EXECUTIVE SUMMARY
BAWSCA is a special district created by the legislature in 2002. BAWSCA provides regional water
reliability planning and conservation programming for the benefit of its 26 member agencies
that purchase wholesale water supplies from the San Francisco Public Utilities Commission
(SFPUC).1 Collectively, the BAWSCA member agencies (or wholesale water customers) deliver
water to over 1.8 million residents and nearly 40,000 commercial, industrial and institutional
accounts in Alameda, San Mateo and Santa Clara Counties.
BAWSCA also represents the collective interests of these wholesale water customers on all
significant technical, financial, and policy matters related to the operation and improvement of
the SFPUC’s Regional Water System. As a member of BAWSCA, the City of Palo Alto is formally
represented on the BAWSCA Board of Directors on matters involving decision-making, policy
setting and issues of interest to the BAWSCA members.
BAWSCA’s CEO/General Manager, Nicole Sandkulla will present to the UAC. Ms. Sandkulla will
provide an overview of BAWSCA and its goals and activities on behalf of its member agencies,
