About the water in Schertz

Schertz is served by Schertz-Seguin Local Government Corporation (SSLGC), which draws from Carrizo-Wilcox Aquifer groundwater treated at the Schertz-Seguin Regional Treatment Plant. Local water tests in the range of 12 grains per gallon, based on the most recent utility averages.

Schertz spans the Bexar-Guadalupe county line along the I-35 northeast corridor. Most of the city draws Carrizo-Wilcox groundwater through the SSLGC system, which runs moderately hard at around 12 grains per gallon. That is lower than Edwards Aquifer supply across the river in Bexar County, but still well above the softening threshold. Newer subdivisions on the Guadalupe side often have no water treatment in place and residents notice the difference in dishwasher spots and shower glass within the first month.

Common local water concerns

  • Hard water minerals (calcium, magnesium, approximately 12 grains per gallon)
  • Total dissolved solids (elevated in Carrizo-Wilcox supply)

Why Water Testing fits Schertz

  • Bench test for hardness, chlorine, pH, and total dissolved solids.
  • Report cross-referenced against the utility CCR.
  • Treatment recommendation only if the test shows it is needed.
