Summary
The City of San Bruno water supply comes from three different sources – surface water purchased from San Francisco Public Utilities Commission (SFPUC), surface water purchased from North Coast County Water District (NCCWD), and ground water produced from the City’s wells. Historically, approximately half of the City’s total water supply came from purchased surface water and remaining supply was produced from the City’s groundwater wells. As of 2016, San Bruno has increased its use of surface water supplies during wet and normal years in accordance with the regional Groundwater Storage and Recovery (GSR) project. The City now receives approximately 90 percent of its supplies from surface water in wet and normal years.
The San Bruno Water system consists of 5 surface water supply turnouts, 4 active groundwater wells, 8 storage tanks, 13 pressure zones, 8 booster pump stations, 31 pressure regulating stations, most of which are equipped with pressure reducing valves that regulate water from high pressure zones to lower pressure zones and approximately 116 miles of water mains ranging in sizes from 2 to 18 inches diameter.
