Sweetwater Authority is a publicly-owned water agency with policies and procedures established by a seven-member Board of Directors.
Sweetwater Authority provides safe, reliable water service (since 1977) to approximately 191,500 people in National City, Bonita and the western and central portions of Chula Vista, California.
Sweetwater Authority owns and operates Loveland Reservoir, Sweetwater Reservoir, a brackish groundwater desalination facility and deep freshwater wells. Water obtained in each of these areas is influenced by the 230-square-mile Sweetwater River Watershed, a land stretching from the Cleveland National Forest to San Diego Bay.
