Sweetwater Authority customers are among the first in the region to benefit from a desalination process designed to treat "brackish," or saline, groundwater to make it safe for human use.
About the Facility
The Richard A. Reynolds Groundwater Desalination Facility, formerly known as a Demineralization Facility, uses reverse-osmosis treatment (R/O) to remove dissolved salts and microscopic particles, such as bacteria and other contaminants which could be found in alluvial groundwater. The R/O process water is treated to prevent corrosion, and chlorine and ammonia are added to further assure disinfection.
The facility, completed in 1999, can produce 4 million gallons of drinking water per day. It was honored with a 1999 San Diego Orchid in the competition's environmental solutions category.
