Water services are provided to residents and businesses in the City of Santa Clara by the Water Utility. The Water System consists of approximately 335 miles of water mains, 26 wells and 7 storage tanks with approximately 28.8 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 26 wells that tap the underground aquifers and make up about 62% of the City's potable water supply. A water recharge program administered by the SCVWD from local reservoirs and imported water enhances the dependability of the underground aquifer. The remaining water is supplied by water imported from the two wholesale water agencies.
For certain approved non-potable uses, recycled water from the San Jose/Santa Clara Regional Wastewater Facility's South Bay Recycled Water facility is used. This is highly treated water delivered through separate pipelines. This source makes up about 16% of the water sales in the City of Santa Clara. Recycled water offsets the use of potable sources in drought-prone California and is a reliable source for conservation of potable sources.
