Seismic reliability.  Delivery reliability. Water supply reliability.  People, businesses, and the economy in the Bay Area depend on a reliable water system.  That’s why the San Francisco Public Utilities Commission (SFPUC) is rapidly moving forward with the Water System Improvement Program (WSIP) to create long-lasting improvements to our aging water infrastructure and sustain the quality of life for our 2.5 million residential, commercial, and industrial customers in the San Francisco Bay Area.  Approximately one-third of delivered water goes to retail customers in San Francisco, while wholesale deliveries to 26 suburban agencies in Alameda, Santa Clara, and San Mateo counties comprise the other two-thirds. Built in the early to mid-1900s, many parts of the system are nearing the end of their working life, with crucial portions crossing over or near to three major earthquake faults. In 2002, SFPUC launched the $4.6 billion WSIP to repair, replace, and seismically upgrade the system’s deteriorating pipelines, tunnels, reservoirs, pump stations, storage tanks, and dams.  The program is funded by a bond measure that was approved by San Francisco voters in November 2002 and includes more than 80 projects throughout the service area – from San Francisco to the Central Valley – to be completed by the end of 2015.  The WSIP is one of the largest water infrastructure programs in the nation and the largest infrastructure program ever undertaken by the City of San Francisco. Reliability. Sustainability. Quality.  The WSIP objectives include: Improve the system to provide high-quality water that reliably meets all current and foreseeable local, State, and Federal requirements. Reduce vulnerability of the water system to damage from earthquakes. Increase system reliability to deliver water by providing the redundancy needed to accommodate outages. Provide improvements related to water supply/drought protection. Enhance sustainability through improvements that optimize protection of the natural and human environment. Keeping You Informed About WSIP. The WSIP website is dedicated to keeping customers and impacted stakeholders informed of project progress, answering your questions, and sharing business opportunities for the development and construction of the projects.
