The San Francisco Public Utilities Commission (SFPUC) is a public agency of the City and County of San Francisco that provides water, wastewater, and electric power services to the city and an additional 1.9 million customers within three San Francisco Bay Area counties.Functions
The SFPUC manages a complex water supply system consisting of reservoirs, tunnels, pipelines and treatment facilities and is the third largest municipal utility agency in California. The SFPUC protects its watershed properties with security utility trucks and fire apparatus painted white over green. The SFPUC provides fresh water from Hetch Hetchy Reservoir to 2.7 million customers for residential, commercial, and industrial uses. Near one-third of its delivered water is sent to customers within San Francisco, while the remaining two-thirds is sent to Alameda, San Mateo, and Santa Clara counties.
Since its creation in February 2005, the SFPUC Power Enterprise Division has supplied power to many city facilities including Muni, San Francisco International Airport as well as the Modesto and Turlock Irrigation districts. The SFPUC also administers and operates CleanPowerSF, a Community Choice Aggregation program within the guidelines of California State law. The SFPUC is also the water, full retail electricity service, and wastewater utility for occupants of Treasure Island and Yerba Buena Island.
The SFPUC manages an extensive wastewater system that collects, conveys, and provides secondary treatment to combined sewage flows (both stormwater and sewage) within the City & County of San Francisco before discharging it into the San Francisco Bay  and the Pacific Ocean.  The Southeast Water Pollution Control Plant handles about 80% of the city's wastewater, while the Oceanside Water Pollution Control Plant handles the remaining 20%.  A third facility, the North Point Wet-Weather Facility, only operates during wet weather to provide primary treatment to combined sewage prior to discharging to the San Francisco Bay.
