The Water System Improvement Program (WSIP) is a $4.8 billion dollar, multi-year capital program to upgrade the SFPUC's regional and local water systems. The program will deliver capital improvements that enhance the SFPUC's ability to provide reliable, affordable, high quality drinking water in an environmentally sustainable manner to 2.6 million people in the greater Bay Area. The program consists of 83 projects - 35 local projects located within San Francisco and 48 regional projects, spread over seven counties from the Sierra foothills to San Francisco.
Currently, the WSIP is approximately 90% complete with construction finished on 34 local projects valued at $290 million and 32 regional projects valued at $1 billion along the landmark Hetch Hetchy Regional Water System to ensure reliable water delivery to customers.
The program is funded by a bond measure that was approved by San Francisco voters in November 2002 and will be paid for by both retail customers in San Francisco and 26 wholesale customers that serve Alameda, San Mateo and Santa Clara counties.
