GLOSSARY

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)).

Acre-Foot

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.
