How the water and sewer system works

Vancouver has 1,450 km of water pipes, and 2,800 km of sewer pipes.

Vancouver's water and sewer system is a complex network of pipes that delivers 295 million litres per day of fresh, potable water into Vancouver homes and businesses, and removes excess water and sewage for treatment.

The City also builds on the latest environmental studies to develop systems to collect rainwater and stormwater runoff from buildings, roads, and parking lots, to carry into the local waterways, like Burrard Inlet and the Fraser River.
