Metro Vancouver's Greater Vancouver Water District (GVWD) and member municipalities work as partners to supply clean, safe drinking water to two million people and associated businesses. Metro Vancouver is also responsible for developing long range plans for managing the region’s three drinking water sources - Coquitlam, Capilano and Seymour.  

Metro is responsible for developing a Water Use Plan for the Seymour and Capilano Watersheds. This Water Use Plan is about how the reservoirs and dams are operated, how water is released from the reservoir and how it is allocated (as examples: drinking water, fisheries habitat, proposed power generation).
