Grayson County overview → Permit & regulations → TDLR License #61234 DKMPW Updated August 7, 2026

Wells around Tioga draw mainly from the Woodbine, the primary residential aquifer in the central and eastern part of Grayson County where it reaches the surface. Below it sits the Trinity aquifer: because the Glen Rose Limestone is absent across Grayson County, the Trinity here takes the form of the Antlers Formation — the Paluxy and Twin Mountains sands merged into one unit — a deeper alternative where the Woodbine falls short. Tioga sits in southern Grayson County, so most residential wells target the Woodbine first.

Drilling rates in Grayson County ($28–$40/ft) are among the more affordable in the region.

Grayson County Permit Requirements

All new wells in Grayson County require a pre-drilling permit through the Red River Groundwater Conservation District. The RRGCD sets standards for well construction, spacing, and production across the county. For complete detail on the permitting process, see our guide to Grayson County water well regulations.

Frequently Asked Questions

Which groundwater district covers Tioga?

Tioga is in Grayson County, which falls under the Red River Groundwater Conservation District (RRGCD). A permit is required before drilling a new well. DFW Well Service submits the permit application on your behalf as part of the project.

How deep are water wells near Tioga?

There's no single typical depth around Tioga — it varies meaningfully from one property to the next, so we review the driller's logs from neighboring wells before quoting a depth. Tioga sits in southern Grayson County, in the central-to-eastern part of the county where the Woodbine reaches the surface, so wells here usually target the Woodbine first; the deeper Trinity — the Antlers Formation, the Paluxy and Twin Mountains sands merged into one where the Glen Rose is absent — sits below it as a deeper alternative.

What does well drilling cost near Tioga?

Grayson County drilling rates run $28–$40 per foot. Total cost depends on completion depth and the full system (casing, grouting, pump, pressure tank). We provide a free itemized written estimate after reviewing neighboring driller's logs for your parcel.

Can you work on well and pump systems for rural acreage properties?

Yes. We regularly serve rural and acreage properties in the Tioga area, including pump replacements, pressure tank service, and well rehabilitation. If your pump won't run, your pressure is low, or you have air in the lines, call us for a diagnostic visit.

My well has been unused for years — can it be brought back into service?

Potentially yes, depending on its construction condition and current yield. We can inspect and test an idle well, rehabilitate it if warranted, and bring it back into service. In some cases, rehabilitation is more economical than drilling a new well. Call us to discuss your situation.

Is the well water in Tioga salty or brackish?

Usually fresh. The Woodbine around Grayson County is fresh through the band where it reaches the surface (its outcrop), and Texas Water Development Board mapping shows fresh water reaching unusually far downdip — staying fresh to about 1,500 feet before turning slightly to moderately saline. Iron and manganese are the routine treatment items.
