Gov. Code, § 65605

(a) Within 180 days of receipt of notification from a recycled water producer pursuant to Section 65604, the local agency shall adopt and enforce a recycled water ordinance pursuant to this article.

(b) The ordinance shall include, but not be limited to, provisions that do all of the following:

(1) State that it is the policy of the local agency that recycled water determined to be available pursuant to Section 13550 of the Water Code shall be used for nonpotable uses within the designated recycled water use area set forth by the local agency when the local agency determines that there is not an alternative higher or better use for the recycled water, its use is economically justified, and its use is financially and technically feasible for projects under consideration by the local agency.

(2) Designate the areas within the boundaries of the local agency that can or may in the future use recycled water, including, but not limited to, existing urban areas in lieu of potable water.

(3) Establish general rules and regulations governing the use and distribution of recycled water in accordance with applicable laws and regulations.

(4) Establish that the use of the recycled water is determined to be available pursuant to Section 13550 of the Water Code in new industrial, commercial, or residential subdivisions located within the designated recycled water use areas for which a tentative map or parcel map is required pursuant to Section 66426. These provisions shall require a separate plumbing system to serve nonpotable uses in the common areas of the subdivision, including, but not limited to, golf courses, parks, greenbelts, landscaped streets, and landscaped medians. The separate plumbing system to serve nonpotable uses shall be independent of the plumbing system provided to serve domestic, residential, and other potable water uses in the subdivision.

(5) Require that recycled water service shall not commence within the designated recycled water use area in any service area of a private utility, as defined in Section 1502 of the Public Utilities Code, or to any service area of a public agency retail water supplier that is not a local agency, as defined in subdivision (b) of Section 65603, except in accordance with a written agreement between the recycled water producer and the private utility or public agency retail water supplier that shall be made available in a timely manner by the recycled water producer to the local agency adopting the ordinance pursuant to this article.
