In many ways televison can educate the public better than we can

As many involved in the wastewater industry have experienced, there is often a puzzled look from your audience when you describe the field you work in when social situations lead to discussions of occupation.

If we get past the “ick” factor, I often get asked to elaborate on what exactly the wastewater industry is all about. Most people are fascinated to learn that the wastewater industry in Canada is well over 100 years old and is of vital importance in protecting public health, water quality and the overall environment.

In our modern society, there are vital functions that are needed, that are not at all glamorous, or even palatable to most. “Dirty Jobs” is an American television series that ran for eight seasons until 2012. In each episode, a worker or team of workers took on the star of the show Mike Rowe as a fully involved assistant for a typical work day. Rowe would work hard to complete every task as best he could despite discomfort, hazards, or repulsive situations.

Apparently, when asked what was the grossest dirty job he ever tried, Rowe said it was as a sewer inspector. He said that “aside from sloshing through a relentless chocolate tide, inspectors encounter a myriad of man-made products that shouldn't be flushed down toilets— along with roaches the size of thumbs and rats the size of bread loaves. It's hot, dirty and too smelly to describe.”

An article in this issue (See page 36) describes “Sewer Divers”, which is a new series from the Discovery Channel that takes viewers on a journey through sewer systems in several major cities as they tackle clogs and broken pipes.

Highlighting the challenges of the dirty job, as well as the age of the deteriorating infrastructure, the show goes to great lengths to show how workers keep systems running and toilets flushing.

Climate change is now an everpervasive topic. In the summer months especially, the news is dominated by forest fires, flood and storm events, which are exacerbated by it.

“Apocalypse Plan B” is a film about climate cooling ideas by Mark and Caitlin Starowicz, that features debate between host David Suzuki and Canadian-born Harvard physicist David Keith. Keith has proposed spraying the stratosphere with massive amounts of aerosol-like sulphur to reflect away sunlight.

Dr. Sarah Doherty of the University of Washington was inspired by satellite images of lines of bright clouds over the oceans, directly over the path of freighters and other large vessels. Dr. Doherty reasoned that this smokestack

emission-caused phenomenon could be replicated with benign salt spray instead.

Apocalypse Plan B also profiles NASA’s Dr. Lola Fatoyimbo, who studies forests from space, and graphically demonstrates how they clean the skies.

“We’ve got an existential choice,” says Starowicz. “Radical climate intervention through geoengineering, or radical global restoration of ecosystems”.

I look forward to watching Sewer Divers to witness the practical use of technology and human endurance. I also want to watch Apocalypse Plan B, to learn about the theoretical and global scalability possibilities profiled in it to address climate change.

Calgary’s new Shaganappi Pump Station designed for energy efficiency and resilience

By Andy Barr

The Shaganappi Pump Station is the largest and most critical of the City of Calgary’s 42 drinking water pump stations. The facility provides safe and reliable drinking water to over 200,000 citizens in the city’s North Hill and Glendale Pressure Zones in the northwest, as well as critical institutions such as the Foothills Hospital and the University of Calgary.

The original Shaganappi Pump Station was constructed in 1977, serving Calgary for many decades. In later years, it began to experience mechanical and structural issues. An investigation determined that replacing the pump station would be more cost-effective and efficient than repairing or rebuilding the facility in its original location.

In 2015, the City of Calgary retained Associated Engineering (AE) to assist in site selection, and provide design and construction services for a new pump station. The selected site for the new pump station was a city-owned greenspace adjacent to the Bow River. The site was chosen primarily for its proximity to the original pump station and existing large diameter water feedermains. This would facilitate connecting the new pump station to the existing piping.

Since the new pump station serves established neighbourhoods, it was designed at its maximum buildout capacity. Flows were not anticipated to change due to increased growth and demand.

Having extensive operating data from the original station was advantageous, particularly typical pump flows and hydraulics. With this information, the AE team designed the pumps to achieve their highest efficiency for the most frequent operating conditions, rather than at peak operating conditions. This maximizes energy efficiency over the life cycle of the station.

The new facility includes three 447 kilowatt pumps rated at 100 million litres per day and three 447 kilowatt pumps rated at 30 million litres per day, pumping into the North Hill and Glendale Pressure Zones, respectively.

Pumping equipment is housed in a single-storey building, designed as a “post-disaster” structure using resilient materials, such as concrete columns and steel trusses. Given the proximity to the Bow River, the team considered climate change, and revised flood zone mapping available from updated flood modelling. The building was designed to resist flotation.

The new pump station was also designed for ease of use by maintenance and operation staff. An emergency generator was included in the design to facilitate pump operation should the utility’s electrical supply be interrupted.

This site is close to a public park, bicycle path, condominium and businesses. Therefore, limiting the impact of noise from the facility on nearby residences and park areas was important.

Noise reduction measures for the new Shaganappi Pump Station included concrete block wall construction, heavy duty noise-cancelling overhead doors, duct silencers on the cooling air intake and exhaust louvres, and a super extreme grade exhaust silencer.

Noise reduction measures included concrete block wall construction, heavy duty noise-cancelling overhead doors, duct silencers on the cooling air intake and exhaust louvres, and a super extreme grade exhaust silencer.

Connecting the new facility to the existing feedermain network was one of the most technically complex aspects of the project. This work needed to be completed in a tight three-month time frame, during the city’s low water demand period, but avoiding the main freeze up period from January to February.

The facility’s 1350-mm diameter suction, 1200-mm diameter north discharge and 900-mm diameter south discharge steel piping from the new station were connected to the existing concrete piping from the old pump station.

To retain the contractor, the city used a request for proposal process, rather than conventional tender. This meant a better understanding of the contractor’s proposed work plan and approach, considering the site constraints, traffic and public areas. Graham Infrastructure was awarded the construction contract and partnered with Whissell Contracting to complete the underground scope of work.

Extreme rainfall could add $700M per year to municipal storm, wastewater costs

By ES&E Staff

Without further adaptation to climate change, a new report warns that more extreme rainfall in Ontario could add $6.2 billion to the costs of maintaining storm and wastewater infrastructure by 2030. The Financial Accountability Office of Ontario (FAO) projection is a 27% increase above a “stable climate scenario”. This means the province will spend an average of $3 billion per year over the century to bring these assets into a state of good repair and maintain that state.

This includes stormwater assets such as pipes, ditches and culverts, as well as wastewater assets like sewer pipes and sanitary force mains belonging to the province’s 444 municipalities, and valued at $124 billion.

The December FAO report, Costing Climate Change Impacts to Public Infrastructure: Linear Storm and Wastewater, states that as extreme rainfall increases, un-adapted assets will increasingly face capacity constraints, raising the flood risk to surrounding areas. On an annual basis, extreme rainfall caused by climate change could cost municipalities in Ontario an additional $700 million a year to maintain storm and wastewater assets.

Peter Weltman, the province’s financial accountability officer and author of the report, said Canadians will really see the impacts of climate change around 2050 if significant action isn’t taken.

Under consistently extreme rainfall, pipes and ditches will require more frequent and costly inspections and preventive maintenance, as more debris, sediment and vegetation are expected to enter stormwater systems. Channel protection will also be subject to accelerated erosion.

For wastewater, increased intensity of short duration rainfall events will increase the inflow of surface water into sewer pipes, while increased intensity of longer duration events will cause groundwater to infiltrate sewer pipes.

For sanitary force mains, more extreme rainfall will result in higher inflow and infiltration, increasing the volume of wastewater being conveyed to treatment facilities, as well as the pressure required to do so.

The FAO report states that adapting assets to climate change can mean increasing their capacity or incorporating source control measures such as green infrastructure. However, climate action also comes at a cost, representing a financial increase between 29% and 53%, albeit lower than the cost of inaction, the report states.

“Regardless of which asset management strategy is pursued, the future path of global climate change will be a key determinant in the extent of additional climate-related infrastructure costs,” states

the FAO report.

In terms of further emissions impacting assets, a medium emissions scenario, where global emissions peak by mid-century, could mean an additional $1.1 billion per year to maintain assets. In a high emissions scenario, where global emissions continue rising throughout the century, these maintenance costs could increase by $1.8 billion per year.

Understanding the impacts of FOG on wastewater systems

By Daryl Mandoza

Fats, oils, and grease (FOG) can dramatically reduce efficiency while increasing the operational costs of a wastewater treatment system. Food processing facilities in particular often experience buildup of grease deposits or caps in their lift stations and piping.

A complex chain of events occurs to create FOG deposits. This involves cooled water, hydrolysis (splitting of chemical bonds), and saponification, all of which lead to the buildup of FOG deposits in lift stations and underground piping.

FOG buildup can require the need to clean facility piping to ensure water is moving efficiently. An accumulation of FOG in lift stations or collection pits may need to be removed to restore treatment capacity. Disposal of collected FOG can be a one-time fee and up to $500 or an annual service fee for scheduled removal, with price ranges varying.

Failure to treat FOG in lift stations or piping can result in odours as it breaks down. As the FOG decomposes, bacteria in the water release pungent nitrates and rotten-egg-smelling sulphates as they digest it. These odours can lead to consumer complaints, causing loss of goodwill and the incurred cost for odour control treatment.

If left untreated, FOG can increase the need for repairs or replacement of equipment, while escalating degradation of existing system infrastructure.

There are several solutions to protecting and maintaining wastewater systems. Removal of FOG in the production stage can prevent the need to treat downstream. In some cases, a gravity grease interceptor can be used to remove FOG prior to additional treatment or discharge. Source grease traps identify and treat for FOG at specific high FOG areas and remove them before they make it to the waste stream.

It is important to evaluate cleaning and sanitation preventative maintenance programs to mitigate the impact of FOG on your wastewater treatment system. The implementation of a supplemental bioaugmentation program with microorganisms specifically selected and blended to reduce FOG buildup is effective. It provides an effective quick reduction of the existing fat cap, as well as enough bacteria to mitigate future FOG buildup.

Incorporating any of these solutions will help reduce operational cost, as well as capital expenses a facility may be experiencing. A comprehensive analysis of the treatment process with a water treatment expert is the best way to determine the level and type of solution that best meets a facility’s needs.

Food processing facilities often experience buildup of grease deposits or caps in their lift stations.

Manitoba invests millions in wastewater upgrades

By ES&E Staff

Manitoba has announced more than $34.4 million in funding, primarily for a series of wastewater management projects. The largest of the upgrades consists of $9.1 million in federal and provincial funding to expand the City of Dauphin’s lagoon reactor system for ammonia reduction and disinfection in the west of the province. Dauphin officials, who are contributing $3.3 million to the upgrades, also plan to add a new sewage treatment facility and new pipes.

“We identified the need to expand our lagoon over a decade ago, so we are excited to see this investment through the Investing in Canada Infrastructure Program for the project. Completion of the lagoon expansion will allow Dauphin to grow our population and industry,” announced Dauphin Mayor Christian Laughland.

Dauphin’s lagoon system is designed for a population of 11,000 and has a production capacity of 8.8 megalitres per day. Water is treated through flocculation, ozonation, disinfection

and sedimentation. The total capacity of the system is approximately 891 megalitres, and it is currently operating close to capacity.

Another project made possible with the new funding will be upgrades to the wastewater treatment system in Neepawa, just two hours west of Winnipeg.

The system will be expanded and upgraded to increase capacity for wastewater and stormwater. The total federal and provincial investment of $4.2 million involves implementing a moving bed biofilm reactor system, upgrading the treatment building, adding a lab, as well as decommissioning the primary and secondary lagoon cells. Neepawa officials are contributing $1.5 million to the upgrades.

Other major lagoon projects will take place in Russell-Binscarth, where municipal officials will invest more than $8 million to update the lagoon site and undertake a partial demolition and reconstruction of storage cells.

The community of Glenboro – South Cypress will invest some $5.5 million to upgrade its current facultative lagoon, which consists of a primary treatment cell and secondary exfiltration cell that discharges into the Assiniboine Delta Aquifer. It will become an aerated primary cell, with two submerged attached growth reactors.

Upgrades will also be made to water and wastewater pipes in Killarney-Turtle Mountain, as well as sewer lines in Prairie View.

Lastly, the District of Pinawa landfill will undergo an expansion to include an area for electronic waste, scrap metal, paint products, as well as used oil and tires. Phase 3 will include an area for composting.

Canada reaffirms maximum concentration for antimony in drinking water

By ES&E Staff

Canada is proposing a risk-managed approach that would reaffirm a maximum acceptable concentration (MAC) of 0.006 mg/L (or 6 µg/L) for antimony in drinking water that was developed in 1999.

Antimony (Sb) is a metal naturally present in small quantities in water, rocks and soils. It can be harmful to the gastrointestinal system and the liver, as well as the eyes and skin, and cause problems with the kidneys.

The MAC for antimony is being revisited by the Federal-Provincial-Territorial Committee on Drinking Water, particularly in relation to private wells and for small systems, where some have suggested that lowering the MAC could significantly increase health protection.

The proposed guideline technical document, however, suggests that lowering the MAC would not provide additional protection, although its authors note that they will continue to monitor new research in the area and recommend any changes.

“At the municipal level, treatment technologies that are available to achieve antimony drinking water concentrations below the proposed MAC include coagulation, adsorption, membrane filtration and coagulation followed by ultrafiltration,” states the newly-proposed guideline.

In water monitoring data obtained from the provinces, antimony detection frequency was very low, indicating that a large number of the samples had antimony concentrations below the detection limit, states the document published in the December edition of the Canada Gazette.

