Hawaii well drilling cost

Cost to Drill a Well in Hawaii

Nationwide, residential well drilling runs about $21 to $42 per foot for the hole and casing, and a complete private water system commonly totals $5,000-$15,000. Local depth data for Hawaii is limited, so this page leans on national rates - use it as a starting point, then get local quotes.

Typical U.S. well drilling rates by depth

These are national average residential rates for the drilling and casing, not Hawaii-specific prices. Rates fall into depth bands, with a setup (mobilization) fee on top. Use them as a yardstick, then get local quotes.

Well depth	Drilling + casing (per ft)	Setup fee
Up to 100 ft	$28 - $42	$400 - $600
101-300 ft	$24 - $36	$400 - $600
301-600 ft	$25 - $30	$750 - $800
601 ft and deeper	$21	$1,000

National residential rate model, drilling and casing only. Higher per-foot rates apply to larger casing and hard-rock drilling. Pump, pressure tank, treatment, and permits are separate (see below).

What Hawaii well records actually show

Cost follows depth, so the most useful Hawaii number we have is the real one: our database holds 5,300 water-well records across Hawaii. Depths on file vary too widely here to state a reliable average, so lean on a local driller's read of nearby records. These are real construction records you can review before you hire.

Beyond the hole: the complete water system

The drilled hole and casing are only part of the bill. A working well also needs a pump and pressure tank, wiring and a pitless adapter, a sanitary cap and grouting, water testing, and often treatment for hardness, iron, or bacteria. Add it up and a complete private well system commonly runs $15,000-$40,000 for Hawaii, based on our state cost research, versus $5,000-$15,000 nationwide. The low end is a shallow well with simple equipment; the high end is a deep well with treatment and difficult access. A typical Hawaii project takes 1-4 months from planning to usable water.

What drives the cost of a well in Hawaii

Depth
The biggest lever. Because drilling is priced largely per foot, a deeper well costs proportionally more. Local records set the expectation.
Geology and casing
Hard rock drills slower and can push per-foot rates toward the high end. Loose or caving formations need more casing, which adds material cost.
Water table and yield
Wells are drilled well past the first water to reach a dependable, year-round aquifer. A low-yield zone can mean drilling deeper.
Pump, tank, and treatment
The pump, pressure tank, and any treatment for hardness, iron, or bacteria are a large share of a complete system - often several thousand dollars.
Permits and testing
Hawaii: CWRM permit required. Permit, inspection, and water-test fees are usually modest but affect the timeline.
Site access
A rig needs room to work. Tight lots, long driveways, steep grade, or remote sites raise mobilization and labor.

Well drilling cost FAQ for Hawaii

Cost tracks depth, geology, and casing. Nationwide, residential drilling runs about $21 to $42 per foot for the hole and casing, and a complete private water system (pump, pressure tank, treatment, permits) commonly totals $5,000-$15,000. We hold limited depth data for Hawaii, so ask two licensed local drillers for written quotes to pin down your number.

Typical U.S. residential rates run about $21 to $42 per foot for drilling and casing, with the lower end on shallow, small-casing wells and the higher end on shallow large-casing or hard-rock work. Most drillers also charge a setup or mobilization fee of a few hundred dollars. These are national averages, not Hawaii-specific prices - your driller's rate depends on local rock and rig.

Permitting in Hawaii: CWRM permit required (HRS Section 174C-84). Permit and inspection fees are usually a small part of the total, but they affect the timeline. A licensed Hawaii contractor typically pulls the permit and folds it into the quote.

The drilled hole and casing are only part of it. A working system also needs a pump and pressure tank, wiring and a pitless adapter, a well cap and grouting, water testing, and often treatment for hardness, iron, or bacteria. Those add several thousand dollars on top of the drilling, which is why a complete private well system commonly runs $5,000-$15,000.
