The City of Toronto has selected Stantec to provide design and construction administration services for its new High Rate Treatment Facility (HRTF). The project will help reduce combined sewer overflows and improve water quality in the Lower Don River, Taylor-Massey Creek and along Toronto’s Inner Harbor.
The new facility, to be located on the new landform at the Ashbridges Bay Wastewater Treatment Plant, will be a key component of Toronto’s broader wet weather flow management program. That program — known as the Don River and Central Waterfront Wet Weather Flow System — is the largest and most significant wet weather flow management program in the Toronto’s history. Stantec said the HRTF will be one of the final projects in the program and will help the city achieve broader environmental protection benefits.
According to Stantec, the treatment facility will be a 600-million-litre-per-day plant and will provide primary treatment for excess flows captured during wet weather events. The project builds on a network of tunnels and infrastructure that manages combined sewage and stormwater flows across Toronto.
Once complete, the facility will play a vital role in reducing combined sewer overflows during wet weather events, helping to protect the environment, support recreation and improve the health of the city’s waterways.
“Toronto is making an important investment in protecting its waterways and preparing its infrastructure for the future,” said Jeff Berg, vice president and project manager at Stantec. “We’re pleased to work with the City to provide a solution that enhances water quality, safeguards public health, and strengthens climate change resilience.”
Stantec will work with the city and construction team through a collaborative delivery model, the construction manager at risk method, which brings the construction manager into the project early to provide input on design, constructability, scheduling and cost management.
The work is currently in the design and engineering phase. Construction is scheduled for completion in 2036.
Stantec and Toronto Water Infrastructure
Stantec has a long history of working with the City of Toronto on water and infrastructure projects, including several phases of the City’s Basement Flooding Protection Program and multiple phases and sections of the elevated Gardiner Expressway Rehabilitation Project. This experience provides a strong foundation for delivering the HRTF as part of the City’s integrated approach to wastewater infrastructure.
