About the water in Universal City

Universal City is served by San Antonio Water System (SAWS), which draws from Edwards Aquifer and supplemental Carrizo-Wilcox Aquifer supply via SAWS regional system. Local water tests in the range of 15 grains per gallon, based on the most recent utility averages.

Universal City borders Randolph Air Force Base on the northeast side of the San Antonio metro and draws SAWS water from the same Edwards Aquifer source as the rest of Bexar County. Military families rotating through the base area frequently compare their water quality experience to previous duty stations. San Antonio's hard water at 15 to 20 grains per gallon stands out against softer supply regions. Water softeners are among the most requested service calls in the Universal City and Randolph area.

Common local water concerns

  • Hard water minerals (calcium, magnesium, 15 to 20 grains per gallon typical)
  • Trihalomethanes (within EPA MCL per SAWS 2024 CCR)
  • Chloramines

  • Report cross-referenced against the utility CCR.
  • Treatment recommendation only if the test shows it is needed.
