Public Reports and Data
- Recycled Water
- Recycled water means water which, as a result of treatment of waste, is suitable for a direct beneficial use or a controlled use that would not otherwise occur and is therefore considered a valuable resource. (Water Code § 13050(n)).
- It is defined by the volume of one acre of surface area to a depth of one foot. Since the acre is defined as a chain by a furlong (66 ft × 660 ft) the acre-foot is exactly 43,560 cubic feet. One acre-foot is taken to be the planned water usage of a suburban family household, annually.
- Indirect Potable Reuse
- The planned incorporation of recycled water into a raw water supply such as in potable water storage reservoirs or a groundwater aquifer, resulting in mixing and assimilation, thus providing an environmental buffer.
- Urban Uses
- Includes Golf Course Irrigation, Landscape Irrigation and Commercial and Industrial Uses.
- Other Uses
- Includes Geothermal Energy Production, Recreational Impoundment, Natural Systems Restoration, Surface Water Augmentation and all Other Uses.
