Headquartered in Chula Vista, Calif., Sweetwater Authority is a publicly owned water agency with policies and procedures established by a seven-member board of directors. It has been providing water purification services for more than 25 years to more than 150,000 people in National City, Bonita, and the western and central portions of Chula Vista in California. Sweetwater Authority owns and operates Loveland reservoir, a brackish groundwater desalination facility, and Sweetwater reservoir that has deep freshwater wells. Sweetwater Authority treats its surface water supplies at the Robert A. Perdue treatment plant at Sweetwater reservoir in Spring Valley, Calif. Particles are removed from the water through a four-step cleaning process, it is disinfected with chlorine and ammonia, and chemically bound together to form chloramines. The water is also treated to improve its taste, color and odor.
