EDITORIAL COMMENT BY STEVE DAVEY

What did the Trump presidency mean for the environment and for Canada?

ack in ES&E’s February 2017 issue, I commented that like it or not, Canadians would have to accept that Donald J. Trump had become the 45th President of the United States. This put many long-standing political issues in flux, including cross-border trade, infrastructure, water, climate change, etc. At the time, based on his proficient use of Twitter, countless speeches and his campaign website, it was fairly clear where the new president stood on key environmental issues. As far back as 2012, Trump tweeted that “the concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive.” Since then, he stated many times in debates and televised briefings that he did not accept that climate change was real. As part of his 2016 campaign, Trump said that clean water may be the “most important issue we face as a nation for the next generation. We must make the investment in our fresh water infrastructure to ensure access to affordable fresh water solutions for everyone.” He said on ScienceDebate.org: “We must explore all options to include making desalinization more affordable and working to build the distribution infrastructure to bring this scarce resource to where it is needed for our citizens and those who produce the food of the world.” “In a Trump administration, there will be shared governance of our public lands and we will empower state and local governments to protect our wildlife and fisheries,” Trump also said on ScienceDebate. “Laws that tilt the scales toward special interests must be modified to balance the needs of society with the preservation of our valuable living resources.” SO WHAT HAPPENED? During the first few days of his term, President Trump issued a Presidential Memorandum to restart the Obamablocked Keystone XL pipeline from Hardisty, Alberta, to Steel City, Nebraska, as part of his plan to expand the oil industry. Prime Minister Justin Trudeau welcomed the President’s move to revive Keystone, saying: “I’ve been on the record for many years supporting it because it leads to economic growth and good jobs for Albertans.” After becoming president, Trump pulled the U.S. out of the Paris Climate Change Agreement that some 200 countries had agreed to in 2016. Its goals are to reverse the worst effects of global warming. Trump was quoted as saying that the U.S. shouldn’t waste “financial resources” on climate change and should instead use them to ensure the world has clean water, and to eliminate diseases like malaria, increase food production, or develop alternative energy sources. The New York Times recently reported that the Trump administration rolled back more than 100 environmental rules 6 | February 2021

concerning air, water, wildlife and toxic chemicals. The bulk of the rollbacks identified by the Times were carried out by the Environmental Protection Agency, and involved C0₂ emissions from power plants and from cars and trucks, and removing protections from more than half the nation’s wetlands. At the same time, the Interior Department worked to open up more land for oil and gas leasing by limiting wildlife protections and weakening environmental requirements for projects.

TURNING BACK THE CLOCK In his first day as President, Joe Biden issued a Presidential Memorandum cancelling the permit for the Keystone XL pipeline. He has also stated that he wants the U.S. to rejoin the Paris Climate Change Agreement. According to the New York Times, the Democrat-controlled House and Senate could help nullify several more Trump-era rules through a law that grants Congress the power to review regulations recently adopted by federal agencies. Last year, the Trump administration introduced the Navigable Waters Protection Rule, which reduced the types of wetlands and waterways under oversight by the Clean Water Act. This controversial policy replaced interpretations by Obama-era officials and earlier administrations. The new approach meant developers no longer needed federal permits for work that affects some types of waterways now excluded from the definition of “waters of the United States,” or WOTUS. According to Bloomberg Law, the Biden administration is expected to ask the courts to put WOTUS litigation on hold, to give the US EPA and the Army Corps of Engineers time to decide if and how to rewrite the Navigable Waters Protection Rule. During his campaign, President Biden said he wants to spend $1.3 trillion on infrastructure over a decade. This includes $50 billion in his first year in office on repairing roads, highways and bridges, and $400 billion over 10 years on a new federal agency to conduct clean energy research and innovation. This program also has a strong “Buy American” policy, so these concerns could mean Canadian companies will face challenges when dealing with the U.S. However, free and fair trade between our two countries, as well as other mutual concerns like water supplies, cross-border air quality, environmental protection, etc., have always been up for debate and negotiation. As I said in February 2017, Canadians can only hope that our leaders feel as passionate about our interests, as U.S. leaders do about theirs. Steve Davey is the editor and publisher of ES&E Magazine.

WATER

Studying algal blooms, light penetration and oxygen levels in a phosphorus-rich lake By Robert Bowen

he trophic state of a lake is defined by several parameters, including total phosphorus (TP). Hypereutrophic lakes have total phosphorus concentrations that range between 96 – 384+ μg/l along with high chlorophyll levels (56 – 155+ μg/l) and low Secchi depths (0.5– <0.25 m). The TP measured at Swan Lake in Victoria, British Columbia, at water depths of 10 cm, 1 m and 2 m ranged between 200 – 300 μg/l from May to July 2020, before it started to decline as it was consumed by algal blooms. Although Swan Lake falls within the range of TP for a hypereutrophic state, its Secchi depth (0.5 – 1 m) and chlorophyll (~50 μg/l) levels fall just short of this classification. Swan Lake and other lakes with high TP are often associated with nutrient loading through human activities, such as agricultural practices or the runoff from other sources like residential fertilizers and septic systems. Conditions within such lakes vary significantly over the course of a year as available nutrients allow for the ramping up of large biomasses, creating algal blooms and strong diurnal cycling of dissolved oxygen (DO). In 2018, an ASL Environmental Sciences Acoustic Zooplankton Fish Profiler (AZFP) was used to continuously detect the volume of backscatter and vertical distribution of the cyanobacteria Aphanizomenon flos-aquae (AFA). This species has the ability to self-regulate its position in the water column by inflating or ballasting elongated gas vacuoles to control buoyancy. Its specialized adaptation is regulated by a threshold of light tolerance, where light is used through photosynthetic processes to produce the energy AFA requires. Species such as AFA optimize their vertical position in a predictable diurnal pattern that is strongly correlated with light penetration. Their role in systems such as Swan Lake provides huge inputs to oxygen lev8 | February 2021

els during bloom phases. The explanatory power of combining DO loggers and the AZFP with its ability to track cyanobacteria volume and vertical position in the water column, along with nutrient testing, gives valuable insight into the dynamics that led up to a 2018 fish kill. Photosynthetic processes require nutrients, dissolved carbon dioxide and light. Light penetration plays an important role in the distribution of DO in the water column. To examine oxygen production and the role of light penetration in detail, a continuing lake monitoring program at Swan Lake was undertaken, and lux loggers were added to measure light penetration. Lux loggers and DO loggers were deployed between July and October 2020, at depths of 50 cm and 100 cm. These depths were selected since Secchi depths for this lake typically ranged from 30 – 120 cm. Loggers were set to record every 20 minutes and weekly site visits included profiling DO, pH, temperature, oxygen reduction potential, phosphorus

(TP and PO4) and nitrogen (N and NO3). In Figure 1, three panels describe the dynamic range of DO, light and nutrients along with precipitation events. The top panel shows the high amplitude diurnal cycling of DO as photosynthetic organisms oscillate between modes that are dominated by oxygen production during daylight hours and oxygen respiration during the absence of light. Data for this curve were taken from the DO logger at the 50 cm depth. Draped over this curve is the weekly YSI handheld DO probe. These weekly data points reveal only a small part of the highly variable DO cycling. In the middle panel, daily minimum and maximum DO concentrations were plotted for comparisons. The amplitude of the oscillations between these extremes of the diurnal cycle (see shaded area of panel 2), indicates to a large degree the level of biological activity within the water column, and the broad ranges between these extremes are indicative of algal blooms. Precipitation is also displayed on this

panel, showing that rain events typically result in the reduction of DO, possibly due to a limiting of light from cloud cover as well as a reduction in water temperature slowing algal metabolic rates. The bottom panel shows the nutrients and the light penetration at the 50 cm depth. Phosphorus concentrations were very high in early July, but rapidly dropped by the end of July. As the phosphorus levels were consumed and neared zero, nitrate concentrations began to elevate. From water samples and drop-down camera video it was noted that the AFA algae were present in July. With the drop in phosphorus in the latter part of July, this species died back completely. Despite this collapse of phosphorus, the species Anabaena succeeded the AFA and became abundant as this species can generate its own nutrients through atmospheric nitrogen fixation. This succession of species may have prevented a hypoxic event by recharging DO levels. continued overleaf…

WATER Swan Lake has not only seen the succession of algae seasonally as lake conditions change but it has also seen the interannual appearance and disappearance of species. In 2019, the species Azolla filiculoides, having been absent for several years, abruptly appeared in the mid-summer months. This species has the ability to biologically double its population in about 2.5 days. By late August of that year, this species began to displace the typically large populations of duck weed. By October 2019, Azolla filiculoides dominated the water surface to the point where it covered the entire lake. (See Figure 2) During the winter of 2019/2020, Azolla filiculoides died back, with only a small population observed in the spring of 2020. By the end of July 2020, it was completely gone from the lake. Just why this species suddenly appeared and then disap- Figure 2. Abrupt appearance of Azolla filiculoides in 2019, shown here in peared is unclear, but it does suggest that a window of optimal bloom November 2019. conditions for this species (nutrients, temperature, pH, etc.) abruptly opened and then closed, creating a dramatic change in the appearance and ecology of the lake. Another feature of interest from the 2020 data set was the effect of smoke on DO levels. Wildfires are becoming increasingly common in the B.C. interior and the U.S. Pacific Northwest. Thick smoke has covered the Victoria area to varying degrees over the last five years of study at this site and this has negatively impacted oxygen production. This climatic influence, occurring in August and/or September, comes at a time when the resilience of the lake is at a seasonal low. In 2017, thick smoke was one of the prominent driving forces that led Figure 3. Wildfire smoke affects DO levels. to a fish kill and a lake-wide state of hypoxia. (See Figure 3) Funding for this water quality monitoring program was provided by Swan Lake Christmas Hill Nature Sanctuary. DO loggers and the AZFP were supplied by ASL Environmental Sciences.

