About the water in Bexar County

Bexar County is served by San Antonio Water System (SAWS), which draws from Edwards Aquifer, Carrizo Aquifer, and Trinity Aquifer wells, plus the Vista Ridge regional pipeline. Local water tests in the range of 15 grains per gallon, based on the most recent utility averages.

San Antonio sits over the Edwards Aquifer, one of the most prolific limestone aquifers in the country. That limestone is exactly what makes Bexar County water some of the hardest in Texas, and exactly what makes a softener the most-asked-for install in the metro.

Common local water concerns

  • Hard water minerals (calcium, magnesium)
  • Trihalomethanes (TTHM: 86.2 ppb highest sample vs 80 ppb MCL; running annual average compliant)
  • Chloramines

Why Whole-Home Filtration fits Bexar County

San Antonio Water System (SAWS) disinfects with chloramine, a longer-lasting alternative to free chlorine that does not flash off in a glass of water the way chlorine does. The standard fix in Bexar County is a catalytic-carbon whole-home stack on the main line, which strips chloramine before water reaches a shower head or a kitchen tap. We size the stack to peak household flow so pressure does not drop at the second-floor bath.

  • Catalytic carbon block sized to peak household flow.
  • Pre-sediment cartridge protects the carbon stage.
  • Bypass for landscape and irrigation lines.
