Cooke County overview → Permit & regulations → TDLR License #61234 DKMPW Updated June 4, 2026

Wells around Gainesville draw from two layers: the Woodbine sand nearer the surface and the deeper Antlers sand of the Trinity. Gainesville sits mostly on the Woodbine outcrop, where that sand reaches the surface. Beneath the county the Glen Rose limestone is absent, so the Trinity’s Paluxy and Twin Mountains sands merge into the single unit called the Antlers, which underlies the Woodbine at depth. A home well here completes in the Woodbine where it’s present and productive, or in the Antlers beneath it. (The area’s older Trinity public-supply wells have shown significant long-term water-level decline since the 1930s.)

Drilling costs in Cooke County run on the more affordable end of our service area thanks to manageable shallow-Woodbine drilling in many places.

Cooke County Permit Requirements

New wells in Cooke County require a pre-drilling permit through the North Texas Groundwater Conservation District. As a local driller, we work with the NTGCD regularly and are familiar with their process and requirements. For more on Cooke County permitting, see our guide to Cooke County water well regulations.

Frequently Asked Questions

Is DFW Well Service based in Gainesville?
Yes. Gainesville is our home base. DFW Well Service is a locally owned well drilling and pump service company headquartered in Gainesville, TX. We serve Cooke County and the surrounding region, and our team lives and works here. When you call us for service in Gainesville, you get the fastest response time in our service area.
Which groundwater district covers Gainesville?
Gainesville and Cooke County fall under the North Texas Groundwater Conservation District (NTGCD). A pre-drilling permit is required for new wells. Because we're local and work with the NTGCD regularly, we know the process well and can move efficiently through permitting.
How deep are water wells in Gainesville?
There's no single typical depth around Gainesville — it varies meaningfully by parcel, so we review the driller's logs from neighboring wells before quoting a project. Gainesville sits mostly on the Woodbine outcrop (where that sand layer reaches the surface), and beneath the county the Glen Rose limestone is absent, so the Trinity's Paluxy and Twin Mountains sands merge into one layer called the Antlers. One caution: the old municipal and industrial Trinity wells around Gainesville ran 840–1,025 feet deep, but those are public-supply wells — a home well shouldn't be planned around those depths.
What does well drilling cost in Gainesville?
Cooke County drilling rates run on the more affordable end of our service area thanks to relatively manageable shallow-Woodbine drilling in many places. Final cost depends on completion depth, casing, pump, and pressure equipment. Call us for a precise estimate after we review neighboring driller's logs for your parcel.
How quickly can you respond to a pump emergency in Gainesville?
Being locally based means we can often respond to pump emergencies in Gainesville same-day or next-day. If you wake up with no water, call us first thing and we'll do everything we can to get you back in service quickly.
Do you drill irrigation and livestock wells in Cooke County?
Yes. In addition to domestic wells, we're equipped to drill irrigation and livestock wells for agricultural properties throughout Cooke County. Larger-capacity wells for irrigation and stock tanks require non-exempt permits through the NTGCD, and we manage that process for you.
Is the well water in Gainesville salty or brackish?
Usually not in the zones home wells use. The Woodbine around Gainesville is fresh through its outcrop band (where the sand reaches the surface) down to about 1,500 feet, and the Antlers Trinity sand is fresh where it surfaces to the west. Water turns saltier with depth and toward the southeast, per Texas Water Development Board mapping, so it's worth testing total dissolved solids (a measure of how mineral-heavy the water is) on deeper wells.
