The C. W. “Bill” Jones Pumping Plant lifts water from the Sacramento-San Joaquin Delta into the Delta-Mendota Canal. The plant, located about 12 miles northwest of Tracy, is essential for supplying agricultural, urban, and wildlife water to parts of the Delta and to the San Luis and San Felipe Units of the Central Valley Project.
The major portion of the water supplied to the Jones Pumping Plant pumps is derived from northern Central Valley Project reservoirs. The supply is routed across the Sacramento-San Joaquin Delta from the Sacramento River to the Old River through the Delta Cross Channel and the natural channels of the Delta. The intake to the pumps is about 9 miles northwest of Tracy.
Six pumps, each powered by a 22,500-horse-power electric motor, lift Delta waters about 200 feet from the intake through three discharge pipes, which then carry it up a distance of about 1 mile to the Delta-Mendota Canal. Power to run each pump is generated by CVP facilities.
The total capacity of the plant is about 5,200 cubic feet per second, each unit with a pumping capacity between 850 cfs and 1,050 cfs.