The National Drinking Water Survey of Canada had maximum antimony concentrations below 1.0 μg/L during the summer months, but had some higher concentrations in the raw and treated lake water during the winter months. There were slight differences between raw, treated and distribution system waters.

Monitoring for total antimony and other contaminants (e.g., iron, manganese, arsenic, lead) should be conducted when water quality changes or physical disruptions occur in the system, recommends the guidance document.

“The release of antimony and other contaminants may be indicated by the presence of discoloured water or increased turbidity resulting from the release of deposits or scales present on the pipe wall,” states the guideline.

Antimony can come naturally from windblown dust, weathering of mineral rocks, predominantly sulphides and sulphosalts, or volcanic ash. It can also come from coal combustion, including mining and smelting, or from busy vehicle areas in the form of abrasions in tires and brake linings.

Antimony, minimally produced in Canada, is absorbed by the roots of vegetables and other crops grown on antimony-containing soils; however, dietary exposure to total antimony is low. Polyethylene terephthalate (PET) food pack-

aging materials, such as trays and bottles, may also contribute to antimony in food, the new document states.

Other sources of antimony include fire retardants, shooting ranges, pharmaceuticals and pesticides. It may also enter drinking water from plumbing solders in drinking water distribution systems.

Over 200 inorganic compounds of antimony exist in the environment, with stibnite being the most abundant, followed by the oxides of antimony and the antimonides of heavy metals, with arsenic being the most predominant.

At the residential scale, certified treatment devices relying on reverse osmosis and distillation have proven most effective for the removal of antimony.

Fibre balls in the fight against micropollutants

By Greg Smith

One of the ways that microplastics (measuring five micrometres to five millimetres) and trace substances can be removed from wastewater is by adding activated carbon powder to the water in a contact tank.

Activated carbon, with its porous and brittle structure, has a large internal surface area. In physical terms, one teaspoon of activated carbon powder has the same surface area as a football field. This surface area provides lots of room for the trace substances to accumulate. The activated-carbon-enriched water is therefore kept in the contact tank for 15 to 20 minutes.

In conventional wastewater treatment plants, a sedimentation tank is also required to remove the activated carbon from the water after this purification process. It falls to the bottom of the tank and, together with the attached trace substances, is later separated with the sewage sludge.

Studies have shown that this method

removes 80% of the pharmaceutical residues and X-ray contrast agents from the wastewater. Wastewater treatment plants without this fourth purification stage only hold back around 30% of the trace substances collected.

However, removing 80% of the micropollutants was still not enough for one town, so it opted to install Fuzzy Filters® from Bosman Water Management. The company claims that this filter system can eliminate as much as 95% of all trace substances and also remove microplastics and phosphorus from the wastewater. The core of the filter system is formed by the Fuzzy Filter balls, which are made from synthetic fibres and shaped into a sphere, with a diameter of around 33 millimetres, using a clip.

Unlike conventional filter systems, the liquid to be filtered flows both around the outside of the filter material as well as through it. The suspension to be filtered flows into the distribution chamber under the filter bed. In the distribution chamber, inflowing water is evenly distributed over the filter surface before it flows through the lower fixed perfo-

rated plate and into the filter bed.

Micropollutants absorbed by the activated carbon, as well as the phosphorus and microplastics that fell to the bottom of the tank, are collected in the filter bed and the filtered water flows back out the top of the Fuzzy Filter.

As soon as a specified turbidity value or predefined maximum pressure is reached in the filter bed, a backwash cycle is started. Backwashing involves pumping raw water into the filter while an external fan blows in purge air to set the filter medium in motion. The filter balls, which move freely between the perforated plates, are set into motion by the air flow. Contamination particles adhering to, and stored in, the filter are thus loosened and flushed out.

The activated carbon is pumped back into the aeration tank with the backwash water and a further purification process is started, since the activated carbon may still be holding micropollutants after the first flushing cycle. After one purification cycle, the amount of trace substances is reduced to a fraction of what it was originally.

The butterfly valves and gate valves, which allow wastewater containing the micropollutants to flow in and the purified water to flow out, are automatically opened and closed using FESTO pneumatic DAPS quarter and DLP linear actuators. Other butterfly valves and gate valves, in combination with the pneumatic actuators mentioned, supply the purge air and open/close the sludge outlet. Automated gate valves are also used in the small pumping station that pumps water from the biological clarification stage into the fourth purification stage.

Gatineau water plant pressure losses highlight boil water notification process

By ES&E Staff

Gatineau residents have the option to register for a digital notification.

Some 35,000 water customers in the Quebec Village of Gatineau were recently under a boil water advisory due to a depressurization issue at the local water plant, just one week after a similar situation left millions of customers under a boil water advisory in Houston, Texas.

The Gatineau depressurization in December 2022 was caused by a “mechanical malfunction”, local officials said, while the Houston event was caused by a power outage.

Pressure drops, generally speaking, are caused by issues with pump malfunctions or lost power; however, sometimes one of the water lines or mains may have had a break or failure.

“Gatineau will not take any chances in those cases, and asks everyone to boil their drinking water as a preventive measure before consuming it, until the test results are out, which generally takes 48 hours,” local officials stated on the municipality’s website. “If the tests are negative, the boil water advisory is lifted. If the tests are positive, Gatineau issues a regulatory advisory.”

!"#$%&'($%)#%*"$

!"#$%&'()*$)+#(&,)$*$%&-"".)*$+&.')$(+/0

Gatineau public works repaired the water main and lifted the advisory within 24 hours after lab test results found no bacteria. Houston needed more time to process its lab water samples for the Texas Commission on Environmental Quality, eventually lifting the boil water advisory after some 36 hours.

The advisories in both recent cases were considered preventative, as the drop in pressure increased the potential for contaminants to be introduced, as well as the risk of backflow. A pressure loss is typically defined as the pressure having dropped below 20 psi.

In Gatineau’s case, however, the potential for a pressure loss or interruption in the water supply was foreseen, and officials sent out preemptive notifications almost one week in advance of the repair. In Texas, the situation was more unexpected, particularly in terms of the plant not being able to access backup power.

How customers are notified in these situations has also drawn scrutiny since the Houston situation, where many local residents were critical of how the boil water notice rolled out. Initially, it was communicated through an evening media advisory and a post on Twitter. However, many residents said they did not learn of the notice until the following morning, when news outlets announced that local schools would be closed.

While Gatineau officials posted on Twitter as well, they also give residents the option to register for a digital notification system that alerts users through text, email, or phone message in the case of water events or other urgent situations. In the case of water, the notifications could cover current boil water advisories, temporary water shut-offs, no water use advisories, or even the testing of fire hydrants.

What can you do with adaptive wastewater mixers?

Flygt introduced the first submersible mixer in 1951 and today, more than 250,000 have been deployed. However, they are often given little consideration in the overall design and operation of wastewater facilities, and are generally selected for worst-case scenarios, based on flow or loading.

Because the need for mixing varies greatly in the course of any given treatment cycle, the result is overmixing, a practice often employed to address the worst-case scenario. In other words, to avoid the risk of under-mixing, engineers design for seldom-occurring peak conditions of maximum plant flow or maximum load, setting aside more common average conditions, and mostly ignoring minimum conditions. Unfor-

tunately, this practice wastes energy and often results in a sub-optimal process.

Seeking more efficient mixing, wastewater treatment plant operators are increasingly turning to mixers with integrated variable speed control, which can dramatically lower energy use and reduce wear. Unlike traditional single-speed mixers that always have to be operated at 100% capacity, regardless of how much mixing is actually needed, Flygt adaptive mixers are designed to automatically adjust to a wide range of operating conditions.

With a growing focus on nutrient removal, energy management and optimization, mixers present an extraordinary opportunity for improvement for most wastewater treatment facilities.

MIXING BASICS

Mixing is performed in many stages of wastewater treatment to ensure blending, suspension and/or distribution. In order to provide adequate mixing, the energy from the mixer must be imparted to the liquid to create a bulk flow loop throughout the tank. The amount of energy is measured in terms of newtons (N) and is referred to as thrust (the standard for measuring thrust in submersible mixers is ISO Standard 21630:2007).

For example, as a mixer propeller exerts a thrust on liquid contained inside a tank or vessel, the liquid will start to move and accelerate until the losses associated with the flow in the tank balance the mixer’s thrust. The velocity attained at the balance point is the “equilibrium velocity.” Higher thrust

equates to higher equilibrium velocity, resulting in more intense mixing.

It should be noted that mixing can be achieved with almost any rotating device, provided that unlimited power is available. The thrust produced by a mixer and its associated power draws, however, are the key performance parameters of a submersible mixer. Among a set of comparable mixers, the mixer that produces the most thrust using the least power is the most efficient mixer. Efficient mixing, using the lowest amount of power, requires an optimally designed mixer.

WHAT IS ADAPTIVE MIXING?

To put it simply, adaptive mixing is adjusting the mixer’s speed so that the required output (thrust) matches the changing conditions. With adaptive mixing, the mixer is NOT always running on one previously determined set speed. The speed varies as the need changes.

WHY ADAPTIVE MIXING?

Wastewater treatment is not a static

process and therefore a mixer’s thrust should not be either. Mixing requirements vary over time depending on a range of factors, including flow rates,

input aeration rates, seasonal variations, etc. Conventional mixers that operate at a fixed output often result in turbulence,

In wastewater plants, mixers can be added to reduce the demand on aeration equipment.

wasted energy, unnecessary wear on the mixer, and increased maintenance due to inefficient operation of the mixer.

Adding variable thrust technology to a submersible mixer allows operators to efficiently adjust mixing thrust to meet varying application demands, thereby enhancing operational capabilities while reducing mixing energy costs. Variable speed capability allows for continuous thrust variation to be acquired while operating more reliably than manual “switch-on/switch-off” practices. Energy savings may be gained through automated operation of mixers when the produced thrust is set to what is required.

With an adaptive mixer, thrust (and associated power draws) can be simply increased or decreased to meet the current thrust requirements. Operators can modify the output by way of a tankside control panel, a programmable controller or plant-wide SCADA system to match mixing needs.

While some plants install tank-side variable-frequency drives (VFDs) to

achieve some operational flexibility in a single speed mixer, Xylem has engineered a drive integrated with the mixer’s submerged motor. As such, electromagnetic compatibility issues and other installation, commissioning and operational issues often associated with installing external, tank-side VFDs are eliminated.

Integrated drive technology coupled with the mixer’s hydraulically optimized propeller work effectively to meet process objectives.

Integrating the variable frequency drive into the mixer makes the mixer/ VFD combination very compact and simplifies operation, installation and commissioning. By adjusting mixing to actual process conditions, the integrated VFD also results in a more efficient mixer, and the lowest life cycle mixing energy costs.

IMPROVED PROCESS RESILIENCY

Flygt adaptive mixers let operators adjust output, manually or automatically, to achieve the required mixing process result. With the Flygt Dirigo® technology platform, adaptive mixers can self-monitor. When an adaptive mixer senses a near overload condition, instead of shutting off, it slows itself down, so the process is still up and running. That’s a great benefit in terms of process resiliency and compliance.

APPLICATION OPPORTUNITIES

Mixers of different designs deployed in aeration basins, sludge storage tanks and other treatment processes have varying

degrees of effectiveness. They can also be significant consumers of energy, especially if operated in an “always on” mode.

Because treatment processes are variable, mixers should be too. Adaptive mixing technology is an effective solution for a variety of water and wastewater treatment processes. With the introduction of full automation capabilities, plant owners and operators are assured simplicity and reliability in a variety of treatment processes, including the following:

Secondary treatment – Air flow has become a crucial parameter used to control the level of treatment and also to reduce the amount of energy needed for aeration applications. As load increases, air increases and as loads are reduced, air flow is reduced and with that, mixing energy can also be increased or decreased to save energy.

Mixers can be added to reduce the demand on the aeration equipment. This not only reduces the amount of energy used, it also decreases the amount of air in the tanks and improves processes.

Enhanced biological phosphorus removal (EBPR) – EBPR is utilized when phosphorus discharges below 1 mg/l are required. Side Stream EBPR (S2EBPR) is a type of EBPR where a portion of the RAS is conveyed to a separate tank to allow for fermentation. Whether the EBPR is performed within the process flow or in a side stream, the creation of volatile fatty acids (VFAs) and anaerobic zones are paramount for successful phosphorus removal.

Adaptive mixers provide process control in these systems by providing slow, non-air-introducing mixing. In addition, the thrust from adaptive mixers can also be increased to re-suspend and move fermenting sludge blankets, when needed.

Biological nutrient removal (BNR) –BNR is the most common application for mixers in wastewater treatment. Proper mixing within anoxic and anaerobic zones can help ensure improved treatment efficiency and lower effluent nutrients. Being able to vary the speed of the mixing in treatment processes will improve the BNR

process, reduce energy requirements, and save money.

Sludge holding – As wastewater treatment plants become larger and more sophisticated, so do the demands for handling large amounts of sludge, which is an expensive and complex operation.

For tanks at wastewater treatment plants that contain solids slurries, either for anaerobic digestion or sludge storage, mixing is a key factor in the proper design, operation and maintenance of the system. Submersible mixers are often used in sewage treatment plants to keep solids in suspension in the various process tanks and/or sludge holding tanks.

Adaptive mixers can be used to increase and decrease the applied thrust based on fluctuations in sludge concentration and/ or sludge levels in the tanks.

