The national average
For a complete, usable residential water well, most homeowners pay between $3,750 and $15,300, with a typical project around $5,500.
"Cost to drill a well" is really two numbers. The borehole - the drilled, cased hole in the ground - runs about $15 to $30 per foot. A complete system you can actually draw water from adds a pump, a pressure tank, wiring, a well cap, and a water test on top of that. The figures on this page are national averages; geology, depth, and access in your area can move them substantially, so always get local quotes.

Cost per foot
Drillers usually price by the foot. What is included in that per-foot rate is the thing to pin down.
National averages. Hard-rock regions and remote sites run at the high end; get local quotes.
Cost by depth
Depth is the single biggest driver: more feet to drill, and a stronger pump set deeper in the hole.
Complete systems (borehole + casing + pump + tank + wiring). Your local water-table depth determines how deep you must go - check your state's well-log records.
Not sure how deep the water sits under your lot? You can check the typical water table depth near you from recorded wells - a useful gut-check before you budget by depth.
The hole vs. a complete system
The most common pricing surprise: a quote that covers only the borehole.
A drilled, cased hole is not yet a working water supply. To get water to the house you also need a pump and pressure tank, electrical wiring to the pump, a sanitary well cap, and - before you drink it - a water test. When you compare quotes, confirm whether each one is hole-only or a complete, water-to-the-house system, or you will be comparing very different numbers.
Itemized components
What the major line items typically cost in a complete well project.
A new well should be tested before anyone drinks from it.
Already have a well and just need the pump done? See our well pump replacement cost guide. Ready to confirm your new well is safe? Order a certified well water test.
Drilled vs. dug vs. driven
Three ways to put in a well, at very different price points and reliability.
What drives cost up
- Depth. Every additional 100 feet adds drilling footage and usually a larger, deeper-set pump.
- Geology. Drilling through bedrock costs far more per foot than soil or sand - hard rock can double the per-foot rate.
- Site access. A drill rig needs room to set up; a tight, sloped, or remote lot raises mobilization costs.
- Casing material and diameter. Steel costs more than PVC; larger-diameter wells cost more per foot.
- Water-table depth. The deeper the reliable aquifer, the more you drill and the more pump you need.
- Permits and local rules. County permit fees and required setbacks, grouting, or testing vary widely by state.
Financing & assistance
A new well is a big one-time cost; a few programs can help spread or offset it.
- USDA Rural Development (Section 504) offers repair loans and, for eligible low-income elderly homeowners, grants that can cover water-supply work in rural areas.
- State and county programs. Some health departments and conservation districts offer cost-share or low-interest loans for private well construction or replacement.
- Home-improvement financing. Many drilling contractors partner with lenders, or you can use a home-equity line for a well that adds value and is required for the property to be habitable.
