Summary

The City of Santa Clara purchases water from SF RWS and SCVWD. Two SF RWS turnouts off BDPL 3 and 4 supply the Northside tank and booster station, which distributes water to the northernmost pressure zone of the City. Water from SCVWD is delivered to the southwest portion of the City through the Santa Clara Distributary.

Water from 19 active wells meet current drinking water standards without treatment and produce over half of the City’s water supply.

The City also operates a recycled water system, which is part of the South Bay Water Recycling system. Tertiary treated effluent from the jointly owned San Jose-Santa Clara Regional Wastewater Facility (RWF) is available for landscape irrigation, commercial dual plumbing and certain industrial uses, distributed within Santa Clara by about 33 miles of pipeline.