Pilot Butte, SK upgrades its wastewater treatment lagoons

By Kelly Paul, Philip Wiebe and Tanner Devlin

Pilot Butte was becoming a substantial bedroom community because of its 10 km proximity to Regina. In 2014, with developers and prospective homeowners alike investing, and with the town’s population rapidly exceeding 2,500, the municipality needed to upgrade the existing two-cell facultative lagoon system to allow for more treatment capacity.

Around the same time, Boggy Creek, which is part of the Qu’Appelle River watershed and where Pilot Butte’s existing lagoons had been bi-annually discharging, had been reclassified by regulators. A downstream use and impact study examined the effect the treatment plant would have on Qu’Appelle River ecological systems, and established the new effluent targets. Therefore, the upgraded treatment system needed to meet more stringent effluent limits, in addition to expanded capacity.

Overall, it was determined that the system would need capacity to serve 7,500 citizens. It also has to treat a design influent flow of 3,550 m³/day (0.94 MGD) to <10 mg/L five-day carbonaceous biochemical oxygen demand (cBOD5), <15 mg/L total suspended solids (TSS), federal wastewater systems effluent regulations (WSER) inspired non-toxicity requirements of <0.2 mg/L of un-ionized ammonia, <10 mg/L of total nitrogen (TN), and <1 mg/L of total phosphorus (TP).

IDENTIFYING THE SOLUTION

Pilot Butte’s engineers completed an evaluation of treatment technologies that could meet the expanded capacity and new effluent limits. A major consideration during evaluation was that a municipality going from facultative, seasonal discharge ponds would be accustomed to low operating and maintenance requirements.

Therefore, it was important that any upgrades comprised simple and reliable

technologies. Working together with Nexom’s Winnipeg-based lagoon process team, the project engineers designed a solution that would enable Pilot Butte to maximize the use of their existing lagoon infrastructure without sacrificing the operation and maintenance simplicity, to meet additional capacity and more stringent effluent limits.

COLD CLIMATE CONSIDERATIONS

A new constant-level primary lagoon cell with optAER® aeration equipment was constructed in front of the two existing facultative lagoons. The existing facultative lagoons were converted to variable-volume storage cells 1 and 2.

Although the upgraded system would switch from bi-annual to continuous seasonal discharge, there was still a need to store water in the coldest winter months, when the receiving body would freeze and prevent the possibility of year-round continuous discharge. Therefore, a new vari-

able volume storage cell 3 was constructed to provide adequate storage capacity for the expanded design population.

Two new SAGR® cells were constructed to provide final treatment of storage cell effluent prior to discharge. Positive-displacement blowers were installed to supply air to the optAER and SAGR systems.

IMPLEMENTING NITROGEN REMOVAL

Both facultative and aerated lagoons are cost-effective solutions for removing pollutants, such as cBOD5 and TSS, found in wastewater. Implementing a primary aerated lagoon cell followed by three variable-volume storage cells was the first step that would allow Pilot Butte to maximize the use of its existing infrastructure without increased operation and maintenance requirements.

However, lagoons alone can struggle with ammonia removal. Its removal is required to meet WSER effluent non-toxicity requirements, since >0.2

mg/L un-ionized ammonia can be toxic to freshwater organisms.

It is well known that nitrifying microorganisms, which are responsible for ammonia removal by oxidation to nontoxic nitrates, are inhibited in lagoons as the water cools. This happens for multiple reasons, but mainly that ice formation prevents atmospheric oxygen transfer in unaerated ponds. Thus, the metabolism of nitrifying microorganisms slows down significantly as water temperature cools below 5°C, and the hardier heterotrophic microorganisms, the microorganisms responsible for cBOD5 removal, outcompete nitrifying microorganisms.

For these reasons, the SAGR nitrification process was installed after the storage cells as the final treatment stage. The two SAGR cells provide an ideal environment for nitrifying microorganisms to thrive despite water temperatures of <1°C. Water flows horizontally through the SAGR’s fully aerated coarse rock bed. The nitrifying microorganisms grow as a biofilm on the rock and the high-DO environment created through aeration encourages high rates of ammonia removal despite low water temperatures.

Although the SAGR cells convert ammonia to nitrates and detoxify the wastewater, the residual non-toxic nitrates from the nitrification process still contribute to effluent TN. Nitrate is removed through denitrification, which is a biological process that utilizes the same heterotrophic microorganisms already found in conventional aerated lagoons.

Typically, the heterotrophic microorganisms would use oxygen to remove cBOD5. However, if oxygen is limited and nitrate is supplied to the lagoon instead, those heterotrophic microorganisms will utilize nitrate to remove cBOD5. As a result, nitrate is reduced to nitrogen gas, resulting in simultaneous TN and cBOD5 removal. An additional benefit is that the energy required for aeration to supply oxygen to the lagoon is reduced since the heterotrophic microorganisms utilize nitrate rather than oxygen.

Nexom utilizes a nitrified effluent recycle to accomplish denitrification, and therefore TN removal, in lagoon-based treatment systems. A portion of the fully-nitrified SAGR effluent, which contains

nitrate, is continuously recycled to the primary lagoon cell. There, it combines with untreated influent, creating an environment rich in cBOD5 from the untreated wastewater and nitrate from the SAGR effluent. These conditions promote a highrate of denitrification in lagoon cells where heterotrophic microorganisms work to remove both cBOD5 and nitrate.

RETROFITTING PHOSPHORUS REMOVAL

There are many ways to remove phosphorus from wastewater. However, many biological and/or filtration-based systems would dramatically increase the complexity of lagoon-based systems. Therefore, to address the <1 mg/L TP limit most simply, a chemical dosing system utilizing alum, ferric or equivalent was installed.

The trivalent metal from alum or ferric solutions binds both directly and indirectly with phosphates, the primary fraction of TP in wastewater. The bound phosphates then settle out in the lagoons with the chemically formed floc, resulting in TP removal from the liquid stream. Settled chemical sludge is ultimately removed from the system with the settling organic sludge during desludging operations.

SITE CONSTRUCTION AND PERFORMANCE TO DATE

The retrofit of Pilot Butte’s existing two-cell lagoon began in late 2019. To avoid disruption of the existing ponds,

the new primary cell and SAGR cells were constructed to the west of the existing cells, while the new storage cell was constructed to the south. The design site layout left room to build another primary lagoon cell, another storage cell, and another set of SAGR cells should the town wish to effectively double the plant’s capacity from 3,550 m³/day to 7,100 m³/day.

Nitrification, denitrification, and phosphorus removal systems were commissioned in the summer of 2021, with engineers and Nexom field personnel on-site to provide training on the blowers, lagoon aeration system, and SAGR process. The system completed its first critical fall discharge since commissioning in 2021, as well as another full season’s discharge in 2022.

The system performed as expected, producing fully compliant effluent throughout the discharge periods. Measured effluent TN was as low as 1.9 mg/L in 2021 and varied from 4 mg – 6 mg/L throughout the 2022 discharge season, which was well below the 10 mg/L TN limit. Overall, Pilot Butte was more than able to meet their effluent limits, all while maintaining the ease of operation of a lagoon-based facility.

Prefabricated stations address wastewater challenges for remote communities

By Mehran Masoudi

Wastewater management in remote communities often comes with a variety of challenges, beginning with a lack of infrastructure and sufficient resources. The costs associated with installing and maintaining infrastructure traditionally used for wastewater management are often prohibitive for such communities. Inadequate maintenance inevitably leads to decreased efficiency, increases operating costs, but more importantly could result in significant environmental impacts, if left unmanaged.

Limited resources can also inhibit a plant’s ability to ensure compliance with the strict regulations meant to safeguard public health and the environment. Changes in demand, particularly for areas with rapid population growth, can lead to capacity issues and a need to upgrade or expand treatment facilities. All too often unreliable electricity supply further complicates the situation.

Aging infrastructure introduces its own additional issues, including inflow and infiltration (I&I), which is the unintentional entry of water into a sewer system from sources other than the intended wastewater flows.

As lift stations and their associated infrastructure age, they can become prone to leaks, cracks, and other types of damage that can allow rainwater or groundwater to enter the system. I&I can overwhelm the capacity of the sewer system and lead to overflows or spills. Many wastewater facilities are decades old and have outlived their useful life. This leads to increased maintenance costs, reduced efficiency, and potential health risks for people who live or work near them. Additionally, many of these systems are not equipped with modern water treatment technologies, making it difficult to meet stricter regulatory requirements.

DECENTRALIZED TREATMENT SYSTEMS

One approach that has become increasingly popular for managing wastewater in smaller communities is a decentralized treatment system (DTS). This involves the use of smaller-scale technologies, such as septic tanks, constructed wetlands, or aerobic and anaerobic treatment systems.

These technologies are tailored to the specific needs of the community and are simpler, easier to maintain, more flexible and lower in cost than larger-scale centralized treatment plants. They allow communities to treat wastewater independently without relying on external resources or sending untreated wastewater elsewhere.

Another benefit in using a decentralized treatment approach, is that the pumping needs are considerably reduced, as the need to pump wastewater to a distant plant is no longer required.

Using several intermediate and

decentralized pump stations instead of a centralized solution, helps to avoid deep excavation of the gravity sewer mains. Classic centralized systems for small communities spread over a large area often mean deep gravity mains, which can result in construction and safety problems. Deep excavation, laying of underground pipes and wet well pump station excavation quickly becomes an expensive project.

WASTEWATER PUMP STATIONS

Wastewater pump stations designed for small communities are the heart and arguably the most important component of a DTS. They include a series of pumps (usually one in operation and one standby), valves, piping and instrumentation. Pump stations serve to collect, store and move wastewater from one location to another.

They can be assembled on-site by pouring concrete and then adding each required component, or can be pre-assembled (pre-fabricated) before arriving on-site, which significantly reduces project complexity, cost, and the time required for installation.

Pre-fabricated stations arrive on-site with all components preassembled in a fibre-reinforced plastic (FRP) underground tank, completely sealed to the surrounding environment.

The wet well is designed based on the actual project location’s environmental parameters to ensure long-term, efficient and trouble-free operation. The FRP wet well is designed to eliminate solids accumulation with a smooth internal finish and clog preventing features.

The vendor manages everything, including all aspects of design (mechanical, electrical, civil, controls and structural engineering,) manufacture, assembly, installation and even aftermarket support. Such stations can manage a wide range of flowrates and capacities to

meet the average daily flows as well as peak demand.

For ease of operation, prefabricated lift station systems come with a local control panel that contains all the necessary operational parameters and a digital display. This allows operators to view system performance and make changes as needed. The control panel is typically preprogrammed and tested at the shop by simulating a broad range of require-

ments for different conditions.

Once on site, installation and startup of these smart control systems is quick and easy. These systems can be connected to a SCADA (supervisory control and data acquisition) system for 24/7 monitoring and control of the water content from anywhere. Operators can easily monitor, diagnose and adjust the system remotely from a mobile phone or SCADA.

Designed and manufactured locally in Canada, KSB’s prefabricated wastewater pump stations are compliant with all local health and safety regulations and standards.

Ontario Onsite Wastewater Association helps regulators and property owners in rural municipalities

By Jenn McCallum

The Ontario Onsite Wastewater Association (OOWA) is a not-for-profit, membership-based, industry association dedicated to promoting the benefit and value of onsite and decentralized wastewater management as a permanent, cost-effective solution for communities and citizens.

With over 600 members, we represent the spectrum of roles within this sector: manufacturers, precasters, distributors, suppliers, engineers, consultants, designers, regulators, installers, haulers, private inspectors, and researchers. The onsite and decentralized industry is a means to preserve resources and OOWA advocates for sound policies through education, engagement, and guidance.

OOWA continues to sustain relationships with the Ontario Ministry of Municipal Affairs and Housing (MMAH) and Ministry of Environment, Conservation and Parks (MECP) on behalf of our members and leverages these connections to promote the need for continuing education, consistent regulations and to strengthen the influence of the association.

GUIDANCE DOCUMENTS

OOWA’s onsite technical committee meets regularly to create and refine our series of guidance documents that are available on our website (oowa.org). There are currently nine of them, including Inspection of Onsite Systems, How to Decommission an Existing Onsite Sewage System, and Flow Balancing At the end of 2022, we released a guidance document entitled, Frequently Asked Questions (FAQ) on Key Inspection Points, and we have more planned for this coming year.

The FAQ document has been prepared to provide some information and clarification of the intent of the Ontario Building Code regarding some common questions that have been brought forward by our members. These questions are primarily from building inspectors and relate to key inspection points during the installation process, such as: How many inspections should be completed? What inspection details should be recorded? Should homeowner installed systems be treated differently?

OOWA MEMBERSHIP

Since its establishment in 1999, the OOWA has provided access to a large network of onsite wastewater professionals. Our members are at the front lines of rural development, supporting onsite systems as sustainable, affordable, and permanent wastewater servicing options. We promote training courses being offered by our education partners, including the Ontario Rural Wastewater Centre and the Ontario Building Officials Association. With in-person events and training returning, our 2023 cal-

endar is filling up with various offerings of the Ontario Building Code Part 8 Exam Prep course and General Legal Process and Powers and Duties course. Recently, OOWA has partnered with the Ontario Rural Wastewater Centre to bring new training opportunities to our members, including the one-day Introduction to Design of Onsite Sewage Systems and Advanced Design of Onsite Sewage Systems courses.

Our annual convention and exposition will take place on March 26 to 28, 2023, in Huntsville, Ontario. Typically, over 350 Ontario industry professionals gather at this event to connect and learn about best practices, regulatory updates, and new innovations.

