Green innovations making constructed stormwater facilities more accessible to smaller communities in Manitoba
What many don’t realize is that Manitoba has been leading the way in water initiatives for some time by employing innovative green infrastructure projects since the early 2000s.
Using electro-ceramic desalination to remove metals from industrial wastewater streams
There is increasing demand for products where the manufacturing facilities and processes generate metal wastewater that present numerous challenges. Increasingly strict regulatory requirements are putting the squeeze on capacity and complicating compliance for industrial wastewater treatment.
Life cycle analysis proves in situ approach is more sustainable and cost-effective for PFAS...
Remediating PFAS will require a tremendous response to address thousands of contaminant plumes in groundwater in Canada alone. Since PFAS do not biodegrade, they migrate farther than most common groundwater contaminants, such as benzene, trichloroethylene (TCE), with plumes often extending well beyond their sources, affecting large aquifer volumes.
Analyzing sediment depth accumulations in installed oil-grit separators
For several decades, oil-grit separators (OGS) have been used in Canada to treat stormwater runoff and snowmelt from roadways, parking lots, fueling stations, and other impervious areas located on commercial, industrial and residential development sites.
The importance of attending regional water and wastewater association events
Compared to the big city shows, the Northwestern Ontario Water and Wastewater Conference event may seem small, but more than 150 enthusiastic water and wastewater professionals attended the two-day event to join their peers and learn about new policies, trends and technologies related to their industry.
Lift station upgrades position Manitoba town for future growth
When two of Altona's four lift stations began experiencing frequent clogging issues a decade ago, the Manitoba town's public works department replaced the existing pumps at lift stations 2 and 3 with Flygt N style impeller conversion kits for each of their pumps.
What a year 2023 turned out to be!
In January, my wife and I were blessed with a second granddaughter, making us three-time grandparents. A wonderful time of our lives indeed, but one that we have found brings the return of protective paternal and maternal instincts. Myself, I experienced a new anxiety over the state of the global environment.
Water fleas hailed as latest wastewater treatment technology in new study
Water fleas, most of which average less than five millimetres in length, could play a new role as chemical pollutant vacuum cleaners for wastewater, says a University of Birmingham study in the U.K.

Metro Vancouver forms task force to guide unfinished North Shore WWTP project
Metro Vancouver has formed a new task force to review all available options for completing the troubled North Shore Wastewater Treatment Plant project.
Local officials terminated their contract with the plant’s original builder in 2021...
FCM’s Green Municipal Fund paved way for nearly 1,500 projects since 2000
Over the course of more than two decades, the Federation of Canadian Municipalities’ (FCM) Green Municipal Fund has enabled the completion of nearly 1,500 projects aimed at cutting greenhouse gas (GHG) emissions in the...
Ontario’s Mapleton returns to privatizing water system expansion in face of housing pressure
Ontario’s Mapleton Township is returning to its plan to privatize its water and wastewater expansion, after terminating a similar deal at the height of the pandemic in 2020.
Mapleton Chief Administrative Officer Manny Baron told...
New study sheds light on varying stormwater measures across U.S. cities
A new study attempts to identify meaningful patterns among different stormwater control measures in 23 cities with varying climates across the U.S.
The study, produced by researchers from six universities, as well as the Water...
Hamilton’s StreamGo engages in PFAS removal project with Buffalo Sewer Authority
New York State's City of Buffalo is utilizing an advanced oxidation technology targeted at per-and polyfluoroalkyl substances (PFAS) that was developed by Ontario-based water company StreamGo.
Buffalo’s work with StreamGo, based near Hamilton, may even...
2023 Consultants Forum
What is a consultant’s role in helping clients adopt new technologies and managing change?
As engineering consultants, we rarely discuss our role in advising and assisting clients with adopting new technologies and managing change — even though they trust us to deliver infrastructure projects, and seek our assistance in planning, selecting, implementing, and testing technology solutions.
When a design team makes errors, or does not pay attention to details, operations...
When he was a toddler, my wife taught my son a song that they sang together at crosswalks: “Red means stop, green means go, and yellow means pay attention.” The greatest risk to a young pedestrian is during the transition when vehicles stop for a red lightand start for a green light. Similarly, the greatest risk to a design occurs when “we fail to pay attention” while developing a design.
Why now is the time to ensure the future success of the environment sector
The next 10 years represent a critical time for Canada’s earth and environment sector. Climate impacts are getting worse, and our industry is scrambling to help reduce carbon emissions, save sensitive ecosystems, restore biodiversity, and plan future development that is climate resilient.
Complacency to catastrophe: The perils of neglecting cybersecurity
In the fast-paced world of consulting engineering, where digitization is as much a part of the daily grind as our morning coffees, we may not fully appreciate the impact cyberattacks can have on our ability to serve clients.
How engineers and Indigenous communities can redefine consultation
The new consultation guideline, produced by Engineers Canada’s Canadian Engineering Qualifications Board (CEQB), is considered a living document designed to provide project leaders with a practical tool for conducting more meaningful engagement between engineers and Indigenous communities.
Engineering firms can bolster internal teams by hiring outside consultants
One person, or firm, cannot be the best at everything. Many owners and engineering firms struggle to find the perfect combination of skilled and experienced staff to meet their needs in today’s changing world.
2023 Operators Forum
Proper maintenance helps limit sanitary sewer overflows
One of the greatest underlying causes of sanitary sewer overflows (SSOs) is sewer pipe blockages due to growing tree roots that enter through line defects or openings, combined with inappropriate materials sent to sewers. This includes fats, oils, and grease along with products like baby or facial wipes, sanitary pads, and tampons.
New and seasoned Indigenous water operators recognized for their achievements
At the same time as First Nations communities are preparing to welcome a new cohort of water treatment plant operators freshly trained in Northern Ontario, recently a national award provided a glimpse from the other end of the lens into the water career milestones of seasoned Indigenous operators.
Four important reasons to choose CO₂ to reduce drinking water pH
The pH level of water plays a significant role in every stage of a municipal water treatment system, from disinfection to filtration, to corrosion control. As such, proper management is essential for optimizing the performance of treatment processes. Maintaining optimal pH levels is crucial in drinking water treatment to ensure the safety and quality of the water supply.
