Constructing a new treatment facility to ensure a safe and reliable water supply to surrounding communities

Capilano Lake reservoir is the source for chlorinated, unfiltered water to Metro Vancouver. Periodically, turbidity in the lake is too high to provide potable water, so it was necessary to construct new treatment facilities to ensure a reliable and safe supply to this community of over 2,000,000 people. The original plan was to build two new facilities. Instead, our team proposed pumping lake water to the new Seymour Capilano Filtration Plant, eliminating the significant costs and impacts of a second treatment facility.

The 1,080 MLD pump station transfers unfiltered lake water through a 7 kilometer long, 3.6 meter diameter tunnel to the plant. Potable water is then returned by gravity via a second similar tunnel and passes through an energy recovery facility before reconnecting to the existing distribution system. The station is made up of eight, 2,000 HP pump and motor sets and 0.5 kilometers of complex, large bore internal piping up to 2.3 meters in diameter.

The significant size of the pumps required special attention to motor cooling, vibration, and hydraulic transients. Seismic considerations and constructability challenges on up-slopes required self-supporting piping designed to withstand the loss of soil support during significant rainfall events.

The site is located in a regional park, so we focused on reducing environmental and community impacts while ensuring public access was not impacted.
