The Water System Improvement Program (WSIP) includes 87 projects that will benefit every resident and business receiving water from the Hetch Hetchy Regional Water System. Because the system crosses three of the nation's most active earthquake faults, the WSIP is first and foremost a program that will enhance our system's seismic reliability to ensure a safe and reliable water system for 2.7 million customers in Alameda, Santa Clara, San Mateo, and San Francisco counties.

The following WSIP projects are currently in pre-construction or construction:

ACRPAlameda Creek Recapture Project
