Dinner with Prince Philip’s private detective in 1967 changed my career
By Tom Davey
Editor’s note: Prince Philip, Duke of Edinburgh passed away on April 9th just two months shy of his 100th birthday. A dynamic figure, he touched the lives of thousands of individuals during...
Pipeline design provides stormwater runoff control for West Vancouver neighbourhood
When completed, the project will increase the level of flood protection for homes below the Upper Levels Highway. Rerouting the excess stormwater will also reduce erosion, help to safeguard residents and property while accomplishing its original goal of protecting the watershed health of the Five Creeks drainage areas.
Stormwater funding gap increasingly in the spotlight
Jurisdictions across Canada are experiencing longer and more intense precipitation events as a result of climate change. This has highlighted capacity issues in stormwater infrastructure that go above and beyond the need to rehabilitate existing assets. Stormwater, or urban runoff, has become one of the most significant pollution threats in the eyes of some environmental experts.
ECO Canada releases report on financial compensation of environmental workers
According to ECO Canada’s latest labour market outlook, employers will need to hire approximately 172,700 new environmental workers by 2025 due to sector growth and retirement. This represents nearly 25% of 2020 environmental employment levels (about 620,100). Around 74,400 of these will be new green jobs resulting from sector growth.
Automated wastewater treatment systems help with compliance and reduce costs
An automated wastewater treatment system can eliminate the need to monitor equipment in person while complying with mandated requirements. Such auto-mated systems separate suspended sol-ids, emulsified oil and heavy metals, and encapsulate the contaminants, producing an easily dewaterable sludge in minutes.
Understanding the testing requirements under Ontario’s new excess soil regulation
The premise of Ontario’s Regulation 406/19 is that soil is a precious and limited resource and, as with any limited resource, excess soil generated from construction and earthmoving projects needs to be properly managed.
Optimizing Kelowna’s water system improves coverage and multi-use
In 2017, the City of Kelowna, British Columbia began the process of separating agricultural and domestic water systems as part of its integrated water supply plan. It calls for an integrated water system that provides the lowest cost, city-wide solution for drinking water, that also maintains agricultural interests.
Accelerating digital transformation in the water industry to improve efficiency
Tech-savvy water utility managers understand that centralizing operational data into one unified system can help achieve both goals, while boosting efficiency and improving long-term asset performance.
Digital twins equip utilities to proactively manage and improve water systems
Digital technologies are advancing the development of sustainable water systems. One of the most leading-edge digital solutions today is the use of digital twinning for water systems.
Cambridge’s Hespeler WWTP adopts membrane aerated biofilm reactor technology
While the first phase of improvements was underway at Cambridge’s Hespeler WWTP, a study was done to evaluate the merits of installing membrane aerated biofilm reactor (MABR) technology for secondary treatment.
Advanced biological filtration provides multi-barrier approach to complex contaminant removal
Traditional treatment plants were not designed to remove modern organic and synthetic contaminants. Recognizing this, many municipalities are searching for new ways to effectively meet the challenge.
Testing an oxygenation system at a sewage lift station for odour control
At a lift station in Alberta, the ability of oxygenation technology was tested for wastewater odour control at the forcemain discharge and to determine the capacity required to provide effective control of corrosion and odour.
Florida cyberattack raises public awareness of threats to water plants
As utilities increasingly take advantage of the automation available through modern SCADA technology, they will also need to upgrade their cybersecurity measures to protect their more technologically-advanced systems.
Nearly $90M in funding could jumpstart water work for 37 Ontario First Nations
Canada is investing $69.5 million for clean drinking water, wastewater and stormwater infrastructure improvements in 37 First Nation communities across Ontario.
The new funding will also address drinking water pipes; communal drinking water systems; sewage...
Saskatchewan city links recent sewer clogs to flushed masks
As water workers discover more blockages in sewer lines, the Saskatchewan City of Prince Albert has issued an advisory to its 36,000 residents to stop flushing face masks down the toilet.
Geoff Soderberg, Prince Albert’s...
Selkirk’s new WWTP equipped to serve double current population
The two-year construction of a new $39.5-million wastewater treatment plant will be completed for the Manitoba City of Selkirk this summer, offering the capacity to serve more than double the current population of about...
Filtration milestone for NWT water treatment plants coincides with call for new facility
After decades of simple truck-fill water stations with chlorine disinfection, communities in the Northwest Territories (NWT) have reached the milestone achievement of having filtration in all of its water treatment plants, government officials announced.
The...
