Two things are true about the cost of water in San Diego: the cost of bringing water here and maintaining the system that does it is rising, but the amount of water San Diegans consume is dropping.

In 1990, the average San Diegan used 235 gallons of drinkable water per day, according to the Water Authority’s records. By 2021, San Diegans cut that almost in half to 130 gallons per day. Megadroughts that triggered mandatory water cutbacks triggered better water conservation habits, which stuck.

But while San Diegans are using less, the costs they pay continue to rise. The cost of San Digeo’s water supply is expected to rise anywhere from 5.5 to 10 percent beginning in 2023, with hefty hikes continuing in the years thereafter.

“Long after I’m dust, these supplies will be valuable to this region,” said Gary Arant, who leads the Valley Center Municipal Water District, of the haul of water rights San Diego has locked up. “Right now, we’ve got a lot of water. It’s expensive, but I think the decisions we made were good.”
