Drinking Water System
Poway operates a modern water treatment and distribution system. The heart of the city's water infrastructure begins with the importation of water from both the Colorado River and Northern California. Lake Poway serves as a storage reservoir and is able to store over 1 billion gallons of water at one time. Water flows through the Lester J. Berglund Water Treatment Plant, where approximately 3 billion gallons of drinking water are treated every year for the citizens of Poway. Once treated, the drinking water enters a system of pipes, pump stations, reservoirs for delivery to customer's homes and businesses.
