Since 1991, San Diego County ratepayers have conserved more than 1 million acre-feet of water, and per capita potable water use in the region decreased nearly 60 percent between fiscal years 1990 and 2019, according to the San Diego County Water Authority.
The findings are part of the Water Authority’s draft 2020 Urban Water Management Plan, which was released Monday for public review.
The report concludes that as a result of conservation and billions of dollars in infrastructure, San Diego should have sufficient water supplies through 2045.
“Thanks to decades of regional investments (and conservation) the draft plan shows that we don’t need to secure more regional supply sources for the foreseeable future,” Water Authority general manager Sandra Kerl said in a statement. “Instead we are focused on helping our member agencies develop local supplies, and looking for other ways we can continue to ensure supply reliability at a reasonable cost.”
