A multi-faceted system of 34 storage reservoirs and lakes, pipelines and canals that allows our member agencies to capture, store and deliver clean, cost-effective water supplies that:
Serve drinking water to 2/3 of California's residents
Irrigate more than 750,000 acres of farmland
Directly sustain more than $400 billion of the statewide economy
The vast majority of the state’s water supplies come from the high Sierra Nevada Mountains where rainfall and snowmelt fill rivers and tributaries that travel toward the Sacramento-San Joaquin Delta. The SWP captures and stores a small share of these supplies, which are then delivered through 700 miles of canals and pipelines for use throughout the state.
The Delta is home to more than 700 native species and serves as California's primary freshwater supply hub - the heart of the State Water Project and its federal counterpart, the Central Valley Project, as well as many farms and landowners within the Delta region.
California must reinvest in its water future. The state's outdated water delivery system tasked with protecting and moving supplies through the Delta is no longer fit for the job.
Earthquakes and rising sea levels pose a constant threat to freshwater
Crumbling infrastructure coupled with strict environmental restrictions prevent water managers from capturing needed rainfall when it's abundent
The environment still deteriorates
The proposed solution, California WaterFix and the parallel California EcoRestore, aim to protect the Delta and improve water reliability for all who depend on this critical supply. The centerpiece of the project is the construction of two pipelines to move water under - rather than through - the fragile Delta.
Secure California's water supply and provide safe, reliable water throughout the state.
Provide water agencies the flexibility to capture and store more water when supplies are available, enabling the state to better prepare and minimize the impacts of future droughts.
Built to withstand earthquakes and protect this critical water supply from potential disruptions caused by climate change.
Restore the natural direction of Delta river flows by moving the primary diversion point from the South Delta to the North Delta, benefiting threatened fish species.
California WaterFix was developed over nearly a decade of extensive expert review, planning, and scientific and environmental analysis. Public water agencies that purchase water from the State Water Project and Central Valley Project would fund the construction, ongoing operations and any environmental mitigation associated with the project.

Every day, the SWP generates and uses one of the cleanest power supplies in the state. California's fourth largest energy producer, the SWP is well ahead of every major California utility on the pathway to the state's 2050 carbon goals.
