The Don River and Central Waterfront Wet Weather Flow System & Connected Projects is a 25-year program aimed at improving water quality in Toronto’s Lower Don River, Taylor-Massey Creek, and Inner Harbour. Toronto is embarking on the largest and most significant stormwater management program in the city’s history, and with an overall budget of more than $3 billion, this 25-year program will greatly improve the water quality in these areas by keeping combined sewer overflows out of the waterways through the upgrading of technology and capacity to capture, transport, and treat it. The project is comprised of an integrated system of tunnels, storage shafts, a high-rate treatment facility, and wastewater treatment plant upgrades. The Program is made up of several individual projects that will work together, including the Don River and Central Waterfront Wet Weather Flow System, the Ashbridges Bay Treatment Plant (ABTP) Integrated Pumping Station, ABTP UV Disinfection facility, ABTP Landform and High-rate treatment facility, and ABTP Outfall. Construction of the Coxwell Bypass Tunnel is scheduled for completion in 2023. The Ashbridges Bay Landform Project, a joint initiative between the City and the Toronto Region Conservation Authority (TRCA), as well as projects at the ABTP are all well underway. These include the Integrated Pumping Station, the Landform Project, the ABTP UV Disinfection facility, and the ABTP Outfall. (repeats?)

When this stage 5 project by Metro Vancouver is complete, the Annacis Island facility will have increased its capacity to serve 1.5 million people in 14 Metro Vancouver municipalities, from its current ability to serve 1.25 million people. The previous expansion was done in the late 1990s. The plant serves much of the Tri-Cities, Burnaby, Maple Ridge, Delta, Surrey, Pitt Meadows, Langley, and White Rock. Four proponents have been shortlisted for the outfall project, the next phase of the Annacis expansion. 

“The Annacis Wastewater Treatment Plant is one of the region’s largest wastewater treatment facilities, serving 14 Metro Vancouver municipalities. Over the next several years the plant will receive major upgrades in order to meet the needs of our region’s growing population.

Bonnybrook Wastewater Treatment Plant is the largest of three wastewater treatment plants serving Calgary and the surrounding area. Originally built in the 1930’s, Bonnybrook is undergoing its most substantial upgrade to date. With an investment of more than $1 billion dollars over the span of 10 years, it is expected that Bonnybrook will see its total treatment capacity increase to nearly 1.4 million citizens when completed in 2026. In 2021, the project made significant progress, and the greatest number of projects were completed and commissioned, including the installation of two new primary clarifiers and six additional secondary clarifiers. The project also entailed the construction of three secondary treatment bioreactors and retrofits, and upgrades to existing solids handling digesters and the UV disinfection facility. Lastly, as part of this Plant D upgrade, a new bio-gas handling storage facility was completed and commissioned. In Spring of 2021, a new outfall was commissioned and put into service. This new larger outfall was built 900 m further downstream to provide additional flood resiliency and an improved diffusion system to enhance environmental performance.

The Springbank Off-stream Reservoir represents the Government of Alberta’s solution to mitigate severe flooding along the Elbow River, similar to what took place in June of 2013. Current plans call for a dry reservoir with a capacity of 70.2 million m3 and an outlet structure to safely release the water back to the river. The reservoir will be located approximately 15 km west of the City of Calgary. In October 2021, voluntary agreements were reached with landowners to secure the 3,700 acres of land needed for the project. The tendering process for construction has begun, with tenders sent to pre-qualified bidders. Construction is slated to begin in early 2022. Alberta Environment and Parks will be responsible for the operation of the project once construction is complete.
