelt messages. Steve Davey, Editor.

om was an exceptional person, tireless advocate of the engineering profession, my mentor for many years, inspiring, charismatic, visionary, innovative, and witty even when embracing new challenges. He was passionate about the world’s wellness and was sharp, quick on his feet and lots of fun to be with. My memories of Tom are endless and wonderful. Tom’s legacy will live forever. I feel very fortunate, enriched and proud to have known him Dusanka Filipovic, Blue Zone Technologies

om was a trail blazer, advancing the environmental sciences into the political and social agendas of corporations and government alike. By his skillful oratory and penmanship he expressed his conviction that the environment had rights worth protecting. He was the environment’s ultimate champion. It’s said that “one’s judgement is only determined after one’s influence has past.” With that statement ringing in my head, I can tell you Tom influenced me and I’ve influenced over 30,000 treatment operators so far in my career and so I expect his influence to be perpetuated forward exponentially. I’m only one, but my wife Carol can say the same when she worked for TRICIL, (an early Ontario waste management company). ES&E was factored into how that firm s executive

ike so many in our industry I was blessed with the opportunity to meet and chat with Tom on many occasions. His insight into our industry, wit, and unique turn of a phrase will long be remembered. Larry Madden, C&M Environmental

am so sorry to hear of Tom’s passing. The engineering profession that he supported so strongly and the water industry will miss his wit and his insight. Stephen Nutt, XCG Consultants

om was an accomplished writer and thinker who became a point of reference for the Canadian water and environmental industries. Michael Albanese, H2Flow

always enjoyed conversing with Tom at conferences and industry functions. He was a truly a genuine person. Ahron Nahmias, Metcon Sales and Engineering

remember Tom from when I started in the water industry back in 1987. He could always remember your name and always approached you at conferences. He always made us feel good and that we were embarking on a most noble profession, that of keeping our water clean. I believe that he also used the information from the various “chats” he had in his editorial comments. These discussed the current state of the water industry and combined humour to deliver powerful messages. With Tom, the adage “the pen is mightier than the sword” was something he took to heart. With his pen he helped the water industry become a much more rigorous and accountable industry. The Davey family is the legacy of Tom and you have kept up the great work that your father began. Keep up this great work, challenge the industry and know that your creative works will honour your father’s memory and his actions for the next generation. A truly great man...

JF.15 Editorial_Tom.indd 8

y first encounter with Tom was through his book “For Whom The Polls Tell”. I told my boss I’d like to meet this witty man! Emil Cocira, Can-Am Instruments

henever I spoke to Tom at various events, he was always encouraging younger people and always had a warm story to tell. He will be greatly missed by many. You can be very proud of the legacy of the magazine that you and he built and will continue to prosper. Christine Hill, XCG Consultants

e will always remember Tom as a man of strong character and great ‘gusto’. He was kind and thoughtful and a great supporter of all good things. Tom’s energy was a force to be reckoned with - one that does not necessarily go gently into that good night, but which must surely remain present as a flame to light and warm the hearts and minds of all who knew him. We feel privileged to count ourselves among that number. Lawrence and Judy Earl, CANECT

om was a thoroughly entertaining and erudite character who will be long remembered for his enthusiasm and unflaggin support for those of us working to keep the place clean. Hugh Tracy, Delcan

The charge stemmed from a February 4, 2012 report that approximately 391 cubic metres of process water had been released from a broken pipeline near Marsh Head Creek. This creek is fish-bearing and fl ws into the Athabasca River. An operator failed to abide by company policies related to emergency shutdown equipment, bypassed emergency shutdown devices and failed to return them to service. The operator’s failure to check the pipeline resulted in the leak remaining undetected for nearly two days. The company began an immediate cleanup of the release once it was discovered. Remediation was completed in June 2013. alberta.ca

Findings published from wind turbine study Health Canada recently published findings from the Wind Turbine Noise and Health Study. It found no evidence to support a link between exposure to wind turbine noise and any of the self-reported or measured health endpoints examined. Launched in 2012, in collaboration with Statistics Canada, this study explored the relationship between exposure to wind turbine noise and the health effects reported by, and measured in, people living near wind turbines. The study did demonstrate, however, a

relationship between increasing levels of wind turbine noise and annoyance towards several features. These included turbine noise, vibration, shadow flic er, and the aircraft warning lights at their top. Findings are available on Health Canada’s website and are said to provide a more complete overall assessment of wind turbine’s potential impacts on health and well-being. Health Canada said it is important to note that the findings from this study do not provide definit ve answers on their own and must be considered in the context of a broader evidence base. The study was conducted in Southwestern Ontario and Prince Edward Island. It included 1,238 out of a possible 1,570 households, living at various distances from 399 separate wind turbines in 18 wind turbine developments. It measured health-related indicators, including hair cortisol as a biomarker of stress, blood pressure, resting heart rate and sleep. news.gc.ca

WaterTAP tour highlights success in Ontario Prior to the second annual World Water-Tech North America Summit in Toronto in November, the Water Technology Acceleration Program (WaterTAP) held a media tour of Ontario water companies in the Greater Toronto Area. Beginning in downtown Toronto, Shaun McKaigue, CEO of FER-PAL

Infrastructure gave a tour of his company’s project at the University of Toronto’s St. George campus. This will see the relining of dirty and damaged water pipe using cured-in-place piping. The tour then traveled to furniture manufacturer Calstone Inc., where owner and president, Jim Ecclestone showed off inventive green additions to the company’s 55,000 square foot manufacturing facility. These included air cleaning plants, rainwater harvesting and heat extraction from machinery. Notably, Calstone is finishing a rainwater diversion system which will irrigate a small pond and naturescape feature alongside the building. It will also be used to store rainwater during storm events, releasing water on dry days to reduce the load on sewerage systems. Newterra, UV Pure and data-mining and analytics company Watrhub, gave presentations on their respective company histories, products and developments. A common feature between water treatment company Newterra and UV Pure was the benefits of modular equipment and systems. This ability is increasingly being called upon to deliver decentralized solutions to water and wastewater treatment applications. At the last stop of the tour in Whitby, Jodi Glover, CEO of Real Tech Inc., took the group through the expanding firm s new location. It has launched new products and increased the size of its continued overleaf...

According to Mergelas, WaterTAP is working with Ontario water companies to build better businesses and company capacity, and to engage with the end users. www.watertapontario.com

WERF launches new co-digestion project The Water Environment Research Foundation (WERF) has initiated a second project on furthering co-digestion. “Co-Digestion of Organic Waste: Addressing Operational Side Effects” will help increase the number of utilities performing co-digestion by providing tools that enable them to better understand its implications, and reduce roadblocks and uncertainty associated with the process. A primary benefit of co-digestion is that it uses existing infrastructure and expertise to divert food waste, fats, oils and greases from other methods of disposal. This study will consist of two major phases. The first phase will focus on analysis of available operations and maintenance data and identification of

operations and maintenance issues. The second phase will focus on sampling at selected participating treatment facilities and bench-scale testing to identify variability in supplemental organic waste characteristics. This project will provide specific benefits to municipal wastewater treatment facilities, food-processing industries, and the dairy industry. www.werf.org

Ontario re-introduces Invasive Species Act The Ontario government has re-introduced the proposed Invasive Species Act. Ontario’s forests, particularly those in the south, have been challenged by invasive species, among them the Emerald Ash Borer, Dog-Strangling Vine, Asian Longhorn Beetle, and Buckthorn, to name a few. These species have wreaked havoc. These challenges to the natural environment will, if unaddressed, continue to negatively impact forests and habitats. The Invasive Species Act, if passed, will seek to integrate early detection methods with rapid response solutions designed to combat invasive species.

The automakers will pay a $100 million civil penalty, the largest in Clean Air Act history, to resolve violations concerning the testing and certification of vehicles sold in the U.S. Kia and Hyundai will also spend approximately $50 million on measures to prevent any future violations and will forfeit 4.75 million greenhouse gas emission credits. These are estimated to be worth over $200 million.

The nuclear energy industry has long predicted a renaissance in popularity, yet growth in nuclear electricity production has been stalled for years. Renewable energy, by contrast, continues to expand rapidly. Fossil fuels, however, continue to dominate global production, accounting for roughly two-thirds of world electricity production. Nuclear’s share of global power production has declined steadily from a peak of 17.6% in 1996 to 10.8% in 2013. Following the Fukushima Daiichi disaster in March 2011, Japan shut down all but two of the country’s reactors. Germany has pledged to do away with nuclear by 2022, cutting down

nuclear’s share of energy production to 18%, from nearly 25% in 2011. Renewables increased their share from 18.7% in 2000 to 22.7% in 2012. Hydropower was the leading source of renewable electricity, while wind contributed 3.4% and solar, 0.6%. But wind and solar energy are the fastest growing worldwide. Between 2000 and 2012, wind power grew nearly 16-fold and solar jumped 49-fold. From its beginnings in the mid1950s, global nuclear power generating capacity rose rapidly and reached 298 gigawatts (GW) in 1987, an average annual growth of 9.3%. In the following 23 years, however, only 77 GW of capacity were added to reach 375.3 GW, at a rate of 3.4% per year. From this 2010 peak, capacity declined to 371.8 GW in 2013, according to the International Atomic Energy Agency. Adverse economics, concern about reactor safety and proliferation, and the unresolved question of what to do with nuclear waste have put the brakes on the industry. www.vitalsigns.worldwatch.org

Canada introduces regulations to prevent mercury releases Products Containing Mercury Regulations are the first of their kind in Canada and prohibit the manufacture and importation of most mercury-containing products. The federal government is aiming to prevent releases of mercury to the environment and the food chain. Canada has a particular interest in see-

ing reductions in mercury as many Canadians enjoy wild game as part of their diet. In Canada’s north, food from wildlife is a dietary mainstay for people in the Arctic. These regulations will introduce new limits on the amount of mercury allowed in different types of products to be manufactured and imported. New labelling requirements will also be introduced to inform consumers about the presence of mercury, as well as safe handling procedures and options available for their endof-life management. Action is already being taken on producing guidance documents for the disposal and end-of-life for mercury containing lamps. In the last 40 years, Canada has reduced mercury emissions by more than 90%. However, 95% of atmospheric mercury deposition in Canada comes from foreign sources. According to Environment Canada, the Products Containing Mercury Regulations will eliminate about two tonnes of mercury used, on average, each year from 2015 to 2032.

New contaminants found in oil and gas wastewater Duke University scientists have discovered high levels of two potentially hazardous contaminants, ammonium and iodide, in wastewater being discharged or spilled into streams and rivers from oil and gas operations in Pennsylvania and West Virginia. “This discovery raises new concerns about the environmental and human health impacts of oil and gas wastewater in areas where it is discharged or leaked directly into the environment,” said Avner Vengosh, professor of geochemistry and water quality at Duke’s Nicholas School of the Environment. “Our data clearly show that the current brine treatment practice in Pennsylvania is not sufficien to remove these contaminants.” When dissolved in water, ammonium can convert into ammonia, which is highly toxic to aquatic life. The scientists detected ammonium levels of up to 100 mg/l in oil and gas effluents they collected at the wastewater discharge sites. Those levels are more than 50

times higher than the EPA water-quality threshold for protecting freshwater organisms. Elevated iodide in surface water can promote the formation of highly toxic byproducts in drinking water when the iodide mixes with the chlorine used to disinfect the water at municipal treatment plants located downstream from oil and gas operations. Such disinfection byproducts are not monitored by state or federal agencies. Public concern for water contamination has focused on the impact of hydraulic fracturing fluids from shale gas exploration, but the new study shows that wastewater from conventional oil and gas exploration contains levels of ammonium and iodide that are just as high. “By measuring naturally occurring ammonium and iodide in numerous samples from different geological formations in the Appalachian Basin, including fl wback waters from shale gas wells in the Marcellus and Fayetteville shale formations, we show that fracking fluids are not much different from conventional oil and gas wastes,” said Jennifer S. Harkness, lead author of the study and a PhD student at the Nicholas School of the Environment. Previous studies have shown that fracking fluids contain high levels of salts, barium and radioactive elements, in addition to man-made chemicals added in the process. To conduct the new study, researchers collected and analyzed 44 samples of waters produced from conventional oil and gas wells in New York and Pennsylvania and 31 samples of fl wback waters from hydraulically fractured shale gas wells in Pennsylvania and Arkansas. They also collected and analyzed oil and gas effluents that were being directly discharged into streams, rivers and surface waters at three disposal sites in Pennsylvania and a spill site in West Virginia. “Wastewater from both conventional and unconventional oil and gas operations is exempted from the Clean Water Act, which allows their disposal to the environment. This practice is damaging the environment and increases the health risks of people living in these areas, and thus should be stopped,” Vengosh said.

