Stockton, CA Water Use Rules: Recycled Water Rules (2026)

010 defines "recycled water" as water from the City of Stockton Regional Wastewater Control Facility, supplied from designated hydrants under a permit from the State Regional Water Quality Control Board, and separately defines "reclaimed water" as the recaptured soap/water solution reused at a non-self-service commercial car wash. 030. 1, potable water from any fire hydrant is banned May 1 through November 1 except for fire suppression or by the water agency "when alternate water sources or reclaimed water sources are available"; absent an alternate or recycled source, hydrant use needs a joint Fire Department/water agency permit.

4 requires non-self-service commercial car washes to reclaim their soap/water solution; if a reclaimed system cannot be installed, the operator must submit a Director-approved plan to cut water use by at least 20 percent compared with the same month the prior year for comparable business volume, or supply comparable baseline data if there is no usage history. 7 bars potable water for dust control except for public health or safety purposes, directing that reclaimed, recycled or other nonpotable water be used instead so long as it is not wasted.

B requires new subdivision water systems to be designed to State and AWWA standards "including the use of nonpotable/recycled water systems, as appropriate," alongside City standard specifications and State Department of Health Services requirements. None of these provisions force existing homes or most businesses to install recycled-water plumbing; recycled water use is enabled at specific use points, not mandated citywide.
