Main Story
Temporary Water Source Change
As part of ongoing system improvements by Valley Water, the Rinconada Water Treatment Plant will undergo a temporary shutdown from 10/30/25 to 4/28/26. This allows for essential work including pipeline inspections and repairs, and other routine maintenance upgrades.
During this time, customers located on the West Side of SJW’s service area will receive water supplied from local groundwater and the Montevina Water Treatment Plant. No action is required—your water remains safe to drink and use. Please contact our Customer Service team at 408-279-7900 or customer.service@sjwater.com with any questions.

CA Passes Restrictions on Nonfunctional Turf for Commercial, Institutional and Industrial Customers
Nonfunctional turf (NFT) refers to lawns that grow around sidewalks, in front of businesses or other areas between the street and building entrances.
In a nutshell, California Law AB1572 prohibits the use of drinking water to irrigate NFT lawns which don’t serve a recreational or community purpose (i.e. a park or golf course).
Currently, many commercial, industrial, and institutional properties (including common areas managed by homeowner associations) have grass or a lawn that is no longer allowed per state law. For examples of what qualifies as NFT as well as additional resources, please head here.
