How Much Does a Water Well Cost in Texas? (2026 Guide)

1. Drilling — usually billed per foot. In 2026 the Hill Country range is roughly $35–$60 per foot for the borehole itself, depending on formation hardness and casing requirements. A 400-ft well runs $14,000–$24,000 just for the drilling phase.

2. Surface casing and grouting — required by Texas law and the local groundwater conservation district. Typically $2,000–$5,000 depending on county and depth.

3. Pump and motor — a quality submersible (Franklin, Grundfos, Goulds) sized for residential demand runs $1,200–$3,500 for the pump itself, plus wire, splice kit, torque arrestor, safety rope, and pitless adapter.

4. Pressure tank and controls — a properly sized bladder tank, pressure switch, and gauge run $700–$2,500. Constant-pressure VFD controllers add $1,500–$3,000 but pay back in pump life and water comfort for larger homes.

5. Trenching, electrical, and tie-in — the line from well to house, the electrical to the pump, and the connection to your plumbing. $1,500–$5,000 depending on distance and elevation.

Boerne, Comfort, and Kendall County (Trinity aquifer, 350–650 ft): $19,000–$29,000 turnkey.

Marble Falls and Burnet County (mixed Trinity and Ellenburger, 300–650 ft): $18,000–$28,000 turnkey.

Dripping Springs and Hays County (Trinity, 300–900 ft variable): $20,000–$34,000 turnkey, with significant range because of depth uncertainty.

Fredericksburg and Gillespie County (Hickory aquifer, 500–800 ft): $24,000–$38,000 turnkey. Hickory wells are deeper, so drilling cost is higher; mineral treatment is sometimes additional.

Blanco County and ranch wells (Trinity, 350–700 ft): $19,000–$32,000 turnkey, with ag-sized systems running higher.

Total depth — the single biggest variable. Every additional 100 ft adds roughly $4,000–$6,000 to the project.

Casing requirements — some counties require steel casing through the entire fresh-water zone. PVC liner is cheaper but not always allowed.

Pump size and pressure system — a 7 GPM pump for a small home is much cheaper than a 20 GPM constant-pressure system for a 5-bath home with irrigation.

Distance from well to house — long pipe runs add trenching cost and sometimes require a buffer tank.

Granite vs limestone vs sandstone — drilling rates vary by formation hardness, and the Hill Country has all three within a few miles of each other.

Oversized pumps. A 20 GPM pump in a 2-bath house cycles too often, wears out faster, and was unnecessary in the first place. Sizing should match real fixture count, not a sales preference.

Cheap pressure tanks. A $300 import-grade tank fails in 3–5 years and ruins the pump on its way out. A quality bladder tank runs $700–$1,200 and lasts 12+ years.

No yield test. Skipping the bail and drawdown test before paying for the pump is the most expensive shortcut in the industry. You learn the well is weak only after you have spent $25,000.

Forgetting financing. Most homeowners qualify for monthly payments rather than a lump sum, often at competitive rates, and never ask.