Coordinated response helped quickly restore Fort McMurray’s drinking water

ocated at the confluence of two rivers, the Athabasca and Clearwater Rivers, the Alberta community of Fort McMurray faces the risk of floods every spring when the rivers thaw. This risk was realized in spring 2020, when an ice jam on the Athabasca River caused water levels to rise rapidly, leading to widespread flooding and water damage. At the water treatment plant, flood waters rose high enough to bypass two flow control gates, causing raw river water to enter the drinking water system. In order to protect public health, a boil water order was immediately imple-

The Regional Municipality of Wood Buffalo, which operates the treatment facility, retained Associated Engineering (AE) to help recovery of the water system and coordinate the work necessary to lift the boil water order. The water system recovery plan was based on similar work performed by the

AE’s project team coordinated with Alberta Environment and Parks and Alberta Health Services for their approval of the water system recovery plan before work started. AE was also responsible for executing the plan, providing technical support to the municipal operations staff, overseeing contracted field staff, documenting completed works, and reporting to the regulators. All of this was required to support lifting the boil water order in a staged approach as the work was completed. Starting at the water treatment plant and working outwards across the distribution system, every reservoir needed to be drained, cleaned, disinfected and re-filled with regulatory-compliant water. As the disinfection and cleaning was completed at each reservoir, clean water from it was then used to flush and disinfect each surrounding neighbourhood. Following disinfection, water quality samples were taken at the reservoirs and key locations within the distribution networks. The team submitted sample

results and documentation to the regulators to lift the boil water orders progressively as the works were completed. Project Manager, Jason Vanderzwaag says: “Our technical experts used Fort McMurray’s water distribution system model to demonstrate that a disinfection dose of 6 milligrams per litre free chlorine could be introduced into the water system. That, along with active flushing at the system extremities, meant we could achieve the necessary saturation of disinfection dose across the distribution network. We also used the water model to identify key monitoring hydrants (e.g., critical points in the system that would be the last to receive the disinfection dose) and late-flush hydrants. These are points that needed to be flushed once the rest of the system had reached saturation.” Once the flushing plans had been generated, Vanderzwaag and his team provided technical oversight to the crews executing the work, including municipal operations staff and contracted crews. Due to the long initial flushing period of

between 8 to 12 hours, plus the 16-hour disinfection time, the work was scheduled over continuous days, with crews rotating between day and night shifts. Thanks to the commitment and rapid work of the field crews, the work was completed and all the boil water orders lifted less than 60 days after the initial flood event. This was much faster than the initial estimate of 120 days and was regarded as a significant success by the Regional Municipality of Wood Buffalo. Following the flood and the initial water recovery works, Associated Engineering worked with the operations staff to perform a root-cause analysis, and identify and repair all the failure mechanisms that led to the water contamination. Vanderzwaag says: “Work is ongoing to address these issues, as well as to mitigate future contamination that may result from more frequent and extreme flood events as a result of climate change.” For more information, email: vanderzwaagj@ae.ca

Citizen science may educate public on pharmaceutical water pollution

new report examining pharmaceuticals found in the Great Lakes considers how citizen science initiatives could be developed to educate as well as fill gaps in data. The Pollution Probe report, prepared for Environment and Climate Change Canada, was undertaken to explore the use of citizen science as a tool for engagement and a means of better understanding pharmaceutical pollution. The new report provides guidance on various sampling methods, shipment and storage, as well as chain of custody. As citizen science gains popularity, the federal government has launched a portal to help provide guidance to people interested in learning how to do more with environmental monitoring. This ability to make more of a difference has led Pol-

tions, collect their own data and advocate for the change they wish to see,” the report states. “It allows for those involved to gain a deeper understanding of their natural surroundings, and contributes to building an informed public that can advocate more successfully for the protection of human health and the environment,” the report adds. Pharmaceuticals have been found in all of the Great Lakes, primarily in effluent or surface water downstream from wastewater treatment plants. However, compounds have also been detected in open waters, fish tissues and drinking water treatment plants, the report notes. Surface water concentrations of pharmaceuticals are often correlated with human population density in the drainage area. Antidepressants, painkillers, birth control pills, antibiotics and endocrine disrupting compounds are often found entering the lakes through municipal wastewater, agriculture and fish farms. In terms of wastewater, medication can enter the Great Lakes from systems connected to homes, hospitals and healthcare facilities, landfill leachate and pharmaceutical manufacturers. While wastewater treatment plants remove oxygen demand, suspended solids, nutrients, foreign materials, and microorganisms from the water, the removal rate or breaking down of the various compounds found in pharmaceuticals depends on the physical and chemical properties of each specific drug. Often referred to as crowdsourced citizen science, the practice has become far more accessible in recent years through the advancement of technology, according to Pollution Probe. “Environmental monitoring technologies and tools for sharing information allow citizen scientists to engage in the collection of data in new and innovative ways, and provide improved means for environmental agencies to use the data generated,” the report states. Still, determinations often need to be made early, whether the intention of the citizen science effort is to provide credible information on water quality conditions to governments or academia, or to simply educate the public through opportunities for experiential learning. “Consideration must be given to how those involved as participants will benefit, and to the complexity of the data gathering process and any associated costs,” the report states. Another possible option for finding cost efficiencies is for citizen science groups to partner with, or complement existing monitoring programs. C

Alberta set for interbasin water transfer as communities added to regional pipeline

new bill introduced in the Alberta Legislature proposes to construct one of the province’s longest regional water pipeline connections, to end drinking water quality and reliability issues for two small communities in central Alberta. Bill 42: North Saskatchewan River Basin Water Authorization Act passed its third reading in early November 2020. If finalized, the legislation would authorize an interbasin transfer of about 175,000 m3 of treated municipal drinking water per year from the North Saskatchewan River to serve about 500 residents in Entwistle and Nakamun Park. Both Entwistle and Nakamun Park are located in the Athabasca River basin. Under the Water Act, transferring water from one river basin to another requires a special act of the Legislature. Reeve of Lac Ste. Anne County, Joe Blakeman noted that the project would be benchmarked as the longest water pipeline in Alberta upon completion. “Connecting Nakamun Park and Entwistle to safe, reliable drinking water marks a milestone along a 15-year journey," said Blakeman. From issues with scarcity, to blue-green algae, to expensive treatment processes, or contaminant spills into local lakes from train derailments, many communities in the region have struggled to maintain stable access to quality drinking water. Under the new proposal, drinking water from the North Saskatchewan River would be treated by EPCOR Utilities in Edmonton through a connection to the West Inter-Lakes District (WILD) regional water pipeline in Parkland County. The West Inter-Lake District Water Commission was created in 2008 with a mandate to bring potable water from the capital

Regional officials had considered sourcing drinking water from lakes or groundwater, or even trucking in water, but “strong support from local residents and the business community” arose for connection to a regional waterline. Construction of the regional water pipeline connection is expected to create about 135 temporary jobs in the region.

Canada works to establish a new federal water agency

anada has opened online consultations towards establishing the new Canada Water Agency, a venture to improve and centralize the country’s freshwater management under the direction of a more dedicated governmental authority.

SPILLS MANAGEMENT

TESI offers a railroad track pan model that can support the weight of a loaded tanker truck.

Catching spills before they hit the ground will cut costs By Merrill Bishop

he petro-chemical industry has invested millions of dollars worldwide to pour concrete slab containments at all their tanker truck loading and unloading racks. Likewise, many railroad tank car users have also installed or poured containment structures under or around their loading or unloading spurs. But what isn’t calculated is the cost to clean up, wash down and maintain these “cheap” open containment solutions. There is also an ongoing cost for “tainted” rainwater disposal from each transloading location. A typical concrete slab poured for tanker truck loading or unloading is 18 metres long by 3.5 metres wide. They are not poured as a single slab and there are expansion joints of fibre material between each section. When these sections settle, the expansion joints are intended to retain the liquid holding ability. But do they? Walk around these slab expansion joints on a clear, warm day and poke around in the groove. Are they stiff and do they hug the two adjacent slabs? Or, is there now a lot of open space parallel to the expansion joint? If you were to 20 | February 2021

pour water on the slab joint, does it disappear? If so, where did it drain to? Many people who use tanker truck loading facilities have little understanding of what they’re “standing on”. A 20 or 25 cm thick concrete loading rack slab has at least 30 cm of backfilled gravel immediately under it. This “river gravel” bed is nearly always connected to the backfilled slab’s drainage ditches. This unintended underground of crisscrossed avenues carries away not only groundwater from the area, but also provides an effective avenue for any seepage that “came down the crack” on the concrete slab. While each floor drain may be securely attached to the adjacent slab, the drainage will happen anywhere there is an irregularity between slab sections. Releases of solvents and chemicals “eat away” at these between-slab expansion joints. As such, an annual inspection and recaulking may be a good investment. Some tanker truck loading rack supervisors attempt to minimize the clean-up labour on their loading slabs by manually moving “sawed-off ” oil drums, or other shallow pans to where they think leaks will occur. Unfortunately, this often does

not work as it may not be clear where to position a manual spill pan. Under where the hose connects to the fixed valve manifold? Where the hose is connected to the belly valve of the truck? On the slab, in the area under the top connection dome of the truck? Also, any veteran loading worker knows that a stiff, 75 mm hose with one end stuck in a 23-litre bucket, will likely tip over the bucket, causing a spill on the slab. Finally, moving a heavy open improvised spill container around is difficult and usually results in a release. That’s why Trans Environmental Systems, Inc. (TESI) developed the Spill-Barrow™, which is a two-wheeled manually moved containment that holds approximately 200 litres of liquid. It can be smoothy inserted below a potential release location and removed without risk of splashing over the side. Beneath railway beds there is usually subsurface clay. This natural barrier does not allow vertical seepage, so any water or contaminants that fall on the railroad track above change course and follow the ballast filled ditch under the tracks. This narrow “rock filled” creek may flow for kilometres, until the railroad track crosses over a stream. Then, spilled contaminants are free to flow with gravity and pollute downstream areas. Taking all these drawbacks into consideration, one can only conclude that it would be much better to catch spills before they hit the railway track, or the concrete containment slab. But, how that’s done varies a lot due to the nature of the chemical or other oil products involved. The released chemical may have high viscosity, or it could be heated. Heated releases will quickly solidify on a cold track pan and overflow onto the ties and ballast and solidify there as well. Releases during pressurized unloading may “squirt” away from the “bad connection” by one to two metres. These containments need to be positioned where the most likely releases would happen. This can be where the drainage hose connects to the belly of the tank car valve, immediately below where the dome connection may be located, or directly under where overflow release valves discharge. continued overleaf…

SPILLS MANAGEMENT Tank car leaks or releases do not happen over the wheel truck assembly, only around the middle of the tank car. This means long pans are not needed if railroad workers place the tank car correctly to begin with. The longer or larger an open spill collection pan is, the more rainwater will be collected and subsequently disposed of. A typical open track containment pan can collect some 6,800 to 20,500 litres of water per year, depending on annual rainfall amounts. This can cost $2,600 to $7,800 per year to haul it away for disposal. Closeable lid containment pans can cut haulage costs considerably. Also, they help avoid the problem of blown-in debris, like leaves and plastic bags. Although some cheaper plastic pan makers offer lift off lids, it takes a person on each side of the track to lift off 10 individual molded lid sections for a six metre pan. Since railroads often deliver a tank car to a customer during off-hours, these sectional “plastic” lids have to be

