About the water in Guadalupe County

Guadalupe County is served by Green Valley Special Utility District (GVSUD), Springs Hill Water Supply Corporation, Crystal Clear SUD, and the City of Seguin, which draws from Carrizo-Wilcox Aquifer treated water (purchased from Schertz-Seguin Local Government Corporation) plus Edwards Aquifer wells in the western portion of the county. Local water tests in the range of 15 grains per gallon, based on the most recent utility averages.

Guadalupe County is patchwork-served. Springs Hill WSC covers most of the rural footprint, Crystal Clear SUD covers the I-10 corridor, and Seguin runs its own utility. Hardness reads differently on each side of the county line.

Why Water Softeners fits Guadalupe County

Guadalupe County runs hard at about 15 grains per gallon. That is enough to spot dishes, scale shower glass, and slowly cake the inside of a water heater. A properly sized softener with demand-initiated regeneration is the standard Guadalupe County install.

  • Right-sized resin tank based on household demand.
  • Demand-initiated regeneration, not timer-based.
  • Bypass plumbed for outdoor hose bibs.
