San Francisco Public Utilities Commission — Stay up to date on everything water, clean energy, & wastewater.

Report any water, power, or sewer issues to San Francisco 311. Water

The SFPUC delivers drinking water from the Hetch Hetchy Regional Water System to 2.6 million people. 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 minimal fossil fuel consumption. The Water Enterprise also manages the City's Auxiliary Water Supply System for firefighting preparedness. Power

The Hetch Hetchy Power System's hydroelectric powerhouses, solar installations and biogas units generate about 1.7 billion kilowatt hours of clean, renewable and reliable energy annually for vital City services. We are continuously researching, developing, and installing new electricity-generating resources to provide clean power for our customers. San Francisco will be one of the first cities in the nation to offer residents and businesses the opportunity to choose a 100% renewable energy supply with our CleanPowerSF program. Our diverse, renewable energy portfolio makes us one of the cleanest energy utilities in California. Sewer

The Wastewater Enterprise provides innovative resource re-use initiatives such as the Biofuel/Alternative Energy Program. We generate bio-energy as a byproduct of processing fats, oils, and greases that can clog our combined sewer system. The system collects, transmits, treats and discharges about 9.2 million cubic feet of sanitary runoff per year. We protect the public health and environmental safety of the San Francisco Bay and Pacific Ocean.

The San Francisco Public Utilities Commission selected a Jacobs-PCL joint venture for a $192.8-million contract to design and provide preconstruction services for a $1.45-billion nutrient reduction project at the Southeast Treatment Plant.

The progressive design-build project, with an estimated $600 million in direct construction costs, will upgrade treatment systems to reduce nutrient discharges into San Francisco Bay.

It is also part of SFPUC’s planned $5-billion modernization of the 75-year-old plant, which handles nearly 80% of the city’s wastewater and stormwater.