STORMWATER

Scientists link tire preservative in stormwater to massive salmon die-offs

fter years of research, environmental scientists believe they have identified a link between urban stormwater runoff and substantial annual die-offs of coho salmon after heavy autumn storms in the Pacific Northwest. For decades it was a mystery why as many as 90% of salmon would die when migrating through urban streams in an attempt to spawn in the Seattle, Washington, area. This was pushing them to the verge of extinction according to the Governor's Salmon Recovery Office. The answer now appears to be a highly-toxic undocumented substance derived from a common ingredient in rubber tires, thought to be ubiquitous in more than 1.5 billion existing vehicles. It flows into freshwater streams from roadways during precipitation. All water samples during testing contained a specific chemical signature associated with particles shed from vehicle tires in motion, the research showed. Lead scientists, Jenifer McIntyre at Washington State University and University of Washington (Seattle) engineering professor Edward Kolodzie,

made the discovery working alongside federal agencies, utilities and conservation groups. “We had determined [the die-offs] couldn’t be explained by high temperatures, low dissolved oxygen, or any known contaminant such as high zinc levels,” McIntyre said in a December statement about the investigation. “Then we found that urban stormwater runoff could recreate the symptoms and the acute mortality.” As many as 10 of the state's 14 threat-

ened or endangered salmon species are not meeting current recovery goals, and five species are in crisis. The scientists spent long hours isolating and testing molecules from some 2,000 chemicals in the tire-wear particles to identify whether a certain contaminant or combination of contaminants was particularly harmful. They narrowed it down to one named 6PPD-quinone. During testing, 6PPD-quinone killed salmon within five hours of exposure to concentrations as low as 0.8 micrograms per litre, the scientists found. In a statement following the release of the study in the journal Science, the U.S. Tire Manufacturers Association announced that it uses 6PPD because it “helps tires resist degradation and cracking, which is vital for passenger safety.” The association added that it is “committed to collaborating with researchers at the University of Washington and other scientists to better understand this product, fill knowledge gaps and determine next steps.” Tire manufacturers recommended adding 6PPD to the Priority Products Work Plan for further evaluation.

Challenging wastewater lagoon cleanout for a remote Yukon community By Blair Benn

ld Crow is a small Indigenous community located north of the Arctic Circle in Yukon Territory. It has a population of approximately 300 people, known as the Vuntut Gwitchin. In 2019, Lambourne Environmental Ltd. was subcontracted by Wildstone Construction and Engineering Ltd. to de-sludge and remove floating vegetation from the community's wastewater lagoon. There are no surface roads to the community, so all equipment needed to be flown in on one of Summit Air’s ATR 72 aircraft. This provided a challenge as most dredges are too large to be transported by air. The dredge also had to be capable of removing the floating vegetation material. Lambourne’s Operations Manager, James Dyrland created the final design of the proposed dredge, and a local boat manufacturer created the CAD drawings and built the pontoons. The remainder of the lightweight dredge was built and assembled in-house at Lambourne Environmental. The intent was to dewater the sludge removed from the lagoon using Geotubes, which would work very well for dewatering in such a remote location. A small polymer unit was used, and all the equipment, polymer, laydown area liner and other required materials were transported to site on one planeload in mid-September 2019. The Geotube laydown area was built along one berm of the lagoon, and an RPE liner was installed to control filtrate flow from the tubes and return it to the lagoon by gravity. Once the site was set up, the crew began pumping the sludge into two 13.6 metre circumference x 130 metre long Geotubes. Cold weather forced the shut down of the project in early October as the lagoon began to freeze up. With 2020 and the COVID-19 pandemic, the crew did not return to site 24 | February 2021

The equipment was brought out of storage and went to work removing the floating islands of vegetation that covered a good portion of the lagoon. After four days of vegetation removal, the crew switched back to dredging the biosolids in the lagoon. The project was successfully com-

pleted in early August 2020, having removed approximately 170 dry tonnes of sludge. When the material in the Geotubes has sufficiently dried, it will be removed and used as cover material on site and at the landfill. Blair Benn is with Lambourne Environmental Ltd. Email: blair@lambourne.ca

Project delivery in the Arctic hasn’t changed much since the Klondike Gold Rush era By Ken Johnson

ore than a century after what many consider to be the greatest “event” in the history of the Arctic, the Klondike Gold Rush, it is interesting to compare the delivery of projects during that era to today. A Gold Rush era project of particular significance was the Yukon Ditch. It was a $3 million (1909 dollars), 115-kilometre, flume, ditch and pipeline project designed to deliver 5,000 miner’s inches of water (3,500 litres per second) for hydraulic mining in the Dawson City area. The following excerpts from a site visit in 1909 by an engineer indicate the challenges with project delivery at the time: “The magnitude of the work accomplished by the engineers of the Yukon Gold Company may be inferred from an enumeration of the tasks completed during the three seasons since the first surveys were finished. These include a power-plant of 2,000 HP, with 35 miles of main (power) line, 18 miles of branch, and 8 miles of secondary lines; 64 miles of main ditch, flume, and pipe. “All this has been done 3,500 miles distant from manufacturing centres, with an inadequate supply of labour. Some of the machinery that arrived had been ordered 18 months previously. “During the season of 1907, over 7,000 tons of material was received, and it was inevitable that some of the parts ordered in advance, for immediate operations, should be delayed in delivery despite every effort. A sufficient stock of parts is carried, so as to obviate delays from slowness of transport. “Maintenance of a proper commissariat for labourers required some generalship. An effort was made to overcome the uncertain supply of local labour by importing 320 men from British Columbia. Of these, 20 deserted on the way.” Dawson City, and in fact much of the Arctic remains a project delivery challenge. This was recognized by Arctic engi26 | February 2021

neers in the 1980s, and led to the development of a five-year project delivery cycle. The first year of the project delivery cycle is utilized for project planning. This is a necessary, but often time-consuming and expensive step to establish the required lines of communication between the various stakeholders in the project, and to refine the project needs, and the project resources. Time and expenses are due to the isolation of a project site, and the time needed to invest in understanding the cultural differences and needs of the end user. A simple visit to a project site may take a day or two of travel each way and cost thousands of dollars in airfare. The consultation with the end user is an essential part of the first year because neglecting this segment of the work may delay the project delivery, and lessen the overall success of the project. The second year of a project schedule is utilized for preliminary engineer-

ing and detailed design. These technical stages of the project may be characterized by the various technical activities with typical “southern” engineering such as geotechnical engineering, topographical surveys and background studies in advance of the design. However, these activities require special consideration of the inherent conditions of the Arctic such as permafrost. The design criteria that emerge from preliminary engineering include: careful consideration of cold temperatures, ice and snow, and how these are influenced by wind, darkness and isolation. For example, the efficiency of outdoor winter construction in the Arctic may be reduced by 50%, due to the cold, and another 50% due to the darkness. In total, this means that winter construction may advance at about 25% of the summer working efficiency. The third and potentially fourth year continued overleaf…

This is creating large broken ice fields that can be a hazard to sealift navigation. Other projects, particularly in the western Arctic, may have access to all-weather roads, or winter roads for material and equipment delivery. This allows for delivery during the winter months and for construction to begin as soon as temperatures permit.

Climbing GHGs may stop many lakes from freezing, say York researchers

ew research by Ontario’s York University suggests that if the planet’s greenhouse gas emissions aren’t drastically reduced, 179 lakes could permanently lose ice cover within the decade, then skyrocket to 5,700 iceless lakes by the end of the century. The ice loss could even include portions of the Great Lakes, states the study, published in the journal Geophysical Research Letters. Large bays in Lake Superior and Lake Michigan, for instance, could be ice-free by 2055 if nothing is done to curb global emissions. Ice is needed to curtail and minimize evaporation rates in the winter,

“In years where there isn’t ice cover or when the ice melts earlier, there have been observations that water temperatures are warmer in the summer, there are increased rates of primary production, plant growth, as well as an increased presence of algal blooms, some of which may be toxic,” Sharma explained. Researchers say that increased greenhouse gas emissions will lead to warmer winter temperatures that will even surpass increases in summer temperatures. Just a couple of degrees warmer will make the difference as far as the lakes gradually not getting cold enough in the winter for them to freeze. The York team looked at 51,000 lakes in the Northern Hemisphere through the HydroLAKES dataset to forecast whether those lakes would become icefree, using annual winter temperature projections from 2020 to 2098 with 12 climate change scenarios. They found that when air temperature was above –0.9°C, most lakes no longer froze. For shallow lakes, the air temperature could be zero or a bit higher. Larger and deeper lakes need colder temperatures to freeze, some as cold as –4.8°C, than shallow lakes, the research states. “It’s pretty shocking to imagine a lake that would normally freeze no longer doing so,” said York postdoctoral researcher Alessandro Filazzola in a statement about the new paper.

In the new study, researchers sequence RNA extracted from wastewater samples, but there may be many different strains present because there are many individuals contributing to the sample. This makes it challenging to distinguish the SARS-CoV-2 genetic signal from the billions of bacteria and viruses people excrete every day. “The way that we need to process the sequence information is complex,” explained the January study’s lead author, Dr. Kara Nelson, professor of civil and environmental engineering at the University of California-Berkeley, in a statement. “One contribution of this paper is the ability to prepare samples for sequencing from wastewater. Instead of directly sequencing everything present, we used an enrichment approach where you first try to enrich the RNA that you are interested in,” added Dr. Nelson. “Then we 32 | February 2021

developed a novel bioinformatic analysis approach which was sensitive enough to detect a single nucleotide difference. You can’t get any more sensitive than that.” The study’s researchers developed a novel method to sequence RNA directly from sewage collected by municipal utility districts in the San Francisco Bay Area to generate complete and partial SARS-CoV-2 genomes. Twenty-fourhour one-litre composite samples were collected at four different wastewater interceptors in the area. “Of everyone who gets tested, only a fraction of those samples even get sequenced. When you are sampling the wastewater, you get a more comprehensive and less biased data on your population,” explained Dr. Nelson. “It appears that we might be able to get an earlier signal in the wastewater if a new variant shows up compared to only relying on the sequencing of clinical samples.” By understanding which strains of SARS-CoV-2 are present in populations over time, researchers can gain insight into how transmission is occur-

OTTAWA CLOSING IN ON VARIANT Wastewater continues to be a useful marker for tracking COVID-19 in the nation’s capital, where viral loads have plateaued since the start of the new year. But Ottawa, Ontario area researchers are still finalizing a way to adapt testing for the B.1.1.7 U.K. variant of COVID-19. That ability would give researchers a potential two-week head start to react to community infection levels prior to people eventually testing positive in a clinical setting. New information from the collaboration between the CHEO Research Institute and University of Ottawa researchers with Ottawa Public Health suggests that wastewater testing for the variant, which first surfaced in the U.K. and is widely considered to be more contagious, may still be a few weeks out. As of January 30, Ontario had confirmed 57 cases of the U.K. variant in clinical sequencing, with infections reported in new regions, including Halton and Waterloo. Ottawa is one of the only cities in Canada doing daily wastewater testing for the virus SARS-CoV-2 thanks to the fact that the Robert O. Pickard Environmental Centre collects and treats wastewater from 91.6% of the city’s population. Elsewhere in Ontario, Thunder Bay has just started its own wastewater testing for the virus. In the Northwest Territories, the latest testing from Hay River shows zero levels of viral load in the community’s sewage.

