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.
