Greenville’s municipal supply is surface water — the city draws from Lake Tawakoni through the Sabine River Authority — but the rural wells around it tap the Nacatoch Sand, a unit of the Navarro Group. It is not the Trinity or the Woodbine that show up on generic North Texas well descriptions: the Trinity runs far too deep to drill for a home (regional projections exceed 3,000 feet), and the Woodbine only yields good water up around Celeste in the northwest of the county. The Nacatoch outcrops in a belt running from north of Commerce southwest through Cash and dips toward the southeast.

Greenville sits on the downdip side of that belt, so the sand sits toward the deeper end of its 300-to-650-foot range and is more likely to carry higher dissolved solids than the fresher updip wells. Nacatoch water is soft and sodium-rich rather than the hard, calcium-heavy water common in Trinity wells to the west.

Hunt County Permit Requirements

Hunt County has no active groundwater conservation district, so well construction follows TDLR statewide standards rather than a local district permit. You do not need a GCD permit before drilling. However, your driller must hold a current TDLR license, the well must meet the Texas Well Construction Standards, and a Well Report must be filed with TDLR after completion. For the full picture, see our guide to Hunt County water well regulations.

One honest wrinkle worth knowing: because there is no district and the Nacatoch recharges very slowly — and faulting can sharply separate one part of the aquifer from another — a neighbor’s heavy pumping can have a real and lasting effect on your well, with no local avenue to address it. We will factor that into how we site and size your well.

DFW Well Service is fully licensed and handles all required TDLR reporting on your behalf. Call (940) 536-8560 for a free estimate on any new well or service project in Greenville or Hunt County.

Frequently Asked Questions

Is Greenville on city water or private wells?
Inside Greenville, most homes are on the municipal system, which is supplied by surface water — the city draws from Lake Tawakoni through the Sabine River Authority. Private wells are most common on the rural, unincorporated acreage outside the city and its water lines. If you are on the edge of town or on acreage, confirm whether a public line reaches your parcel before you plan a well.
What aquifer do wells near Greenville tap into?
The Nacatoch Sand, a unit of the Navarro Group, is the principal local aquifer across Hunt County — an older TWDB report identified it as the only formation yielding water low enough in dissolved solids for domestic supply in the Greenville area. The Trinity is far too deep to drill for a home (regional projections exceed 3,000 feet), and the Woodbine only yields good water up around Celeste in the northwest of the county.
How deep are water wells in the Greenville area?
Nacatoch wells in Hunt County generally run about 300 to 650 feet. Greenville sits toward the downdip side of the outcrop belt, so wells here tend toward the deeper end of that range. Exact depth depends on your parcel and is best estimated from nearby TDLR driller's logs.
Is the well water around Greenville hard or salty?
Nacatoch water is usually soft and sodium-bicarbonate in character — not the hard, calcium-heavy water common in Trinity wells west of here. The trade-offs are that total dissolved solids commonly run 500 to 1,500 mg/L downdip, with a brackish belt in parts of the county, iron is often moderate to high, and the high sodium makes it poor for landscape irrigation. A full water test before you set any treatment plan is money well spent.
Do I need a permit to drill a well in Hunt County?
Hunt County has no groundwater conservation district, so there is no local GCD permit. Your driller still must be TDLR-licensed, the well must meet the Texas Well Construction Standards, and a completion report must be filed with TDLR after the work is done. We handle that reporting for you.
How long does a well last around Greenville?
A properly constructed and maintained well can serve a household for decades, though the pump and pressure tank are wear items that get replaced along the way. Because the Nacatoch recharges slowly, it is worth sizing the well and pump conservatively; we can advise based on records near your property.
Can DFW Well Service test my water and service my pump in Greenville?
Yes. Greenville and all of Hunt County are in our service area for new wells, pump repair and replacement, water testing, and well rehabilitation. Call (940) 536-8560 and we will get a technician scheduled.
