Why San Antonio Homes Need Water Treatment
Local water quality, hardness levels, and supply sources make water treatment a smart investment for San Antonio–New Braunfels-area homeowners.
San Antonio's water comes from the Edwards Aquifer, a massive limestone formation where water has filtered through calcium-rich rock for thousands of years. This gives the city some of the hardest municipal water in America — SAWS reports typical hardness of 15 to 20 grains per gallon, nearly double the "very hard" threshold. Homes throughout Bexar County, from Alamo Heights to the rapidly growing far northwest side, deal with aggressive scale buildup that shortens appliance life and clogs plumbing.