PART 8 PANEL DISCUSSIONS

During the pandemic, OOWA began providing virtual, members-only, Part 8 panel discussions three or four times per year. Each discussion features a regulator professional, engineer or designer, and installer to discuss relevant topics pertaining to Part 8 of the Ontario Building Code. Our most recent panel discussion was held on November 2, 2022, and covered defining structures to determine clearances and the effect of heavy soils (T>50 min/cm), and highly permeable soils (T<1 min/cm), on design and installation. Although we can now move back to in-person discussions, our virtual panels have been so successful that we plan to continue delivering this benefit to our members on a regular basis.

HOMEOWNER RESOURCES

OOWA has developed several resources that are directed to rural property owners, encouraging them to regularly maintain their onsite sewage sys-

Preserving a town’s natural resources with an all-terrain sewer

By Joseph Harmes

In 1870, the first settlers christened tiny Confluence, Pennsylvania, for its location at the junction of the Casselman River and Laurel Hill Creek with the Youghiogheny River. But, like many hamlets scattered throughout the region, it has struggled to maintain a population of more than 1,000, or to attract industry of any real size.

In less than a generation, however, Confluence has transitioned from stagnation and a fading industry that could have ravaged scenic hills, old-growth forests, sparkling creeks and the remote habitats of endangered species into a robust economic juncture of prized recreational venues for hiking, fishing, kayaking, rock climbing and boating. It is also financially buttressed during the winter by four area ski resorts and miles of cross-country paths.

ECONOMIC FUTURE IN PERIL

But, as this burgeoning economy was being shaped, its aging and failing combined sewer system (CSS) threatened its future. In 2014, Confluence’s outfalls became the focus of a lawsuit filed by Pennsylvania’s Future, an out-of-town citizen group. It alleged that the Confluence Borough Municipal Authority, as operator of the publicly-owned treatment works, violated the Federal Water Pollution Control Act and the Pennsylvania Clean Streams Law.

Within a month the group offered to drop the case under a consent decree mandating “a plan to engineer and construct a new pressure sewage collection and conveyance system for the borough, to replace the existing gravity flow network in order to eliminate SSOs (sanitary sewer overflows) and maintain compliance with effluent limitations.”

The existing gravity sewer (about 7,600 m of pipe of which 4,850 m consisted of pre-1970 terra cotta pipe, rang-

ing from 200 mm – 350 mm in diameter) would be left in place to become a separate stormwater collection and conveyance system.

Five years prior to the lawsuit, Confluence had contemplated, designed and planned a sewer rehab project, calling for separating the combined sewer into a dedicated gravity sanitary sewer line and another gravity sewer for stormwater.

Septic systems were not an option as a “Sewage Facilities Plan” prepared in 2010 found approximately “80 percent of the borough’s land unsuitable for any type of on-lot disposal systems”, largely due to steep slopes and flooding. Only five percent of the land in the area contains soils suitable for septic disposal systems, the report added. “Approximately 10 percent of the land contains soils that would be moderately suitable for septic disposal systems.”

ABANDONING GRAVITY

“My first task when taking over the Confluence project (around 2014) was to finish the plan and proceed with construction,” says John Larimer, the borough’s engineer, now with CME Management. “I disagreed with the plan and proposed the pressure sewer replacement for several reasons. Gravity sewers cannot and will not work in an area surrounded by water. Pressure sewers can and will work.”

“We were contacted by the engineering firm in 2014 to explore part of the project as a pressure sewer,” says Benjamin Dorsch who was with Trombold Equipment Company at the time. “The whole pressure sewer design started as a feasibility exercise based on Google Earth. In less than two weeks we had an entire layout with calculations back in the engineer’s hands for the entire system. The Pennsylvania Department of Environmental Protection approved it to replace the entire gravity sewer system and this was written into the Consent Decree.”

Larimer says he was attracted to the All-Terrain Sewer (ATS) manufactured by Environment One Corporation (E/ One), after reading case studies about its gravity to pressure sewer conversion projects.

“Leaving the existing gravity sewers in place solved the stormwater problem,” Larimer adds. “We separated the sewer out of the stormwater rather than take the stormwater out of the sewer. Gravity sewers would have been in excess of 6 m in depth. We eliminated the lift station at the treatment plant, which was a maintenance nightmare, especially during rain events.”

The E/One grinder pump station begins with a tank about the size of a tall refrigerator that is buried in the ground, its lid easily camouflaged with

minor landscaping. Components include a 1-hp, semi-positive displacement pump, which can send wastewater through small-diameter, inflow-and-infiltration-free pressurized pipe for a distance of more than five kilometres, or vertically up 55 m to a force main or treatment plant.

A WATER-TIGHT SOLUTION

A critical, persistent problem plaguing Confluence’s CSS was inflow and infiltration (I&I) which can create detrimental environmental and economic effects on the overall operation of the wastewater collection and treatment station. The borough identified 101 sources of I&I, including downspout drains, catch basins, service laterals, manhole seals, and basement drains.

An ATS is constructed of PVC pipe with solvent-welded joints and leak tested to the same standards used for potable water supply piping networks. Water-tight and virtually leakfree, it is not subject to infiltration from groundwater or from surface stormwater entering through leaking pipe joints and manholes. The reduced I&I can result in smaller treatment system sizing, thereby saving capital costs. In northern climates, the pipe is buried beneath the frost line. Over 100,000 ATS units have operated for decades throughout the Nordic countries.

A CONVERGENCE OF SAVINGS

The Confluence Borough Municipal Authority Wastewater Treatment Plant was constructed in 1975 with a design capacity of 518,000 litres per day, with a peak daily flow rate of 1.3 million litres per day. Daily flow periodically exceeded design capacity during wet weather periods because stormwater and stream flow infiltrated the borough’s collection and conveyance system.

The ATS significantly reduced the sewer rehab budget and improved the WWTP’s efficiency as it eliminated the need for a 7.6 m deep confined space raw sewage pump station at its headworks. Instead, individual grinder pumps will convey sewage to the treatment plant.

When the ATS entered the discussion as an alternative solution, Confluence compared the costs and scope of its two alternatives. “Preliminary cost estimates indicated the pressure sewer system installation to be comparable or less than the cost of gravity sewer replacement. The gravity sewer would address only portions of the system and the pressure sewer would address the entire system,” said CME’s Uniform Environmental Report.

The plan to upgrade the existing gravity system and WWTP carried a preliminary price of almost US$6 million. The estimated cost in 2015 of installing the ATS and abandoning the existing system in place for stormwater use was found to be US$800,000 cheaper.

In 2019, just before the project broke ground, the Pennsylvania Infrastructure Investment Authority put the final tab at US$9 million dollars to connect all 422 households (homes and multi-residential) in the borough, with a service area of approximately 4.35 km2

ATS GOES ONLINE

The project was completed in 2020. The ATS incorporates 373 Simplex (one pump) station, four Duplex stations (two pumps inside the same housing) and one Triplex station to serve mobile home parks. Three other Triplex units were allocated for senior citizen apartment complexes. A portion of the budget also funded gravity stormwater pipe repairs and WWTP upgrades.

The majority of new pipelines, including three river crossings, were constructed in road rights-of-way, requiring only minimal lane closures or detours because of the use of horizontal direct drilling. No adverse impacts on agriculture, state parks, forests or trails were reported and the area’s historic Native American cultural landmarks were preserved.

“Simply put, we basically ran the old gravity sewer system while building the ATS,” says Larimer. “Once it was intact, customers were switched from the old to the new while both systems were maintained. The old system was abandoned in place once everyone was switched to the new system.”

3M exits PFAS business amid flurry of contamination lawsuits

By ES&E Staff

After some six decades and more than 3,000 lawsuits over claims of ground and water contamination, 3M has announced the end of production for per- and polyfluoroalkyl substances (PFAS), or what have come to be known as “forever chemicals”.

Manufacturing of PFAS will cease by 2025, marking the end of a billion-dollar industry for Minnesota-based 3M, which manufactured chemicals for a long list of products, including nonstick cookware, fire retardants, as well as stain and water repellents, and medical technologies.

3M Chairman and CEO Mike Roman described the end of PFAS production in an announcement at the end of December, noting that it was “a moment that demands the kind of innovation 3M is known for,” while still acknowledging that PFAS “can be safely made and used.”

3M is not alone as a target for PFAS litigation, and its departure from the industry will not relieve it of liability for historical uses. The company has less current litigation underway than E.I. du Pont de Nemours and Co., Chemours, and Kidde plc Inc.

A California groundwater agency, in one state lawsuit, alleges that 3M “knowingly” polluted groundwater, as it had learned decades ago that PFAS essentially do not degrade.

PFAS, which include a group of more than 4,700 human-made substances, are known as “forever chemicals,” given the slow rate at which they break down in the environment. They are also considered known carcinogens.

3M makes some 60,000 products under several brands, including adhesives, abrasives, laminates, passive fire protection, personal protective equipment, window films, and paint protection films.

Last year, Canada released a proposed new Prohibition of Certain Toxic Sub-

stances Regulation, 2022, which would replace the 2016 Toxic Substances Regulation. While PFAS are still allowed for import, the proposed legislation could eliminate the various exemptions allowing PFAS substances in Canada under certain circumstances.

The comment period for the proposal ended in summer 2022. The legislation refers specifically to perfluorooctane sulfonate, its salts and its precursors, known as PFOS, as well as perfluorooctanoic acid, its salts and its precursors, known as PFOA.

Environment and Climate Change Canada is still working on a draft document that intends to paint a wider picture about the state of PFAS and related chemicals in Canada, although the chemicals are not manufactured here.

Currently in Canada, the University of Waterloo is leading an interdisciplinary research team that hopes to unlock key information that will inform Canadian water systems about potential PFAS

contaminants.

Additionally, a Vancouver firm is testing the use of electrochemical oxidation to destroy PFAS.

Exemplifying the potential harm of PFAS may be its presence in firefighting foams, as seen in North Bay, Ontario.

SHARC deal aims to triple wastewater energy transfer for Vancouver’s False Creek

By ES&E Staff

British Columbia-based SHARC International Systems Inc. says its new deal with the City of Vancouver will create the largest project in North America that recovers thermal energy from wastewater before it enters the sewer.

Recovered energy from Vancouver’s False Creek Neighbourhood Energy Utility (NEU) started flowing in 2010 to power the Athlete’s Village, as part of the 2010 Winter Olympic Games. Under the new SHARC deal, the expansion is expected to increase the capacity of the NEU’s current 3.2 megawatts (MW) of wastewater energy transfer to 9.8 MW.

The expansion will also create an additional carbon emission reduction

of some 4,400 tonnes annually when the project is completed later this year.

“This project is a crucial step forward to ensure the NEU can continue to provide reliable, cost-effective, low carbon energy to the growing network of connected buildings,” announced City of Vancouver NEU Manager Derek Pope, in a statement.

With the wastewater energy transfer process, all of the heat (approximately 20ºC) from the hot water used for showers, dishes, and laundry can be recovered, explains Lynn Mueller, CEO of SHARC Energy. Its equipment uses the recycled heat energy to pre-heat the water fed to a building’s hot water tank or boiler.

Since False Creek began, its energy utility has expanded to serve over 600,000 square metres of residential, commercial

and institutional space, including Science World and Emily Carr University. It will now continue to expand to serve nearly two million square metres of new development.

SHARC Energy began working with Vancouver in 2017 when it retrofitted two systems for sewage screening into the False Creek NEU as a pilot. SHARC entered a lease on these units with Vancouver, and they are now being replaced with the latest expansion of the system.

SHARC Energy also has two pilot neighbourhoods in Ottawa where it is utilizing its PIRANHA system for wastewater heat recovery.

New reality show navigates sewer infrastructure with divers

By ES&E Staff

Anew series from the Discovery Channel takes viewers on a journey through sewer systems in several major U.S. cities as they tackle clogs and broken pipes.

Highlighting the challenges of the dirty job, as well as the age of the deteriorating infrastructure, “Sewer Divers” goes to great lengths to show how workers keep clean water running and toilets flushing.

While the show looks to stay south of

the border, Canada has utilized sewer divers before. According to Metro Vancouver, some sewer repairs that would have taken days to complete can be made in just hours using divers.

In the series premiere of Sewer Divers, one of the divers shows off his $3,000 rubber suit fitted with a 13.6 kg helmet to keep him safe from noxious chemi-

cals flowing in all directions.

The first episode looks inside the Emergency Sewer Division of Mount Vernon, NY, which tries to drain sewage that flooded a resident’s basement.

In the last part of the series’ premiere, the Northeast Ohio Sewer District team attempts to clean a massive pile of hardened sludge dubbed the “Mega Clog” from the floor of the sewers.

Rick Simon, who owns a commercial diving company is featured in the pilot episode. He says about one quarter of his workload is devoted to repairing sewer systems.

The episode also features New Jersey-based commercial diver Don Gann, aka “Dirty Water Don.” He says he has had numerous close calls during his work in sewers.

“I have been pinned, when things have fallen on top of me. I couldn’t get out on my own, so another diver had to come in to get me. I have also been buried digging a hole for an underwater cable. The hole collapsed on top of me, so every time I took a breath, the mud constricted me more,” he explained.

Gann goes on to describe the hazards of disease and contamination from entering sewage-filled pipes, not to mention the broken glass and hypodermic needles.

