Water Use Efficiency

About the Department

Southern California is a semi-arid region and is largely dependent upon imported water supplies. A growing population, climate change, environmental concerns, and other factors in other parts of the state and in the western United States, make the region highly susceptible to water supply reliability issues. Careful water management that includes active water use efficiency measures not only in times of drought, but at all times, is essential to ensure a reliable minimum supply of water to meet current and future water supply needs.

The District finds and determines that because of the prevailing water conditions in the state, it is necessary and appropriate for the District to adopt, implement, and encourage participation in water use efficiency programs to ensure that there is sufficient water for human consumption, sanitation, and fire protection.

Our Water Use Efficiency Department is committed to achieving long-term water use efficiency in all water use sectors. Our vision is to follow a bold and thorough approach that focuses on sustainability through education, leak detection, and innovated programs, all while providing high-quality water to our customers and communities in a prudent and sustainable manner.
