San Diego County Continues Efficient Water-Use Practices
Over the last 20 years, total per capita water use in the Water Authority’s service area dropped from almost 220 gallons per capita per day (gpcd) to less than 135 gpcd in FY 2022. During this timeframe, potable water use fell by approximately 30 percent, even though the region’s population grew by almost 20 percent.
Since 1991, the Water Authority’s water-use efficiency programs and initiatives cumulatively conserved more than 1 million acre-feet of water. These savings were achieved through various measures that included, incentives on water-efficient devices, legislative efforts, and outreach programs.Water-Use Efficiency Fact Sheet
