About the City's Water Supplies
The City of Palo Alto's primary source of water is the San Francisco Regional Water System (SF RWS) operated by the San Francisco Public Utilities Commission (SFPUC). In most years, SFPUC provides 100% of Palo Alto’s potable water supply.
To improve the capacity of the local water distribution system in the event of an emergency, the City initiated the Emergency Water Supply and Storage Project. The Project included the rehabilitation of 5 existing wells, construction of 3 new wells, and construction of a new 2.5 million gallon emergency water storage reservoir. Palo Alto now has adequate storage and pumping capacity to provide emergency back up during an interruption of SF RWS service. The wells may also be available to meet limited dry year requirements.
Palo Alto replaces potable water with recycled water to irrigate a golf course and a city park, to fill a duck pond, and provide some uses at the water quality control plant. Recycled water use that does not replace potable water includes the Emily Renzel Marsh enhancement project and additional process uses at the water quality control plant.
Palo Alto produces an Urban Water Management Plan every five years, which details our water supplies and conservation efforts. You can view the latest report at cityofpaloalto.org/UWMP. The City also publishes a Consumer Confidence Report on water quality conditions every year.
