As California continues to try new ways to deal with the ongoing drought, one city has agreed to advance a $2.5-billion plan to recycle wastewater for drinking.

The 9-0 vote by the San Diego City Council is the latest example of how California cities are taking a closer look at recycled water.

The plan calls for initial production of 15 million gallons a day by 2023 and 83 million gallons a day by 2035, or about one-third of the city's water supply.

San Diego would join Southern California's Orange County Water District as one of the nation's largest producers of recycled water for drinking.

Orange County plans to increase production to 100 million gallons a day next year — from the current 70 million gallons a day.
