Cost to drill a well in Hawaii: $6,800–$42,500

A drilled, finished water well in Hawaii typically costs $6,800–$42,500, with a midpoint of $22,300. Depth sets most of that price. Hawaii does not publish its well completion reports as a bulk download, so this estimate uses the national depth model of 100 ft to 300 ft, priced at national driller rates.1,2,3,4,5,6,7,8,9

Hawaii has no bulk well-record download we could use, so this page shows statewide estimates from the national depth model and no county figures.

Typical total: $6,800–$42,500, midpoint $22,300.1,2,3,4,5,6,7,8,9

No usable well records for this area, so depths use the national model (100 ft to 300 ft).

Low uses the 25th percentile depth at low rates; high uses the 75th percentile at high rates.

Casing depth of 130 ft is a model assumption; the records for this area do not report casing.2

Where the money goes on a Hawaii well

Drilling is billed by the foot at $25–$75/ft, so the hole alone runs $2,500–$22,500 at the depths above. Casing, the steel or PVC pipe that lines the upper borehole, adds $1,000–$5,900 at $10–$45/ft. Rig setup is a flat $600–$2,500.

The pump, pressure tank, and trench to the house add $2,500–$10,800 on top of the hole. A quote that looks low next to the range above often leaves those three out, so ask for it itemized.

Permits and driller licensing in Hawaii

Water wells in Hawaii fall under Hawaii Commission on Water Resource Management (Department of Land and Natural Resources). No well construction or pump installation may begin without a permit from the Commission on Water Resource Management. The well driller applies for the well permit and the pump installer files a separate pump permit application. Each well permit directs the driller to file a well completion report with the Commission under HRS 174C-85.

Groundwater and well construction in Hawaii

Well cap Submersible pump Casing to about 130 ft Total depth about 200 ft Soil and loose rock Open hole in rock
Cross-section of a 200 ft well with casing to 130 ft, the Hawaii median

Hawaii's islands are the exposed part of the Hawaiian Ridge, a volcanic mountain range, and USGS lists volcanic-rock aquifers as the principal bedrock aquifers there.

A well at the Hawaii median reaches 200 ft with casing to about 130 ft, a model assumption because the records here do not report casing.

Common questions

How much does it cost per foot to drill a well in Hawaii?

Drilling alone runs $25–$75/ft on the rates we compiled. Spread across a whole finished well, including casing, pump, tank, and hookup, the midpoint estimate works out to about $112/ft at a depth of 200 ft. Per-foot quotes rarely include the pump.

Do you need a permit to drill a well in Hawaii?

No well construction or pump installation may begin without a permit from the Commission on Water Resource Management. The well driller applies for the well permit and the pump installer files a separate pump permit application. The driller usually files the paperwork, but the permit is tied to your property, so ask for a copy.

How much do a well pump and pressure tank add in Hawaii?

An installed submersible pump with wire and drop pipe runs $1,000–$4,000, and a pressure tank with its switch runs $500–$1,800. Together they are often the line items missing from a drilling quote, so a quote for the hole alone will look $3,700 cheaper than a finished well.
