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 295 miles of water mains, 27 wells and seven storage tanks with more than 27 million gallons of water capacity.

Sources available to the City include an extensive underground aquifer (tapped by the wells) and imported water supplies delivered by two wholesale water agencies: The Santa Clara Valley Water District (SCVWD) and San Francisco Hetch-Hetchy System.

About 34% of the City's water comes from these imported treated water supplies. About 11% of the City's water is recycled water used for irrigation. This is highly treated water delivered through a separate piping system from the Water Pollution Control Plant.

A water recharge program administered by SCVWD from local reservoirs and imported water enhances the dependability of the underground aquifer.

 
A Portion of the City Receives Fluoridated Water

The City of Santa Clara has three sources of drinking water, groundwater, and water purchased from the Santa Clara Valley water district and the San Francisco Water Department. In late Fall 2005, the San Francisco Water Department began to supplement the amount of fluoride already present so that drinking water they provide will meet the level of fluoride recommended by the California Department of Health Services. Only the customers in the section of the City of Santa Clara that is served with water originating from the San Francisco Water Department’s Hetch Hetchy system receive fluoridated water service; see map below for details. Other water customers in the City receive water from other sources, such as City-owned wells and another wholesaler.

If you are in the area that receives fluoridated water at least part of the time, please note that:

  • There will be no change in the taste, odor or appearance of your water.
  • You and your children no longer need to take fluoride supplements such as pills or drops. Dosage in the fluoridated water delivered to your home may not be optimal. Check with your physician or dentist.
  • Fluoridated water benefits people of all ages.

For more information about fluoride, please see Fluoride Facts and Fluoride Frequently Asked Questions.
