In Metro Vancouver, water is collected from rainfall, snowmelt, creeks, and streams from the mountains near the Capilano, Seymour and Coquitlam watersheds. Our drinking water comes from one of the most pristine water sources in the world, and we are fortunate to have access to safe and reliable water each time we turn on the tap. Metro Vancouver and the City of Surrey closely monitor water quality throughout the system of reservoirs, treatment plants, pump stations, and water mains. Residents and businesses play an important role in protecting our drinking water by preventing backflow and contamination from other substances. The percentage of drinking water tests that meet water quality guidelines is a measure of how safe and clean our water supply is.
