Water Well Drilling Cost Calculator
Estimate the cost of a water well from depth, casing and pump, and see how many gallons the well itself stores — useful for low-yield wells.

| Storage per foot of well | 1.47 gal/ft |
| Water column | 170 ft |
Cost estimate U.S. average prices
| Drilling 250 ft × $45.00 | $11,250 |
| Steel casing 60 ft × $30.00 | $1,800 |
| Permit & water test 1 job × $600.00 | $600.00 |
| Pump, pressure tank & wiring 1 system × $3,500 | $3,500 |
| Estimated total | $17,150 |
- Stored water helps a low-yield well cover peak demand.
- Ask for the well log and a yield (gpm) test when drilling is done.

|---|---|---|
| Well drilling per ft | starting estimate Starting estimate per foot for a 6 in residential well. Rock and depth change it a lot. | |
| Steel casing, installed per ft | starting estimate Starting estimate per foot (6 in). | |
| Well permit & water test per job | starting estimate Starting estimate; set by your state or county. | |
| Pump, pressure tank & wiring per system | starting estimate Starting estimate for a submersible pump system. |
How to use this calculator
- Enter expected depth — neighbors' well logs are the best guide.
- Enter casing depth and diameter.
- Enter the static water level for storage.
- Replace the starting prices with your driller's quote.
Formulas
Gallons per foot = π × (diameter ÷ 2)² × 7.48 (6 in well ≈ 1.47 gal/ft)Stored water = (well depth − static water level) × gallons per footCost = depth × drilling rate + casing feet × casing rate + pump + permit
Questions
How much water is in a 6 inch well?
About 1.47 gallons per foot of water column. 200 ft of water holds about 294 gallons.
How deep will my well be?
It depends on local geology. Your state's well-log database and nearby drillers are the best source.
Why are these prices marked estimate?
There is no national public price series for residential well drilling. Defaults are starting points — replace them with local quotes.
Sources & assumptions
Prices checked 2026-11-10. State pricing multiplies national figures by the U.S. Bureau of Economic Analysis regional price parities (goods for materials, services for labor and services). RPPs compare general consumer price levels (U.S. = 100). They are not construction-specific; we use RPP Goods for materials and RPP Services: Other (excludes rents) for labor and services.
Starting estimates No public price series was found for: Well drilling; Steel casing, installed; Well permit & water test; Pump, pressure tank & wiring. These defaults are editable placeholders — replace them with a local quote.
