6 <br />Orange Water and Sewer Authority <br />Water Conservation Standards <br />(Approved 1Vlarch 26, 2009) <br />Article I -Purpose and Definitions <br />L A. Purpose <br />These Water Conservation Standards are enacted by the Orange Water and Sewer Authority <br />(OWASA) for the purposes of: <br />Reducing the rate of increase in overall water use through year-round water conservation <br />practices that will help maximize the community's existing and planned .water supply <br />sources and help reduce seasonal peak day demands that result in the need for costly <br />expansion of water treatment, storage, and transmission facilities. Such year-round <br />practices shall include: <br />a. Reducing indoor water waste by encouraging the installation and maintenance of <br />ultra-low flow toilets, faucet aerators, low-flow showerheads and similar devices, <br />as well as other creative and commonsense indoor conservation practices. <br />b. Reducing irrigation and irrigation-related. water waste without sacrificing <br />landscape quality through the cultivation of lower water use plants; improved <br />landscape design and planting practices; more efficient watering practices; and <br />improved irrigation system design and maintenance. <br />c. Increasing the use of non-potable water, as permitted by appropriate public health <br />regulations, for irrigation and other uses that do not require water of potable <br />quality. <br />2. Providing an orderly process for reducing community-wide water demands during <br />periods of drought or other naturally occurring causes of water shortages. <br />3. Providing an orderly process for reducing community-wide water demands during <br />periods of water shortages due to natural disaster (other than drought), major OWASA <br />facilities failure, or other unexpected and sudden loss of water supply, treatment, or <br />distribution capacity that constitutes a water supply emergency. <br />L B. Definitions <br />For the purpose of these Standards, the following definitions shall apply unless the context <br />clearly indicates or requires a different meaning. <br />AUTOMATIC CONTROLLER A mechanical or electronic device capable of operating <br />an irrigation system and its component valve stations according to apre-determined <br />schedule of irrigation frequency and duration. <br />