Innovative filter greatly reduces discharge of microplastics in wastewater effluent

ven though the breadth of the problem may be hard to grasp, studies have shown that microplastics represent a danger to humankind and the environment. However, state-of-the-art wastewater treatment plants equipped with the relevant filter technology are already able to filter out microplastics from wastewater, thereby drastically reducing their release into the environment. Based on the current definition, microplastic particles are smaller than 5 mm. They are broken down into two groups. Primary microplastics are a component found in numerous products such as cosmetics and personal care products, as well as in cleaning products. Secondary microplastics are produced by physical, biological and chemical degradation processes from large plastic parts, i.e., granulated plastic bottles. Microplastics can be released into the environment either directly or indirectly. They can be released through water bodies and by land (wind, rain). Just like paper, plastic fibres and particles from clothing and cosmetics are flushed into all types of water through household drains, sewers and wastewater treatment plants (WWTP). Our knowledge about the amounts released into the environment and the potential retention is, as of yet, still limited. The German Federal Ministry of Education and Research dedicated the research project “Removal of Microplastics from the Water Cycle (OEMP)” to precisely these questions. As part of this research, the INVENT iFILT -Diamond Filter was tested for the removal of microplastics fromWWTP discharge and mixed water overflows. The filter is based on a revolutionary fluid mechanics general concept. The basic idea is to combine an optimized fluid mechanics design with the cross-flow filtration process engineering approach. This allows a high hydraulic performance to be achieved despite minimum

space requirements, yet with an optimum separation efficiency. The continuous rotation of the filter wheels, the effect of tangential-dynamic filtration that it initiates, and the sharp separation limit of the stainless-steel high-performance weave mesh utilized, provide for high separation efficiency. During the course of the research project, GKD-Gebr. Kufferath developed a novel stainless-steel high-performance weave mesh, which was then tested using the INVENT iFILT -Diamond Filter. The weave mesh that was developed features extremely small opening widths of 6 and 8 µm. They are the absolute pore size that guarantees no spherical particles any larger than the opening widths can make their way through the discharge of the filter. The filter media primarily used up until now have featured an absolute separation limit in the range of 15 μm. The slot-like pore geometry of the weave mesh ensures excellent retention of particles. Openings in the mesh are larger than on the mesh surface, ensuring good regenerability. Tests of the WWTP discharge were

carried out at a large Berlin WWTP. Daily treatment performance was 247,500 m3, which increased to up to 600,000 m3 during rainy weather. The biological treatment method included an activated sludge process with denitrification and biological phosphorus elimination. In order to create valid comparison values, the Diamond Filter was first equipped with a standard 20 μm weave mesh. This step already reduced the dirt load of filterable substances (AFS) from 5 mg/l in the inflow to below 3 mg/l in the discharge. After retrofitting to the new weave mesh with a separation limit of 6 μm, the discharge concentration was then further reduced from 3 to 2 mg/l. In addition to increasing the separation performance, due to the novel weave mesh and the Diamond Filter concept, yet an even higher throughput capacity was achieved. With a filter wheel, throughput rates of 110 m3/h could still be achieved when using the 6 μm mesh. In relation to the installed filter area, this equates to a specific hydraulic capacity of 22 m3/(m2xh), which is an absolute peak value in the field of gravity filtration.

Environmental Science & Engineering Magazine

Measurements for microplastics showed that the total plastic masses were subject to considerable fluctuations even within one day. It was not possible to determine any system in the values. While traces of plastic were found in the WWTP discharge, they were hardly detectable in the discharge of the Diamond Filter. Tests confirmed that significant traces of plastic even in the lower μm range were removed from the water. For the mixed water treatment tests, the filter was set up in the mixed water overflow basin. Concentrations of filterable substances are significantly higher here as compared to the WWTP discharge. Even for mixed water, the iFILT -Diamond Filter with the 6 μm weave mesh was able to achieve a separation performance of filterable substances in excess of 99%. These results are extremely promising. By using the tertiary Diamond Filter in WWTPs and thereby almost completely removing microplastics, adverse consequences to the environment and humankind can be reduced.

INSTRUMENTATION

How three municipalities are changing the game with level measurement technology By Greg Tischler

ew level measurement technology is increasing the safety and simplicity of widely-used processes found in every wastewater treatment plant (WWTP). Radar sensor technology is making waves across the industry, proving to be more accurate and more reliable. WWTPs have traditionally relied on ultrasonic transmitters, bubblers and floats. Each of these technologies were once considered cutting-edge, but in today’s world of doing more with less, they can require a lot of maintenance to keep them working properly. As radar technology has become more prolific, it has also become more affordable and cost-effective for WWTPs of any size.

LIFT STATIONS One municipality relies on 160 lift stations to move wastewater to four treatment plants. These lift stations are scattered across a large collection system, and every one of them uses sensors for level measurement and pump control. One particularly shallow well was using an ultrasonic transmitter in combination with a submersible pressure sensor. With the current setup, pumps were short cycling, running for roughly two seconds per cycle, which caused inefficiencies and put unnecessary wear and tear on the pumps. To remedy the situation, operators tried a new VEGA radar sensor, the VEGAPULS 31, paired with a VEGAMET 861 controller. VEGAPULS 31 is an 80 GHz radar sensor for non-contact continuous level measurement. The radar’s higher frequency means the sensor has a much narrower beam angle, allowing it to only measure the surface of the water and avoid other obstructions in the well. The higher frequency also allows the radar to measure through the light foam often found in lift stations. Specialized electronics inside the housing ensure 36 | February 2021

Thanks to the new radar sensor and its more reliable, consistent measurement, operators have a better idea of how much water is entering the plant. A REVOLUTION IN PROGRESS No two collections systems, water treatment, or WWTPs are identical, but many of them use similar processes requiring similar measurements. Operators need reliable measurements to keep pumps running smoothly, maintain inventory of important chemicals and additives, and measure how much water is moving through their facility. VEGA’s newest generation of VEGAPULS radar level sensors provides the reliability and accuracy operators need. Each new radar is easily set up and configured using a secure Bluetooth connection with a laptop, smartphone, or

How climate change is affecting the consulting engineering sector By Pat Coleman

hree years ago, I was listening to my family talk about climate change. I realized that I knew a lot about climate change, but only in a very narrow area, which was greenhouse gas emissions from wastewater treatment plants. However, listening to the anger, the concern and the fear expressed by those in the room, I knew I had to learn more. To increase my understanding of climate change, I enrolled in the University of Waterloo’s Graduate Diploma in Climate Risk Management program. The four courses I took are: • Climate change fundamentals; • Climate analytics; • Carbon accounting and management; • Business and climate change. The curriculum of the business and climate change course explored the answers to three key questions. Firstly, why must business face up to the reality of climate change? Everyone on this planet is at risk from climate change. Developing countries in the southern hemisphere and young people shoulder most of the climate change impacts, although they did not create the problem. Our businesses, with supply chains that cross the globe, are at risk. Therefore, our companies are part of the problem but can choose to be part of the solution. In other words, we, as employees, decide how our companies will contribute. Secondly, how does business face up to climate change? Our economy must shift away from fossil fuels if we are to avoid chaos. Governments will act, hopefully, for the good of all Earth’s inhabitants. The government and other stakeholders will drag companies out of their silos to face a warming planet's challenges. Smart businesses will not wait for this, they will be proactive and partner with governments and others to shift the economy. Finally, what must business do to 38 | February 2021

address climate change? Companies must set goals, measure, and act. Companies rely on lenders and insurance providers. If these two sectors fail to respond, the financial system may not weather the disruption ahead. Investors must walk away from projects that damage the environment and shift their attention to plans that change the economy. If the business sector remains in their silo, we are in danger of an economic collapse. Humans changed the planet to suit us at the expense of other species and, ultimately, ourselves. We mined stored carbon from the Earth over a short period to feed our insatiable appetite for energy. The carbon dioxide released became trapped in the atmosphere and dissolved in the oceans. Our climate started to change. It is no longer “business as usual”. Our actions, our laws and policies, and our business activities changed the planet. The same actions, policies and activities can undo the damage and restore the Earth. If we suffer, so will our companies. We must adapt to, and mitigate, climate change impacts on our companies, communities and families.

Businesses make a deadly mistake when they choose to be myopic, thus limiting their planning horizon to political and financial cycles. The global business environment is not stable. Business leaders must lift their eyes from their desks and look at their supply chains and their customers. Responsible companies reduce their impact and engage their supply chains and customers in the process. Climate change impacts undermine the most important principle of business, which is stability. Extreme weather events, average temperature increases, sea-level rise, expanded desertification and diversity loss threaten business. Finance, staffing and supply chains are vulnerable to these physical impacts of climate change. The most complex finance planning tools fail when the past is no longer a reliable predictor of the future. The best business plan becomes a work of fiction if a government passes a new law, the public turns against your brand, or a new technology disrupts your business model.

