en.Wedoany.com Reported - Canada's water sector is shifting from responding to extreme weather to systemic climate adaptation investments, with three key infrastructure projects established as industry benchmarks.
In Toronto, the Fairbank Silverthorn Storm Trunk Sewer System, costing over $350 million CAD, is under construction as the city's largest basement flood protection program to date. The project aims to protect over 4,600 homes and businesses within a 140-hectare area. The main line is a 4.5-meter diameter, 2.4-kilometer long tunnel buried up to 50 meters underground, excavated using an earth pressure balance tunnel boring machine. It received the Tunnelling Association of Canada's 2025 Design Innovation Award for its innovative design. Once fully operational with over 15 kilometers of new local collection pipes, the system will prevent 40 million liters of polluted combined sewer overflow from entering Black Creek annually.
British Columbia's Abbotsford Drinking Water Resilience Project is an $84.4 million CAD direct response measure. The catastrophic floods in the Fraser Valley in November 2021 destroyed 85% of the local water supply system. Jointly funded by a $62 million CAD provincial government investment and the Abbotsford Mission Water Sewer Commission, the project shifts the community to a secure secondary regional water source. It includes drilling approximately 12 new vertical wells in Matsqui Prairie, along with a new water treatment plant and a dedicated pump station, directly connected to the existing regional network to serve over 165,000 residents in Abbotsford, Mission, and the Matsqui First Nation.
Saskatchewan's Lake Diefenbaker Irrigation Project is a multi-generational response to drought, with a total investment of $4 billion CAD aimed at doubling irrigated acreage to 500,000 acres. The first phase, the $1 billion CAD Westside Irrigation Rehabilitation Project (WIRP), is advancing, led by Prairie Engineering Partners (a joint venture of Stantec and MPE Engineering). Recent geotechnical work has expanded the rehabilitated land area from 90,000 acres to 100,000 acres, with the main channel capacity increased to 32 cubic meters per second. Economic analysis by KPMG indicates this phase will inject $12.9 billion CAD into GDP and create 80,000 jobs by boosting food processing, livestock, and crop diversity.
