History of the SWP Its main purpose is to store water and distribute it to 29 urban and agricultural water suppliers Its main purpose is to store water and distribute it to 29 urban and agricultural water suppliers Of the contracted water supply, 70 percent goes to urban users and 30 percent goes to agricultural users. Of the contracted water supply, 70 percent goes to urban users and 30 percent goes to agricultural users.

History continued The Project includes: The Project includes: – 32 storage facilities – reservoirs and lakes – 17 pumping plants – 3 pumping-generating plants – 5 hydroelectric power plants – 660 miles of open canals and pipelines. The Project provides supplemental water to approximately 20 million Californians and about 660,000 acres of irrigated farmland.