REINVENTING THE CHEMICAL DOSING SYSTEM The DICE Dosing Module, by Meunier Technologies, integrates all the necessary discharge components required for a typical chemical dosing system. The block type design allows for a rigid, compact and reliable product, and the significantly reduced number of connections greatly decreases leakage potential. The module allows for better precision and protection in the dosing system, and also features great quality due to its machined fabrication. The Dosing Module overcomes the many fundamental problems of the current piping system design: • Poor quality of the piping connections; • Many potential leakage points; and • Excessive vibration caused by the pump pulsation – which leads to mechanical fatigue on connections and components. Other features include: • Integrated: ° Ball valves for outlet, calibration column, and drainage; ° Auxiliary ports: pulsation dampener, washing port, transport/dilution water and secondary pumps; ° Adjustable back pressure valve; ° Adjustable pressure relief valve; ° Pressure gauge with isolator; and ° Standard design that fits all your essential needs. • Extensive reliability and durability; • No threaded or glued connections; • Extremely compact design resulting in minimal footprint; • With only 3 supporting bolts and 4 connections, the module can easily be installed on new and existing systems (retrofit); • Possibility of having only 1 Dosing module for 3 pumps (1 injection point, 3 pumps); and • Capability of calibrating the pump with the correct suction head and discharge pressure.

Industry partnerships created indices to track a company’s risk and efforts to adapt or mitigate these risks. The Global Reporting Initiative, CDP, and others, provide these indices. Consistent reporting increases transparency and accountability. Chaos brings opportunity because the established players lose their hold on the market when they do not adapt. Agile companies shift their assets, operations, or products to capture a more significant portion of the market, while laggard companies flounder. Unless the polluter pays, the economy does not shift. Environmental regulations moved the economy away from smog-producing emissions and habitat destroying practices. The government, in these cases, intervened for the good of us all. They will have to again by placing a price on carbon emissions. Governments can choose to cap emissions and let the market set the carbon price (cap-and-trade). The other alternative is for the government to tax carbon and then wait to see how the economy responds (carbon tax). Other mechanisms, such as providing subsidies, imposing regulations or new efficiency standards, and encouraging public pressure cannot, on their own, provide the magnitude of the shift required to hold the temperature rise to less than 2°C. A change will only occur when the polluter pays relative to damage their emissions are causing to the planet. Figure 1 lists Stantec’s sustainability scores.

Study identifies wastewater management strategy for western Saskatchewan

he Rural Municipality of Frenchman Butte No. 501, located in western Saskatchewan, covers over 1,900 square kilometres and encompasses several communities within its boundaries. These include the Town of St. Walburg, Village of Paradise Hill, Onion Lake Cree Nation Reserve, the Fort Pitt Farms Christian Community, and the Hamlet of Frenchman Butte. Historically, household wastewater was discharged to residential holding tanks, septic tanks, or lagoons. Periodically, wastewater from holding and septic tanks was pumped out and transported by haulers to various sites for land application. Recently, the Saskatchewan Ministry of Environment indicated its intent to terminate land application of wastewater in the next five years. Taking a proactive approach to the pending regulatory change, the Rural Municipality decided to conduct a wastewater management study to investigate its options for wastewater treatment. They wanted to identify the most feasible way(s) to manage wastewater for the entire area. They also wished to determine if they could meet the needs of several communities, without requiring each community to provide all of the wastewater treatment infrastructure. Lastly, the Rural Municipality also wanted to explore any options available to provide partnerships within their boundaries. Associated Engineering’s initial assignment included an assessment of the area’s wastewater treatment and disposal needs, and identification of opportunities for developing a regional wastewater treatment facility. Based on the recommendations in the wastewater management study, the Rural Municipality retained Associated Engineering to proceed with the detailed design and construction of a wastewater management system.

Stripping ammonia from landfill leachate to produce hydrogen makes economic sense By Dr. Robert Eden

eachate production is the scourge within every landfill manager’s range of responsibilities. With careful planning and engineering, a landfill team can contain and control it, but it never goes away. Many years ago, there was a similar problem with landfill gas. In one infamous case in the United Kingdom, recognition that a covered landfill site produced substantial quantities of gas occurred when a property near to a newly clay-capped landfill, in the town of Loscoe in Derbyshire, exploded. A domestic heating boiler ignited in the early morning of March 24, 1986, in a property some 150 metres from the landfill. The whole house exploded. The authorities investigating the explosion first looked for a natural gas pipeline leak. It was only after concluding that there were no such leaks anywhere to be found that eyes turned to the landfill. Gradually, the awful truth dawned on city engineers that their landfill, recently covered to prevent problems with rats, birds and flies, was now the producer of gases with the potential to blow up any of the homes around the landfill. The quantities of methane being produced were largely unknown. Gas production estimation is now an established art, verging on being a science, but at that time there was little reasonable basis for even guesswork. The first pioneers in the subject, such as Marion Carter and Associates who were charged with rendering the site safe, worked at the frontiers of knowledge. In the U.K., for example, when London Brick Landfill decided to collect the gas from their site, the discussion held was whether to use 12 or 20 mm pipe. Gradually, pipe sizes increased until they finally reached 250 mm in diameter. By this time, the motto for landfill gas had become: “Turn a liability into an asset.” 42 | February 2021

The WENT landfill site in Hong Kong, showing current ammonia removal facilities.

Could the same be true for leachate? Is it possible to turn this liability into an asset? Many minds have been exercised with this challenge but so far no one has broken through. Leachate remains a potentially troublesome problem with no clear route to becoming an asset. AMMONIA REMOVAL FROM LEACHATE In Hong Kong in 1997, Organics Group constructed the first large-scale thermal ammonia stripper to treat landfill leachate. The WENT facility was rated at 1,800 m3 per day with a design influent ammonium ion concentration of 6,700 mg/l and a discharge requirement of 100 mg/l.That is equivalent to a daily removal rate of 12 tonnes of ammonia. This situation was unique. There was a high ammonia concentration, a severe shortage of land and a great deal of waste heat available in the form of landfill gas, ready for use. Given the high ammonia, the cost of carbon source to run an anoxic reactor ran into millions of dollars a year. The instruction with this first unit was to use as much landfill gas as possible, as Swire BFI, the then owner, would oth-

erwise simply flare it. Organics Group designed the unit with a landfill gas flow rate of 6,000 m3 per hour. At the time, the concept of recovering ammonia to produce hydrogen was not thought of. The objective was to remove ammonia as rapidly and cheaply as possible and to destroy it. AMMONIA’S PROPERTIES Ammonia is a good source for hydrogen, as well as being an ideal hydrogen carrier. It is a counter-intuitive fact that although ammonia only contains 17.6% hydrogen, for a given volume of practical storage, it holds more hydrogen than pure hydrogen itself. Hydrogen is a liquid at −252.9°C. It is usually stored as a liquid or as a gas compressed to 700 bar. Ammonia by contrast, is a liquid at either 7.5 bar (at 20°C) or −33.3°C. Two forms of ammonia are encountered in wastewater: the ionic form (NH4+) and the gaseous form (NH3). The relationship between ammonia gas and the ammonium ion is: NH4+ + OH– ←—→ NH3 + H₂O Dissociated ammonium (NH4+) is converted to undissociated, or free, ammonia gas (NH3) by the addition of a base, such

WASTEWATER as sodium hydroxide. As the temperature of the water increases, the amount of free ammonia gas also increases. The balance of this equation is a function of pH and temperature: low pH and low temperature push the balance toward NH4+. The ratio of ammonia in the gas phase to the total ammoniacal nitrogen, referred to as “f ”, may be expressed as: f = NH3 / (NH3 + NH4+) The relationship between pH, temperature, and “f ” takes the general form depicted in Figure 1. As the temperature increases, denoted by the direction of the arrow, the necessary pH to maintain a value of “f ” decreases. Ammonia is currently the second most commonly produced chemical in the world (after sulfuric acid), with around 200 million metric tons produced in 2019. Nearly 85% of it is used for fertilizers. Although nitrogen comprises almost 80% of the Earth’s atmosphere, because it is inert, it is chemically and biologically unavailable for use in this form. Therefore, ammonia is used in fertilizers to provide the nitrogen source required to increase crop yields. Ammonia and ammonia byproducts have a multitude of applications. For example, ammonia is often employed as a refrigerant in cooling systems. Compression converts it into a liquid with relative ease. When converted back into a gas, it absorbs heat, hence its use in

refrigeration engineering. The textile industry uses ammonia in the dyeing of wool, cotton and silk, as well as in the production of nylon. Household floor cleaners and detergents commonly use ammonia. Chemical process industry facilities use ammonia for pH control and to manage NOx. NOx, when combined with ammonia under the correct conditions, produces nitrogen and water. Ammonia is also an important ingredient in fermentation processes as it serves as a source of nitrogen to encourage microorganism growth and adjust the pH. LEACHATE AMMONIA TO HYDROGEN The route from leachate to hydrogen

involves stripping the ammonia from leachate, distilling the ammonia to produce anhydrous ammonia, then cracking the ammonia to produce hydrogen and nitrogen. Ammonia removal, in this case, can utilize either landfill gas, biogas or waste heat from gas engines.

WASTEWATER duced using renewable energy. “Emerald” ammonia is ammonia recovered from otherwise polluted waste streams. Distillation and drying of ammonia gas to produce anhydrous ammonia is a straightforward chemical engineering exercise. Ammonia decomposition, or “cracking”, has long been used in industry to generate forming gas (3H2 + N2) With interest now shifting to the generation of high purity H2 (>99.99%) for fuel cell vehicles, the ammonia cracking and hydrogen separation technologies require specific attention, as traces of NH3 will irreversibly damage the membrane in polymer electrolyte membrane fuel cells. This level of purification must be achieved either by near-complete conversion of NH3 or through post-cracking purification. Ammonia cracking is, therefore, an area of ongoing research and development, with improvements both achieved and anticipated. Hydrogen management and use is a very well-established field of engineering expertise. At which point in the ben-

This quantity represents 2.5 tonnes per day of hydrogen. However, cracking ammonia is an endothermic reaction which takes place in low pressure and at around 500°C. There are several key alternative designs of a cracker. THE ECONOMICS Current conversion efficiency is in the region of 75%, giving approximately 1.9 tonnes per day of hydrogen. The pump price for hydrogen is in the region of $14 to $20 per kilogram, making the 1.9 tonnes worth $26,000 to $39,300 per day at the pump. Clearly, this will be discounted for wholesale rates, but the residual value will remain of interest to those who seek value from leachate. With the cost for disposal of ammonia-leachate running into hundreds, if not thousands, of dollars per tonne of ammonia, the possibility of converting this particular liability into an asset is one that would be welcomed by leachate management and disposal players, as it would signify a considerable reduction in operating costs.

