San Diego County Embraces Water-Use Efficiencies
Per capita water use in the Water Authority’s service area has fallen from more than 200 gallons per person/day to less than 130 gpcd over the past decade. In 2020, total regional use of potable water was about 30 percent less than it was in 1990, even though the regional population grew by 35 percent.
Since 1991, the Water Authority’s water-use efficiency programs and initiatives cumulatively have conserved more than 1 million acre-feet of water. These savings have been achieved through measures that include incentives on water-efficient devices, legislative efforts, and outreach programs.Water-Use Effeciency Fact Sheet
Policy & Legislation

The principles provide high-level, strategic direction on the prioritization, development and implementation of water-use efficiency programs and initiatives.
Water-Use Data Trends
Total potable water use excludes reclaimed water. In order to provide for a meaningful comparison, 2007 M&I water use was adjusted for 2009-2011 IAWP and SAWR opt-out volumes that convert to M&I water use.
