Metro Vancouver is proposing to double its capacity to access, treat, and distribute water from Coquitlam Lake, the largest of the three drinking water sources, through the construction of the Coquitlam Lake Water Supply Project. Planning is currently underway for the design of a new water intake, a water supply tunnel, and water treatment facilities.
A recently completed long-term water supply planning study shows there will be enough water in Coquitlam Lake in the mid-2030s to supply the region, but by then new infrastructure will be needed to access that water and meet summer demand.
The Coquitlam Lake Water Supply Project is currently in the Project Definition phase which will help determine the scope of work including the intake location, tunnel alignment, and treatment technology. Construction is expected to begin in the late 2020s, with completion targeted for the late 2030s.
Once complete, this significant infrastructure project will help meet the region’s growing need for drinking water well into the next half century, provide resiliency to address the anticipated impacts of climate change, and provide increased operational flexibility to the existing infrastructure.