St. Jacobs WWTP installs prefabricated modular insulated floating tank cover system

he St. Jacobs Water Pollution Plant was built in 1971 to process commercial and residential wastewater. As a result of increased demands on the 430 m3/day facility, upgrades were necessary for it to run as efficiently as possible with minimal downtime. During winter, the aeration rollers within the oxidization tank would occasionally freeze up. This would force facility operators to shut down the tank and manually clear the ice from the rollers, resulting in considerable loss of productivity within the tank. Layfield was contacted by the Ontario Clean Water Agency, who is contracted to run the plant, about installing an insulated floating cover to minimize heat loss from above the tank and thus prevent roller freeze-up. Layfield proposed that a prefabricated REVOC modular insulated floating cover (MIC) system be installed in the tank. This would reduce heat loss within the tank and provide a more consistent, predictable environment for the bacteria. The insulated cover consisted of 22 prefabricated MIC panels, in rectangle and pie shape configurations, that would provide an R16 layer of insulation over the tank. Each panel was fabricated at Layfield’s facility with 100 mm-thick closed-cell foam encapsulated with an EL6060HD Enviro Liner geomembrane.

INSTALLATION The prefabricated modular approach made installation very efficient. It took only about three days to install the panels, while the plant was kept in operation during the installation of the cover. Each of the lightweight panels was floated onto the tank. They were then secured to the concrete tank’s wall, using stainless steel eye bolts and lacing wire to prevent panel shift and wind uplift.

all freshwater withdrawals. That's a lot of water and a key reason why innovators are working to launch new technologies designed to treat and clean industrial wastewater. This means freshwater resources can be preserved for potable water, farming, etc. By using some of the latest cleantech solutions, industrial wastewater can be recycled, so a variety of manufacturing plants, mining companies, and oil and gas producers no longer have to withdraw millions of litres of freshwater daily. Canada uses about 80% of its freshwater withdrawals for industrial purposes, which amounts to 33 billion m3 per year. The U.S. is the largest user of industrial water, withdrawing over 300 billion m3 per year. This is nearly half of all freshwater withdrawals in the country every year. America’s rate is over double that of China, the second largest, which uses around 140 billion m3 per year. Industry is currently incentivized to focus only on what is required (regulations) and what makes the most money (to increase shareholder value). Non-regulatory/financial incentives are an entirely separate dispatch, so let's assume the following becomes a requirement. One seemingly simple idea that is now gaining traction is to incentivize, and then in the future force industry to create closed water loops. Sometimes referred to as zero liquid discharge (although that term is inaccurate) closed industrial water loops limit freshwater withdrawals via recycling, treating, reuse and strict conservation measures. Like crowdsourcing, reduction of freshwater withdrawals by industry requires lots of people contributing a seemingly modest amount of effort to have a large impact. Recycling does not necessarily involve treatment. Effluent dilution, or just reclaiming wastewater as-is for another purpose, is “recycling.” Reuse is just that, using a body of water multiple times for the same operation. Conservation is more complicated. Water is seen as a ubiquitous, inexpensive commodity, so the value of creating conservation measures at the plant must have more than a financial impact. Treating industrial wastewater is difficult, because of the unique constituents and contaminants it contains, and the varying volumes. Municipal water and sewage treatment methods often don’t work well when it comes to industrial wastewater. Large construction and service firms have traditionally been retained to build industrial wastewater systems and often they won’t adopt newer technologies and processes. The reason these traditional companies fail is that they bring to bear traditional water treatment technologies. These involve lots of land, chemicals, additives and old-fashioned methods. In fact, some bid their plant cost based on how much concrete they can pour, and how many of their people they can sell to operate the plant. A “closed” system generally refers to a physical system that doesn't exchange matter with its surroundings. While not strictly adherent to that definition, industrial closed water systems can minimize, and in some cases, eliminate the need for industry to rely on freshwater withdrawals. Closed-loop water systems require an analytical approach. This means determining what quantity of water requires treatwww.esemag.com @ESEMAG

ment, what contaminants are present and what will the treated water be used for. What quantity (daily or monthly) reveals is what size of treatment system needs to be procured. Contaminants dictate what processes are necessary for effectively treating the water. What the treated water will be used for indicates the standards to which the plant will be held. Industrial wastewater requires specialized treatment methods, all working together in a “treatment train.” A typical modern industrial wastewater treatment train will treat for individualized contaminant classes in a stepwise fashion. For instance, treating wastewater at a coal coking plant would involve suspended solids, sulfur chemicals, metals and metalloids, dissolved hydrocarbons, VOCs and salts. Each step should be designed to optimize treatment of a specific contaminant class. Investing in smart water technologies can be a win-win for everyone. These technologies ensure the future supply of water remains intact, and that there is going to be great demand, growth, and profits in this sector in the coming years.

London protects its critical watermain network with pipe condition assessment By Jay Shah

any water asset managers are adopting a pyramid approach to pipe condition assessment. On a selected group of assets, the concept uses cost-effective methods to collect information where possible, and progress to high-resolution and highcost inspection options where needed. This approach formed the structure of the City of London, Ontario’s project plan for its Elgin large diameter pipeline. Following the successful inspection of the 25 km of steel and prestressed concrete cylinder pipe (PCCP) transmission mains, the city was able to confirm that the watermains were in good to excellent condition and that they did not require any short or medium-term capital renewal projects. This allowed allocation of its limited budget towards watermains that had a greater level of degradation and need for renewal. Home to more than 380,000 residents, London recognized the need for a proactive approach toward maintaining a healthy water network as it continues to develop, as well as the necessary increase in transportation projects. Many of these projects were taking place along the Elgin pipeline corridor, an important large diameter watermain network that provides approximately 25% of the city’s water from Lake Erie. Taylor Eckert, project engineer for the city said: “We had some major projects, including a road widening and pipe life cycle replacement. By getting ahead of these projects with inspection and understanding pipe’s condition, it gave us the opportunity to piggyback on the larger transportation projects and save on replacement investment.” The assumption was that the pipeline was in good condition. However, they needed to confirm this with evidence-based information to mitigate the likelihood of failure and extend the life of these high-risk assets, while at the same 48 | February 2021

For more field with information about a pipe’s construction to calculate information, visit: www.echologics.com the average minimum remaining structural pipe wall stiffness over the measured segment. The methodology employed is known as the cross-correlation method. As a pipe degrades, the velocity at which sound waves travel through the pipe decreases linearly, forming the basis for the technology. Pipe assessment is performed by bracketing a section of pipe between two sensors that are attached to an existing valve or pothole. An out-of-bracket noise is then created by tapping on a valve, or directly on the pipe, via a daylighting pothole. The field team measures the distance between the two sensors and proprietary software calculates the time taken for the acoustic signal to propagate between the two sensors. Wall stiffness is determined using the measured sound wave propagation speed through the pipe and comparing that value to the wave speed of a new perfect condition concrete pipe. This calculation takes into account the pipe and water properties for the specific classes of concrete pipe tested. For this particular project, all pipe properties were determined from drawings provided by the city.

Charlottetown reducing water use by 13% through metering and conservation

espite the population of Charlottetown, Prince Edward Island, continuing to grow, city officials say the introduction of water meters is significantly reducing local water consumption. The city’s annual consumption was at one of its highest points when it soared to 7.2 million cubic metres in 2008 under a flat-rate billing system. Yet, even as the population climbs towards 40,000, residents used one million less cubic metres of water when measured in 2019, following a settling-in period of the meter program. Municipal officials say the water metering program has almost been the equivalent of bringing in another wellfield to expand water capacity, and combined with new summer watering restrictions, has more than flattened the water demand curve, reducing consumption by 13% through all water conservation measures. “The Water and Sewer Utility has done an excellent job in field. It has four water pumping stations that consist of 18 subeducating residents, as well as offering incentive programs to mersible pumps. Some of the water infrastructure that was reduce water consumption,” said Charlottetown Mayor Philip installed in 1888 is still in existence. Brown.“The metering program puts control into the hands of the residents as they manage their own usage, which in many cases has resulted in decreased annual consumption,” he added. The city began rolling out a mandatory water meter program in 2015 (following approval in 2013) under the banner of “Take Control”. It had the initial target of having meters installed in all homes by the end of 2019. The concept was that people would think twice before turning on the tap and ease the longstanding burden around water levels in the Winter River, the city's main water source. The city also added its “Water Saver Champions” incentives so that residents could save up to $75 by recruiting a limit of three people to the metered system. Its $200 meter installation cost was also covered by the city, who contracted the meter program to Bevan Bros. Plumbing and Heating at a cost of $1.2 million. According to residents who have posted in online forums about their water bills, some have seen their bills drop by more than 20%. The city is currently charging an extra fee to the remaining 200 customers who don't yet have a water meter. These customers were being charged a $50 per quarter surcharge as an incentive to get metered. To further encourage these customers to get metered, the non-metered surcharge was scheduled to increase to $100 per quarter on October 1, 2020. "Customers who are still not metered will end up paying almost three times more on the consumption portion of their bill than the average metered customer,” city officials said in ® an announcement. Charlottetown’s water is extracted from 13 wells in three wellfields. In 2018, the utility completed the Miltonvale Well®

Hamilton conducts dead-end watermain flushing program using post hydrants By Danny Locco and Dave Alberton

amilton is a port city at the west end of Lake Ontario, with a water distribution system that goes as far back in history as the building of the waterworks in 1859. Today, Hamilton’s distribution system consists of two lake-based and four well-based sources that deliver water across 2,030 km of watermain through 24 distinct pressure zones, controlled by over 22,801 valves and with 13,568 fire hydrants. Coupled with a sprawling population and geographical features that divide the city, Hamilton has one of the oldest and most complex water distribution systems in Canada. Because of this, Hamilton Water is constantly thinking outside the box to keep up with regulatory changes and best management practices and make smart infrastructure upgrades and program updates to address multiple problems whenever possible. There are a few ways to ensure water quality is maintained through the system, once it leaves the treatment plant. The primary one is that the water continues to flow through the system without the opportunity to sit stagnant. Deadend watermains are the enemy in this scenario and unavoidable in old distribution systems. Typically, the older a city and the older the water infrastructure, the more dead ends will occur. In Hamilton, there are approximately 14,000 dead ends, 65% of which are not flushable because they do not have a flushing point, a hydrant or blowoff. Hamilton Water did an in-depth analysis, with options that included upsizing watermains, completing loops, installing blowoffs, adding more automatic flushers, or doing nothing. To keep water flowing, they installed a number of programable automatic flushing units in key locations with good success. However, automatic flushing units are large and noisy, so a lot of residents 52 | February 2021