Where did all the oil go? Tracing oil from Deepwater Horizon

By Julie Cohen

ue to the environmental disaster’s unprecedented scope, assessing the damage caused by the 2010 Deepwater Horizon spill in the Gulf of Mexico has been a challenge. One unsolved puzzle is the location of two million barrels of submerged oil thought to be trapped in the deep ocean. University of California (UC) Santa Barbara’s David Valentine, a professor of earth science and biology, and colleagues from the Woods Hole Oceanographic Institute and UC Irvine, have been able to describe the path the oil followed to create a footprint on the deep ocean floo . For this study, they used data from the Natural Resource Damage Assessment process conducted by the National Oceanic and Atmospheric Administration. The U.S. government estimates the Macondo well’s total discharge was fi e million barrels. By analyzing data from more than 3,000 samples collected at 534 locations over 12 expeditions, they identified a 1,250-square-mile patch of the deep sea floo , upon which 2% to 16% of the discharged oil was deposited. The fallout of oil to the sea floor created thin deposits, mostly to the southwest of the Macondo well. Oil was most concentrated within the top half-inch of the sea floor and was patchy even at the scale of a few feet. The investigation focused primarily on hopane, a nonreactive hydrocarbon that served as a proxy for discharged oil. Researchers analyzed the spatial distribution of hopane in the northern Gulf of Mexico and found it was most concentrated in a thin layer at the sea floor within 25 miles of the ruptured well. This clearly implicates Deepwater Horizon as the source. “Based on the evidence, our fin ings suggest that these deposits come from Macondo oil that was first suspended in the deep ocean and then settled to the sea floor without ever reaching the ocean surface,” said Valentine.

“The pattern is like a shadow of the tiny oil droplets that were initially trapped at ocean depths around 3,500 feet and pushed around by the deep currents. Some combination of chemistry, biology and physics ultimately caused those droplets to rain down another 1,000 feet to rest on the sea floo .” Valentine and his colleagues were able to identify hotspots of oil fallout in close proximity to damaged deep-sea corals. According to the researchers, this data supports the previously disputed finding that these corals were damaged by the Deepwater Horizon spill. “The evidence is becoming clear that oily particles were raining down around these deep sea corals, which provides a compelling explanation for the injury they suffered,” said Valentine. “The pattern of contamination we observe is fully consistent with the Deepwater Horizon event but not with natural seeps, the suggested alternative.” While the study examined a specified area, the scientists argue that the observed oil represents a minimum value.

They purport that oil deposition likely occurred outside the study area, but so far has largely evaded detection because of its patchiness. “This analysis provides us with, for the first time, some closure on the question of where did the oil go and how,” said Don Rice, program director in the National Science Foundation’s Division of Ocean Sciences. “It also alerts us that this knowledge remains largely provisional until we can fully account for the remaining 70%.” “These findings should be useful for assessing the damage caused by the Deepwater Horizon spill, as well as for planning future studies to further define the extent and nature of the contamination,” Valentine concluded. “Our work can also help to assess the fate of reactive hydrocarbons, test models of oil’s behavior in the ocean and to plan for future spills.” Julie Cohen is with UC Santa Barbara Public Affairs and Communications.

Career trends and growth very promising in the water quality sector By Jennifer Schultz

areers in water quality are not just in high demand, they are also undergoing rapid changes. Climate change, population growth and urbanization create new challenges that professionals must address to reduce negative impacts on water resources. To determine the current status and future growth of Canada’s water quality workforce, Environmental Careers Organization (ECO) Canada conducted a recent study, titled Careers in Water Quality. Current demand In 2013, Canada had an estimated 1.8 million workers who used environmental skills as part of their work activities. Some 500,000 apply water quality skills in their work, while roughly 83,500 professionals work in core water quality careers. While most industries have a demand for water quality practitioners, the three most likely to hire water quality practitioners are government, consulting firms and ater utilities. Educational requirements, skills and competencies The water quality job market is shifting to higher educational requirements. Nearly 75% of new job openings in water quality require a bachelor’s degree. However, only 25% of the water quality labour force has one. Across most water quality occupations, water quality practitioners require similar environmental skills and competencies such as: • Analyzing or interpreting environmental samples and data. • Liaising and partnering with stakeholders. • Presenting expert information on environmental matters. • Developing sustainable development indicators, plans or strategies, and implementing or monitoring sustainable development strategies or programs. • Conducting environmental assessments. • Developing or implementing environmental communications and awareness programs.

For water quality technicians, employers are looking for workers who can combine hands-on, field sampling skills gained from a technical school or direct work experience, with the analytical skills typically gained through a bachelor’s degree program.

Career options and salaries Research shows that most water quality jobs involve eight broad practice areas: • Integrated water resources and watershed management. • Protection of groundwater from contamination. • Protection of surface water. • Marine water quality. • Aquaculture and food processing. • Municipal water systems, including water treatment, water distribution, wastewater treatment and wastewater collection. • Green building. • Water quality education, communication, policy and planning. Career pathways Water resources engineers, water quality scientists, and professionals in water quality communications, education, policy and planning often begin with a bachelor’s degree. For water quality technicians, it is at least a three-year diploma. Typically, the listed professionals make lateral career moves between dif-

ferent types of roles and employers, such as NGOs, governments, private industry, or consulting. Engineers, water systems operators, and green building professionals, follow more vertical career pathways. These workers progress from entry-level to senior level positions and through progressive management roles. Municipal water systems operators follow a more narrowly defined career path through four classes of certification Based on their certification level and experience, these practitioners move up into system supervisor, operations manager, or facility manager positions. Salaries Earnings for water quality workers vary significantl , both for entry level positions and for workers with experience. These wage variations are linked to different types of employers and practice areas. Employers in mining, oil and gas, and environmental consulting offer the highest paying positions. Annual earnings are lower for workers employed by

governments, conservation organizations, watershed management organizations and other NGOs. The average starting salary for water quality jobs is $55,284. The average salary for workers with at least fi e years of experience is $84,239. Hydrogeologists earn the highest starting salary, at an average of $74,100. Future demand and hiring forecasts The demand for water quality professionals is increasing. Employers of chemists, hydrogeologists, green building professionals, water utility engineers and environmental engineers are the most likely to expect their staffing l vels to increase in the future. While there’s a higher concentration of workers near both of Canada’s coasts and in Alberta, there are different drivers of demand for water quality practitioners in each province. For example, Alberta’s oil and gas industry has driven high demand for water engineering occupations, water quality managers in natural resources, and water quality scientists and technicians. According to water quality professionals, climate change is the most commonly cited trend affecting the water quality job market and skills requirements. Additional factors that will shape the demand for water quality professionals are: • Increasing investment and development in resource industries, such as new mines, oil and gas development, and forestry. • Water quality professionals retiring over the next decade. • Changes in water quality standards including new regulations and technologies.

Corrosion Prevention

Infrastructure corrosion prevention needs a long-term solution By Stuart Reece

itting on a desk in our office is a large piece of wood, a relic of an old water delivery system comprised entirely of hollowed-out logs. It is truly amazing to think of a city that enjoyed water distribution through felled trees. Since that time there has, of course, been a great evolution in the materials used and the attitude towards the importance of protecting our infrastructure. Too often though, there have been short-term solutions adopted in dealing with the long-term problem of corrosion. I once heard someone say that, because they use plastics in their municipality, they need not worry about corrosion. “Are there no metal parts? ” I inquired. He said yes, but, as there are so few, they wouldn’t be much of a target. It is true that much of what goes into the ground these days as part of a city’s water delivery system is plastic. Durable, safe and long-lasting, the concerns of corrosion are no longer present with these lines. It is now only the metal connections, restraining rods and other pieces that are of concern. The reality is, however, that with the increased use of plastics, the agents of corrosion are more focused on buried metals. The target has effectively become bigger not smaller. Another and perhaps more common assumption is that factory epoxy coatings will offer sufficient defence. Something to consider though, is that such coatings are easily damaged in the long journey from factory, to wholesaler, to contractor, to final installation. A simple nick here and a scratch there, expose the metal to air, water and soil, allowing corrosion to start. Another dangerous assumption is that stainless steel bolts offer adequate corrosion protection. As all metals corrode, we now have different metals in contact with one another, with each corroding at a different rate. More importantly, the grouping of dissimilar metals, namely stainless steel with others, has been proven to hasten the corrosion

While sac-nuts and anodes do the job that they are tasked with, it is a short-term solution to a long-term problem. Depending on the corrosivity of the soil and the presence and intensity of stray current, the lifes-

pan of sacrificial systems can vary considerably. This approach to corrosion prevention requires revisiting, redigging and replacing spent anodes. This, of course, can be costly. The three-part petrolatum system, developed by Denso in the 1920s, provides a permanent solution. Denso Paste arrests existing corrosion and aids in adhesion. Denso Profiling Mastic is used to fill voids and cover sharp edges, and, finall , Denso Tape is used to wrap an entire fitting. By completely preventing contact with air, water and soil, the Denso system protects the metallic components of infrastructure from corrosion, while still allowing simple removal and easy access for service or inspection. This protection is not a new development. In fact, there is evidence of the effectiveness of the petrolatum system on applications as old as 80 years. In this example, a portion of Denso tape was removed from a section of steel pipe installed in the 1930s. The pipe was still in pristine condition with even the mill stamp still visible. Tape was re-applied

and the pipe reburied. With the overall cost of the Denso system being a fraction of the cost of repair and replacement, it is not only effective but efficient and affordable. A more recent example of the benefits of the petrolatum system exists in the Greater Toronto Area. A little over a decade ago, a municipality adopted the Denso system and they have seen the number of breaks due to corrosion steadily decrease. As a result of their preventa-

tive measures and because they now no longer have to contend with such breaks, they have increased capital for expansion, improvement and development. The Denso petrolatum system is installed on-site, requires minimal training and can protect against damage to factory applied coatings. It protects all metals, even dissimilar metal groupings from corrosion and eliminates the need for cathodic protection. Regardless of soil conditions or even being constantly

submerged in water, Denso tape will not harden, crack or dry out. Technological developments are ongoing and we must be diligent in assessing their quality and effica y. Sometimes, however, low-tech systems that have existed for a long time may actually provide the best solutions. Stuart Reece is with Denso North America Inc. Email: stuart@densona-ca.com

Alberta municipality evaluating new sewage recycling system By Van A. Ridout, Ali Roshanfekr and Jean Navert

astewater treatment normally includes a combination of physical, chemical, and biological processes to remove contaminants. A new dimension to this is sewage mining. The Sewage Recycling System (SRS), recently introduced into Canada by BioForm Sewage Mining, mines and extracts valuable resources from municipal sewage, recycling them into a high-quality, pasteurized cellulose-based product called RecylloseTM. It is a 100% renewable resource that can be used as an additive in a broad range of industries, helping to offset the rapid depletion of natural cellulose resources. The technology also reduces biosolids treatment and disposal costs. Conventional wastewater treatment Discovered over 100 years ago, the activated sludge process is virtually the

Wastewater Treatment same in most municipal wastewater treatment facilities. This process involves a pre-treatment stage followed by biological degradation and oxidation to remove most of the dissolved organic compounds. The remaining suspended particles are settled and separated, and the effluent is further treated before discharge. Most wastewater treatment plants (WWTPs) face a myriad of challenges, including maintenance costs and a host of environmental issues. With the steady increase in the amount of sewage, wastewater utilities are faced with the challenge of finding more efficien methods of treatment to curtail soaring operating costs, and to defer or avoid having to invest in expanding their existing plants or construct new ones. Consisting primarily of suspended biosolids, sludge is the end product of the wastewater treatment process, and removing it is costly. Typically, treating and disposing of sludge can cost as much as 60% of the total operating expenses of wastewater treatment, rendering it the most expensive part of the process.

