What this calculator estimates
Estimate a private-water-well project cost from drilling depth, casing, pump, testing, permits, access and contingency.
How to use it
Enter Estimated well depth (ft); Drilling cost per foot ($); Casing cost per foot ($); Pump, pressure tank and controls ($); Water testing and treatment setup ($); Permits and professional services ($); Mobilization and site access ($); Contingency (%). Select Calculate to update the results.
How the calculation works
The estimate multiplies depth by drilling and casing rates, adds pump, testing, permits and access, then applies contingency.
Worked example: starting scenario
| Estimated well depth (ft) | 300 |
|---|---|
| Drilling cost per foot ($) | 40 |
| Casing cost per foot ($) | 15 |
| Pump, pressure tank and controls ($) | 2500 |
| Water testing and treatment setup ($) | 400 |
| Permits and professional services ($) | 600 |
| Mobilization and site access ($) | 1000 |
| Contingency (%) | 10 |
| Estimated well-drilling project cost | $23,100.00 |
|---|---|
| Drilling and casing | $16,500.00 |
| Pump and water system | $2,500.00 |
| Testing, permits and access | $2,000.00 |
| Estimated cost per foot | $77.00 |
Important limitations
Geology, required depth, diameter, casing, yield, access, abandoned attempts, treatment needs and local permits can cause wide cost differences.