In upcoming episodes, the divers will search for a clog in a wastewater treatment plant’s outflow pipe, and try to fix a huge sewer break threatening people’s basements in Mount Vernon.

Ontario puts brakes on Upper York sewage plan after eight-year wait

The Ontario government has nixed York Region’s plan for its long-proposed Upper York Sewage Solution, and instead approved expedited improvements to the existing York-Durham Sewage System network connected to the Duffin Creek Water Pollution Control Plant.

Co-owned and operated by York and Durham Regions, the Duffin Creek facility operates at approximately 50% capacity, and the proposal would add an additional 12% to current flow levels, “meaning it has the capacity to ensure every litre of water the plant receives gets high quality treatment,” the province announced.

The plant can process some 630 million litres per day, and would not need to be expanded for some 20 years. It has already received investments of more than $850 million over the last 25 years.

Since 2014, the three municipalities have worked to find a wastewater solution that can handle future growth in those communities. But, the option of sending wastewater from Newmarket, Aurora and East Gwillimbury to a new treatment plant that discharges into Lake Simcoe has drawn criticism from Indigenous communities and environmentalists worried about the lake’s health.

The new decision, which came eight years after the project was introduced, but immediately after Ontario’s municipal election, is based on recommendations made by the York Region Wastewater Advisory Panel. It was formed in 2021, after more than $100 million was already spent on the environmental assessment and design of the Upper York Sewage Solution.

In its report, the panel found that the Upper York plan would create higher greenhouse gas levels and phosphorus

loading limits than the Duffin Creek expansion. Additionally, the Upper York plan would not fully align with the Lake Simcoe Protection Act and Lake Simcoe Protection Plan,

“Our government is proposing a solution that ensures the most robust wastewater treatment as these communities continue to grow,” announced David Piccini, Ontario Minister of the Environment, Conservation and Parks, in a statement. “The Duffin Creek treatment facility is one of the best performing wastewater facilities in the province that ensures the protection, enjoyment and welfare of Lake Ontario, shoreline communities and nearshore areas,” he added.

The panel was informed that growth planned to 2051 would add approximately 9,000 acres to Durham’s urban boundary, and approximately 575,000 people to the Region’s eight municipalities.

A sonic alternative to controlling harmful algal blooms

By George Hutchinson

The threat of cyanobacteria has been increasing for years and with the rise in global temperatures it is becoming more of a problem. It is destructive and harms aquatic ecosystems, people, animals, drinking water supplies, the economy, and outdoor activities.

In freshwater lakes, ponds and reservoirs, harmful algae blooms (HABs) are usually the result of cyanobacteria, most commonly known as blue-green algae. Most of these types of algae are naturally heavier than water, but have built-in buoyancy that allows them to come to the surface for sunlight.

This buoyancy keeps them at the same density as water, so small changes allow them to sink to the bottom for nutrients at night and also come to the surface early in the day for sunlight. As they cover the surface, they shade out

the sunlight for other types of algae and plants below, causing them to die.

This dying biomass is consumed by bacteria, causing a host of other issues such as depleted oxygen levels which are bad for fish, as well as producing foul smells. As the biomass dies, it releases nutrients such as phosphate that in turn feeds the cyanobacteria bloom, making it grow even faster.

Cyanobacteria are much older as a species and share many of the same attributes as algae, such as the ability to photosynthesize.

As problems associated with algal blooms increase across tens of thousands of lakes, reservoirs, ponds, and managed water repositories, cities and utilities are taking a number of measures to help stop the issue. Historically, chemicals were used. However, due to their cost and potential for environmen-

tal harm, they are not a good solution for many environments.

Ironically, the overuse of algaecides can also contribute to harmful blooms of cyanobacteria. This stems from the copper sulphate in the algaecides that can cause death to not only unwanted algae, but also to beneficial bacteria that are necessary to help remove excess nutrients that escalate the growth of algal blooms. The remaining bacteria, unaffected by the copper sulphate, are mostly anaerobic, including actinomyces, a group responsible for strong odours in these environments.

Overuse of algaecides can also eliminate useful, beneficial bacteria in the sediment that can result in less phosphate being consumed. This is because remaining bacteria unaffected by the copper sulphate are mostly anaerobic and they eventually cause the algae problem to spi-

California’s groundwater warning should resonate in Saskatchewan, scientist warns

By ES&E Staff

The depletion of groundwater should be a wake-up call for Canada, where more than half of the population relies on groundwater for drinking, and for Saskatchewan, which is striving to double its food production capacity, a University of Saskatchewan scientist warns.

Dr. Jay Famiglietti, professor emeritus in hydrology at USask, and former executive director of USask’s Global Institute for Water Security, has pioneered methods to observe changes in global groundwater stores over the past two decades using a specialized NASA satellite.

Famiglietti’s work has made a key discovery about the aquifers that supply California’s Central Valley region. He believes that the groundwater depletion rate has accelerated to a point where the resource could disappear over the next several decades.

“If that water disappears, so does food production. That means less produce, higher prices, shortages, and other shocks to food systems,” states Famiglietti. “All around the world, we have been kicking the can down the road for a long time on effectively managing groundwater. Now we are at the end of the road, and it’s a dead end.”

California’s Central Valley grows most of the produce consumed across North America. To do that it relies heavily on aquifers.

Famiglietti’s team analyzed nearly two decades of data collected by NASA’s Gravity Recovery and Climate Experiment (GRACE) satellite and the GRACE Follow-On satellite. Their research shows groundwater losses during 20192021—the driest three-year period in California’s history—were 31% faster than in two previous drought periods of 2006-2011, and 2011 to 2017. This rate is also five times greater than the longterm average rate of depletion since 1962.

Accompanying the disappearance of groundwater, there is ecological damage

as wetlands are drained, and as streams run dry.

In Canada, Famiglietti notes that the South Saskatchewan River water is close to being over-allocated already, as is the

water in many of Canada’s rivers, so care must be taken to avoid Saskatchewan becoming another California or Colorado River Basin.

“We have to think about how much groundwater we need for sustainable food production, and then to manage to balance that with changing surface water availability so that we can do it for centuries, not just for a few decades. Currently we are okay, but if we want to increase food production and we want to be doing it on an annual, sustainable basis, that means irrigation and that means having continuous access to water. To me that means groundwater.”

ral out of control by continuing to recycle phosphates back into the water column.

This then fuels cyanobacteria, creating complex hydrocarbons that are poisonous to many organisms, including animals and humans.

HABs can bloom when extremely small amounts of phosphate pollution get into a waterbody. Phosphates typically come from farm fertilizer runoff, over fertilization of lawns, phosphate-based cleaning soaps and surfactants.

Algae requires sunlight and nutrients, such as phosphorus and nitrogen, to proliferate. While spring and summer see widespread growth of algae, a large increase of blooms can also occur after summer has warmed the sediment levels in a water body. The sediment holds much of the undigested organic food laden with phosphates that has settled since the last winter season, such as leaves, dead plants, etc.

These undigested phosphates typically lie in the bottom area of a body of water, where oxygen levels are low. It is

The Pulsar 4000 generates more than 2,000 frequencies, allowing it to work against most forms of algae.

also in these areas that the coldest conditions exist, lagging behind air and surface temperatures as summer warming continues.

Typically, in the northern hemisphere, the bottom areas generally reach a temperature that is high enough for anaerobic bacteria to become very active from late June to the middle of July, depend-

ing on the latitude and the number of sun hours per day.

Once this temperature is reached, the anaerobes become very busy consuming the muck and expelling a large volume of phosphates that can generate HABs.

A HOLISTIC APPROACH

Over the past decade, technologies have evolved to better manage cyanobacteria and other algae. These solutions are sustainable, environmentally friendly solutions that don’t involve chemicals.

Ultrasonic mitigation is increasingly being turned to as an effective and lowcost solution for wastewater repositories, cities and utilities. This solution is safe and, in many cases, returns water ecosystems to their natural state. The wide frequency range of ultrasound has proven very effective in treating most algae, while causing no harm to zooplankton or fish.

Not all ultrasonic waves are the same. At the extreme end, there are high-powered ultrasound waves that can cause the formation of cavitation bubbles that inwardly implode, creating intense heat and pressure. This is deadly not only to algae, but many other organisms in their path.

Then, there is ultrasound at the frequency range and sound volume that has just enough energy to cause algae cells to reach critical resonance and be damaged to a point where they will be adversely affected, yet not enough to cause damage to other species.

Cyanobacteria regulate their buoyancy with gas vesicles, enabling them to sink to the bottom of water bodies and obtain an abundant supply of phosphates there. This also presents an efficient way to control HABs as ultrasound can be used to break the gas vesicles of cyanobacteria so that they can no longer float back to the surface for sunlight. This lack of sunlight then ultimately causes cyanobacteria to die.

Addressing nutrient levels is an important process in the short- and long-term reduction of HABs. This means regular testing of all influents and sections of the water body to determine the source of nutrient pollution, after which remedies can be applied.

While each body of water is unique, with its own influents and ecosystem, it

is becoming increasingly evident that a holistic approach, involving both nutrient and algae control, can be very effective at providing a rapid, long-term solution to the problem.

In addition to reducing nutrient levels, it is also important to consider aeration systems, good green algae, and ultrasonic mitigation.

Next-generation ultrasonic algae mitigation systems can be extremely effective. Ultrasonic solutions create a first line of defense, knocking down algae blooms before they become harmful. The devices can be deployed in multiples to create control areas of concentric circles that work together to cover large areas. These systems have been shown to be capable of up to 50 hectares of coverage per device for cyanobacteria.

The latest ultrasonic systems transmit more than 2,000 frequencies to ensure that effective resonance is applied at the frequency bandwidths that have been shown to work against algae, diatoms and cyanobacteria. These frequencies

cause internal cell structural damage to these algal types.

Some frequencies break cyanobacteria gas vesicles, causing loss of buoyancy. Others cause tears in green algae and diatom internal cell walls, causing a loss of internal pressure and bacterial defense.

The wide frequency range of ultrasound proves very effective in treating most algae, while causing no harm to zooplankton or fish. In addition to the frequency output of an ultrasonic anti-algae system, the mechanical design of most advanced systems incorporates algae repellent surfaces. This reduces the chance of biofouling, which could otherwise harm the effectiveness of these systems.

Today’s state-of-the-art autonomous systems do not require land-based power and are suited for large bodies of water, including ponds, reservoirs and lakes. The more advanced ultrasonic solutions include IoT (the Internet of Things) and telemetry components, as well as solar power to enable all onboard systems to provide years of continuous use.

It has been estimated that approximately 95% of the 70,000 species and two million sub-species of algae are affected by ultrasound. Most often, this technology can preempt an algae bloom and keep it from spreading further.

As adept as these ultrasonic waves can be in dispatching algae and cyanobacteria, they are also fairly safe for non-algal beings. Unlike chemicals or other treatment methods, ultrasound, properly done, is not harmful for the environment or fish, birds, humans and beneficial aquatic plants.

Although ultrasound is meant to be an alternative to the use of chemicals, such as copper sulphate, it is most effective when used as a treatment option, supplemented by a selection of other remedies to achieve 100% coverage.

Precast concrete flood box saves BC town from floods

By Joel Thomson

In 2020, the District of Kent in Agassiz, British Columbia engaged Urban Systems to design the replacement of the Agassiz flood gate. Agassiz is a small-town northeast of Chilliwack and about a 90-minute drive from Vancouver.

The flood gate is located on Dyke Road west of Highway 9 (Agassiz-Rosedale Highway) and south of Whelpton Road. Adjacent to Dyke Road on the north end (upstream) of the existing drainage culvert, is the Agassiz slough. This slough sees most of the stormwater runoff from the Town of Agassiz.

The existing culvert was a 1.5 m diameter corrugated steel pipe (CSP) with a top-mounted flap gate. This structure was roughly 50 years old and provided flood drainage away from the Town of Agassiz by transporting slough water through Dyke Road.

There were several issues with the existing structure that made it less than ideal and a risk to the community. The 1.5 m diameter CSP was significantly undersized for a 1 in 100-year flood event, the age of the structure made it at a high risk of failure, and the original structure design, with a top-mounted flap gate, did not permit adequate fish passage. Replacement of the structure was well justified.

The Urban Systems engineering team explored the various options for this site and ultimately chose to use a precast concrete box structure. This choice allowed for mounting the heavy and large steel slide flood gate. The precast concrete option was also a good choice for incorporating integrated fish baffles and providing a design life of over 100 years in a constantly submerged condition. At this point, the Langley Concrete Group was contacted.

A 3.66 m wide by 1.83 m tall precast concrete box was determined to provide a hydraulic design flow capable of withstanding a 1 in 100-year flood event.

300 mm tall by 254 mm long fish baffles were cast integral to the precast concrete box for the entire width of the opening. One baffle was required at each of the precast sections on the downstream side, with the first upstream box section requiring one at both the upstream and downstream ends.

The upstream and downstream aprons were also precast concrete and required the installation of timber piles below. These piles would counteract the potential settlement of the aprons and ensure proper vertical alignment with the channel for the duration of the structure’s life.

There were four piles for each apron. The upstream end features a full width and height trash grate. The downstream end has a full width and height vertical slide gate. It is mounted directly to the precast concrete by a stainless-steel wall thimble frame embedded into the downstream precast section.

Langley Concrete Group completed the

structural design of the precast concrete box and the design for the integrated fish baffles, trash grate, and vertical gate attachment. In addition to this, there was a significant amount of engineering required for the precast end treatments, consisting of head-walls, wing-walls and aprons.

