San Antonio Water
The San Antonio Water System (SAWS) provides water for about 1.8 million residents of San Antonio, Texas and Bexar County, as well as parts of Atascosa and Medina Counties. Formed in 1992 through the consolidation of three previous agencies, SAWS collects water primarily from the Edwards Aquifer, but has also recently added other sources such as Medina Lake, Trinity Aquifer, Western Canyon, Carrizon Aquifer, and Lake Dunlap.
