Wells around Brock draw dependable water from the Trinity aquifer once they reach the Paluxy sand. Brock sits in the western part of Parker County’s outcrop belt, where the Paluxy — the main water-bearing sand across the county — reaches close to the surface in places, so some wells finish relatively shallow. Elsewhere it lies buried under Cretaceous limestone that slows drilling and pushes the well deeper. Beneath the Paluxy, the Glen Rose Formation is mostly solid limestone that seals the sand below, and deeper still the Twin Mountains sand is the high-yield producer once a well reaches it.
Brock’s rural character means the great majority of properties depend on private wells rather than municipal service. Farm and livestock operations often need higher-yield wells than a typical residential completion, and we can design and drill for those requirements.
Parker County Permit Requirements
Any new water well in the Brock area of Parker County requires authorization from both TDLR and the Upper Trinity Groundwater Conservation District. The Upper Trinity GCD sets well spacing and property-line setback rules and requires a completion report once the well is finished; TDLR construction standards cover casing, grouting, and setbacks from septic systems.