Redefining wastewater treatment Founded in 2007, Applied CleanTech (ACT) identified sewage as a valuable resource from which useful commodities could be extracted. The firm then developed an advanced sewage recycling technology that would allow wastewater treatment plants to bypass the production of sludge before the recycling process starts. The Sewage Recycling System is a compact, modular, “plug-and-play” recycling processor. It automatically and continuously extracts suspended biosolids contained in the wastewater stream before they become sludge. It then transforms them into Recyllose. This is accomplished without restricting the fl w to the WWTP, which has 50% fewer solids to deal with. In essence, the SRS transforms sewage treatment into sewage mining. It is being used in the Netherlands, Israel, Mexico and Scotland. It will undergo a full-scale demonstration program in an Alberta municipality this year, before being commercially introduced by BioForm Sewage Mining into the Canadian

market. During this demonstration, an independent, third-party organization will conduct the verification of the technology through the Environmental Technology Verification (ETV) Program, which was created by Environment Canada (and Industry Canada) to verify performance claims. This process will be administered by GLOBE Performance Solutions of British Columbia, the delivery agent for ETV-Canada, with the technology testing being done by the Edmonton Waste Management Centre of Excellence from Alberta. How the SRS works After the coarse screening and grit removal pre-treatment stage, raw sewage is pumped into the SRS, and passes through a primary cleaner to remove excess grit. The SRS employs a multi-stage trapping process to mine cellulose and other useful materials from the fl w and separate them from unwanted materials. Inside the SRS, sewage passes through a trapper to remove suspended solids, continued overleaf...

A reduction in greenhouse gas emissions generated during the operation of a typical WWTP at several stages in the biological process. A reduction in methane (CH4) emissions when a WWTP is operated in an anaerobic mode. A reduction in CH4 emissions resulting from the decay of sludge in landfill. A reduction in carbon dioxide (CO2) emissions corresponding to the reduction of electricity consumed during the operation of the WWTP. A reduction of CO2 emissions corresponding to the reduced consumption of fossil fuels and their replacement using Recyllose pellets.

Sustainable economic benefit From an economic perspective, the SRS offers substantial benefits. In four case studies conducted with municipalities in Israel, the SRS showed the following performance: • Up to a 50% reduction in sludge formation. • Up to a 50% reduction of total suspended solids for the existing downstream WWTP to treat. • Up to a 20% reduction in the biochemical oxygen demand. • Up to a 30% reduction in the chemical oxygen demand. • Up to a 50% reduction of fats, oils and grease for the existing downstream WWTP to treat. • Up to a 30% reduction in the operating expenses of the WWTP through energy, chemical and maintenance cost reduction and biosolids disposal cost reduction. • An increase in the treatment capacity of the existing WWTP (throughput) by up to 30%.

Conclusion Growing environmental awareness has influenced world governments to set ambitious goals towards connecting 100% of the population to reliable wastewater treatment. It is, therefore, vital for us to find solutions to treat the immense amounts of sludge being produced every day from wastewater, make it less harmful to human health and reduce the process’s energy-intensity.

AWWARF releases report on nitrate and arsenic removal using a fixed-bed bioreactor

ontamination of natural water sources with arsenic and nitrate is a major concern everywhere. There is a need for new technologies capable of removing these contaminants simultaneously. Fixed-bed biologically active carbon (BAC) bioreactor systems have successfully removed the oxy-anionic contaminants nitrate and perchlorate. Based on preliminary batch reactor studies, a research team from the University of Michigan and Carollo Engineers, Inc. hypothesized that a fi ed-bed BAC reactor system could be developed to simultaneously remove arsenic and oxy-anionic contaminants such as nitrate, in the presence of sulfate and iron, naturally occurring in groundwater. Removal mechanisms were elucidated through the use of microbial community analyses and solids characterization techniques. A variety of operating conditions were evaluated and optimized at the bench-scale level. The goal was to demonstrate this technology at pilot-scale and then integrate it at fullscale in drinking water treatment plants. A system consisting of two fi ed-bed BAC bioreactors in series was designed and seeded with BAC obtained from lab- and pilot-scale nitrate and perchlorate removal systems. These systems were originally seeded with a mixed community of microbes indigenous to natural groundwater. Using a simulated groundwater containing nitrate, arsenic, sulfate and iron, and feeding acetic acid as the sole electron donor, this system was operated for over 1,000 days. During operation, the empty bed contact time (EBCT), backwashing strategy, and influent iron and sulfate concentrations were varied. System performance was monitored by measuring concentrations of total arsenic, iron, acetate, chloride, sulfate and nitrate. Additional studies of microbial community composition and activity were performed using molecular biology methods. Solids deposited in the reactors were characterized using X-ray ab-

sorption spectroscopy (XAS) and X-ray diffraction (XRD). Results Simultaneous removal of nitrate and arsenic was achieved in the fi ed-bed BAC bioreactor system. Complete denitrification occurred, removing 50 mg/l (as NO3-) to below the detection limit of 0.2 mg/l. Initially, arsenic was reduced from 300 µg/l to below 20 µg/l. However, performance varied during subsequent experiments and effluent concentrations ranged from 10 µg/l to 50 µg/l. Bacteria present in the reactor system were identified by sequencing their 16S ribosomal RNA genes to be closely related to known nitrate-, sulfate-, and iron-reducing bacteria. Analysis targeting specific functional genes coding for enzymes in sulfate- and arsenate-reduction pathways ([bi]sulfite reductase and arsenate reductase) indicated the presence of sulfate- and arsenate-reducing bacteria throughout the depth of the BAC bioreactors. Additionally, specific functional activities measured through messenger RNA abundance profiles were correlated with terminal electron accepting process (TEAP) zones as in-

dicated by concentration profiles of sulfate and arsenic along the depth of the BAC bioreactors. Iron sulfides, mackinawite and greigite, were found to be the dominant crystal phases in the system, suggesting that arsenic removal through adsorption to these solids was an important removal mechanism. It was further determined that sulfur was the nearest neighboring atom to arsenic, indicating that arsenic sulfide were present in the system, and were partially responsible for arsenic removal. By varying the EBCT between 40 and 27 minutes, it was determined that nitrate and arsenic removals were achievable at these contact times. However, other factors, such as iron and sulfate concentrations may determine the EBCT needed for optimal arsenic removal. Experiments varying iron and sulfate concentrations found complete nitrate removal under all conditions. Arsenic removal varied depending on the amount of iron and location of its addition (1st reactor or 2nd reactor). Influent sulfate concentrations tested included 22 and 50 mg/l, demonstrating the fl xibility of this system for treating source waters with variable sulfate concentrations.

Water Treatment The first BAC bioreactor was backwashed every 48 hours, whereas the second BAC bioreactor was only backwashed every three to four months. Initially, nitrogen gas was used during backwashing. Considering the practical advantages of air-assisted backwashing, including simpler operation, improved safety and lower cost, the impact of air-assisted backwashing on system performance was evaluated. It was determined that overall nitrate and arsenic removals with long-term use of either gas were comparable, although a slight impact on arsenic removal in the first BAC bioreactor was observed. It was determined that the two-column system helped keep arsenic concentrations in the final effluent low, even immediately after an air-assisted backwashing event. This study demonstrated that a fi edbed BAC bioreactor system can simultaneously remove arsenic and nitrate from a simulated groundwater, utilizing an inoculum originating from a mixed community of microbes indigenous to

groundwater. Microbial and chemical analyses indicated that the micro-organisms utilized dissolved oxygen, nitrate, sulfate, and arsenate as the electron acceptors in a sequential manner in the presence of acetic acid as the electron donor. Biologically produced sulfides effectively removed arsenic from the water through the formation of arsenic sulfides, and/or surface precipitation and adsorption on iron sulfides. The optimization of EBCT, iron and sulfate concentrations, and backwashing strategy resulted in a set of operational characteristics that can be used during pilot-scale evaluation of this technology. Applications This system removes arsenic through precipitation of arsenic sulfide and adsorption of arsenic on iron sulfide precipitates. Therefore, the concentrations of iron and sulfate naturally present in the contaminated water source are important parameters. Prior to implementation of this system, pilot studies should be conducted to determine opti-

mal operating conditions for each type of contaminated water. The laboratory system was operated with total influent iron concentrations between 2 mg/l and 10 mg/l and influent sulfate concentrations of 22 mg/l and 50 mg/l. The optimal combination of influent iron and sulfate concentrations will vary depending on the concentration of arsenic and other compounds present in each water sample. Future work will evaluate the requirements for post-treatment needed to remove excess carbon, aerate the finished water and provide disinfection. Additionally, characterization of arsenic containing solid waste generated in the system must be performed to determine the long-term stability under disposal conditions. â&#x20AC;&#x153;Nitrate and Arsenic Removal from Drinking Water with a Fixed-Bed Bioreactorâ&#x20AC;?

Minimizing the security risks of M2M communications By Andrew Ginter

he cybersecurity landscape continues to evolve and yesterday’s defenses are no match for today’s attack methods. Critical infrastructures are very real targets of modern attacks, and water and wastewater treatment plants are no exception. The crucial nature of these facilities demands stringent protection to ensure safe and reliable operation of industrial control systems (ICS). This is particularly true when it comes to machine-to-machine (M2M) communications critical to operations. These communications help to facilitate dayto-day functions, but they can unknowingly open the door for remote administration tool (RAT) attacks. As attack tools and methods evolve, cybersecurity best practices must also evolve to keep water plants and drinking water supplies safe and reliable.

The new normal Targeted persistent attacks (TPAs)

are the new normal when it comes to cyberthreats. These modern, interactive-remote-control attacks routinely de-

System Security feat long-standing IT security practices, including fir walls, encryption, antivirus systems and security update programs. They generally begin by compromising the business network at a water utility. A hacker might research the utility’s employees’ social networks to craft very convincing phishing emails to trick them into downloading malware. Or they might launch a more conventional attack on exposed Web servers. Antivirus systems do not catch this targeted malware. It is custom-written and is deployed sparingly, in quantities lower than antivirus vendors’ thresholds for signature creation. Once the attackers have a foothold in a utility network, they scan for passwords or for Windows password hashes, which are generally easier to find and are almost as useful. With a domain administrator password or password hash, the attackers log into the Windows domain controller and create their own accounts and their own passwords. After this, they can simply log into and operate corporate network computers and even control sys-

tem computers remotely. Common RAT tools available on the black market are equipped with a wide range of attack features, including the ability to execute commands remotely, download new versions of the attack software itself and operate compromised machines remotely. M2M implications Once this happens, remote attackers are well positioned to interfere with M2M communications used to connect control and supervisory control and data acquisition (SCADA) systems to pumps, valves and sensors throughout water operations. In some utilities, interfering with M2M communications is as simple as opening a connection to the affected controllers and sending Modbus/TCP commands. In other utilities, M2M communications may be secured using encryption. However, encryption is only effective in defeating man-in-the-middle attacks. Modern attacks generally do not use such methods. Instead, hackers

compromise the endpoints of encrypted connections. For example, breaking into a SCADA input/output controller provides the attacker with access to the same encryption keys the controller uses to encrypt M2M communications with remote devices. This negates any protection encryption might offer. Another classic solution to secure M2M communications is fir walls. For decades, fir walls were sufficient enough to mitigate everyday threats. But now, anyone with a basic level of cybersecurity training understands the fundamental limitations of fir wall technology and knows how to exploit them. For example, because fir walls permit interaction between clients from outside a protected network and servers within, it is easy to disguise bad requests as legitimate traffic. This is the foundation of modern “fuzzing” attacks. The fundamental problem is that encryption, fir walls, antivirus systems, and all of these classic security measures are software security mechanisms. continued overleaf...

