Wells around Decatur draw from the Trinity aquifer, and central Wise County is geologically distinctive in how those layers stack. This is where the Glen Rose Limestone — the thick limestone layer found across most of the region’s Trinity outcrop — thins out to nothing. With the Glen Rose gone, the Paluxy and Twin Mountains sands merge into one body known as the Antlers Formation, the main producing zone for Decatur-area wells. In practice that often means cleaner, sandier drilling here than through the layered Glen Rose stack still found in Hood County and southern Wise to the south.
Decatur’s status as Wise County seat means the city itself is served by municipal water, but the surrounding rural county — with its mix of ranches, hobby farms, and rural homesteads — is heavily dependent on private wells. We’re available to serve customers throughout the Decatur area.
Wise County Permit Requirements
Water wells in Wise County fall under the jurisdiction of both TDLR and the Upper Trinity Groundwater Conservation District. The GCD requires a permit before drilling begins and a completion report once the well is finished. Setback requirements from property lines, buildings, and septic systems must also be observed.
