According to SAWS, "Feasibility studies confirm that there is sufficient quantity and quality of brackish groundwater available in the Wilcox Aquifer to support the SAWS desalination program. Brackish water, which contains dissolved solids, will be treated to drinking standards using a reverse osmosis treatment facility."
