Our Drinking Water Supply - SCVWD

Santa Clara Valley Water District
Approximately 10% of the drinking water that we use in Mountain View is purchased from the Santa Clara Valley Water District.

About half the water sold by SCVWD originates hundreds of miles away and is delivered through the Sacramento-San Joaquin River Delta. The remaining supply comes from local rainfall, much of which is captured in SCVWD’s ten local reservoirs, and is released into local creeks and percolation ponds to replenish local groundwater aquifers and manage environmental needs, or is piped directly to one of three district water treatment plants.
 
In the late 1920s, serious groundwater overdraft and significant land surface subsidence (totaling approximately 13 feet in northern San José) led to the formation of the SCVWD as Santa Clara Valley’s groundwater management agency. The first function of the SCVWD in 1929 was to develop a reliable water supply, build reservoirs to store water, and recharge the underground aquifer to halt subsidence.

Continued growth throughout Santa Clara County and the associated need for additional water led to the purchase of imported water supplies in the 1960s and 1980s. In 1965 SCVWD began receiving deliveries of water imported from the California Department of Water Resource’s State Water Project. To further increase the reliability of water in the 1980s, SCVWD contracted with the United States Bureau of Reclamation for delivery of water from the Central Valley Project. Water purchased from the State Water Project and the Central Valley Project is diverted from the Sacramento-San Joaquin River Delta.