System Security All software has bugs, some of which are security vulnerabilities. In practice then, all software can be hacked, even security software. If anyone needs proof of this, simply visit any software security vendor and count how many security updates the vendor has posted recently. The real question is which pump, valve, pipeline or other piece of equipment is expendable enough to be worth defending with only software? The answer, of course, is none. Compromising a control system component or network has larger repercussions than a simple file leak or password theft. Such compromise provides control of equipment to a malicious party with unknown motives. For water and wastewater treatment facilities, the consequences could be anything from underground infrastructure damage, to pump and valve damage, to contaminated drinking water. Connecting “everything to everything” is the mantra of the “Internet of Things,” and such connectivity indeed promises real benefits in terms of cost

reduction and improved service levels. However, connecting everything directly or even indirectly via other networks to the Internet, provides intruders with all of these remote-control attack opportunities as well. Evolving best practices As attack techniques continue to become more sophisticated, so must defenses. The foundation of modern operations cybersecurity is network segmentation. Water control systems have notoriously “soft interiors.” Safety and reliability imperatives mean that the widespread use of plain-text M2M device communications and limited use of antivirus signature updates and other security updates will never go away. Control system networks will always be easier targets than corporate networks. The problem is that even for utilities where the water operations network is separate from the corporate network, the two tend to be interconnected. Water utilities benefit enormously from the collaboration between control systems

and business networks. This collaboration increases employee productivity, gives managers a direct line to minute-by-minute equipment outage and water quality priorities, and facilitates upgrades and maintenance. While it’s certainly possible to operate water facilities without integrating information technology (IT) and operations technology (OT) networks, the benefits of connectivity are simply too great. The vast majority of communications between IT and OT networks is “outbound” from operations to corporate. Modern segmentation focuses on the control of data returning into protected networks. It fosters a deep suspicion of absolutely everything that enters a protected operations network through any mechanism. This means being suspicious of everything from virtual private network-based remote access, to inbound encrypted communications, to third-party supplier software, and to every laptop or flash drive that interacts with the network. There are a host of modern technol-

System Security ogies to support best-practice segmentation. Unidirectional security gateways are hardware-enforced technologies that allow data to leave operations networks without allowing anything back in. They replicate industrial servers to corporate networks in real time. This allows corporate users and applications to query the replicas for real-time data and receive the same answers as the sensitive, production servers would have provided. FLIP technologies are reversible hardware gateways. They are designed specifically to allow control signals into protected remote stations without permitting the interactive remote control or â&#x20AC;&#x153;fuzzingâ&#x20AC;? that is the foundation of modern attacks. Application data control filtering provides an extra layer of security policy enforcement, allowing control over which tags, values and commands are allowed into protected equipment. In addition, USB device control software prevents USB storage devices, such as flash drives, cell phones and tablets, from being mounted on control

system equipment. All of these devices can propagate malware just as easily as fir walls do. Stand-alone kiosks at physical security checkpoints provide a way to scan media being carried into protected networks. Network Access Control technologies prevent the connection of arbitrary computers and laptops to protected networks, such as might occur when contractors visit the site, or when potentially-infected new or re-purposed computers are brought into control system sites. Utilities that deploy this strategy report that they are able to expose their networks to external data and to external attacks less and less frequently. For example, with remote screen view technologies, support personnel can see the screens of critical machines and participate in emergency troubleshooting without ever sending any mouse movement or other command into a protected network. Over time, these sites also build up a small number of operations laptops, pre-provisioned with all software that

contractors and other suppliers need while on-site. No third-party laptop need ever be permitted a connection to an operations network. Deploying hardware-enforced, stronger-than-fir walls protections at network perimeters, in tandem with technologies and procedures to control the use of removable media and mobile computing devices, can dramatically reduce the effectiveness of modern attack methods. Not only do secured water utilities continue to realize business efficien y gains due to IT and OT integration, they can safely and securely do so without putting operations-critical assets, equipment and even public safety at risk. A truism of cybersecurity is that attacks always become more sophisticated over time. Utilities and networks must continue to evolve and deploy cybersecurity best practices, in order to defeat them.

Brewery wastewater treatment system relies on its pumps

he craft brewing industry has grown an average of 10.9% over the last decade. With burgeoning enthusiasm from consumers, it is no surprise that breweries are expanding their operations to meet the increase in demand. To do this successfully they must use reliable equipment. An efficient treatment system was required to process the wastewater generated by one particular brewery. ClearBlu Environmental designed the pretreatment system, which included screening, settling and pH balancing, as well as the pond design, aeration system, bacterial treatment and final-stage fl w monitoring. It was determined that three lift stations would need to be installed, with two pumps to operate in each lift station. Three main challenges affected submersible pump selection for the primary lift station: 1. Acidic wastewater. With a pH of 4,

ClearBlu Environmental selected two submersible pumps to be installed in a duplex arrangement.

the brewery’s wastewater was highly acidic. The majority of submersible pumps are made from cast iron, which would not last in this environment. 2. High temperatures. The brewery’s wastewater was consistently over 60oC. Many submersible pumps cannot withstand liquids at temperatures higher than 40oC. 3. Solids handling. As with any brewery or winery, the wastewater con-

tains solids that could potentially erode pump components or clog the pumps, thereby reducing pump reliability and risking operational delays. ClearBlu Environmental selected two BJM Model SX22CSS-F submersible pumps to be installed in a duplex arrangement within the cylindrical fiberglass primary lift station. Since their installation in June 2013, the pumps have performed reliably, operating at 460 volts and pumping up to 1,000 litres/minute. Flow control within the system helps regulate the amount of brewery wastewater that travels to the town’s wastewater treatment plant. This ensures fl w is spread out evenly over a 24-hour period. The lift stations have been kept clear of settled solids and have not overfl wed. For more information, visit www.bjmpumps.com

Wastewater Treatment

Using IFAS for improved WWTP capacity and performance By Valera Saknenko, Vincent Nazareth, Roberson Gibb, Patrick Devlin and Krista Thomas

he Peterborough Wastewater Treatment Plant (WWTP) in southern Ontario is a Class IV plant discharging to the Otonabee River. As a result of municipal growth, average capacity had to be increased from 60,000 m3/day to 68,200 m3/day, with a simultaneous improvement in effluent qualit . This plant re-rating was achieved by full conversion of the existing aeration tanks to a hybrid integrated fi ed film activated sludge (IFAS) media system. Concurrent upgrades included improvements to the inlet works, construction of four new primary clarifiers, a sludge dewatering facility and a new septage receiving station. Since September 2011, it has been operating as an IFAS plant, resulting in a number of process benefits, including lower average total ammonia nitrogen (TAN), non-toxic effluent, and greater resiliency of the nitrification process to both organic and hydraulic shock loads. Nitrogen transformation To effectively evaluate the impacts of the IFAS system, it is important to first revisit some chemistry theory to appreciate the transformation process that occurs inside one. The majority of nitrogen enters wastewater in the form of urea and fecal matter, and is then converted through hydrolysis to TAN. TAN (or more correctly TAN-N, which measures only the mass of nitrogen) is the sum of two molecules: NH3 (ammonia or un-ionized ammonia) and NH4+ (ammonium or ionized ammonia). In essentially all solutions, including wastewater, both the ionized (NH4) and un-ionized (NH3) forms are present due to the principles of acid dissociation. The un-ionized form is the compound that is most toxic to fish. Fortunately, for aquatic species, at pH levels in typical wastewater, NH4 is present in much greater concentrations than NH3 (100:1 ratio at pH of 7.4). However, the NH3 percentage rises with increasing

pH and/or sewage temperature. This means that, for identical TAN measurements, warmer effluent results in greater toxicity due to the higher NH3 levels. To limit un-ionized ammonia effl ent concentration, TAN must be reduced through a two-step bacteriological conversion process (known as nitrification) during secondary treatment. Ammonia is first converted to nitrite (N02) using Nitrosomonas bacteria. Subsequently, the nitrite is converted to nitrate using Nitrobacter bacteria. The first process (conversion to nitrite) is the rate limiting process, meaning that nitrate is usually present in much greater concentrations. For aquatic species, the rate limiting reaction is critical, since nitrite is toxic at significantly l wer concentrations. IFAS overview An IFAS system is capable of improving the resiliency of conversion of TAN to nitrate within a WWTP. The IFAS system comprises fi ed or floa ing media, placed within an activated sludge tank to augment the number of nitrifying bacteria. The IFAS system takes a hybrid approach to nitrification. It uses traditional mixed liquor suspended solids (MLSS) within the aeration tank, as well as biofilm attached to plastic media, to promote the development

of additional nitrifying bacteria. A primary advantage of IFAS, versus a traditional activated sludge system, is the ability to create a higher biomass in the aeration tank by providing a surface for bacteria growth to aid the process. This additional biomass is retained in the tanks, thereby maintaining acceptable solids loading to the secondary clarifiers. A significant percentage of the nitrifying bacteria are kept within the aeration tank attached to the biofilm. This contributes to the conversion of ammonia to nitrate, without a proportional increase in MLSS concentrations. The solids retention time (SRT), and, therefore, aeration tank size, can be reduced for a given level of nutrient removal. This makes the IFAS technology attractive for the following retrofit applications: • Increasing plant capacity, while maintaining existing effluent requirements; • Meeting more stringent effluent criteria imposed on a WWTP within the confines of the xisting tankage; • Providing biological nitrogen removal (denitrification) by partitioning an existing tank to contain both an IFAS aerobic zone and a separate anaerobic/anoxic zone. The fi ed biofilm also provides other

Wastewater Treatment inherent benefits to increase the resiliency of the nitrification process. Fixed media provides better nitrification in cold climates, and the biomass population is more resistant to both organic and hydraulic shock loads. Fixed biomass attached to free floating media provides a seeding source to re-populate biomass after a fl w surge through secondary treatment. Preliminary and primary treatment at the Peterborough WWTP consists of mechanical screening, aerated grit tanks and primary clarification. Secondary treatment is provided through two parallel IFAS treatment trains and horizontal secondary clarifiers, referred to as Plants One and Two. Prior to discharge into the Otonabee River, secondary effluent is disinfected using UV irradiation. Unit process sizes (bioreactors and secondary clarifiers) in the two plants are marginally different. Primary and waste activated sludge are stabilized in two primary anaerobic digesters (2,444 m3 each) and two secondary digesters (1,445 m3 each) and dewatered using centrifuges.

Discharge effluent requirements for the Peterborough WWTP are provided in Table 1. TAN reduction is a prescribed effluent objective. There are no total nitrogen or nitrate limits imposed on the effluent, negating any denitrific tion requirements. Each aeration tank was retrofitted with a non-proprietary IFAS system. One metal cage per plant was installed with a fine perforated metal mesh elevated above the diffusers. This prevents media from settling when the tank is taken out of service. The cages were installed in the front half of the first pass of the three-pass aeration tanks. Air

lances were added to assist with media circulation. Approximately 190 m3 of media was added in each aeration tank. The plastic media used was not engineered specifically for IFAS systems, but rather regular packing media with total specific surface area of approximately 210 m2/m3. Although this media may not be as effective as engineered media specifically designed for this type of application, it has proved to be sufficiently e fective.

Wastewater Treatment nitrification at the WWTP, monthly average TAN effluent concentrations were compared for time periods when the plant was operating with and without IFAS. Data indicates that full implementation of the IFAS system at Plants One and Two has had a significant impact on stabilization of the nitrification process. As can be seen from Figure 1, after installation of IFAS, fluctuations in fl ws did not produce the TAN concentration exceedances observed prior to the retrofit. For example, high fl w events in 2005, 2008 and 2011 prior to IFAS resulted in significant wash out of MLSS, including nitrifiers. This resulted in long recovery periods (about six months) before TAN effluent concentration dropped below the effluent objective. After IFAS implementation, similar high fl w events in March 2012 and April 2013 did not cause significant effluent TAN spikes. It is noted that a minor spike in TAN occurred in the late summer of 2013, corresponding to the time period when one aeration tank had to be taken out of service. Other effluent indicators also validated performance of the IFAS system. Cross referencing effluent un-ionized ammonia concentrations showed a parallel decrease and stabilization of toxic un-ionized ammonia. This is to be expected since un-ionized ammonia is a direct function of TAN concentration, pH and temperature. Further validation was completed by confirming the increase in effluent nitrate levels after the IFAS implementation. As per the nitrificatio chemistry described earlier, nitrate levels are expected to increase as nitrificatio improves. Seasonal aggregates of the average TAN concentrations shown in Figure 1 substantiate the fact that IFAS provides considerable advantages over a conventional suspended biomass process during the coldest seasons. For the period of January through March, effluent total ammonia levels were 30% of the comparative period when the WWTP was operating without IFAS. The impact of IFAS was less during the warmer months, with effluent TAN levels being 70% of pre-IFAS conditions. A review of the annual maximum 40 | January/February 2015

peak daily TAN effluent concentrations gathered from daily samples shows a similar ability of the IFAS system to attenuate peak TAN levels. As shown in Table 2, the maximum recorded TAN levels dropped by 60% after implementation of the full-scale IFAS. Summary Upgrading the Peterborough WWTP with an IFAS system allowed maximum use of the existing infrastructure and increased efficien y by augmenting the total amount of biomass in the system. This approach eliminated the need to build new aeration tanks and secondary clarifiers, saving some $13 million in construction costs.

Converting the secondary treatment train to IFAS has lowered average TAN to 1.25 mg/l (37% of original levels) and resulted in a corresponding reduction in un-ionized ammonia. It achieves its greatest efficien y during the coldest winter months. Operators have noted that the ammonia reduction in the “IFAS Zone” has been approximately 80%. The food to micro-organism ratio (F:M Ratio) has changed from 0.4 to 0.28-0.30, leading to a decrease in return activated sludge. Effluent total suspended solids and carbonaceous biochemical oxygen demand have continued to be below effluent limits. Long-term effluent results demonstrate the potential for IFAS to be successfully used in retrofits to increase plant capacity, meet more stringent effluent criteria, or to increase rated capacity to maximize existing tankage volume use within the secondary treatment train.