Post hydrants ensure the dead ends are flushed and are a very important tool to complete water quality flushing in case of an adverse water quality incident.

don’t like to have one running daily near their house. At $12,000 to install, they are also expensive and are a big contributor to non-revenue water loss. With Hamilton’s dead-end watermains being only 100 mm in diameter, adding regular hydrants was not an option. The best solution was to add several post hydrants. These are mini hydrants, designed specifically for flushing deadend mains. They are small and unobtrusive, require little maintenance and are tamper-proof, which eliminates water theft and possible backflow contamination from such actions. It is anticipated that most dead ends will only require one flushing per year. However, as operators will be testing the water for chlorine residual during the process, they will determine which locations require more flushing and also fine tune the length of the flush. “The post hydrant allows us to gather data on pressure, either in real time with a gauge or historical trending with a

data logger. Such water quality parameters as chlorine residual and bacteriological samples can all be easily retrieved by use of a post hydrant,” said Paul Horton, water distribution technologist for Hamilton Water. The city has already installed 170 units since starting the program in May 2019, at an average cost of a little over $7,500 per unit. Suitable locations were chosen at the end of key watermains. Residents were contacted and site visits were conducted to choose the best site that was least obtrusive to residents and easily accessible to flushing crews. To maximize hydrant life expectancy, Hamilton Water requested the hydrant to be coated with 14 mm (or greater) of fusion-bonded epoxy-coated steel, both internally and externally. To endure the cold winter temperatures, hydrants are self-draining and non-freezing, with all working parts serviceable from above ground to prevent digging for maintenance or replacement. The installation

Environmental Science & Engineering Magazine

is straightforward with a 2 metre bury depth and takes the works crew approximately six hours to complete. A valve key is required to operate the hydrant after installation, preventing water theft. The post hydrants ensure the dead ends are flushed and are a very important tool to complete water quality flushing in case of an AWQI (adverse water quality incident) or water quality complaint. That said, they also have other benefits when it comes to managing the water system, which is what makes this project more than just another flushing program. Horton said: “When we are called upon to shut down a watermain for planned construction or when we are required to shut down a watermain for emergency repair, the post hydrant provides a means of draining the watermain and gauging the effectiveness of the shutdown. Upon returning the watermain back to service, the post hydrant being downstream of the last consumer, allows for a convenient point by which to flush water and check the water quality. In the absence of this, the watermain would have to be tapped and a copper section of pipe brought above ground level (grade) to undertake flushing and sampling after the repair.” It is not mandatory to flush dead ends unless they become a problem. Some smaller municipalities schedule an obligatory annual flush, while others turn a blind eye and focus on emergency repairs and maintenance. The more dead ends there are, the more enticing it is to do so. Hamilton’s flushing starts in the spring and continues through the fall (temperature permitting). Staff record how long it takes the flush from the hydrant to get to the operational guideline for chlorine residuals and records that information in the enterprise asset management (EAM) system to use for future reference. The frequency of flushing each hydrant can now be increased or decreased, based on trends from the EAM. This customized approach ensures each area meets optimal water quality requirements and also gives water operators an opportunity to record any maintenance issues that need to be attended to. Hamilton Water has taken a proactive www.esemag.com @ESEMAG

Some smaller municipalities schedule an obligatory annual flush, while others turn a blind eye and focus on emergency repairs and maintenance. The more dead ends there are, the more enticing it is to do so.

approach to not only address the historical situation of dead ends, but is committed to eliminating dead ends going forward and meet new standards by looping new watermain construction. The loop system has a 150 mm gate valve between the hydrant and where the 50 mm copper loop connects to the watermain. Operators can leave the valve open and flush the hydrant to ensure water quality or close the valve to directionally force the water through the loop and out of the hydrant. This enables operators to address the water services that are tapped off the loop, ensuring turnover of water and improved water quality. Hamilton Water plans to install 800 post hydrants, coupled with automatic

flushing units in key locations and to eliminate dead ends in new watermain construction projects. The city is confident it will stay ahead of tightening water quality regulations and most importantly ensure its residents receive the safest drinking water possible.

Robotic hydrodemolition equipment can speed up wastewater plant and industrial cleaning projects By Keith Armishaw

astewater and industrial facilities rely on high-pressure water-jetting machines for a number of specialized cleaning and removal applications to keep equipment operating at full potential. Enhancing efficiency for each task is vital for maintaining productivity and profitability. To help keep facilities running smoothly and optimize scheduled downtime, industrial cleaning specialists employ a variety of handheld and automated water-blasting equipment designed for these challenging applications.

done. It must include considerations for safety as well as productivity. Additionally, equipment that allows an operation to expand service offerings without further investment is the best choice for continued growth and overall stability. This has led a number of industrial cleaning contractors to invest in robotic hydrodemolition equipment from original equipment manufacturers (OEMs). These cutting-edge machines offer a number of safety and productivity benefits compared to handheld equipment or homemade systems and increase contractor flexibility over highly specialized, single-application options.

IMPROVED SAFETY Cleaning applications come with a number of inherent dangers. Limiting crew exposure to these hazardous conditions is a primary concern for contractors and has led to the development of numerous automated options. The extent to which these solutions keep workers out of harm’s way varies, as does the amount of personal protection equipment (PPE) required. Additionally, the use of automated equipment might be limited in some situations, unless they have access to powerful robotic equipment. For example, a contractor might be

Environmental Science & Engineering Magazine

able to perform a basic tank cleaning application with an automated system, such as a rotating jet lowered from the top of the tank. But, what if the project requires a more thorough cleaning or the removal of materials such as paint, coating or concrete? To achieve the necessary power for this type of cleaning, contractors often employ crews in full PPE wielding hand lances. This method significantly increases the safety risks for crews. Because they must constantly resist back thrust, hand lances cause workers to fatigue quickly. A worker using a 40,000 psi hand lance must constantly fight up to 52 pounds of thrust (at a flow of 5 gpm) for normal operation. The Waterjet Technology Association recommends, in ideal conditions, a single worker should not be required to withstand back thrust of more than one third their bodyweight for an extended period of time. In poor conditions, such as low light, uneven or slippery footing and confined spaces found in industrial cleaning applications,

These advanced units feature an innovative steel mast section with a reach of up to seven metres that can eliminate the need for scaffolding altogether. Additional mast sections can be employed to extend reach for larger projects as well. MAXIMUM PRODUCTIVITY Increased worker safety is only part of the equation when it comes to overall equipment effectiveness. Routine maintenance and cleaning, though necessary, is a costly undertaking. Minimizing the required downtime, then, must be a top priority. Among automated options, robotic hydrodemolition equipment has proven to provide optimal efficiency, where applicable. Specialized equipment for applications such as tank, scrubber, or heat exchanger shell cleaning are widely used, removing workers from some of the most dangerous and challenging jobs. But, these still require support crews that vary in size. A hydrodemolition robot, on the other hand, can perform many of the same applications with a single operator. This allows contractors to better utilize crews and maximize productivity across the jobsite. For removing concrete, paint, or other coatings, powerful hydrodemolition equipment again provides maximum productivity compared to hand lances. This is due to the robot’s ability to handle the higher water flow rates and reaction forces necessary for successful material removal. At 40,000 psi, hand lances can only safely offer 5 – 6 gpm for reaction forces up to 62 pounds-thrust. However, compact hydrodemolition robots can easily 56 | February 2021

For removing concrete, paint, or other coatings, powerful hydrodemolition equipment provides maximum productivity compared to hand lances. This is due to the robot’s ability to handle the higher water flow rates and reaction forces necessary for successful material removal.

handle 30 gpm for up to 312 poundsthrust of reaction force. The increased productivity offered by robotic hydrodemolition equipment means cleaning specialists and facilities can optimize operations during scheduled downtime. Contractors are able to complete cleaning applications faster and with less labour. SERVICE FLEXIBILITY Thanks to a variety of attachments from innovative OEMs, contractors can tailor hydrodemolition equipment packages to fit their current and future needs. For example, a number of OEM attach-

ments exist that allow for more efficient concrete or material removal in tunnels and pipes. In conjunction with the robotic equipment, these tools allow for consistent cleaning or material removal on uneven or oval-shaped passageways. Other attachments enable removal of concrete, paint, rust and coatings along an entire section of horizontal, vertical or inclined tunnels and pipes. Keith Armishaw is with Aquajet North America.

Restoring a natural waterbed for a green mixeduse community in Mississauga By Brian Sutherland

he western shores of Lake Ontario are home to many species of plants and animals distinctive to the area. However, because of its industrial history, the Mississauga region’s natural landscape has been suffocated in the past. Nevertheless, a key component of the region will be returned to its native state through a unique, extensive restoration project that will help revitalize its greenspace. Serson Creek, an important channel in Mississauga, will be restored

The creek is a key component of Lakeview Village, LCPL’s transformative 177-acre mixed-use community currently slated for development on Mississauga’s waterfront.

front. The restoration and revitalization of Serson Creek is a crucial milestone for the project and an example of how existing or historical natural elements can be revitalized and integrated into a community to enhance connectivity with the surrounding natural landscape. SERSON CREEK OF THE PAST Serson Creek is a highly engineered channel running through the Lakeview wetlands that was realigned and redirected in the 1950s. It currently runs southeast through an underground pipe beneath the G.E. Booth Wastewater Treatment Plant (WWTP) to Lake Ontario. The channel was redirected when the WWTP was built, to convey the majority of the drainage directly south between it and the Ontario Power Generation Lakeview Generating Station. SERSON CREEK OF THE PRESENT This unique restoration project will bring Serson Creek back to the surface. There are several guiding objectives for

IQ SensorNet’s NEW Alyza PO4 Orthophosphate Analyzer

ASSESSMENT To successfully restore Serson Creek, the existing channel was assessed and modelled to consider various obstructions, floodplain mapping and channel flow through analysis of the channel’s geometry, Manning’s roughness for the main channel, cumulative flow, and downstream boundary conditions. To reinforce the creek, the restored channel and surrounding habitat and plant infrastructure will benefit from reduced stormwaters through improved flow conveyance. This will be achieved through proper contraction and expansion coefficients for smooth transitions between cross-sections and the estab-

lishment of a trapezoidal-shaped channel with a range of bottom widths and depths to accommodate peak flows. To minimize channel movement in areas where Serson Creek will run through Lakeview Village’s business epicentre, the Lakeview Innovation District, bio-engineering design principles and armoring will be implemented. IMPLEMENTATION To support a thriving ecosystem in the surrounding natural heritage system, connectivity between Serson Creek and the greenspace in Lakeview Village will integrate a combination of habitats, including wetlands, woodlands, marsh, meadow and prairie, which were developed to reflect types of naturally occurring environments found near Lake Ontario. This will help the newly restored creek connect seamlessly with the surrounding region, as well as support the ecological connection between the community and the adjacent Jim Tovey Lakeview continued overleaf…

Lakeview Village site plan.

