The Board of Supervisors finds that:
(a) All California water users are responsible for making effective use of the available water resources.
(b) The development of alternate water source systems will assist in meeting future water requirements of the City and lessen the impacts of new developments on the City's sewer system.
(c) Establishing a regulatory structure that provides administrative efficiency and a streamlined project approval process will assist developers who opt to design, install, operate, and maintain alternate water source systems.
(d) Adoption of Article 12C by the Board of Supervisors and adoption of rules and regulations by the Department of Public Health will help achieve the City's goals for water supply use and preservation by:
(1) Promoting the values and benefits of non-potable water use while recognizing the need to invest water and other resources as efficiently as possible;
(2) Encouraging the use of non-potable water for non-potable applications; and
(3) Replacing potable water use for toilet and urinal flushing and irrigation to the maximum extent possible with alternative water sources.
(e) It shall be City policy that within five years of the effective date of Ordinance No. 109-15,1
adding this subsection (e) to Article 12C, the City shall use only non-potable water for the purpose of irrigating and cleaning parks, streets, and other public spaces. Within two years of the effective date of that ordinance, the City Administrator, in consultation as appropriate with other City departments, boards, and commissions, including, among others, the Recreation and Park Department, Department of Public Works, Port of San Francisco, San Francisco International Airport, Division of Real Estate, and Capital Planning Committee, shall study what will be required to accomplish this policy, including associated costs, and report the results of the study to the Mayor and Board of Supervisors. Upon receiving this study, the Board of Supervisors intends to evaluate any changes to the law and Capital Plan needed to implement this policy.
(f) The General Manager of the San Francisco Public Utilities Commission shall submit a report to the Board of Supervisors by December 31, 2021, evaluating the challenges of, and opportunities for requiring the construction, operation and maintenance of Non-potable District Systems at District Development Projects. The report shall also identify the opportunities for the expansion of water heating systems including, but not limited to thermal solar hot water preheating systems, graywater preheating systems, wastewater heat recovery systems, and geo-thermal hot water preheating systems.
(g) In order to further determine opportunities to maximize and expand the use of nonpotable sources of water, the General Manager of the San Francisco Public Utilities Commission shall submit to the Board of Supervisors by June 1, 2022, a report evaluating opportunities to develop a recycled water and purified water supply for San Francisco.
(h) The General Manager of the San Francisco Public Utilities Commission shall submit a report to the Board of Supervisors by December 31, 2022, identifying the opportunities for biogas utilization and energy recovery from the San Francisco Public Utilities Commission’s Biosolids Digester Facilities Project.