The size of the end treatments was a challenge both for manufacturing, transport and installation. The final design utilized modular sections, for ease of transport, with in-cast weld plates, for on-site assembly.

After the project was tendered, the precast concrete sections were manufactured. All the precast was complete before the contractor began work on site. The precast structure not only provided the contractor with the potential for an accelerated construction schedule, but also mitigated the risk of delays due to manufacturing, weather, and/or labour shortages.

Best practices for pipe repair and replacement programs

By Ken Alessi

The very nature of a pipe burst is that it is unexpected. Crews jump into action and solve the problem as quickly as possible to mitigate damage. Like any emergency, the speed of resolution is often more important than the cost. Utilities are prepared to pull personnel off other jobs, rent expensive equipment, pay high couriers fees, and so on. In contrast, replacement of aging infrastructure often comes with the gift of time that is used to hire experts to do condition assessment, source the optimal solution and prioritize critical needs first.

While you may not know exactly when and where the next pipe will burst, planning for breaks is possible, and the effort expended on this is a direct benefit to optimizing replacement projects.

INVENTORY MANAGEMENT

With global supply under strain, never has it been more important to have the inventory needed on hand. It is impossible to have every item needed, and the cost to purchase expensive parts for a very unlikely event, is more a luxury than a need. Combining infrastructure knowledge, such as pipe type, size and age, with the experience of work crews is critical to maintaining an affordable and high turnover inventory.

Carefully look at the demand for repair products and when they are used most frequently. Look at orders over the course of the last three or four years and try to identify trends. See if there are periods when the demand for certain clamps or couplings is high, and other periods when it is low. This will help determine which products should be in high supply and which ones can be lower.

There are also products that are designed to fit a wide range of pipe types and diameters. Product design can go a long way to broadening the versatility and scope of repair. For example, there are several coupling products, such as the HYMAX® Versa, that have the versatility to either join or repair pipes, offering a high degree of flexibility to make repairs as needed. These kinds of clamps and couplings can take the place of up to three traditional products, on the shelf or in the truck.

Weather can also play a key role in determining which repair supplies will be in high demand and how fast you can obtain them. Repairs are often required when the ground shifts during the spring thaw, and at other times of the year when the weather is extreme. Keep in mind deliveries can be harder to fill when severe weather hits parts of the country.

USING THE RIGHT TOOLS

When a repair is not working, it is often because the wrong practices are being used to do the job. For example, thrust

blocks are probably the most common way to restrain pipe. Engineers go to great lengths to design the right thrust block based upon the needs of the project. Bags of concrete mix with holes punched in them and a bucket of water poured on top is not a thrust block, nor is a 4x4 post. Make-shift restraints inevitably fail and then the whole expense of the repair needs to be repeated. However, in many circumstances, mechanically restrained products, such as the HYMAX Grip that uses a mechanism to grip the pipes, can be used to restrain the pipe, saving repair time and cost of engineered thrust blocks.

When connecting pipe, use a coupling, not a clamp. Repair clamps are designed to repair holes or ring breaks. They are not designed to couple pipe, since they offer no deflection or restraint capacity, which could result in a failure.

Choosing the right sized repair product is also important to making good repairs, and one can only know for sure the size of the pipe with an OD tape. It is not uncommon for people to devise their own methods for measuring the outside diame-

ter of the pipe and getting it wrong. This is the first thing to double check when a new clamp install is leaking. Is this the right sized clamp? Some product lines have wide OD ranges meaning that the products will work on a wider variety of ODs, so there is some margin for error.

As a rule of thumb, repair teams should have the following items on hand:

• OD tape

• Torque wrench

• Deep socket set

• Adjustable wrenches

• Pipe scraper

• Cordless impact wrench

• Safety gear (hard hat, protective eyewear, safety vest, protective shoes, etc.)

• Pipe saw/cutter

• Trench box

TRAINING

Keeping up to date on new solutions and even brushing up on skills that are used every day is important. It is not uncommon for crews to pick up bad habits or use old methods that take

longer to get the job done. Bad habits can affect worker safety and tend to get passed on to new recruits.

Both the American Water Works Association and the National Rural Water Association host a series of educational workshops with different manufacturers, many of which are accredited. As well, many repair product manufacturers offer courses. While it is ideal to get the hands-on experience, due to the global pandemic, more manufacturers are doing online training, making it more accessible than ever before.

APPROVED CONTRACTORS VS. IN-HOUSE

If budgets allow the hiring of expert repair contractors, this is an excellent option as it alleviates having to own the expensive equipment and keeping up to date on specialized training. Not having the cost of these highly skilled workers on a payroll when nothing is happening, can also justify the higher cost when you do need them. Ensure that an annual

review of approved contractors is done, in order to stay up to date. Also, determine who is available and what new equipment they may have acquired.

The downside of contractors is that they are not always available and when big weather events happen, they are in top demand. This means availability and pricing can be an issue. If most of the repair work is done by contractors, utilities will still want to ensure their staff are up to date on training in case they are the only option during a severe crisis.

With this outsourcing approach, engineers often decide when and how to do the repairs, but utility managers should be part of the planning process. Once a piping system is completed, it is in their hands to ensure the system works properly.

In-house crews have their advantages. They are most familiar with the system and usually have a broader understanding of all the factors at play that lead to the repair. This can affect the long-term outcome. In-house crews tend to have a continued overleaf…

holistic understanding of the system, which is better for inventory management and long-term planning for pipe replacement programs. On-site crews may fix a repair, and decide that the pipe needs to be prioritized in the replacement program, given its condition.

As there are advantages to both, a hybrid approach can work very well. In some cases, it can be pure necessity if a utility does not have the large construction equipment that is needed for the repair. So regardless of the approach, it is important to have good relationships with contractors before they are needed in an emergency.

CHOOSING THE RIGHT MATERIALS MATTERS

Not all materials are made equal, and the price will factor into choosing one material over another. If purchasers take into consideration the cost of repairing or replacing the new pipe, going with the higher quality product pays for itself in the long run.

Couplings and clamps that are easy to install can make repair jobs more efficient, save time and help eliminate installation errors. There are a variety of repair couplings that are quick and easy to install. For example, the HYMAX 2 coupling has top-facing bolts that are simple to tighten and drastically cut installers’ repair time. Products that don’t have to be disassembled can also make a big difference in making a quick installation.

OPTIMIZING THE DISTRIBUTION SYSTEM

There are many factors and indicators leading up to a pipe burst. While these best practices will help streamline the ability to react and rectify an immediate problem, optimizing the distribution system is the foundational best practice for pipe repair and replacement.

Monitoring and managing water pressure in a system will go a long way to preventing pipe bursts and investing in this technology will reduce your number of pipe bursts. Monitor-

ing the progression and severity of leaks will also help crews to prioritize repairs before a burst is imminent. Full time leak monitoring can be as easy as adding a leak detection node to an existing hydrant that will transmit data and inform crews of imminent concerns.

All utilities are at some point of digital transformation, and there really is no linear path. If a utility is struggling with an excessive number of pipe bursts or aging infrastructure that needs to be urgently replaced, this is an excellent entry point for injecting sensors and control mechanisms to monitor leaks and manage pressure.

Recycled water showed less toxicity than tap water in new study

By ES&E Staff

Anew Stanford University study shows that after treating potable reuse water, it can often be cleaner and more dependable than conventional drinking water sourced from pristine-looking rivers.

Many rivers have wastewater discharged in them with much less treatment than occurs in potable reuse systems, suggests the study published in Nature Sustainability. This leaves many contaminants, such as chemicals from personal care products and medicines, floating down river and straight into a drinking water plant.

Reverse osmosis treatment, however, cleans wastewater as much, if not more, than groundwater. Therefore, recycled water can provide a safe, energy-efficient and cost-effective alternative water supply, explained professor William Mitch, senior author of the new study.

“There are additional benefits beyond a secure water supply,” Mitch said in an announcement from the Stanford Engineering department. “If you’re not relying on importing water, that means there’s more water for ecosystems. You’re cleaning up the wastewater, and therefore you’re not discharging wastewater and potential contaminants.”

A wider implementation of reuse water, however, remains hindered by uninformed public perceptions of potential health risks, adds Mitch.

In Canada, a partnership between the University of Calgary’s Advancing Canadian Water Assets program and Alberta’s Village Brewery launched its Village Blonde Natural Golden Ale in 2020 as a way to shine a light on water scarcity and promote Alberta’s first wastewater-treated beer.

Regulators demand more extensive treatment at potable reuse treatment plants. They specify that treatment systems must remove harmful pathogens, such as viruses and amoebas, and that

utilities remove other contaminants using reverse osmosis, ozonation, biofiltration, and other cleaning techniques.

The study’s researchers gauged the toxicity of different sources of tap water by using hamster ovary cells that act similarly to human cells. Whether the cells

slowed or stopped growing compared to untreated cells, helped to paint a picture about the effects of some chemicals. Tap water will carry residual disinfectant, for instance, to prevent pathogens growing in the pipes, said the researchers.

Mitch notes that disinfection is a balancing act between killing pathogens and minimizing exposure to harmful byproducts. “We can’t get to zero contaminants. That would be ridiculously expensive, and probably unwarranted from a health point of view,” he said. The researchers discovered that regulated compounds accounted for less than 1% of the harm to the hamster ovary cells.

In all of the study’s testing, the cytotoxicity of potable reuse waters was found to be lower than that of drinking water derived from surface waters, even in the absence of reverse osmosis.

Seneca College rolls out new avenue for asset management education

By David Nesseth

More and more each year, municipal officials across Canada are learning that infrastructure is degrading faster than it is being repaired, while weighing the risks and costs of inaction. For one group of students at Seneca College in Toronto, the nuances of this modern decision-making process will soon be part of their day-to-day training.

Billed as Canada’s first post-secondary program in asset management, the students will spend eight months, starting this September, learning how to advise municipalities and understand the risks faced by not managing and investing for the long term when it comes to maintaining critical municipal infrastructure.

“Our research shows that any other college program in Ontario dealing with

asset management is actually focused on asset maintenance,” explains Brian Bell, ASM program co-ordinator at Seneca. “The program offers a more holistic education, including a capstone course and a fieldwork component, which blends theory with practice, thus better preparing graduates for a managerial role in the field,” adds Bell.

In recent years, the Canadian Infrastructure Report Card has helped to highlight the risks around aging infrastructure, noting that many roads and bridges, as well as libraries and community centres, are more than 20 years old.

In many parts of Canada, experts are also sounding the alarm about the need to play catchup when it comes to repairing aging infrastructure. Now, upgrades are focusing on making infrastructure more resilient to the effects of climate change, such as strong winds and flooding. In Ontario, for instance, a recent Financial Accountability Office of Ontario projection found that extreme rainfall alone may cost municipalities in Ontario an additional $700 million a year to maintain storm and wastewater assets.

These emerging threats from climate change, as well as population growth, funding models, and service level expectations from taxpayers, are just the beginning when it comes to students learning about managing a community’s budgetary needs against critical services, not to mention the need for accurate data and condition surveys that address wear and tear.

In the first semester of Seneca’s ASM program, students will venture into areas of maintenance management, procurement and supply chain, as well as financial mathematics. In semester two, they will touch on areas such as information and data systems, life cycle management, and sustainability, while preparing for a capstone project, where they will work with an industry partner on a real-world assignment, explains Bell.

“We have been able to build a strong and diverse faculty team with industry experience in many different aspects of asset management,” continues Bell, who has been with Seneca for more than a decade and has a mixed background in business that includes finance, operations and project management. “Our instructors also have lots of experience

in flexible program delivery.”

Available in both full- and part-time formats, ASM instructors will teach students in a classroom or lab and broadcast to students online at the same time. Students come into the program already having a degree or diploma, or partial post-secondary combined with relevant work experience.

The Seneca program aims to prepare students for success on ASM certification exams. School officials are currently in discussions with PEMAC Asset Management Association of Canada and World Partners in Asset Management (WPiAM) about other possibilities relating to certification.

The program currently has an affiliation with the Plant Engineering and Maintenance Association of Canada.

Seneca began investigating possibilities for advanced training in the field after Ontario introduced an Asset Management Planning for Municipal Infrastructure Regulation. Not all provinces have regulations for asset management.

However, in Ontario the process has been phased in since 2019, when municipalities needed to have a finalized strategic asset management policy that promotes best practices and links asset management planning with budgeting, operations, maintenance and other municipal planning activities.

Municipalities needed to have an approved asset management plan for core assets such as roads, bridges and culverts, water, wastewater and stormwater management systems, and identify current levels of service and the cost of maintaining those levels of service, as of the summer of 2022.

Each of the next two years has asset management plan targets for Ontario, including an approved asset management plan for all municipal infrastructure assets that identifies current levels of service and the cost of maintaining those levels of service.

Calls to modernize Canadian Iron Ring ceremony for new engineers continue

By David Nesseth

Engineers Canada, as well as some provincial and territorial engineering regulators, are calling for changes to the private iron ring ceremony for Canadian engineering graduates known as the Ritual of the Calling of an Engineer, which some view as outdated.

The ceremonies take place across Canada at 25 separate groups, called Camps, which differ in rules. In fact, some camps have already implemented more inclusive language. The ceremony typically features the presentation of an iron ring, though often stainless steel, as a symbol of professional duty and obligation. It is intended to be seen as a symbol of professional integrity for many engineers, and be worn on the little finger of one’s working hand.

