Water Portfolio, Customers and Water Use
The 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 26 of the 27 wholesale customers and
coordinates their water conservation, supply
and recycling activities.
During FY 2017-18, the SFPUC delivered approximately
197 million gallons per day (mgd) on average to
its wholesale and retail customers. Wholesale
customers received 129  mgd, San  Francisco retail
customers received approximately 64 mgd and retail
customers outside of San Francisco received 4 mgd,
totaling 68 mgd across the retail service area.
uses 64  mgd. In FY 2017-18, San  Francisco retail
customers’ gross per capita use was approximately
74 gallons per day and the residential per capita
water use was about 42 gallons per day. While this
water use was among the lowest in the State, the
SFPUC remains committed to comprehensive water
conservation efforts.
ONEWATERSF
OneWaterSF is a framework for how the SFPUC
does business; it provides a vision for how we can
better adapt to future challenges. It is an integrated
planning and implementation approach to managing
finite resources for long-term resiliency and
reliability. With OneWaterSF, the SFPUC recognizes
the potential of all the resources within our system.
OneWaterSF allows us to look more holistically at
our system for efficiencies, project synergies and
opportunities to harness clean energy, and to match
the right water to the right use.
In 2016, the SFPUC laid out the Vision and Guiding
Principles for OneWaterSF and created the
OneWaterSF Working Group, which includes staff
San Francisco retail customers’ water conservation
from throughout the SFPUC. This year, we continued
efforts, supported in part by incentives and
to accomplish many of our initial goals driven
assistance from the SFPUC, have helped San
