Water Resources Division Annual Report FY 2016-2017 | Page 4

The Hetch Hetchy Regional Water System is a public asset that delivers high-quality drinking water to 2.7 million residents and businesses in the Bay Area . The system collects water from the Tuolumne River in the Sierra Nevada and from protected local watersheds in the East Bay and on the Peninsula . The SFPUC delivers water to 27 wholesale customers in Alameda , Santa Clara and San Mateo counties and provides direct retail water service to customers in San Francisco and some customers outside of San Francisco . The Bay Area Water Supply & Conservation Agency ( BAWSCA ) represents the interests of 26 of the 27 wholesale customers and also coordinates their water conservation , supply and recycling activities .

During FY 2016-17 , the SFPUC delivered approximately 181 million gallons per day ( mgd ) on average to its wholesale and retail customers . Wholesale customers received 116 mgd , San Francisco retail customers received approximately 62 mgd and retail customers outside of San Francisco received 3 mgd .

San Francisco retail customers ’ water conservation efforts – supported in part by incentives and assistance from the SFPUC – have helped San Francisco reduce total water demand over the last two decades despite population growth . In FY 2016-17 , San Francisco retail customers ’ gross per capita use was approximately 72 gallons per day and the residential per capita water use was about 41 gallons per day . While this water use was among the lowest in the State , the SFPUC remains committed to comprehensive water conservation efforts .
