Our water comes from rainfall and snowmelt in the mountainous areas called watersheds, north of the cities. There are three watersheds: Capilano, Seymour and Coquitlam – which together cover an area 150 times the size of Stanley Park. The watersheds are closed to public access, protecting our water supply from human disturbance and providing some of the best drinking water in the world.
The rainfall and snowmelt flows into large collection lakes, called reservoirs. Water is stored in these reservoirs, then treated and distributed to the cities, which deliver it to your tap.
