Beginning Tuesday, September 21, 2021, Valley Water will be taking Rinconada Water Treatment Plant out of service to make repairs to a leak on the raw water supply pipe. Anticipated completion of the repair work is Friday, September 24, 2021.  While the Rinconada Water Treatment plant is off-line, SJW will use local groundwater supplies to meet system demands. 

This affects San Jose Water customers that are located west of Highway 17 and includes in the communities of Campbell, Los Gatos, Monte Sereno, Saratoga and Cupertino. 

This change in source water may result in some aesthetic changes in the water served to customers. Groundwater disinfected with free chlorine has an earthier smell than chloraminated surface water, and free chlorine is more readily detectable in taste and smell than chloramine. Additionally, groundwater has higher hardness, meaning you may notice scaling of white calcium deposits and spotting on dishware.

Please know that both sources meet all drinking water standards and are safe to drink. For more information on hard water, visit our Water FAQs page at sjwater.com/waterfaqs or call us at (408) 279-7900.
