Overview

The existing Arlington Desalter facility, operating since 1990, extracts and treats impaired groundwater from the Arlington basin in the southwestern area of the City of Riverside.  The Desalter, using Reverse Osmosis (RO) technology, produces up to six (6) million gallons per day (MGD) of blended desalinized water, with another estimated one (1) MGD of concentrated brine (high salinity water) generated by the plant discharged to the Santa Ana Regional Interceptor (SARI) line. The Desalter was managed and operated by SAWPA until 2005. At that time, the Desalter assets and operations were transferred to SAWPA’s member agency, the Western Municipal Water District.
