History of the SWP
• 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.

History continued• 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.