Organic Waste

Dry phase anaerobic digestion of organic waste: closing the loop on energy and nutrients By Christian Cabral

here is currently a strong movement in North America to prevent landfill disposal of organic waste. As a result, many municipalities and private companies are seeking diversion solutions to comply with bans and avoid fina cial penalties. In each case, the solution must address specific social, economic and environmental aspects. To add to the challenge, alternatives must be projected 30 to 50 years in the future. This requires consideration of future environmental policy, economic context, energy values, carbon footprints and nutrient management. If energy recovery is part of the organics recycling strategy, two well-proven routes are available: thermal processes and anaerobic digestion (AD). This article will explore the benefits of continuous, plug-fl w, dry or high solids AD as an appropriate solution for many Canadian cities. To digest or not to digest There are good reasons for the municipal and private sector to look at AD of municipal organic waste: 1. Power companies are increasingly looking to diversify their offerings, accommodating clean energy as part of their portfolio. 2. Anaerobic digestion can significantl help downstream composting platforms by minimizing maturation time, increasing capacity, controlling odour and wildlife nuisances and preventing pathogen vectors. 3. Provinces are looking at biogas to help offset fossil fuel demands. 4. Organics landfill bans prevent raw organic waste from disposal in landfill cells. However, stabilized residual organics, in certain cases, may be used as landfill cover after AD and/or composting. Depending on feedstock quality, processing organic waste can be challenging. Starting at waste containers, there are two basic avenues to recycle organic waste:

44 | January/February 2015

152 JF.15_Dry Phase Anaerobic.indd 44

Typical dry source segregated organic waste processing installation.

• Collection of source segregated organic waste (SSO), followed by treatment at a composting site or energy producing AD plant or combination of the two. • Collection of mixed municipal solid waste including organic wastes, followed by mechanical separation of any recyclables at a mechanicalbiological treatment (MBT) plant. The organic fraction of municipal solid waste is then either composted, or anaerobically digested for energy production. Both organic recycling avenues have their strengths and weaknesses. While source segregated collection requires high participation rates and separate collection and transport logistics, the resulting organic waste stream is typically “clean.” This means it contains a limited amount of impurities such as plastics, glass, metals and debris. Therefore, it is possible to produce higher quality fertilizer products with greater reuse potential. For MBT plants, waste producers

have it easy and no additional collection and transport logistics are required. However, substantial technical efforts are required at the sorting plant. This leads to far more impurities that “spoil” the subsequent treatment process and typically require additional post-treatment to satisfy regulators and users. The optimum route depends on the waste source and ease of separation. Continuous plug-fl w dry anaerobic digestion For both waste collection avenues, dry AD technology plays an important role in the processing of organic waste to energy and fertilizer. Dry AD technology can process many mixtures of organic material with average dry matter contents of 20% to 50%. These “solid” waste streams would need to be diluted to be processed in larger volume “wet” AD reactors with dry matter contents of less than 15%. These wet systems, although designed as fully stirred reactor tanks, are subject to solids accumulation over time and related shutdowns to maintain active

Environmental Science & Engineering Magazine

Organic Waste volume. Wet AD systems are typically designed for liquid or pumpable slurries and manure, wastewater treatment plant sludge, or liquid effluents from food or beverage producers. Veolia has extensive global experience operating various AD, composting and MBT plants. Continuous thermophilic (53-55°C) AD technology employing horizontal plug-fl w has proven to be particularly robust and efficient. This process type achieves a nearly perfect conversion of degradable organic matter into biogas, maximizing energy yield. Thermophilic AD also kills pathogens, seeds and germs in a very compact reactor. In contrast, non-continuous or batch dry AD processes are not completely closed, potentially releasing both odours and methane gas. In terms of efficien y, batch dry AD processes may lose part of the methane while percolating, since only the organic “juices” are digested. This results in undigested organics attached to residual solids and explosion risks due to an oxygen rich environment.

The Kompogas® process In 2012, Veolia Water Technologies Canada started to look for an appropriate technology for high solids AD applications. The selection criteria were: availability, efficien y, simplicity and safety. The Kompogas plug-fl w AD best met these criteria, and has two decades of proven operation with over 75 installations. A wide range of input materials can be processed in a Kompogas reactor module, such as: • Bio-waste and food leftovers from households. • Food waste from commercial caterers, including oils and fats from restaurants, cafeterias, etc. • Unpacked organic waste from supermarkets and industrial food processors. • Green waste from private yards and public works. • Organic fraction of municipal solid waste. This modular solution has a standard design and processing train for most

SSO applications. The source segregated mixture of green and food waste is processed inside a building with slight negative air pressure and exhaust air treatment. In the pretreatment and intermediate storage areas the organic waste is shredded to a particle size of 50-60 mm, sieved and stored. From this intermediate storage the digester module is fed continuously with the pretreated material. The organic material is fed to the horizontal AD reactor with a plug-screw or pump at one end. A longitudinal agitator device turns slowly inside the digester, degasifying the digesting substrate. At the same time, layering within the substrate and sedimentation of heavy particles is prevented, thanks to the specially positioned agitator paddles. The substrate passes through the reactor in a plug-fl w regime. After anaerobic degradation, biomass (digestate) is pumped out of the opposite end of the module for further processing.

Organic Waste cro-organisms efficiently degrade the organic material inside the digester, releasing over 95% of its energy potential in the form of biogas. Biogas is a mixture of roughly 55% methane and 45% carbon dioxide, with some trace gases. Two principal methods are used for downstream digestate processing: 1. Dewatering to produce a liquid fertilizer accounting for normally around 50% of the throughput, and producing an anaerobic compost. The stabilized compost may have to be screened for foreign matter depending on feed organic waste quality. The liquid digestate can be stored on-site until fertilization season. 2. Mixing the digestate directly with structurant, which includes bypassed organics, fibers, excess green waste and recycled residuals. In this case, no dewatering or liquid storage is required. The composting platform has, however, to account for proper curing and maturation time as well as any seasonal storage. This post mix strategy is very common in Europe on existing composting sites with odour and/or capacity challenges.

46 | January/February 2015

152 JF.15_Dry Phase Anaerobic.indd 46

The AD processing facility can stabilize fresh organics faster in a controlled environment and double the capacity of composting platforms that act as final maturation and storage platforms. This can be an upgrade strategy for composting sites, which have similar issues and want to minimize residual liquid management. Frequently asked questions There are a few misconceptions about AD of organics waste in general and plug-fl w thermophilic AD specifically. The most common ones are:

Q A

Are thermophilic dry AD processes sensitive to biological upsets?

The process is designed to handle significant variation of waste and loads, as system feed can be adjusted over an extended period of time. For instance, the process can accept a significant ratio of yard waste as expected in Canada. Most AD upset risks in source separated organic waste applications relate to ammonia inhibition. An ammonia

concentration limit of 2.8 g/l in the reactor is recommended, but there are systems operating successfully at higher concentrations due to micro-organism adaptability. Excess meat or fish protein waste may introduce a higher nitrogen input. Since it normally takes weeks to impact the overall system, volatile fat acids measurements and biogas quality give an early indication of trouble. The solution is to balance the nitrogen to carbon ratio in the process, for example by increasing plant matter waste. Toxicity is very uncommon when feedstock is household waste. A small fraction of contaminants is typical and may include batteries, low/high pH liquids, residual cosmetics or cleaning products. In the case of institutional, commercial and industrial inputs, heavy metals, biocides and acids must be avoided.

Can anaerobic digestion destroy organics and therefore reduce mass to compost?

Mass reduction in an anaerobic reactor is generally around 15%.

Environmental Science &â&#x20AC;&#x2C6;Engineering Magazine

2/1/15 10:03 PM

Organic Waste AD degrades organic matter to biogas at a rate of 110 â&#x20AC;&#x201C; 150 Nm3/tonne). The digestate has low biological activity, meaning nearly all of the anaerobically degradable matter has been converted into biogas. The main function of the composting platform downstream (or dewatering) is to transfer the material from anaerobic to aerobic conditions and to reduce the water content which, in turn, will significantly reduce final mass.

Q A

Is plug-flow high solids digestion costly to operate?

Typically, a plant of 25,000 tonnes per year of source segregated organic waste would produce approximately 750 kW of electricity using the Kompogas process. The plant would consume 10% to 15% of the reactor`s electricity production and 20% to 30% of its heat production. These plants are manned fi e days a week by three operators during the day. Nighttime operation is automatic.

www.esemag.com

152 JF.15_Dry Phase Anaerobic.indd 47

Reactors have been operated for more than 20 years with minimal component replacement costs. As an example, the slow moving paddle mixer relies on an 11 kW motor and has all assembly components accessible from outside the reactor.

Q A

Can high solids AD affect the quality of the final compost

Anaerobic digestion will not affect the quality of the final product in regard to contaminants (plastics, glass, and metals) but the processing steps before and after digestion will. The level of pretreatment or final compost polishing will be based on the feedstock quality and the intended fraction of quality compost expected. The same challenges in regards to final product quality are found on composting platforms without AD and similar processing equipment would have to be used. Most of the AD installations in Europe produce a high fraction of quality

compost from typical source separated. Both Veolia and Kompogas have extensive experience with AD and/or composting of organic municipal solid waste. In these plants, pretreatment will typically segregate 45% of the mixed waste as feedstock to convert into energy. From that approximately one-third becomes quality compost. Summary Canada is leading the way in North America in respect to organic waste recovery. Certain provinces implemented source separated programs in the 1990s and most have organic recycling as part of their waste management strategy. Plug-fl w thermophilic anaerobic digestion technology further increases the benefits of organic waste diversion, efficiently closing the loop on energy and nutrients, while avoiding landfilling useful resources.

he 780-foot Palace of Culture and Science overshadows the skyline of Warsaw. Built in 1955, the sprawling tower, a “gift from the Soviet people to the Polish nation,” was built among the ruins of the city and was the second tallest building in Europe at the time. For residents, the tower exemplified the power and dominance of Soviet rule and communism and they referred to it with distaste as the “elephant in lace” and “Stalin’s syringe.” Today, modern steel and glass skyscrapers ring the city centre, vying for attention and prestige with the Palace. The latest car models and Tommy Hilfiger are advertised on immense billboards. Such is also the way of Poland’s environment and industry. Left with a toxic communist legacy, the country is now racing to catch up with European Union regulations and clean technology. Funded by a number of EU programs designed to close the

infrastructure gap between Poland and the EU, the country has invested heavily. The Operational Programme: Infrastructure and Environment (OPI&E) is the largest of these programs in Poland and one of the largest in the EU. Approximately $38 billion is being invested into transport, environment, energy, education and culture. Wind turbines have been built, biogas digesters constructed and highways laid down. The emphasis on clean energy production has allowed air quality to improve despite economic development and increased vehicle use. However, Poland still faces high ozone, nitrogen dioxide and air particulate pollution. Standing on the viewing platform at the Palace of Culture and Science, the red and white painted flues of coal plants surrounding the city are visible through the haze. The investment and push for clean water, air and energy has created opportunities which companies are keen to capture. Hundreds of exhibitors and nearly 14,000 attendees gathered in the city of Poznan to attend Poleko 2014: International Trade Fair of Environmental Protection. The event has run for 26 years and attracts big European companies in environmental, municipal and energy industries. Waste in all of its forms, uses and liabilities, was the predominant topic at the show.

waste generated in Poland and Europe. At a small plant and storage yard outside Warsaw, workers disassemble electronics into their smaller components, separating plastics, metals and circuit boards. In another building, a pilot project is being conducted to chemically extract precious metals and rare earth minerals from circuit boards. Most promising, the company said, is the recycling of used battery components. Large numbers of batteries are discarded, yet they can be salvaged and sold to manufacturers for reuse. Polblume owner Zbigniew Miazga, said he hopes to eventually be processing 10,000 tonnes of used batteries collected from across Europe. On a larger scale, the recently built Warsaw wastewater treatment plant is one of the largest in Eastern Europe. When Poland joined the EU in 2004, only 30-40% of the municipality’s wastewater received primary treatment. The $640 million plant was designed and built by a consortium including Veolia Water, Vinci Construction and WTE. It brings Warsaw up to EU discharge standards and has a treatment capacity of up to 515,000 m3/day. The Warsaw WWTP is an example of the large-scale investments and infrastructure projects occurring in Poland. In the City of Łódz (pronounced “Woodge”), a special economic zone has been set up to attract investors and combat high unemployment. Once known for its textile industry, sprawling red brick factories now lay abandoned and crumbling. The economic zone’s corporate tax breaks, state aid and infrastructure improvements, have brought in a number of large well known companies including Gillette, Flextronics and Fujistu. The zone’s headquarters and rented office space now occupy a remodeled textile mill, grafting steel and glass to historic red brick. Despite a tragic history punctuated by atrocity and rule by European powers, and the legacy of a command economy, the vibrancy and energy of Poland is immense. Cranes have sprouted up among the drab blocks of apartment buildings, building office towers and condominiums. Young people throng the streets, speaking easy English to each other and tourists. As it races to catch up with European standards, economic and environmental growth seems to be pulled along. www.esemag.com

