Desalination in the 2017 State Water Plan

 

Seawater Desalination

In the 2017 State Water Plan, four regional water planning groups (H, L, M, and N) recommended seawater desalination as water management strategy. If implemented, these strategies would produce 116,000 acre-feet per year of new water supplies by decade 2070. This constitutes about 1.4 % of all the recommended water managment strategies.

*The strategy is currently not assigned to serve a specific water user group (in other words, the strategy is recommended but are not planned to provide water to users during the 50-year planning period).

 

Brackish Groundwater Desalination

In the 2017 State Water Plan, eight regional water planning groups (regions E, F, H, J, L, M, N, and O) included groundwater desalination as a recommended water management strategy. If implemented, groundwater desalination strategies will produce about 111,000 acre-feet per year of additional water supply by decade 2070. This constitutes about 1.3 percent of all recommended water management strategies in the state water plan.

Surface Water Desalination

In the 2017 State Water Plan, two regional water planning groups (regions F and P) included groundwater desalination as a recommended water management strategy. If implemented, groundwater desalination strategies will produce about 3,000 acre-feet per year of additional water supply by decade 2070.
