Services We Provide in Stephenville
DFW Well Service (TDLR License #61234 DKMPW) is a licensed well contractor serving Stephenville and Erath County with residential, ranch, and agricultural water well services.
Wells here reach the Trinity aquifer’s sand layers — the Paluxy nearer the surface and the deeper Twin Mountains basal sand — with depth varying by parcel; the strongest local anchor is a 332-foot monitor well just south of town on US Highway 281, which has shown only about 11 feet of water-level decline since 2000. Stephenville is itself the headquarters of the Middle Trinity Groundwater Conservation District, the authority that permits every new well here, and we handle that permitting as part of the job.

Wells around Stephenville draw from the Trinity aquifer, and the city is also the headquarters of the Middle Trinity Groundwater Conservation District. The Trinity’s main sand layers here are the Paluxy nearer the surface and the deeper Twin Mountains basal sand; local and district planning materials also break the Trinity into several other named units (Glen Rose, Travis Peak, Hensell, Pearsall, Hosston, and — where the Glen Rose thins south of town — the Antlers), but for a homeowner it’s all one Trinity system. The strongest local depth anchor is the TWDB/MTGCD monitor well south of Stephenville on US Highway 281 (well #3155504): 332 feet deep, completed in the Twin Mountains sand, and tracked continuously since February 2000, with only about 11 feet of water-level decline over 26 years.
Erath County’s agricultural economy — particularly its dairy operations — creates demand for high-yield wells capable of sustaining large water draws. Standard residential wells are also common in the county, and Stephenville’s growing population includes both city residents and rural homeowners on private well systems.
