Practicing OneWaterSF
The SFPUC is fortunate to have a Regional Water System (RWS) that provides extremely high quality water and greenhouse gas (GHG) free
electricity at a low energy cost. At the same time, we have developed a strong Local Water Program, which includes groundwater, recycled
water, and conservation, to help diversify and stretch the RWS supplies from the Hetch Hetchy, Alameda, and San Mateo watersheds. We also
operate a sewer system that protects public health and water quality of the San Francisco Bay and the Pacific Ocean by reliably collecting
and treating sewage and street runoff.
When we look at the entirety of our water and sewer systems, energy is both consumed and generated at various points. While the RWS
itself is almost entirely gravity fed and does not consume fossil fuels, we do consume energy at our three water treatment facilities, at our
four wastewater treatment plants, and at numerous water and wastewater pump stations. We generate 385 megawatts of GHG-free power at
three hydroelectric powerhouses in the Sierra Nevada, and also generate renewable clean power at other key points in the system including
solar panel arrays installed on various facilities and through biogas generation at our wastewater treatment plants. This generation and
consumption of energy throughout the water and sewer systems, as well as the potential opportunities within the system to further develop
clean power, makes energy a key element of OneWaterSF.