Conservation Area. The implementation of the Serson Creek restoration will occur in two consecutive phases. Phase 1A and 1B include constructing the interim connection between the lands adjacent to the Lakeview Village site and the conservation area through an existing ditch along the former rail corridor. As well, relocating a temporary haul road and bridge crossing is necessary. Phase 2 will include completing the ultimate conditions in which the remaining portion of the realigned Serson Creek will be connected with the Lakeview Village lands. SERSON CREEK OF THE FUTURE As of late 2020, several stages of the project have been completed. This includes the installation of erosion and sediment controls as well as the relocation of the temporary haul road, which is anticipated to be in use until 2024. Earthworks on the project are in the preliminary stage, with channel connection to be completed in the summer of 2021. This includes the majority of Phase 1A’s channel construction, stabilization and landscaping up to the connection at the adjacent lands, and construction of trails on the west side of the channel. 60 | February 2021

Following the completion of the foundational work outlined above, the subsequent stages will comprise significant berming and low-flow channel connections to the rehabilitated channel in order to flip the flow of the new corridor, as well as the installation of a storm sewer stub. In 2021, the project will also be landscaped. Looking forward to 2024 and beyond, the haul road and storm sewer will be removed, and the connection will be graded, resulting in the finished restoration.

A connection to the plant would be required via a utility crossing through Serson Creek. While the crossing details are not yet confirmed, the approximate locations of the crossing are included on the plans to ensure agencies are aware that there may be additional crossings of Serson Creek in the future.

Looking at key practices for control valve operation By Ryan M. Carroll

very control valve application is different. While rules and standards of practice exist for how they should be used, they are not always followed. Since it is installed after the pipe is in place, each control valve must be adapted to the specific application. With so many applications being unique to a utility, there are some best practices that every control valve operator should have in their toolbox before trying to tackle some of the more difficult concepts. All diaphragm operated, automatic control valves, regardless of the manufacturer, operate from the same hydraulic principles. Hydraulic pilots require differential pressure through the valve to operate. That principle is a foundation of how these valves work regardless of who makes them. The existence of a pressure gradient is essential to flow. A steel or brass fitting with a small hole is essential to the normal operation of a control valve. Without this, the valve won’t work. This fitting is the fixed restriction which reduces the flow of water to the top cover/bonnet through the pilot system. This allows us to direct the inlet pressure above the diaphragm, thus closing the valve. The pilot reacts to the pre-set pressure, allowing pressure to move downstream through the pilot plumbing, relieving pressure above the diaphragm, thus opening the valve. Proper start-up and control valve commissioning requires knowledge of the entire distribution system, not just the valve itself. While there are many questions that should be asked during valve commissioning, the most common error is lack of understanding of the rest of the system. For instance, if water and pressure are allowed to go downstream, can the infrastructure downstream handle that pressure? Will pipe come out of the ground? Will there be damages to residential or commercial properties when the valve opens? Take the time to know your www.esemag.com @ESEMAG

entire system before starting the valve. Pressure reducing hydraulic pilots can only be set in the field if there is pressure and demand on the downstream side of the control valve. For new control valves, it is easiest to have the hydraulic pilots set by the factory. However, repurposed valves may require adjustments in the field or a restart. When restarting pressure reducing valves, ensure the pilot can sense the downstream pressure before setting in the field. This requires demand in the system to see the pressure on the downstream side of the valve. Without demand, pilot adjustments will not register on a gauge and the pilot set point will be unknown or may not be operating correctly. Preventative maintenance programs are essential to ensuring full life from control valves. They should be put in place to exercise the isolation ball valves, check the condition of tubing/hoses, inspect for leaks, check the condition of the elastomers, ensure proper operation of the valve, and confirmation of pilot settings. Frequency will vary from valve to valve based on application, environment, water quality and usage. The first year of service should be used to determine the frequency of maintenance by conducting quarterly inspections and adjusting accordingly. Strainer blockage is the top reason pressure reducing valves fail, allowing higher pressure downstream of the control valve. A blocked or clogged strainer will stop water from flowing through the pilot system, affecting the ability to put water on top of the top cover/bonnet of the valve. When this happens, the main valve opens due to the control chamber not holding the inlet pressure. The pilot on a pressure reducing valve will shut and attempt to close the valve. However, as no water is available for the valve to close, high pressure will continued overleaf…

Standard Pressure Reducing Valve

Strainer blockage is the #1 reason for PRV failures

prevail and force the valve to fully open. Manual blowdown and higher capacity strainers are available for reclaimed, lower water quality and higher particulate water applications to help prevent this from happening. Pressure relief control valves, fire demand, and high flow valves absolutely need to be exercised to ensure they work when they are needed. Unless the system is being used for firefighting or an unusually large demand occurs, control valves may never open. Valves that spend the majority of their service life in a “just in case” scenario need to be exercised. This process involves forcing the valve open hydraulically (using the isolation ball valves to allow water off the top of the cover) and operating the valve for 5 to 10 minutes before returning the valve to the normal closed position. Biologic growth and turbidity may also affect the valve’s proper operation. Certain applications like this may consider an oxy-nitride treated stem to increase lubricity and ensure that the valve operates. Cavitation is not something that is caused by the type of valve. Rather, it is influenced by the water pressure at the inlet vs. the water pressure at the outlet. It occurs when the inlet pressure of a valve is decreased by 65% or greater on the outlet of the valve. Anytime there is an application that goes to the atmosphere or sub-atmosphere, it could occur. In these applications, there is no such thing as “eliminating cavitation”, but rather controlling how and where it takes place in the system, effectively dissipating the energy from the cavitation. Please consult your preferred manufacturer about options to help control cavitation. When integrating automation, instrumentation and electronics into automatic control valves, what happens when the power goes out? What will the control valve do if it is fully reliant on electric-

ity to function? It is a good idea to have hydraulic redundancy in applications, or at least know how to control a system to fail in a closed, open, or last position to protect the downstream infrastructure. Education is essential to the foundation, growth and development of any engineer, utility operator, or water management professional. There isn’t a school one can go to or a degree you can get that fully prepares anyone for the challenges of automatic control valves. Traditional education gives a basis for understanding operation, but doesn’t teach the finer points of the industry. For this reason, on-the-job experience and in-house training programs are usually the hallmark for education in this field. There are a number of control valve manufacturers who provide rich curriculums on applications and products in this field. Diaphragm operated, automatic control valves represent pieces of a larger picture within a water utility’s distribution system, which plays a significant role in the dynamics of how these innovative valves control water. In many cases, control valves are singularly responsible for the successful operation of multiple applications; from tank fill and sustainment of upstream pressure, to flow control and electronics integration. However, their operation is dependent on other appurtenances such as pumps, air release valves, and other equipment in the distribution system. Learning how each water distribution system works is paramount to understanding the valuable role control valves play in system stability, customer service and infrastructure maintenance. Ryan M.

WASTEWATER ter lagoons is that they require little operator attention compared to more advanced mechanical treatment plants. In situ systems can also share this advantage as they align well with the way wastewater lagoons are typically managed and don’t add complexity or additional processes to manage.

Installing BioCord reactors in a wastewater lagoon can dramatically increase capacity and performance without expanding footprint.

Five things to know about wastewater lagoon upgrades

astewater lagoons provide simple, reliable and relatively lowcost treatment for small and medium-sized communities. In Canada and the U.S., there are nearly 10,000 municipal lagoon systems and many more industrial, agricultural and commercial ones. Eventually, a community needs to improve the treatment capacity and performance of its lagoon system to accommodate growth and/or meet more stringent regulatory requirements. There are many options for technologies that can likely achieve the upgrade objectives. However, there are also several important aspects to consider to ensure that the system aligns well with the current operational process, at a price the community can afford.

pumps and blowers, which can substantially increase capital costs. In situ systems can be installed directly into the lagoon to enhance treatment capacity without expanding footprint or adding a large amount of supporting equipment.

CAPITAL AND LONG-TERM OPERATING COSTS Tanks, media beds, blowers and other equipment can all add capital and operating costs to a lagoon upgrade. Alternatively, in situ systems use the existing lagoon cell, which can reduce capital costs by as much as 50%. Energy demand for in situ systems can also be up to 50% lower by eliminating the need to pump wastewater to sidestream processes and replacing blowers with low-energy compressors. CUSTOMIZABILITY Like any wastewater system, lagoons can experience variable loading, changing flows, upset and more. Upgrade technologies should be easily adaptable to respond to short and long-term operating conditions, including anticipated changes to population and regulatory requirements. To achieve this, consider modular systems that can be brought online as needed or easily expanded to accommodate the needs of the community or business. BioCord reactors biological nutrient removal gives lagoon operators a simple and efficient way to dramatically increase capacity and performance of a wastewater lagoon or conventional activated sludge plant without expanding footprint. This low-energy, self-regulating process is ideal to help a plant achieve up to 99% ammonia reduction in difficult treatment conditions, such as during cold weather or when experiencing high-strength or variable loading. The fixed-film, modular process is like a condominium for bacteria on which preferred, naturally occurring bacteria can thrive. BioCord reactors offer a flexible, modular design that can be customized to fit virtually any secondary treatment process and handle anticipated flow and loading parameters.

ENERGY DEMAND Blowers can provide lots of air quickly, but the equipment is costly and has high energy demands. Some systems such as moving bed biofilm reactors also rely on coarse bubbles from blowers to circulate the carrier media and keep it in suspension, in addition to supplying air to the microbial population. But, larger bubbles are also less efficient at transferring oxygen to microbes. Much of the air simply bubbles up and out of the process tank. Instead, designers and operators should consider SIDESTREAM OR IN SITU TECHNOLOGIES a system that uses low-energy compresMoving-bed and submerged-bed sys- sors and micro-bubble aeration for sigtems typically add tanks or in-ground nificantly higher oxygen transfer and cells to accommodate the new treat- lower, more efficient energy usage. ment process.