Water Supply

Pressure management project cuts water losses by 75% By Brad Clarke

alang City lies 900 km east of Jakarta on Java Island, Indonesia. In 2011, it was supplying water to some 120,000 service connections, amounting to roughly 600,000 people. This accounted for about 70% of the city’s population. Roughly 30% of the supply is gravity fed directly from springs and 70% is pumped to eight storage reservoirs, with a total maximum storage capacity of 18,000 m3. However, there was a lack of water supply and low reservoir levels due to leakage and pipe bursts. Thirty per cent of the population was regularly deprived of water. In 2009, with daily pipe bursts, reservoirs dropping to 20% of capacity at night and leakage rates hitting an estimated high of 41%, or 400 litres/ second, Teguh Cahyono, the Director of Non-Revenue Water (NRW) for the city’s water department, PDAM Malang, brought a team of experts together to create a water loss management plan. Ranhill Water Services, a Malaysian NRW consulting firm, conducted a six-month district meter area (DMA) hydraulic calibration study for roughly 20% of the PDAM Malang water distribution system. The consensus was to develop numerous control zones or DMAs with a single water source, using a meter and a pilot-operated control valve at the source of the DMA. Once fl w into the DMA can be measured, as well as fl w to users, then pressure can be managed. There is a direct correlation between pressure and leakage. If you reduce pressure you will reduce leakage. The ultimate goal is to give clients just enough pressure to serve their needs, while eliminating over pressure. One of the most difficult aspects of the project was getting senior PDAM Malang City water directors and politicians to approve the budget and necessary funding for such an ambitious plan. To demonstrate that the goals were achievable and that the return

on investment (ROI) would be there, PDAM Malang installed three test DMAs and pressure reducing valves (PRVs) near a problem reservoir. The pipe bursts stopped, leakage was greatly reduced and reservoir levels were maintained. The directors were convinced and so the budget requirements were approved and the project moved forward at a rapid rate. DMA construction began initially with 42 Singer Valve S106 2PR-BT (100 mm – 500 mm) units being installed. In Malang City, the average pressure in the main distribution lines ranges from 2 bar (30 psi) to 4 bar (60 psi). In order to reduce this, Singer added two pressure reducing pilots to the main diaphragm-operated control valve. One pilot is set lower for night pressure (low demand) and the other is set for daytime pressure (high demand), so they are able to relatively accurately maintain pressure at the critical point. This is typically the most challenging

pressure point in the DMA. This technology is controlled by a simple IP – 68 timing device, using a locally available 9 volt battery that switches pressure at a predetermined time. The new valves were able to reduce pressure during high demand in the daytime to 2 bar (30 psi) and further reduce the night pressure to 1.5 bar (22.5 psi). As of mid 2013, leakage had been reduced from 41% to 27.7%. In terms of volume, this meant leakage had been reduced from 400 litres/second to 250 litres/second. An additional 96 Singer pressure reducing valves were installed in 2013 to reduce leakage to 20%. This represents an overall saving of 750,000 m3/month, which is a 75% reduction. Larger valves were required for larger main DMA areas. These valves have a unique single rolling diaphragm (SRD) as opposed to the norm of fla diaphragms that often have seat chatter with fluctuating fl w. The SRD pro-

Environmental Science & Engineering Magazine

Water Supply vides smooth, steady and precise pressure control from maximum to virtually zero fl w without the need for lowfl w bypass valves. The effective area of a single rolling diaphragm remains constant and the bonnet is much smaller and lighter than a flat diaphragm version. A measured quantity into the bonnet control chamber always gives the same smooth movement of the inner valve through the entire stroke, even at low fl ws (nighttime). A smaller bonnet also makes the valve lighter and safer for maintenance, while the control chamber enables it to respond faster to changing pressures. This NRW-specific innovation prevents minor surges entering the downstream side of the PRV. Prior to the installation of the first 42 valves, Malang had an average of one pipe burst per day. This has been reduced to an average of one pipe burst per month which has led to huge savings in the annual maintenance budget. In addition, the entire system makes use of geographic information system (GIS) technology, allowing for real time monitoring of pressure and fl w, so that leak detection teams can be dispatched to specific DMAs when data readings are unacceptable. Prior to the PRV installation, reservoir levels typically dropped to about 20% of capacity by 4:00 a.m. each day, due to leakage rates and pipe bursts.

This resulted in extreme water shortages and sometimes no water for those at the ends of the distribution lines. Now, the city has reservoir levels at 80% at 4:00 a.m., resulting in the vast majority of customers in the DMA zones always having water. With increased reservoir capacity and greatly reduced leakage rates, the city has been able to expand its distribution main lines and make water available to an additional 125,000 people. From June 2012 to June 2013, they added approximately 1,000 new service connections a month to cus-

tomers who had no reliable access to the city’s water because there simply was not enough. There has also been a 33% saving in power consumption. Prior to the installation of the new pressure reducing valves, two pumps were required to supply the reservoirs. Due to the increased capacity of the reservoirs, only one pump is now required to maintain the levels, despite the additional customers. Brad Clark is with Singer Valve.

Lessons learned from successful applications of biological landfill leachate treatment By Sara Arabi and Andrew Lugowski

Figure 1. Schematic flow diagram of the Green Lane leachate treatment facility.

andfill leachate treatment is a major engineering challenge due to the high and variable concentrations of dissolved solids, dissolved and colloidal organics, heavy metals and xenobiotic organics. Specific leachate management practices, such as recirculation (bioreactor landfill) and blending landfill gas with leachate, impact quality, resulting in characteristics that vary greatly from site to site. Cold temperature in winter is also a challenge to designing leachate treatment facilities (LTF) in Canada. Traditionally, landfill leachate has been hauled or pumped to off-site wastewater treatment facilities for disposal. Disposal to off-site facilities has generated opposition from plant owners due to more stringent effluent discharge criteria. When discharged to a wastewater treatment facility, leachates can interfere with ultraviolet disinfection by strongly quenching UV light. Leachate may also contain heavy metals and high ammonia concentration that may be inhibitory to the biological processes. On-site leachate treatment is an alternative to the increasing costs associated

with hauling leachate to a local wastewater treatment plant. These treatment facilities are designed to fulfill the specific needs of individual landfill sites and allow discharge to a sanitary sewer or water body without any hauling or disposal costs. Technologies for landfill leachate treatment include biological treatment, physical/chemical treatment and â&#x20AC;&#x153;emergingâ&#x20AC;? technologies such as reverse osmosis (RO) and evaporation. Biological leachate treatment is a proven technology for organics and ammonia removal in young and mature leachate. The anoxic/aerobic processes achieve nitrification and denitrification and reduce the oxygen demand for landfill leachate treatment. Biological treatment methods include the activated sludge process (ASP), sequencing batch reactors (SBR), membrane bioreactors (MBR), aerobic lagoons and constructed wetlands. Physical-chemical treatment methods include oxidation, coagulation/flocculation, activated carbon, stripping, evaporation, filtration and RO. The choice of technology depends largely upon character-

istics of the leachate, discharge limitations (e.g., direct or indirect discharge), and site constraints. Green Lane LTF The Green Lane Landfill is located in St. Thomas, Ontario, and was originally opened in 1978 for the disposal of local residential wastes. The site currently accepts domestic, commercial and solid non-hazardous industrial wastes from a province-wide service area. Site capacity is approximately 5.7 million tonnes, and approximately one-quarter of this capacity has been utilized to date. With current landfilling rates and air-space limitations, the remaining site life is estimated to be 20 years. Extensive treatability studies were conducted prior to the design of the LTF, including respirometry tests to determine bio-kinetics and bench-scale coagulation/precipitation testing for colour removal. Coagulation and floccul tion testing was conducted to compare alum and ferric chloride with respect to the initial and final pH, dosage, sludge production and colour reduction.

proved to be useful in determining the feasibility of potential treatment processes for removing contaminants from the leachate. It also resulted in the collection of significant data for the full-scale on-site LTF design. The leachate was characterized by high COD (1,000 - 5,000 mg/l), ammonia (150 - 600 mg/l), total dissolved solid (TDS) (2,000 - 6,000 mg/l) and intense colour (up to 1,200 Pt-Co). A primary design criterion for the treatment plant was to incorporate significant fl xibility in the treatment

processes to allow for expected variations in leachate quality and quantity throughout the landfill site life and beyond. In order to reliably achieve the treatment required, the biological system was designed as Modified Ludzack-Ettinger (MLE) process for an extended retention time. Hydraulic retention time (HRT) was found to be required for hydrolysis of slowly biodegradable compounds in the leachate and to achieve low enough organics, prior to aerobic nitrification.

The full-scale LTF, designed at a capacity of 300 m3/day, includes pre-treatment comprising chemical addition and primary clarification to remove metals, hardness and TDS. The MLE process is followed by ozonation to remove colour, and filtration to treat leachate to acceptable regulatory levels for a surface water receiver. Phosphoric acid and methanol are added as supplemental phosphorus and carbon sources, respectively (see Figure 1). continued overleaf...

The contaminants of concern in groundwater were iron and manganese. The landfil owner decided to move forward with the design of a combined facility to treat the impacted groundwater, as well as leachate from ongoing landfilling act vities. Extensive bench-scale treatability tests were performed on the leachate to identify processes suitable for reducing iron. This included iron oxidation

Landfill by aeration and by strong oxidants, followed by precipitation. Biological process modelling was conducted prior to the conceptual design of the LTF. Treatability tests proved that iron oxidation by aeration is sufficient for the reduction of iron. Based on what had to be removed from the waste, it was determined that a chemical pre-treatment step was not required before biological treatment. Impacted groundwater and leachates are treated by a biological process designed to achieve nitrification and denitrification at a design capacity of 120 m3/day. The major challenge in the design of this LTF was the high variability of influent total Kjeldahl nitrogen concentrations (60-250 mg/l). In order to achieve stable operation in spite of highly variable carbon-to-nitrogen ratio, the overall LTF was designed for extended retention time of 2.3 days (anoxic and aerobic HRTs of 15 and 40 hours, respectively). Methanol and phosphoric acid are added as carbon and phosphorus sources. Effluent from the clarifier is discharged to the polishing pond and a

stormwater/infiltration pond. A major concern in operating biological systems in cold climates is the reduced nitrification performance or freezing, during periods of low ambient temperatures. Long-term effluent quality averages are: ammonia of 0.1 - 2 mg/l, and BOD of < 7 mg/l. These are lower than the respective effluent limits of 5 and 15 mg/l. The LTF achieved 99% ammonia removal for this period. Effluent nitrate concentrations were in the range of 22 - 47 mg/l, reflecting excellent denitrification. Iron and manganese in the impacted groundwater were reduced to Provincial Water Quality Objectives (0.3 mg/l iron) in the aeration system without pre-treatment. Summary On-site leachate treatment systems are an attractive alternative to reduce the cost and environmental risk of hauling leachate to off-site treatment facilities. Proper characterization of leachate, backed by treatability studies (bench tests or pilot studies) is helpful to select a reli-

able leachate treatment facility that can effectively accommodate variable influen characteristics. Applicable technologies for on-site leachate treatment include a variety of physical/chemical processes as well as biological processes. The two case studies describe the suitability of biological processes for treatment of young and intermediate leachate. Nitrification and denitrific tion processes for biological treatment of leachate have been successfully implemented for removal of organics and nitrogen. The advantages of such processes include stable nitrification, higher degree of total nitrogen removal, reduction of oxygen demand and lower sludge production rate. Provisions for addition of a supplemental carbon source, such as MicroC™ premium carbon sources or methanol and phosphorus, may need to be included for treatment optimization.

