SFPUC - Water Enterprise
The San Francisco Public Utilities Commission (SFPUC) provides and distributes water to 2.6 million customers, treats wastewater, and supplies electric power to operate Muni streetcars and electric buses, street and traffic lights, and municipal buildings. The amount of facilities and infrastructure it takes to accomplish its mission is vast, including 16 dams, 25 reservoirs, eight water tanks, three water treatment plants, 933 miles of sewers, 160 miles of transmission lines, and over 150 miles of pipelines. This complex network of infrastructure is managed by three utility enterprises within the SFPUC: Water, Wastewater, and Hetch Hetchy Water and Power.
