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.