Understanding the role of protozoa in pathogen protection and proliferation

new study released by the AWWARF improves understanding of the role of amoebae in the protection and proliferation of pathogens in distribution systems. Although â&#x20AC;&#x153;amoebaeâ&#x20AC;? was used in the request for proposal (RFP), free living protozoa (FLP) is a more appropriate term that the research team used throughout the report. Strictly speaking, amoebae are only part of the FLP that interact with bacteria and are likely to be present in distribution systems. Considering all FLP gives a more complete picture. FLP are ubiquitous where bacteria, their main food source, are found. That they are present in distributed water is not a surprise. The types and numbers of active FLP in distributed water can relate directly to the quality and quantity of their food source. This may be present in infrastructure biofilms, and, perhaps to a lesser extent, in bulk water. Over many years, water has been implicated as a source of opportunistic pathogens in healthcare and community disease outbreaks, particularly for the opportunistic respiratory pathogens Legionella spp. and Mycobacterium spp. Epidemiological data, along with laboratory reports of pathogens resisting digestion by amoebae, replicating inside amoebae, and dispersed by amoebae, have raised the specter of FLP delivering pathogens throughout distribution networks. It is necessary to understand the true extent and importance of FLP and their interactions with bacteria in the field What are the most probable scenarios for FLP-pathogen interactions and where are these most important? How many and what types of FLP are found in distributed water? Are they found co-occurring with opportunistic pathogens in distributed water? If they are, does this imply direct interaction or simple co-occurrence? The epidemiological data strongly supports a role for premise plumbing in FLP-pathogen interactions. Under what

FLP may be present in infrastructure biofilms and in bulk water.

circumstances is this most likely to occur, and which sites are likely to be most impacted? If it is clear that specific FLP are implicated in supporting certain pathogens, how can they be controlled? Literature Review Interest in the interaction of FLP with opportunistic bacterial pathogens is growing exponentially. For this study, the main focus was on those areas most directly related to potable water and discussing those questions that are still unanswered. It was important to consider the source to tap paradigm rather than only isolated segments of the treatment and distribution train. In addition to potentially supporting the persistence, distribution, and/or replication of certain opportunistic bacterial pathogens, FLP almost certainly provide significan benefits to drinking water by removing/digesting bacteria in biofilms and bulk water. Though there has been very little attempt to demonstrate this in distributed water, it can be inferred from the proven role of FLPs in ecological studies

performed on surface waters or microcosms. This study attempts to describe the complexity of the FLP-bacteria (predator-prey) relationships that might exist in distributed water and in infrastructure. Informed speculation is also included where it adds to the overall picture and might explain some of the complexities involved. Occurrence Survey Three types of devices were used to collect samples from up to six locations in each distribution system. Participants were selected based on geographic location (south or north), disinfection method (chlorine or chloramine) and source water (ground or surface). The basic approach used a combination of direct examination and morphological reports, coupled with culture on bait bacteria to amplify viable FLP, followed by molecular techniques to identify them. Correlations with FLP Samples were tested with a commercial quantitative PCR kit specific for L.

Bench-scale feeding studies demonstrated that even if some strains of FLP from the laboratory can ingest the mycobacterium offered, they may not be able to digest it. None of the newly isolated strains would accept it at as food, usually encysting. Following ingestion, the ability of mycobacteria to remain in the protozoa for varying periods of time might facilitate their dispersal and temporary protection from adverse events even if they do not replicate. H. vermiformis appeared to be much more sensitive to chloramine than acanthamoebae. Both exhibit some, though incomplete, sensitivity to free chlorine levels likely to be found in distributed water. Experiments were conducted at different pH levels, but it did not appear to be an important variable, except possibly for acanthamoebae exposed to chloramine. Recomendations Protozoa and their interaction with pathogens is an important and expanding area of research that is of wide interest to public health within and outside the drinking water industry. To address this need, the researchers recommend that the drinking water industry conduct further research in order to: • Understand how the selective pressures operating in the treatment train affect the presence and amplification of FLP and opportunistic pathogens before and as the water leaves the treatment facility, i.e., with and without disinfection. • Understand if particular components (e.g., pipe materials, gaskets, condensers) of the distribution system, including premise plumbing, influence the presence and or activity of FLP and opportunistic pathogens. • Understand how hydraulic conditions at pipe walls and conditions at air-water interfaces affect FLP activities including feeding and replication. • Explore the relationship of L. pneumophila (and possibly Mycobacterium avium) with other protozoa in/ from natural systems (i.e., outside the monocultures used in laboratory

experiments) to get a better picture of which protozoa other than H. vermiformis are natural amplifiers of these opportunistic bacteria. • Explore the relationship between legionellae and mycobacteria as a function of specific and relevant interventions. • Clarify the exact relationship between L. pneumophila and H. vermiformis; in particular is it advantaged by presence at an air-water interface? • Understand the presence of opportunistic pathogens in distributed water especially L. pneumophila and H. vermiformis, by using molecular tools to detect potential amplification on filters and in plant effluent. • In association with local public health authorities, take a leadership role in educating consumers on the issues ofIdeal crop marks protozoa and opportunistic pathogens; this includes both institutional and industrial users as well as individual consumers, where the risks differ. • Since potable water is not the only component of the environment in which such FLP-bacteria interactions take place, utilities should develop effective communication strategies that go beyond potable water to place the problem in the real context of total environmental exposure(s). In addition to industry research, the report recommends that drinking water utilities recognize and accept that: • Along with bacteria, they will inevitably deliver some FLP to consumers because normal disinfection is unlikely to eliminate all FLP. • Conditions that reduce one group of opportunistic pathogens might tend to increase the other. So, how do you choose which is the lesser of two opportunistic pathogen groups? • The complexity of FLP-bacteria interactions is such that problems could be site specific. Premise plumbing is where FLP-pathogen interactions are likely to be highest, and the risks from exposure to them greatest. This is especially true in large complex systems that recycle hot or warm water. • “Free-Living Protozoa and Opportunistic Pathogens in Distributed Water (Project 4092) is available from The American Water Works Association Research Foundation. www.awwarf.org

Three LS400T+ units are in production and will see action in El Salvador, Honduras and Nicaragua. Honduran drill teams work more on the Caribbean side of Central America and face dense, volcanic gravel material, where stones can become too large for drag bits but not big enough for air hammers. “The expectation is that the LS400T+ will effectively use a driver roller cone bit to drill through that hard material,” Hough says. Each project is a collaboration of both Living Water’s in-field teams and U.S. teams. The full-time, in-field teams work within each country, educating communities and assisting with well site selection. They ensure wells are placed away from potentially hazardous areas, such as latrines, to avoid contamination. Site selection is a joint decision because Living Water wants the community to have the sense of ownership of the well. Hough said experience has shown that, without this, the well quickly falls into disrepair. Living Water trains teams to use the drills and networks with other organizations and churches to recruit volunteers.

Improving community life At the beginning of 2014, Living Water expected to make 290 trips to drilling sites in Central America and Haiti. Organization’s teams and volunteers have drilled roughly 1,200 water wells with Lone Star’s drilling rigs in El Salvador, Guatemala, Honduras and Nicaragua. Many communities rely on agriculture, such as sugar cane cultivation, as a major source of income. But aerial pesticide and fertilizer spraying runs off into major sources of drinking water, such as rivers, streams and shallow, hand-dug wells. With deeper wells, the villagers can access cleaner water and avoid ailments such as kidney failure, dysentery and amebiasis. About Living Water Since 1990, Living Water International has sent thousands of volunteers to help complete more than 10,000 water projects in Central America, Africa and Haiti.

Infrastructure Investment

Understanding the true value of infrastructure spending By Paul Smetanin

ntario is an important economic contributor to Canada. With over 38% of the country’s population living in the province, ensuring sustainable economic and social growth in Ontario is a priority for policymakers. Yet, Ontario’s future is at risk as it stands to buckle under its own weight, given its infrastructure stock has been facing increasing pressure since the 1980s. It is clear that important decisions about infrastructure investment in Ontario must be made, requiring the ability to navigate the complex world of stakeholders, resources, evaluation and execution. This system of evaluation must be both consistent and realistic and avoid the risks of inaction. Traditional economic analysis is often undertaken when the province has to evaluate crucial policies and investments. This type of analysis for a potential investment accounts for its direct impacts (immediate effects on the industries and firms involved in construction of new infrastructure) its indirect impacts (the effects upon industries that produce goods and services needed by the direct impact industries), and induced impacts (productivity benefits of the economy in terms of demand and output). This traditional method fails to take into consideration that any infrastructure investment has a much broader and nuanced “systems effect.” This is the complex, intricate, and often recursive relationships that exist between all agents in an economy and, in particular, the relationship between those agents and the environment in which they operate. The “systems thinking” framework acknowledges these interactions in order to understand a system, such as an economy, as more than the sum of its parts, but rather as the relationships among a mixture of entities that act upon one another with virtually infinite recursion. With this approach, stopping at in-

Infrastructure investment, productivity and wages are all intimately connected.

duced effects when valuating an infrastructure investment is shortsighted. In fact, the critical lapse in traditional thinking is that it cannot capture what is at risk tomorrow if an investment is not made today. The economic concept of opportunity cost is the dollar value of the next best alternative to a particular investment. Systems thinking valuation includes all of the jobs and other indicators of a well-functioning society that are preserved if the investment is made, and stand to be lost if it is not. It, therefore, serves as a fundamental differentiator of not just investment quantities, but investment types. The task of modeling every entity, their effects, the relationship of other entities to those effects, and every other aspect of a society is complex. However, it is possible, and failing to do so in the name of simplicity is not an option when the future of the well-being of Ontario is at risk. RiskAnalytica has developed an agent-based modelling platform that employs the systems thinking framework to find new solutions to these problems. RiskAnalytica’s agent-based modelling platform, Prosperity at Risk tracks over 50 million agents for all of Can-

ada. Agents include individual people, corporations and government bodies, with information on 1.2 billion of their attributes from demographic and financial data, including (but not limited to) all data available through Statistics Canada. The platform also includes a variety of processes, which range from personal consumption to import and export activity, borrowing and many more. Geographic information is also used by the system, including prices and other regional characteristics. By modelling each agent, their actions and their relationships against a non-agent environment, an evolving representation of our society unfolds from individual-level information to a systems-level network. Using agent-based modeling, RiskAnalytica was able to model the Region of Peel in Ontario from its current population levels through to its potential full build-out in about 50 years time. Infrastructure must be updated and maintained in order for it to sustain population and economic growth. In particular, Peel Region’s policymakers sought to understand the importance of the investment and its timing. This included analyzing whether or not to invest $4

Infrastructure Investment billion in water and wastewater management, whether a lesser investment would be more economical, and whether any investment was really necessary. Using a traditional economic approach, it was calculated that the Region of Peel could stand to benefit from a modest 9,500 employment years as a result of the $4 billion investment. When projecting the number of employed residents in Peel Region relative to the population at its potential full build-out, there is little difference between the effects of investing $2 billion, $3 billion or $4 billion in water and wastewater management. In the interest of maximizing return and minimizing cost, a rational decision-maker could justify investing as little as $2 billion of the proposed $4 billion. However, when considering the economic activity in Peel in terms of real gross domestic product (GDP), the contrast becomes much greater. It was demonstrated that a failure to invest in water and wastewater as the population grew would cause an economic collapse, with falling incomes and overall quality of life. In fact, the systems approach was able to capture a total investment benefit of 2.8 million employment years for the Region of Peel alone. This includes all of the potential years of employment that stand to be lost if no investment is made as the population grows and interacts with infrastructure. The systems approach extends beyond the immediate region of interest and assesses the benefits of Ontario infrastructure investment to all players, such as provincial and federal levels of government. In a different project that used the same agent-based modeling platform, it was shown that the federal government is such a significant fiscal beneficiary of Queens Park’s infrastructure investments that it is forcing Ontario into long-term fiscal deficits. The absence of federal investment accounts for 83% of the total infrastructure investment shortfall that concerns provincial politicians. Objectively put, Ottawa’s continued lacklustre interest in Ontario infrastructure allows it to benefit, while binding Ontario to an unhealthy economic infrastructure investment strategy. If balancing infrastructure returns

against the risks is an objective, then the federal government could move from its current level of about 0.5% of GDP to a 2% contribution (about $72 billion over the next 10 years). It will still enjoy 65% of the surpluses that accrue from Ontario infrastructure investments. Moreover, this adjustment would restore the ability of the province to generate surpluses of its own from these infrastructure investments. Infrastructure investment, productivity and wages are all intimately connected. Agent-based modelling shows that such an investment shortfall is penalizing the ability of Ontario’s youth to save about $345,000 over their working lifetimes. Ontario faces both opportunities and threats when considering its future social and economic growth. It has evolved into the country’s most populous province and an economic hub. The province must organize, plan and coordinate investment into its aging infrastructure in order to preserve and promote sustainable growth and quality of life.

