If you’re shopping for a water well in Texas, here’s the number you need to know: most residential wells run $15,000–$40,000 or more. That’s a wide range, and it comes down to one thing above everything else: how deep your driller has to go.
This guide breaks down exactly what drives that cost — especially in North Texas, where Trinity Aquifer depths vary dramatically from one county to the next.
The Biggest Cost Driver: Depth
In the well drilling business, depth is everything. Most drillers in Texas price by the foot — typically $65–$120 per foot drilled, depending on geology, casing size, and equipment. That means a 250-foot well could run $16,000–$30,000 just for drilling and casing, before the pump and pressure system go in.
In North Texas, depth varies widely depending on where you are:
- Collin County: 200–400 ft — expect $18,000–$45,000+
- Denton County: 150–440 ft — expect $15,000–$50,000+ in western areas
- Parker/Palo Pinto counties: 300–500+ ft — budget $28,000–$60,000+
- Wise County: 150–300 ft common — typically $15,000–$35,000
- Tarrant County (rural fringe): 200–400 ft — $18,000–$45,000+
Shallower doesn’t always mean better — water quality and yield matter just as much as depth. A good driller knows the local geology and targets productive zones, not just the first water they hit.
What’s Included in a Typical Quote
A complete residential well installation typically covers:
- Drilling — the per-foot cost to bore the hole
- Steel casing — protects the wellbore and keeps surface water out
- Well development — clearing debris so the aquifer flows freely
- Submersible pump — quality residential pumps run $800–$2,500 depending on horsepower and brand
- Pressure tank — $400–$1,200 installed
- Wellhead completion — sealing, surface casing, sanitary cap
What’s usually extra and often underquoted: electrical hookup and conduit ($1,500–$4,000+), water treatment or softening system ($2,000–$8,000+), pressure booster pumps, water testing ($200–$600), and permits ($200–$800 depending on county). Always request a fully itemized quote and ask specifically what is NOT included.
Cost by Well Type
| Well Type | Typical Cost Range | Notes |
|---|---|---|
| Residential domestic | $15,000–$40,000+ | 5–10 GPM typical; depth is the main variable |
| Irrigation/Agricultural | $25,000–$70,000+ | Larger bore, higher flow rate (20–100+ GPM), bigger pump |
| Livestock | $12,000–$30,000+ | Can be shallower depending on herd size and demand |
| Commercial/Industrial | $50,000–$150,000+ | Depends heavily on required flow rate and depth |
Other Factors That Drive Cost Up
- Hard rock geology — drilling through limestone or Palo Pinto formation takes longer and wears equipment faster; drillers charge more per foot
- Site access — remote or heavily wooded lots require clearing, longer hose runs, or specialized equipment
- Casing size — larger diameter casing (6″ vs 4″) costs more but supports higher flow rates
- Pump depth — the deeper the pump sits, the more wire and drop pipe required
- Water quality issues — high iron, sulfur, or hardness means a treatment system on top of everything else
- Mobilization — if you’re far from the driller’s base, expect a trip charge
North Texas Specifically: The Trinity Aquifer
Most of North Texas relies on the Trinity Aquifer — a series of limestone and sandstone formations holding water across a broad swath of north-central Texas. Productive zones sit at very different depths depending on local geology, and depth swings of 100+ feet between neighboring properties are not uncommon.
In the DFW area, you’re generally looking at 150–450+ feet to reach reliable water — meaning a “simple” residential well can legitimately range from $15,000 to $55,000+ depending on where exactly your land sits. A driller working your area regularly will have well logs from nearby properties. That data tells them what depth to target and what yield to expect before they drill a single foot.
Frequently Asked Questions
Can I drill my own well in Texas?
No. Texas requires all water wells to be drilled by a licensed water well driller registered with the Texas Department of Licensing and Regulation (TDLR). Drilling your own well is illegal and can result in fines. TurnKey Wells is fully licensed and insured in Texas.
How long does drilling take?
Most residential wells are completed in 1–3 days of drilling. Add 1–2 days for pump installation and electrical hookup. Weather, hard rock, or unexpected geology can extend the timeline. Commercial and irrigation wells can take a week or more.
Do I need a permit to drill a well in Texas?
Yes, in most cases. Permit requirements vary by county and groundwater conservation district. Your driller should handle the permit application — if they don’t mention it, ask. TurnKey Wells pulls all required permits before drilling begins.
