How Much Does It Cost to Drill a Water Well in North Texas?
Quick Answer
A complete residential water well in North Texas costs $8,000–$50,000+ depending on depth, formation, and county. Most fall $14,000–$28,000.
Drilling a water well is a one-time infrastructure investment, and cost varies more by county than most homeowners expect. Complete residential systems in North Texas run $8,000–$50,000+ depending on depth, formation, and county. The typical range across the 19 counties we serve is $14,000–$28,000, with shallower wells in Somervell, Grayson, and Fannin counties coming in lower and deep confined Trinity wells in Dallas and Ellis counties pushing higher. Here’s what drives price across our service area.
What Drives Well Drilling Cost
Formation Type and Depth
Formation type is the biggest variable most homeowners don’t know to ask about. Soft sandy formations drill fast; hard limestone formations are slow, hard on equipment, and more expensive per foot.
| County | Typical Depth | Est. Complete Cost | Governing GCD | Permit/Reg Fees |
|---|---|---|---|---|
| Collin | Varies by parcel | $16,000–$36,000 | North Texas GCD | $500 registration |
| Cooke | Varies by parcel | $12,000–$28,000 | North Texas GCD | $500 registration |
| Dallas | Varies by parcel | $40,000+ (residential atypical — deep confined Trinity) | None (TDLR only) | $0 |
| Denton | Varies by parcel | $12,000–$30,000 | North Texas GCD | $500 registration |
| Ellis | Varies by parcel | $17,000–$40,000 (Woodbine; deep Trinity higher) | Prairielands GCD | $500 registration |
| Erath | Varies by parcel | $12,000–$24,000 | Middle Trinity GCD | $200 deposit (refundable) |
| Fannin | Varies by parcel | $9,000–$35,000 | Red River GCD | Application required |
| Grayson | Varies by parcel | $9,000–$24,000 | Red River GCD | Application required |
| Hood | Varies by parcel | $16,000–$42,000 | Upper Trinity GCD | $600 + $100 deposit |
| Hunt | 300–650 ft | $12,000–$28,000 | None (TDLR only) | $0 |
| Johnson | Varies by parcel | $14,000–$40,000 | Prairielands GCD | $500 registration |
| Kaufman | Varies by parcel | $12,000–$35,000 | None (TDLR only) | $0 |
| Navarro | 100–800 ft | $20,000–$38,000 | None (TDLR only) | $0 |
| Palo Pinto | 100–450 ft | $15,000–$45,000 (highly variable; fracture-dependent, dry holes possible) | None (TDLR only) | $0 |
| Parker | 250–550 ft | $16,000–$36,000 | Upper Trinity GCD | $600 + $100 deposit |
| Rockwall | Varies by parcel | $18,000–$45,000 (limited groundwater; supply not assured) | None (TDLR only) | $0 |
| Somervell | Varies by parcel | $8,000–$22,000 | Prairielands GCD | $500 registration |
| Tarrant | Varies by parcel | $18,000–$35,000 | Northern Trinity GCD | $500 + $200 deposit |
| Wise | Varies by parcel | $12,000–$25,000 | Upper Trinity GCD | $600 + $100 deposit |
Costs reflect 2026 regional benchmarks of $45–$60 per foot for complete systems (drilling, casing, pump, pressure tank, and electrical), plus applicable GCD permit fees. Counties marked “None (TDLR only)” still require the driller to file the State of Texas Well Report with TDLR within 60 days of completion, but no local aquifer-management fee applies. Costs at the upper end of each range typically reflect deeper wells, harder formations, or high-capacity household demand.
What’s in a Complete Quote vs. Drilling Only
Some contractors quote drilling only — just the borehole. Others quote a turnkey system. The pump, pressure tank, and wiring add $3,000–$6,000 to the project cost. Always confirm which of these items are included:
- Drilling to target depth
- Steel or PVC casing and grouting
- Well development (flushing and surging to maximize yield)
- Submersible pump sized to your household demand
- Pressure tank (typically 20–86 gallons)
- 240V electrical wiring and pump control box
- Pitless adapter and sanitary wellhead seal
Mobilization Fees
Most North Texas drillers charge a mobilization fee of $500–$2,000 depending on rig travel distance. Properties in Somervell, Palo Pinto, or Erath counties may pay more for rig travel than those near the I-35 and Highway 287 corridors.
What You Get for the Investment
A properly drilled residential well typically:
- Produces 3–10 gallons per minute (GPM) — most households need 1–3 GPM continuous
- Casing lasts 20–50+ years; pump and pressure tank are replaced every 10–20 years
- Eliminates monthly water bills (average North Texas city water: $50–$150/month)
- Adds value for rural buyers who prefer private water supply
Why are wells in Denton, Tarrant, and Grayson counties so deep?
Decades of municipal and industrial pumping along the IH-35 corridor have lowered the Trinity Aquifer water level by 350 to over 1,000 feet in some areas. New wells in those counties often have to drill past the historic water table to reach a productive zone, which drives both depth and cost upward. The Texas Water Development Board tracks aquifer drawdown and the Northern Trinity GCD and North Texas GCD set production limits intended to slow further declines. For homeowners, the practical implication is that a 2026 Tarrant or Denton County well will typically be 100–300 feet deeper than the same property’s well drilled in the 1990s.
