Water services are provided to residents and businesses in the City of Santa Clara by the Water Utility. The Water System consists of more than 315 miles of water mains, 27 wells and 7 storage tanks with more than 27 million gallons of water capacity.
Sources available to the City include an extensive local underground aquifer and imported water supplies delivered by two wholesale water agencies: the Santa Clara Valley Water District (SCVWD) and the San Francisco Hetch Hetchy system.
The City operates 27 wells that tap the underground aquifers and make up about 62% of the City's water supply. A water recharge program administered by the SCVWD from local reservoirs and imported water enhances the dependability of the underground aquifer.
An additional 25% is supplied by water imported from the two wholesale water agencies.
A third source of water available to the City for irrigation purposes is recycled water from the San Jose/Santa Clara Water Pollution Control Plant's South Bay Recycled Water facility. This is highly treated water delivered through separate pipelines. This source makes up about 13% of the water used in the City of Santa Clara. Recycled water offsets the use of potable sources in drought-prone California and is a reliable source for irrigation for conservation of potable sources.
