Seawater Desalination Projects in the 2012 State Water Plan

In the 2012 State Water Plan, three regional water planning groups (H, L, M, and N) recommended seawater desalination as one of the water management strategies that would produce 253,514 acre-feet per year of new water supplies by 2060. The 2012 State Water Plan projects that the strategy would represent 2.8% of all the new supplies in the state.

*The 2012 State Water Plan was amended on January 2015 to add a seawater desalination water management strategy.

**The 2012 State Water Plan was amended on November 2014 to change seawater desalination as a alternative to recommended water management strategy.

Brackish Groundwater Desalination Projects in the 2012 State Water Plan

In the 2012 State Water Plan, six regional water planning groups (E, F, H, L, M, and O) brackish groundwater desalination as one of the water management strategies that would produce 184,704 acre-feet per year of new water supplies by 2060. The 2012 State Water Plan projects that the strategy would represent 2% of all the new supplies in the state.
