Vancouver drinking water path

• Source & supply

  Capilano Reservoir

  Seymour Reservoir

  Coquitlam Reservoir

  City of Vancouver purchases wholesale treated water from Metro Vancouver (Greater Vancouver Water District) and operates the local distribution system of mains, reservoirs, and services within city limits.

  Source watersheds are closed to the public; alpine supplemental lakes in the Seymour supply area can be drawn in high summer demand.

• Treatment

  Seymour Capilano Filtration Plant

  Metro Vancouver plant treating Capilano and Seymour source water (filtration and UV); Canada’s largest drinking-water filtration plant.

  Coquitlam Water Treatment Plant

  Metro Vancouver plant treating Coquitlam source water with ozone, UV, and chlorine; typically unfiltered because of historically low turbidity.