University of Toronto professor, H. E. T. Haultain, is widely seen as being responsible for the creation of the vol-

untary ceremony around 1922. A similar ceremony has also been adopted in the U.S. as the Order of the Engineer.

In a 10-page letter sent to the Corporation of the Seven Wardens, the signatories suggest they want a new approach to the ring ceremony, which has been unique to more than 500,000 Canadian engineering graduates for 100 years, to “reflect contemporary engineering responsibilities and values.”

A similar call for change to the Wardens, who are volunteer engineers responsible for administering the ceremony, was made in 2020. The more recent driving force for updating the ceremony arose during a roundtable discussion at the 2022 Canadian Engineering Education Association Conference. Particular emphasis was directed at the ceremony’s text authored by Rudyard Kipling, as well as his imperialist background.

The fall 2022 letter does not address

specific passages in the ceremony’s text, but rather addresses the spirit or tone of the “obligation” ceremony. “The ceremony itself is steeped in outdated and harmful worldviews, including colonialism, racism, and sexism,” states the letter to the Wardens.

The letter calling for change adds that the ceremony, or ritual, “does not grant true agency to engineers,” and thus fails to “embody a comprehensive understanding of engineering ethics.” Additionally, the letter notes the ceremony’s “lack of clarity and transparency” in both the ceremony’s text and in the structures and processes of the Corporation of the Seven Wardens.

“While it is clear that the ring itself confers no legal authority, we believe that it is important for the ceremony to present an accurate picture of how engineering responsibility has changed,” the letter states.

Whereas the traditional ceremony recognizes examples of poor engineering works, its critics say that it fails to mention engineers’ “roles in systemic environmental or social issues”, or note the importance of “building and maintaining trust with communities.”

The signatories also note that the ceremony includes readings and symbolism that are inherently Christian and patriarchal, which have made some participants uncomfortable. Some participants have suggested the ceremony’s tone resembles that of a sermon in a Christian church.

In response to complaints about the ceremony, the Corporation of the Seven Wardens announced that it had formed a Ritual Review Committee in early 2022. In a statement, the Wardens noted that

The Ritual of the Calling of an Engineer is a ceremony that features the presenting of an iron ring to be worn on the little finger of one’s working hand as a symbol of professional integrity. Credit: philg24, stock.adobe.com

Some attendees of iron ring ceremonies have also found that its messaging conveys a ‘narrow definition of engineering and engineering failures.’

Kipling’s ceremony text has previously undergone revisions to address “gender neutrality and the removal of religious words and phrases.” They note that “references remaining are made for their poetic and allegoric values.”

The Wardens’ statement continues: “Some stakeholders have expressed urgency in replacing the Ritual immediately. The Corporation wishes to honour the principles of the 100-yearold tradition and to respect all stakeholders’ needs. To do so will require thoughtful input and careful consideration. The current Ritual served its purpose for nearly 100 years. As such, the Corporation wishes that the outcome of the Committee’s work be relevant and enduring for the next 100 years.”

Complaints have also been made over the ceremony’s occasional secrecy, such as participants being advised not to discuss the ceremony afterwards, to friends and families of participants not being allowed to attend unless they are “obligated engineers.”

Some attendees of iron ring, or pin ceremonies, have also found that its messaging conveys a “narrow definition of engineering and engineering failures”. It also focuses on engineering around the types of work that were prevalent when the ceremony was first written, leaving out numerous forms of modern day engineering practice.

The signatories’ letter also includes a series of recommendations about how to modernize the iron ring ceremony, which they consider the text of as “archaic and sometimes ambiguous.”

Some of the suggestions in the letter include actively engaging the present-day engineering community to create a new iron ring ceremony. In particular, the signatories suggest including those who may have felt most excluded by the traditional text for the ceremony, such as women, Indigenous Peoples, and immigrants.

“Our goals are to synthesize and share ideas and concerns, to build momentum, and to work towards constructive change within the engineering community in Canada,” the letter states, noting that it is incumbent upon the engineering community to acknowledge “entrenched and lasting harms.”

The letter also calls for a retool -

ing of the Warden selection processes and a system that would allow for clear accountability.

The list of signatories adds 20 pages onto the letter and includes organizations such as Professional Engineers and Geoscientists of Newfoundland & Labrador; Association of Professional Engineers and Geoscientists of Alberta; Association of Professional Engineers

of Yukon; Association of Professional Engineers of the Province of Prince Edward Island; and the Ontario Society of Professional Engineers.

Interested engineers can email ritual_ review@corp.ironring.ca to send feedback about the current ritual.

Demystifying cybersecurity for smaller water utilities

By Vickitt Lau

Risk assessment and prioritization are vital for critical infrastructure information security. When it comes to the water industry, there is no one-size-fits-all solution, as the industry is fragmented with utilities of different sizes spreading across the nation.

As a whole, this decentralization may be seen as a positive when it comes to data protection and operational control because it would be hard to bring the whole industry down in one cyber attack. Yet, decentralization also means there is a vast difference in security practices and maturity.

As an industry, we are only as strong as the weakest link and hackers are always on the prowl for the weakest link. As cyber threats are continuously evolving, smaller utilities may not have the dedicated in-house cybersecurity expertise and resources to deal with the ongoing challenge.

CONSIDER YOUR VULNERABILITIES

Every organization has a vast cyber threat attack surface. Knowing what these are is the first step to understanding a utility’s vulnerability. For example, over half of cybersecurity incidents occur through third parties. These could be small vendors like accountants, medium-sized vendors like engineering firms, and larger-sized social platforms that most employees use every day.

However, the most vulnerable piece of cybersecurity is the human being. Last year, 36% of data breaches were from phishing. Well-meaning employees can be easily fooled by attackers impersonating people within the organization to convince them to give access or information to things they wouldn’t, if they knew who they were.

Remote access allowed utilities to continue to achieve a higher level of efficiency, transparency and even continued

smooth operation during a pandemic that restricted workers from being in the office, plant or field.

Ensuring secure access to the IT network is key to protecting data and the safe control of SCADA systems. Systems that are not connected to the internet, or air-gapped, are missing out on the digital transformation. It brings a whole new level of efficiency and transparency, allowing authorized personnel to always have eyes on the system, regardless of where they are.

It doesn’t matter whether the operating system is plugged in, if there is an internet connection there is a risk. However, you can be confident in embracing the benefits of a digital utility providing you have a proactive approach when it comes to security.

A STARTING PLACE FOR PROTECTION

Cybersecurity is part of the digital journey; it requires ongoing attention starting with addressing your basic needs and moving on to more complex solutions as you build on top of foundational blocks.

Cybersecurity needs to come from the top down and all employees, regardless of their role, need to follow basic

best practices. Water utilities can use the Center of Security Establishment Canada’s (CSEC) Risk Guide, or find a host of resources at the Cybersecurity & Infrastructure Security Agency (CISA).

The best way to protect systems is with knowledge. Everyone in the organization should understand the basic terms like encryption, VPN, firewall, malware, virus, ransomware, Trojan Horse, worm, etc.

Employers should provide ongoing training and access to processes and policies that are in place to protect employees and operations. Then, when there is a red flag, employees know the right questions to ask and that their concerns will be understood.

There are many little things that make a difference. Don’t share passwords. When something happens, if it feels wrong, it’s probably wrong. Don’t readily give remote control of a computer if someone is reaching out to you. If a utility air gaps, then don’t let people slip in a USB drive. This used to be common practice. Remember coming back from tradeshows with USB giveaways?

PHISHING

It’s a good idea to have an ongoing conversation on the latest phishing scams, continued overleaf…

so everyone knows what to look out for. Social engineering is becoming more sophisticated, hackers are assuming the identity of trusted personnel and accessing people by text, phone and email.

Some organizations put out their own phishing scam tests to identify the most vulnerable people in the organization so that they can bolster training efforts where needed. Consider partnering with software companies that make cybersecurity a priority.

PASSWORDS

No sharing of passwords. This would seem obvious, but people still share passwords or user accounts within an organization and sometimes go as far as posting a sticky note on the computer that is used to access the program. When employees leave, change the passwords. There are many programs that help with password management and ensure that passwords are strong.

ENSURING YOUR SYSTEMS ARE UP TO DATE

Software systems that are out of date are more vulnerable. Be sure to include servers, internet routers, modems and gateways in patching. These updates are often necessary to correct errors and secure areas of vulnerability to new cyber threats. Also, ensure your data backup is up to date.

THIRD-PARTY EVALUATION

There is more often awareness of security inside an organization than on the outside. Water utilities should ask thirdparty vendors if they meet the security requirements for providing a service to a critical infrastructure organization.

Reputable software companies have gone through the rigour of meeting safety standards such as ISO 27001, NIST, FedRAMP, CSE, and others. Companies that have these certifications live and breathe security to maintain it. Utilities can also look at the security scorecard of third-party vendors.

Consumers don’t always bother to read software terms of service and privacy policy, but for an organization, it is important to read, because you have an obligation to know what they are doing with your data and your customer’s data.

SECURE REMOTE CONNECTIONS

Remote work and access are here to stay. One of the best ways an organization can protect itself and its employees is by establishing a virtual private network (VPN). This ensures staff are authenticated through a corporate VPN, before they access other networks to do their work.

Never poke a hole in your firewall to access data remotely. Utilities can install an agent (hardware with software) behind the firewall to act as a gateway and push the data required (on demand, on a timer, or an event) using encryption such as secure sockets layer (SSL) or transport layer security (TLS) encryption for protection while it is in transit.

CONTINUOUS MONITORING

Some vulnerability scanners regularly monitor systems to look for and prioritize threats. There are many different tools available, such as firewalls, antispyware, antivirus software, etc. New threats continually evolve, so if you don’t have skilled experts in-house to stay on top of it, you can use third-party services.

CONTINUOUS SHARING OF INTELLIGENCE INFORMATION

Collaboration with other utilities is another way to stay informed and learn what works from neighbouring utilities and associations. On a broader scale, you can join Water ISAC, an international security network created by and

for the water and wastewater sector. They are an excellent resource to support response, mitigation and resilience initiatives, and are partners with high-profile water associations.

If you do have a cyber attack, be sure to report it to the Canada Centre for Cyber Security and the National Security Information Network.

AN EVOLVING LANDSCAPE

While cyber threats are real and on the rise, software to protect organizations has also evolved. It used to be that a firewall would protect a system’s perimeter and antivirus software protected the inside. New software today looks at behaviour analytics of processes within the system. If your system starts to act unusually, the new software will send alerts or stop the process that is outside of the norm.

In the past security was often seen as the competitor to functionality. Now it is a key function of the business. Thinking has changed from “what I want my product to do” to “what do I want my product to do and how do I do that securely?”. Security is now part of the design phase of software and operations from the very beginning.

An overview on water and wastewater issues in Europe

By Chris Somerville

With so many rivers, streams and lakes across its territory, it may be hard to believe that Europe suffers from water shortage or stress. However, water stress affects over 100 million people living in densely-populated Europe.

Over 88% of Europe’s freshwater is sourced from groundwater and rivers, while the remainder originates from reservoirs (10.3%) and lakes (1.5%). These sources are, of course, vulnerable to over-extraction as well as climate change and human pollution, and the European Environmental Agency (EEA) estimates that around one-third of European Union (EU) territory is under water stress.

Water demand has steadily increased over the past 50 years, partly due to population growth, leading to a decrease in renewable water per capita by 24% across Europe during this time. This decrease is particularly manifest in southern Europe, where declining pre-

cipitation levels are a major factor, according to an EEA indicator.

This begs the question of whether or not the way Europe uses its freshwater resources is sustainable. Annual economic activities draw 243,000 cubic hectometres of water on average according to the EEA, although over 140,000 cubic hectometres of this is eventually returned. Agriculture is the greatest single user of water overall. Although only around 9% of its productive farmland is irrigated, it accounts for over 40% of total water used in Europe.

In the spring, this can jump to 60% when crops are freshly sown, especially for high value produce like olives and oranges, which require considerable amounts of water to mature. Despite improvements in water efficiency in the irrigation sector (crop production in Europe became 12% less water intensive between 2005 and 2016; the total water input to crops under rain fed and irrigated conditions for each unit of gross value added generated from crop pro-

duction, decreased from 5 m³ to 4.4 m³ over this period), agriculture will continue to be the largest single consumer into the near future.

This is because more and more farmland will become irrigated, especially in southern European countries as they continue to develop economically. Certain sectors, mass tourism in particular, amplify the demand for water in some regions during key periods. Every year, millions of tourists visit destinations across Europe, especially the warmer areas of southern Europe, accounting for some 9% of total annual water use.

Interestingly, energy generation also needs a lot of water, accounting for around 28% of the total, predominantly for cooling in nuclear and fossil fuel plants. Mining and manufacturing account for 18%, followed by household usage at 12%. On average, 144 litres of water per person per day are supplied to households across Europe.

The sector with the largest water use differs from country to country, but generally, agriculture is the highest user in southern Europe, while cooling in power generation is the single largest user in both western and eastern Europe. The manufacturing industry tops the list in northern Europe.

Over the past 30 years, substantial progress has been made by EU member states to improve. Another key piece of legislation is the Drinking Water Directive that concerns quality of water intended for human consumption; member states have until 2023 to transpose it into national legislation. These legislations reflect the European commitment to improving the state of water resources.

