State regulators certified the water supply from the Carlsbad Desal Plant as drought-resilient, reducing the regional impacts of emergency water-use mandates the state imposed in June 2015. The State Water Resources Control Board’s certification lowers the regional aggregate water conservation goal from 20 percent to about 13 percent, though water-use targets will continue to vary by local water agency.

Vallecitos Water District, the only retail water provider with a direct connection to the Carlsbad plant, will have its conservation target dropped to 16 percent compared to its previously mandated 24 percent reduction in potable water use.
