The Santa Clara Valley Water District’s Rinconada Water Treatment Plant, which provides treated water to parts of SJW's service area, is undergoing planned construction and maintenance work from March 12th through March 17, 2018. During this period, SJW will deliver groundwater to customers in the communities located south of Stevens Creek and west of Highways 880 & 17.

Groundwater, while typically “harder” than the supply normally provided to SJW by the Santa Clara Valley Water District, meets or exceeds all applicable drinking water regulations.  Click here for more information about water quality.

For additional information and questions on hard water please call (408) 279-7900.
