Private-water cost tool

Water Well Drilling Cost Calculator

Estimate a complete private-well project from depth, drilling rate, casing, pump, tank, testing, permits, mobilization and uncertainty—not drilling footage alone.

Depth-based estimate

Complete private-well project

How the result works

The assumptions stay visible.

Depth × rateDrilling and casing are calculated from the entered feet and per-foot assumptions.
Complete systemPump, pressure tank, controls, electrical, testing, permits, mobilization and treatment should be budgeted separately.
Uncertainty rangeThe high range preserves a contingency for hard drilling, extra casing, low yield, deeper completion or other unknown conditions.

Worked examples

See how the inputs change the decision.

Example

150-foot planning case

Inputs: 150 feet, local drilling and casing assumptions, standard pump/tank allowance, testing, permits and 15% contingency

Illustrative result: A complete-system estimate substantially above footage-only drilling cost

Use nearby official well records to choose a plausible depth range, then ask contractors what is included in the per-foot quote.

Example

300-foot deeper-well case

Inputs: 300 feet with more casing, larger electrical allowance and treatment placeholder

Illustrative result: Higher drilling, casing, pump and uncertainty exposure

Depth can affect pump sizing and power requirements as well as drilling cost.

Example

500-foot stress test

Inputs: 500 feet, difficult-condition rates and a larger contingency

Illustrative result: A high-cost scenario for evaluating whether the land still fits the total project budget

A stress test is not a prediction; it shows whether the purchase remains viable if the optimistic depth is wrong.

Questions

Before you rely on the estimate

Is this an oil or gas well drilling cost calculator?

No. This tool is only for private water-well planning for land and homes. Oil, gas and geothermal drilling use different engineering, regulation, equipment and cost models.

How can I estimate well depth?

Review official well records, nearby drillers and hydrogeologic context, while recognizing that nearby results may not match the parcel.

Is drilling cost the same as complete well cost?

No. A complete system can include casing, pump, tank, controls, electrical work, testing, permits, mobilization, treatment and site restoration.

What if the well has poor yield or quality?

The project may require storage, treatment, deeper drilling, another source or a different site plan. These outcomes can materially change feasibility and cost.

What should I ask a well contractor?

Ask what footage and materials are included, how casing and difficult conditions are charged, what happens if yield is poor, which pump and electrical items are excluded, and how abandonment or redrilling is handled.

Do well records prove water is available?

No. Records show prior reported conditions at specific locations and dates. They do not guarantee current or parcel-specific depth, yield, quality or permitting.

Next step

Cost matters only after water availability, legal use, records, yield, quality and system design are investigated.
