General Info

WaterThe San Francisco Public Utilities Commission manages a complex water supply system stretching from the Sierra to the City and featuring a complex series of reservoirs, tunnels, pipelines, and treatment systems. Two unique features of this system stand out: the drinking water provided is among the purest in the world; and the system for delivering that water is almost entirely gravity fed, requiring almost no fossil fuel consumption to move water from the mountains to your tap.The SFPUC, the third largest municipal utility in California, serves 2.5 million residential, commercial, and industrial customers in the Bay Area. Approximately one-third of delivered water goes to retail customers in San Francisco, while wholesale deliveries to 28 suburban agencies in Alameda, Santa Clara, and San Mateo counties comprise the other two-thirds of our deliveries.
