The Chino Desalter Phase 3 Expansion will provide operational flexibility, increase efficiency, and allow the agency to increase the available water supply. The project will help the Chino Basin Watermaster achieve hydraulic control of the Chino Basin to reduce or eliminate migration of brackish groundwater from the southern section of the basin into the Santa Ana River. The project will also address salinity issues that could limit future use of recycled water in the Chino Basin.