Yet, in spite of the progress achieved so far, the overall health of Europe’s water bodies remains precarious. The vast majority of Europe’s lakes, rivers, estuaries and coastal waters struggle to meet the EU’s minimum “good” ecological status target under the Water Framework Directive.

To help alleviate this problem, the new Circular Economy Action Plan published by the European Commission (EC) in March 2020 establishes a framework for moving away from the predominantly linear system of production and consumption. The Action Plan

also acknowledges the potential of water reuse in agriculture and industrial processes to further alleviate pressures on freshwater resources.

Annually, European water services invest approximately $70 billion in total in water infrastructure. This means that, on average, roughly $127 is invested per citizen per year as of 2021, financed mainly through water bills, taxes and government transfers. The investment level depends on many factors, including upgrade requirements, cost of labour, and more.

Water billing in Europe is a complex topic as it depends on many local considerations like tax levels, water sources (groundwater typically requires less treatment than surface water), length of network per inhabitant, receiving waters after treatment (sensitive areas require a higher level of treatment), and more.

Meanwhile in the UK specifically, water utilities providers invest $9 billion in assets and $8 billion in services per year, employing 45,700 people and sustaining 86,000 indirect jobs.

Approximately 400 water companies generate revenues of $2.3 billion. The Water Environment Regulations 2017 provide the legal and policy framework in the UK, which applies to surface waters, some coastal waters, and groundwater. These regulations set out the requirements to prevent the deterioration of aquatic ecosystems, protect, enhance, and restore all water bodies to a ‘good’ condition, and achieve compliance with standards and objectives for protected areas.

The relevant legislation for wastewater is called the National Policy Statement for Wastewater, and the industry is highly regulated by the Water Services Regulation Authority. It must be noted that the above legislation applies only to England and Wales where water services were privatized in 1989. Scotland manages both water and wastewater publically and these services are provided by Scottish Water, which remains under government ownership.

In 2020, the Guardian reported on the release of England’s Department

for Environment, Food, & Rural Affairs report concerning the state of English rivers. Testing revealed that just 14% of them were of “good” ecological standard, and none met the “good” chemical standard in spite of the efforts of the nation’s water and wastewater services. There was no noticeable improvement in their quality since 2016, when this last test was performed.

The culprits are discharges of raw sewage directly into water, chemical releases from industrial plants, and agricultural run-off. English water companies themselves took blame because of combined sewage overflows caused by heavy rains that overload sewer systems, discharging into rivers or the sea on multiple occasions. English water quality stands in contrast to that in Scotland and Wales, where 65.7% and 64% respectively are considered of “good” ecological quality.

The Urban Waste Water Directive (UWWT) was first adopted in 1991 (although further amended). The main continued overleaf…

objective of UWWT, and equivalent national legislation for non-EU countries, is to protect the environment, specifically surface waters, from the adverse effects of irresponsible wastewater discharge containing oxygen-consuming organic pollution, which damages aquatic life, and microbiological contamination of pathogens.

This is achieved through the collection and treatment of wastewater in populated areas and localities where population and economic activity are sufficiently concentrated (agglomerations), with the polluting load generated expressed as a population equivalent (p.e.). The UWWT covers agglomerations over 2,000 p.e.

In most cases, it stipulates that wastewater must be subject to biological treatment (secondary treatment), but in catchments of particularly sensitive waters, such as those suffering from eutrophication, more stringent tertiary wastewater treatment is required to substantially reduce nitrogen and phosphorus pollution.

Meanwhile, both quantitative and qualitative improvement of wastewater treatment in Europe has taken place. The UWWTD and the EU Water Framework Directive provide the strongest market stimuli—especially in eastern and southern Europe. In contrast, maintenance, facility renewals, as well as procedures for reducing operational costs, primarily to reduce energy consumption, dominate procedures for the improvement of wastewater processes in central and northern Europe.

In 2020, most European countries collected and then treated sewage to a tertiary level from most of their populations. In EU-27 countries (EEA 2020), and not just in cities, 69% of the total population was connected to tertiary level treatment and 28.5% to secondary level treatment.

Countries where less than 80% of the population (total population—not just from cities) were connected to public wastewater treatment systems were Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Ireland, Italy, Lithuania, Poland, Romania, Serbia, Slovakia and Slovenia.

Meanwhile, across the whole EU (not including non-EU members), around 90% of urban wastewater from cities is collected and treated in accordance with

Chart — Urban waste water treatment in European "Big Cities" in 2016

the UWWTD, while four countries, Austria, Germany, Luxembourg, and the Netherlands treat 100% of their urban wastewater to a tertiary level.

Recently, investment in treatment of urban wastewater, particularly in the newer EU member states, has been directed at developing tertiary treatment (Bulgaria, Czechia, Estonia, Hungary, Latvia, Lithuania, Poland, Romania and Slovenia). However, there are still several countries where more than 40% of the population were only served by treatment below tertiary in 2017 (Albania, Bosnia and Herzegovina, Ireland, Malta, Portugal, Serbia, Slovakia, Turkey and the United Kingdom).

Recent research into COVID-19 has also shown the potential of monitoring non-infective traces of the virus in untreated wastewater, to rapidly estimate the level of infection in a large population. This is being actively performed in some European cities. By checking wastewater samples, cities like Berlin are now identifying which variant of COVID is most predominant in the city, as well as the amount of caseloads in the city so that the relevant authorities can be forewarned.

FUTURE WATER AND WASTEWATER DEMAND

The market for fresh water and municipal wastewater treatment plants in Europe will continue to grow in the long term. Over the past 20 years, the number of municipal wastewater treatment plants in Europe has steadily increased, while technical standards improved.

THE NEED FOR RELEVANT TECHNOLOGIES

With the push for total water sustainability growing ever stronger, the demand for relevant technologies is expected to increase accordingly. For water purifiers, innovation is projected to be the motivator of every company that wants to make it big in global water purifiers.

A second technology that European firms will be in need of is UV disinfection equipment. These systems are witnessing increasing adoption across a broad array of applications, including air, water and food disinfection. UV technology is anticipated to witness extensive uptake owing to its compelling merits, like relatively low investment capital and operating and maintenance costs, along with convenient installation.

Within Europe, the demand for this specifi c technology in Germany is forecast to grow at approximately 15.2% compound annual growth rate, while the rest of the European market will reach CAD $2.92 billion by 2026.

Paving the way to make cities more rain ready

By Mark Douglas Wessel

In August 2022, a headline on the CBC’s website read “More rain fell on Ottawa in days than in a typical August.” The story went on to point out that as a result of multiple storm cells passing through the area, the city was battered with 116 mm of rainfall within 48 hours. This is more rainfall than the city normally experiences for an entire month.

A few weeks later, CTV News ran a story tied to an Environment Canada rainfall warning for Ottawa that predicted a similar downpour of 50 mm to

75 mm within a 24-hour period, noting that “heavy rainfall can cause flash floods and water pooling on roads”.

The increased frequency and threat of what were once known as “100-year storms”, now occurring within a span of a few years, is not unique to Ottawa, of course. Cities from around the world must now contend with this challenge as a result of climate change. As warmer oceans and lakes are significantly increasing the volume of water that evaporates into the air, inevitably it comes back down to earth with a vengeance.

What is unique about Ottawa, at least in comparison to the rest of Canada, is that it is currently the only city in the country with a program known as Rain Ready that incentivizes homeowners in flood-prone neighbourhoods to deploy a variety of options to absorb rainfall and keep it on-site. Options include the installation of permeable paving driveway, rain gardens, soak away pits and downspout redirection.

AN INCREASED FOCUS ON STORMWATER MANAGEMENT

In a recent interview, Julia Robinson, who is the project lead for the City of Ottawa’s climate resilience strategy and has been directly involved in the Rain Ready program since it began a couple of years ago, observed that the Ottawa River Action Plan was the starting point which ultimately gave rise to the program.

There are opportunities for municipalities, engineers and builders to replace hard surfaces with permeable surfaces such as PurePave (pictured).

The Ottawa River Action Plan “was a major strategy that identified a number of key issues and a number of projects that are being implemented…and a result of that, there was an increased focus on looking at how do we tackle the issue of stormwater management,” Robinson said. She added that this in turn “led to two very detailed engineering studies in our priority neighbourhoods where stormwater management and stormwater runoff, was deemed to be the highest problem.”

From there, private property management was identified by the city as one of the top solutions. Robinson states that “if we are able to achieve a scale of management of stormwater runoff on private property…it would really contribute to helping reduce the harmful runoff, both from a water quality and water quantity perspective.”

While the city is actively seeking to engage and support the involvement of the landscape architect community tied to such projects as rain gardens, Ottawa is also witnessing a spike in demand for permeable paving solutions, catalyzed by Rain Ready incentives. Ottawa-based PurePave Technologies has been involved in meeting this demand.

A NEW GENERATION OF PERMEABLE PAVING

PurePave surfaces are made from a natural aggregate with a polymer bonding agent, so that multi-coloured stones are used. As a result, some homeowners have opted for design patterns that can be incorporated into the driveways, walkways, house and pool surrounds and patios.

PurePave surfaces are designed to absorb the equivalent of up to 14,000 m3 of rainfall per hour. University of Ottawa tests have confirmed that the surface is six times stronger than asphalt and 1.6 times stronger than cement. This translates into a life expectancy of 40 years.

Because of such performance indicators, apart from the residential homeowner market, the company is also doing a growing volume of commercial property business. Past projects were mostly smaller, including installing permeable paving in flood prone sections of commercial plazas.

However, the scope and variety of PurePave installations continues to evolve and

includes parking lots for developers, city medians for green streets initiatives, a similar project for the Toronto Metropolitan University and most recently for the Toronto Zoo.

PurePave CEO and founder Taylor Davis says that “there is also an opportunity for municipal staff, civil engineers and residential builders to replace hard surface driveways and parking lots altogether and substitute highly permeable surfaces such as PurePave, combined with new maintenance technologies”.

These surfaces are also cooler thanks to their porosity which vents rather than absorbs heat unlike more conventional surfaces such as asphalt. This can help alleviate the growing threat of heat islands in major cities.

RETHINKING STORMWATER SOLUTIONS

Davis says that his company is now in active discussion with municipal staff in cities like Ottawa and Toronto, as well as a handful of transportation infrastructure and environmental service companies, to explore more modern solutions such as the idea of more extensive, community-wide use of permeable surfaces. This is already taking place in countries such as the Netherlands, with the “sponge city” mindset they have embraced.

This approach, together with bioengineered solutions, public parks and other spaces that double as flood catchment areas, could significantly reduce municipal infrastructure costs.

So, instead of expanding the water handling capacity of the city, it could be far more cost-effective to ramp up a program like Rain Ready, while implementing other “sponge city” solutions.

“If all of the residential driveways in a new subdivision used permeable surfaces, it could eliminate the need for stormwater ponds altogether. This could free up land to build more homes or create more neighbourhood amenities such as public parks,” observes Davis.

SMARTER SOLUTIONS

PurePave, in collaboration with professors at the University of Ottawa, is planning to install sensors just below its surfaces in selected locations. These will precisely measure the volume of rainfall within a set period of time. The goal is to automate maintenance schedules, monitor water quality, and to compile more accurate data that cities can use to have a better handle on rainfall events. This information can then be used to determine what, if anything, needs to be done to existing infrastructure in order to create more resilient communities.

This kind of data, together with a new way of thinking about how rainwater is managed in the first place, will help to build communities that are more resilient in the face of global warming.

New technologies help locate water pipe leaks

By ES&E Staff

Anglian Water, a large U.K. water and wastewater utility, is taking advantage of unusually dry conditions by using drones to spot water pipe leaks that may have otherwise gone undetected in full reservoirs.

With nearly 40,000 km of water pipe to monitor, often in rural and remote areas, aerial technology, combined with low water levels, helps operators spot unusual flora growth that can often pinpoint leak locations.

The company says it is investing millions in advanced technology, including pressure management and system optimization, to help it achieve leakage rates per kilometre of watermain that are half the industry average.

“These leaks are usually really difficult to find,” explained Chris Utton, Anglian’s leakage delivery support manager, in a statement. “In the past, drones have helped us find and fix leaks on sections of pipe that we had previously planned to replace.”

Anglian officials have used drones since 2017. The company estimates that the technology can save as much as $11,000 per flight in water lost through leakage, prevent unnecessary pipe replacements, and help to keep customers’ bills low.

“Our previous work usually focused on thermal imaging, to find different temperature patterns, but the 2022 drought gave us the opportunity to spot leaks in a new way,” said Utton.

In Canada, cities like Hamilton, Ontario, have also begun to use new ways to detect leaks. In early 2021, it introduced magnetic listening devices to fire hydrants and isolation valves to listen for leaks that could be within 100 metres. The listening took place between 2 a.m. and 4 a.m. when water usage and traffic noise are typically less, meaning reduced interference and more accurate readings. After locating a potential leak with the listening device, crews would

head into the field to pinpoint the exact leak location.

Hamilton officials said that at the end of 2021, proactive leak detection technology was deployed to more than 5,990 locations and had identified an additional 109 leaks (17 of these leaks were located on private water service lines). The detections saved the city an estimated $537,068.

Also in 2021, a study by the Residential and Civil Construction Alliance of Ontario (RCCAO) found that cities such as Toronto could be wasting as much as 103 million litres of treated drinking water daily due to leaky or broken pipes. The leaks could stem from bad connections, internal or external corrosion, or mechanical damage caused by excessive load.

A 2018 survey of 308 water utilities in North America showed that the typical age of a failing watermain is 50 years.
