(1) The Water Recycling Law generally provides for the use of recycled water.

This bill would, for the purposes of the above provision, redefine "recycled water" and provide that water discharged from a decorative body of water during storm events is not to be considered an unauthorized discharge if recycled water was used to restore levels due to evaporation.
(2) Existing law regulating the use of recycled water prohibits the use of prescribed potable water by state and local agencies for any nonpotable uses, including cemeteries, golf courses, parks, and highway landscaped areas if prescribed recycled water is available, and deems use of the recycled water in lieu of the potable water to constitute a reasonable beneficial use of that water.
The bill would provide that incidental amounts of spray, mist, or runoff are to be permitted to enter outdoor eating areas of parks and open spaces when irrigated with disinfected tertiary treated recycled water that complies with a specified regulation regarding irrigation.
(3) Existing law authorizes any public agency, including a state agency, city, county, city and county, district, or any other political subdivision of the state, to require the use of recycled water for irrigation of residential landscaping, as specified.
The bill would provide that outdoor landscape irrigation of common areas that does not enter the boundaries of a residence is not to be considered a part of the same premises as an individual residence and is not to be considered a dual-plumbed system. The bill would require recycled water used for this purpose to comply with specified water quality and cost conditions.
(4) Existing law authorizes any public agency, including a state agency, city, county, city and county, district, or any other political subdivision of the state, to require the use of recycled water for toilet and urinal flushing in structures, as specified. Existing law defines "structures" for the purposes of these provisions.
This bill would include food handling and processing facilities as part of the definition of "structures." The bill would authorize the use of recycled water for toilet or urinal flushing or outdoor irrigation in and around food handling or processing facilities, commercial, institutional, and industrial buildings, and cafeterias, provided the recycled water does not enter the room where food handling or processing occurs, as specified.
