Denton County overview → Permit & regulations → TDLR License #61234 DKMPW Updated August 6, 2026
Lewisville sits in southeastern Denton County, which is geologically bisected east to west. On the eastern side of the county the Woodbine is the primary residential aquifer; across the central and western county the Trinity takes over, with most domestic wells completing in the upper Paluxy sand or the deeper Twin Mountains sand. Lewisville falls near that transition, so the producing aquifer depends on the parcel. Between the Paluxy and the Twin Mountains sits the Glen Rose Formation — mostly solid limestone that holds little water, so a well is cased through it to reach the sand below. Depth varies meaningfully from one parcel to the next, so there’s no single typical figure for the area.
Drilling rates in Denton County typically run $38–$50 per foot. Mixed formations and occasional hard limestone can affect total project cost. Longer term, the district projects the water level in the deeper Twin Mountains sand under Denton County to drop several hundred feet by 2080 — the steepest decline in the region — which is worth designing a well around.
Denton County Permit Requirements
New wells in Denton County are regulated by the North Texas Groundwater Conservation District.
