The Board of Supervisors finds that:
(a) Demand management measures, including feasible, cost effective conservation, are a proven method of reducing water demand in urban areas.
(b) The application of proven water conservation measures will allow San Francisco's economy and population to prosper without placing additional demands on this valuable resource. Retrofitting water using devices such as water efficient showerheads, faucet aerators, and water closets is one of the most cost effective ways of reducing the City's potable water use.
(c) As a signatory to the California Urban Water Conservation Council Memorandum of Understanding Regarding Urban Water Conservation, the San Francisco Public Utilities Commission has agreed to actively promote the replacement of high water volume water closets and showerheads, among other water using devices, with more efficient models in San Francisco. The purpose of this section is to reduce demand for potable water within the City and County of San Francisco by establishing water efficiency standards for plumbing fixtures. Water saved from these programs will help to ensure a reliable water supply for customers both within and outside of San Francisco. This ordinance is part of a continuing program to achieve the City's goal of reducing water consumption in all residential, commercial, industrial and municipal buildings in the City and County of San Francisco.
