As our communities are embracing the need for greater sustainability, infrastructure security, and resilience, it may be time to evaluate and implement a more local alternative. This can be a distributed network of decentralized wastewater treatment and resource recovery facilities.

Generally, the two most accurate meter technologies are static meters, which includes ultrasonic and magnetic flow meters. Both have their advantages, but the right fit will depend on the application. This makes it important to understand the pros and cons of each technology before making a purchase.

Opinion: Our industry has been messaging for years that toilets are not trash cans, but women’s toilet stalls are not provided with trash cans!

Nick Winters, director of Hamilton Water, says that “Lead plumbing material is an issue for the City of Hamilton, our residents, and our industrial, institutional and commercial customers as well. So, we knew it would take multiple approaches to identify the extent of the problem and different tactics to mitigate the effects of lead as quickly as possible.”

Maintaining an efficient and reliable sewer system is a critical task for any city. To meet these challenges, innovative technologies are being employed to streamline maintenance processes and reduce costs. One such technology is acoustic inspection, which is a fast, low-cost, and highly effective method for assessing small-diameter gravity sewer lines.

The Northwest Inner City area of Calgary has recently experienced unprecedented flooding, the most devastating of which was the Bow River flood in 2013. This significant event refocused the city’s priorities in this area on drainage improvements. In 2019, the City of Calgary initiated three community drainage improvement projects.

Accepting diapers as part of a source separated organics (SSO) program increases the participation rate, but does pose challenges and opportunities.

The project team had already instituted some flood protection measures. It reviewed the scouring at the river edge and at the well sites, as well as wellheads for evidence of breaches of flood water. The team also reviewed the aerial photos of the upper watershed for signs of new hazards and contaminants of concern.

When it comes time to invest in equipment, selecting low-maintenance sensors that resist fouling and abrasion and don’t need frequent calibrations to preserve their accuracy goes a long way toward optimizing process control. Galvanic dissolved oxygen sensors are popular for their low initial investment.

The distinct structure and functionalities of butterfly valves, coupled with their compliance with various industry standards, make them a practical choice in demanding environments.

A simple choice of material can impact the design life, function, and performance. One change that has all three beneficial outcomes for water distribution is moving from nitrile (Buna-N) to ethylene propylene diene monomer (EPDM) for valve seats.

At prototype PFAS source zones, the in situ pilot test treatments resulted in the immediate, complete, and sustained elimination of PFAS in soil leachate.

Companies with their own wastewater management facilities are facing a number of challenges, but there are technologies and practices offering solutions.

A prudent approach to Arctic water system design is not if the system is going to freeze, but when it is going to freeze, as things can go wrong.

Thoroughly understanding the nuances of the chemical’s properties is vital to maximize the operation and performance of the chemical delivery system, as well as the longevity of the chemical storage tank. If you simply design a tank based on generic factors such as size, material and capacity without defining the chemical used, you risk getting a non-optimal tank.

The recovery of as much surplus heat (or cooling capacity) as possible after the primary function of the heat exchanger has been performed can be reused to either improve the efficiency of the heat exchange process or used elsewhere. Recovery and reuse of industrial waste heat is an attractive concept that could simultaneously reduce energy costs and CO₂ emissions.

Exposure to the hazards and toxicity of PFAS in drinking water has been a worrisome reality worldwide. As such, many methods have been used to test its presence in human biological fluids, including whole blood, blood serum, breast milk, as well as hair.

A former Smiths Falls water treatment plant with two heritage designations was severely damaged in a May fire. Now, local officials of the eastern Ontario town are weighing demolition versus stabilization, which both have...

Canada and two provincial governments are making substantial water and wastewater infrastructure investments in the British Columbia community of Bowen Island and the New Brunswick Town of Rivière-du-Nord. For the B.C. island municipality of just...

The University of British Columbia’s (UBC) Bioreactor Technology Group says it has found a cost-effective method to extract phosphorus from wastewater sludge and convert it into a practical solid residue called hydrochar. The extraction process...

A new survey suggests that operational costs for wastewater utilities could increase by more than 60% — some three times higher than federal projections — as a direct result of new PFAS regulations in...

Flash flooding damaged a pump station in the Nova Scotia community of Bedford recently, causing sewage to flow into Sandy Lake.  The flash flooding damaged the pump and its electrical systems, taking the station offline...
