About Our Facilities

The CDA produces 24,600 acre-feet per year of high-quality water that is delivered to the municipal water supply systems for the Member Agencies: Cities of Chino, Chino Hills, Norco and Ontario; Jurupa Community Services District; and Santa Ana River Water Company. The CDA facilities include two desalters, supply wells for each desalter, two reservoirs, raw water pipelines, potable water pipelines, potable water pumping facilities, and pipelines for brine disposal.

The treatment processes at the Chino I and Chino II Desalters include Reverse Osmosis (RO) and Ion-Exchange (IX) for removal of nitrate and total dissolved solids (TDS). The Chino I Desalter also includes air stripping for removal of some volatile organic chemicals (VOC).


Chino I Desalter


The Chino I Desalter is located in Chino and began operation in 2000. Chino I produced an average of 11.1 million gallons per day of drinking water in 2012. Chino I produces approximately 2 million gallons per day of brine, a byproduct of the reverse osmosis and ion exchange processes, which is transported by the Inland Empire Brine Line (IEBL) to Orange County and is subsequently discharged to the ocean.


Chino II Desalter


The Chino II Desalter is located in Jurupa Valley and began operation in 2006. Chino II produced an average of 10.6 million gallons per day of drinking water in 2012. Chino II produces a little more than 1 million gallons per day of brine that is transported by the Inland Empire Brine Line (IEBL) to Orange County and is subsequently discharged to the ocean.