While inappropriate investment in infrastructure can alter the fundamental trajectory of the province’s unfolding history, hesitation also leaves Ontario’s future at risk. The problem is complex due to a myriad of issues, ranging from divorcing investment in infrastructure from potentially political agendas, to the difficulty of measuring a particular investment’s value to society. In the spirit of an evidence-based dialogue, there is a case to be made for the way we think cooperatively and the way in which we choose to evaluate and, therefore, value a particular investment. While often taken for granted as a problem for traditional economics, our way of thinking must be refined and scrutinized lest we risk a miscalculation. A systems approach using agent-based modelling is a strong foundation for realistic evaluation of choices within an evidence-based framework.

However, as proven by the Hazen-Williams co-efficient of friction equation, the smoother surface of the new liner means overall fl w capacity is maintained. The structural lining project begins with mapping the internal plumbing system and camera inspection of drain and sewer lines. A plan is implemented to minimize disruption and the time line for work completion. Depending on the lining method to be used, pipes may be drained and/or air-dried. After testing for leaks, the pipes are prepared for cleaning. Roots and calcite are removed in order to return the pipe to its original functioning diameter. Removal methods may include jetting the lines or the use of pneumatic tools such as a scorpion cutter. Cast pipe may require additional www.esemag.com

Energy Savings

Improving building energy efficiency with sewage heat recovery By Terry Johnston

ince its development, Sewage Heat And Recovery (SHARC) has been utilized in a number of different applications, including multi-unit residential developments, a public theatre and a wastewater treatment plant. Contracts are in place for several similar and larger scale installations. SHARC can be used to preheat domestic water as well as to heat and cool buildings, while dramatically reducing demand for natural gas and eliminating cooling towers. Additionally, SHARC can be used in tandem with geo-thermal technology, while reducing the number of bore holes required. The system is completely odourless, and requires minimal quarterly routine maintenance, with an expected lifespan exceeding 40 years. Depending on the application, the heat recovery unit can also contribute up to an additional 4 - 10 Leadership in Energy & Environmental Design (LEED) points. The smallest SHARC costs around $300,000 with recovery pay back periods averaging two - fi e years. For some applications the period could be a matter of months. SHARC systems are custom tailored to building specifications and work with new and retrofit applications. Each unit includes detailed trending software to monitor all aspects of the system and its performance, while ensuring optimal efficien y. Seven35, North Vancouver International Wastewater Systems’ (IWS) first installation was at Seven35, a 60-unit urban townhouse development in North Vancouver, British Columbia. The average suite is 1,000 square feet and consists of one and two bedroom units. Seven35 received dual LEED Platinum and Built Green Gold certification, using the SHARC as the key sustainability feature. The system works by targeting the building’s energy-rich wastewater before it leaves the property. On average, the temperature of the wastewater is

20° C. It picks up heat whenever residents consume hot water, including showering, washing dishes and doing laundry. Normally this energy simply fl ws down the drain. Instead the heat is recovered and used to pre-heat clean domestic hot water. The Sewage SHARC system in Seven35 moves wastewater through a filte , which temporarily removes any solids,

before it fl ws across a specially designed heat exchanger. It then utilizes two water-to-water heat pumps to extract heat from the wastewater. The heat pumps preheat incoming domestic hot water to 52°C and 1,800 litres of preheated domestic hot water are stored in the mechanical room storage tanks. Flow meters, temperature sensors and electrical meters are installed throughout

the sewage heat recovery system in order to monitor and log system operation and the amount of energy used and recovered. Operating data The SHARC control system has collected data for the past two years that the Seven35 building has been occupied. The sewage-holding tank was closely monitored and it was found that there was no buildup of solids or surface coatings inside the tank. There has been almost no down time and limited simple scheduled maintenance. The energy recovery that can be expected is in the range of 76% on the production of domestic hot water. It would be even higher when the heat is used for space conditioning. The system has also reduced greenhouse gas emissions by 150 tonnes/year. Gateway Theatre Another notable installation is at the Gateway Theatre in Richmond. B.C. Completed in 2013, the 50,000 square foot public facility is home to Metro Vancouver’s second largest theatre company. The project arose as part of the city’s carbon reduction strategy, which included a SHARC system to reduce the facility’s emissions by 50 tonnes/year. The design was retrofitted to replace an existing incremental heat pump-based HVAC system that was supplied by a boiler and cooling tower and 29 heat pumps. With a fl w of nearly 950 litres/minute of sewage from a city source, 1 million BTU per hour are produced. It is the first wastewater heat recovery system installed in a public facility in Canada.

Spill Response

Kayaks prove a versatile tool in spill cleanup By Cliff Holland and Charles Ross

ightweight and highly maneuverable kayaks are becoming increasingly popular as vehicles to deal with spills of hazardous chemicals and petroleum products. “We’re familiar with kayaks being used for all sorts of recreation,” said Cliff Holland, environmental director of Spill Management Inc. “But we’re still not used to thinking of them as a serious working vessel that can play a big part in averting an environmental tragedy from a chemical spill.” Holland’s firm has provided site-specific and product-specific response training for 25 years to a wide range of clients, including mining and forestry interests, industry and the military, where potential spills to waterways are a major concern, particularly in remote areas. “When we design training programs, one of our focuses is on selecting supplies and equipment that have multiple and diversified applications and are appropriate for the site and potential problems,” said Holland. “When response time is a critical factor, you can’t always count on having everything you would like on hand, particularly when you’re away from urban areas.” As response teams must be able to improvise spill control measures in a variety of weather and terrain conditions and site accessibility, kayaks can be a big help in spill response. Holland is familiar with the challenges of dealing with spills on water. He has used small watercraft and inflatable dinghies for cleanups in boat slips and along shorelines for a number of years. Ten years ago, Holland decided that much smaller craft were a better choice for a variety of spill response training. The composite hulls of Pelican kayaks were compatible with the chemicals they would come in contact with. The low-profile watercraft is stable for trainees and can be easily stored in a hazmat trailer. Spill Management now has three kayaks, for emergency plans and for training. They were recently used in site-specifi

training programs for a mining company in northern Ontario and a pipeline company in the Canadian Rockies. One unit is used for water sampling, reconnaissance, inspecting areas for boom deployment and evaluating changing conditions on the water. A second is used for moving supplies and equipment to various staging areas, as well as spill recovery and shoreline cleanup. The third is a two-person unit that is used to help concentrate spills in calm water and for boom deployment and recovery. The craft can easily be stored in a large trailer and are very light and easy to move so that they can be deployed in minutes. If conditions are too rough to use a kayak, they are too rough to slow, divert, contain and recover oil spill products. Responders may have to move downstream from a spill to find tranquil waters, such as a pond or lake, where large boats may not be a good choice. “At a hydro generation dam in northern Ontario, we had a kayak working with two power boats during a training exercise to recover a spill. The kayak was able to go into shallow water along the shoreline where the power boats couldn’t go,” said Holland. “During the exercise the large powerboat was blown into the spill holding area as it tried to

maneuver in shallow, rocky water. In real life, this could have resulted in the spilled material once again being released.” Spill Management has also used a kayak as a sled to transport supplies and equipment to a spill site. It actually performed better than a sled as the shape of its hull prevented it from digging into the ground and helped to maintain sideto-side stability. Once at the site, the kayak could be used on the water, or it could be used to transport injured personnel back to where they could receive medical assistance. During training at a pipeline company, a kayak was used for secondary containment to catch a transportation spill. While the training spill was only water, it could have been a vehicle fuel tank that was leaking or an oil drum being transported. These lightweight and easily maneuverable kayaks allow responders to quickly deploy booms on a body of water, since they are very maneuverable and unsinkable. The ease of using a kayak means that booms can be quickly placed to contain a spill and make recovery easier. For more information visit: www.spillmanagement.ca

Optimizing dry polymer performance Dry polymer performance starts with effectively wetting each particle. However, metering polymer directly from a feeder into a “wetting bowl” fails to disperse it. The HydraMax pneumatic conveyance system by Velocity Dynamics Inc. thoroughly disperses polymers, prior to wetting, which minimizes hydration time. It does so more effectively than any other blender on the market. Tel: (905) 864-9311 Web: www.proaquasales.com Pro Aqua

New tool allows businesses to factor water risks

ater scarcity is impacting the vitality of communities around the world. For businesses, it is a significant constraint to growth. The Water Risk Monetizer is a financial modeling tool that enables businesses to factor water into decisions that support business growth and help ensure the availability of this limited natural resource for future generations. Insufficient access to clean water can significantly disrupt operations, increase costs and curtail growth. Despite increasing risks to businesses and communities, the cost of water today in many regions of the world remains relatively low. The Water Risk Monetizer helps bridge the gap between market price and risk (based on scarcity) by calculating a risk-adjusted price comprising forecasted future water costs, plus a risk-based premium that represents the value that should be placed on water based on real and future water scarcity risks. This premium makes it easier to factor the potential cost or impact of water risks into business decisions in the same way other risks are considered in planning and capital allocation. Developed by Ecolab Inc., and Trucost, the Monetizer is available at no cost to businesses throughout the world, and the secure site is designed so only the user has access to the inwww.esemag.com

formation entered. It uses a scientifi model to quantify the potential impact of water scarcity on a facility in monetary terms. This model correlates local water scarcity to considerations that contribute to the full value of incoming water, based on scarcity, for a specific facility, including: current and projected water use; current and projected local water scarcity; economic variance and purchasing power; and population and GDP forecast. The tool correlates a facility’s water use to these local water scarcity considerations to calculate a “water risk premium.” When added to the local price a

business pays for water, the water risk premium quantifies the value a business should place on water based on real and future water scarcity risks. The model aligns scarcity data with current market conditions to cap the water risk premium at the highest price paid for water globally today. The result is a financial assessment of water risks, calculated in current and three, five and 10-year projections. Information can be used by businesses to better understand water risks and the potential cost implications of water scarcity for a particular facility. www.waterriskmonetizer.com

Canada makes HFCs a priority at climate summit Recently, Leona Aglukkaq, Minister of the Environment, Minister of the Canadian Northern Economic Development Agency and Minister for the Arctic Council, addressed the 20th Conference of the Parties to the United Nations Framework Convention on Climate Change in Lima, Peru. Aglukkaq spoke about Canada’s commitment to developing an international climate change agreement and the country’s reductions in greenhouse gas emissions. According to the minister, 2012 GHG emissions were 5.1% lower than 2005 levels, while economic growth was 10.6% during the same period. In addition, Canada’s per capita emissions have now fallen to their lowest level since 1990. Aglukkaq has stressed the importance of reducing HFC emissions in figh ing climate change. “By taking action on HFCs, Canada is now among those countries showing leadership by taking early action on these substances, which could account for up to 19% of global GHG emissions by 2050 if no immediate action is taken,” she said.

massive 180 km pipeline-canal mega-project to bring water from the Red Sea could prevent the Dead Sea from disappearing while improving the region’s environmental, energy and peace prospects. This is according to a book of insights into major global topics launched in late October by an association of former government leaders and heads of state and the UN University’s Institute for Water, Environment and Health. Titled “Water, Energy and the Arab Awakening,” the book also covers topics ranging from arms treaties, energy challenges and the risks of sectarianism. For years, Israel, Syria and Jordan have diverted more than 90 per cent of the southward fl w of the River Jordan to agricultural and industrial purposes. This has choked the Dead Sea, the lowest point on earth, causing severe negative consequences on the ecosystem, industry, and wildlife in the area. Due to gradual water loss, the sea has split into two separate lakes and its coastline has receded significantl . The Red-Dead Canal, as envisioned by Jordan, is a 180-kilometre, partially covered pipeline across Wadi Araba - a dry

plateau stretching from the Gulf of Aqaba in the south to the Dead Sea in the north. It would carry around 1.5 billion cubic metres of water per year, pumped first to an altitude of 150 metres above sea level before fl wing down a 580-metre decline. Consisting of Jordan, Israel and Palestine, the three-party project would restore the Dead Sea’s water level over time. It would also generate hydroelectricity for large desalination plants, relieving chronic freshwater shortages while helping to meet energy needs. Former leaders of Canada, Colombia, Cyprus, New Zealand and Singapore contributed to the wide-ranging book launched in the U.K. by the InterAction Council (IAC), a 32-year-old association created to pool the expertise of former world leaders and to speak out on issues of vital importance to the world community and current leaders alike. According to Jean Chrétien, former Prime Minister of Canada and IAC’s cochair, the InterAction Council selects issues and develops proposals for action within these areas and communicates these proposals directly to government leaders and national decision-makers.
