River on Tap: Where Does Our Water Come From?

Portola Valley is serviced by Cal Water. The Tuolumne River is the primary source of water and is stored in Hetch-Hetchy Reservoir and locally in Calavaras and Crystal Springs Reservoirs. San Francisco Public Utilities Commission (SFPUC) is the wholesaler to Cal Water. Local surface runoff and groundwater typically account for 10% of supply. The drought has reduced the availability of local surface water supplies. Expect continued guidance on water conservation from water retailers as the year progresses.
