WRD Robert W. Goldsworthy Desalter


The Robert W. Goldsworthy Desalter located in the City of Torrance Was commissioned in 2001 and expanded in 2018. This facility treats 5 million gallons per day (mgd) of brackish groundwater extracted from the West Coast Groundwater Basin. The plant is owned by WRD and operated by the City of Torrance. The treated water produced by this facility is used as potable water in the City of Torrance.

WRD's Groundwater Desalter works primarily through the use of reverse osmosis treatment. Salty brackish groundwater extracted from wells is forced through reverse osmosis membranes to remove the salts in the water. The water is then disinfected and the pH level is adjusted to create fresh, potable water.
