The well driller board in Hawaii and how you get licensed

Last updated 2026-08-19

Do you need a license to be a well driller in Hawaii?

Yes. Contract to drill wells or install well pumps in Hawaii and you need a C-57 well drilling contractor license from the DCCA Contractors License Board. You also need a well construction or pump installation permit from the Commission on Water Resource Management before that hole gets started.^[1][2]

Those are different papers. The license follows the contractor. The permit follows the well.

Hawaii law is blunt on the contractor side. HRS 444-9 says, "No person within the purview of this chapter shall act, or assume to act, or advertise, as general engineering contractor, general building contractor, or specialty contractor without a license previously obtained under and in compliance with this chapter and the rules of the contractors license board."^[1]

C-57 is the specialty class that covers well drilling. There is no pass because the well is agricultural or for one house. Offer the work for pay and chapter 444 applies.

The resource side is just as plain. HRS 174C-82 says, "No well construction or pump installation shall be commenced unless a permit has first been obtained from the commission."^[2]

Homeowners who self-perform still face the CWRM permit. The C-57 card is the piece that applies to the person in the contracting business. Hiring a well driller in Hawaii? Ask for the C-57 number and check it on the DCCA license search before you send a deposit.

Working without the license is not a small paperwork miss. The Contractors License Board can pursue unlicensed activity. CWRM can stop a hole that started without a permit. Deal with both desks first.

Who is the well driller board in Hawaii?

Nobody. Hawaii does not run a standalone well driller board with its own seal. People still search that phrase because that is how most states label the shop. Here the work is split between two agencies.

The Contractors License Board inside DCCA Professional and Vocational Licensing issues and disciplines the C-57 well drilling contractor license. That board also handles the other contractor classes under HRS chapter 444.^[6]

The Commission on Water Resource Management sits in the Department of Land and Natural Resources. CWRM writes well construction rules, issues well construction and pump installation permits, and collects well completion reports.^[3][4]

Call one office expecting the other office's form and you lose a week. DCCA will not permit your well. CWRM will not hand you a C-57.

Paper	Agency	What it covers	Where to confirm

Water use permit	CWRM	Withdrawals in designated areas	Current WMA maps

County building desks and the Department of Health can show up later if the well feeds a public water system or a building permit needs a source letter. Those are add-on reviews. They are not the well driller license.

For a mainland split that looks a little like this, read the well driller board in California guide. The forms differ. The two-desk problem does not.

What is a C-57 well drilling contractor license?

C-57 is Hawaii's specialty contractor classification for well drilling. The Contractors License Board sets classes under HRS 444-7.^[6] The C-57 contractor drills wells and does the work the board's current classification list puts in that class.

Read the live classification text on the board packet. Class language gets tweaked. Do not memorize a blog version of the scope.

Hawaii licenses the contracting entity. A responsible managing employee, the RME, qualifies the license with experience and exams. The RME is the person the board can point to when a job goes bad. A one-person shop is usually both the entity and the RME. Hire on as an RME for someone else's company and that company holds the C-57, unless you also hold your own license.

You still need a Hawaii general excise tax license from the Department of Taxation, and a business registration if you operate as an entity.^[12] The C-57 is not a tax account. It is not a CWRM permit either.

Out-of-state drillers get no handshake waiver for holding a mainland card. Hawaii expects you to qualify here. Reciprocity talk is a common wish. Confirm it in writing with DCCA, and do not build a plan on it.

How much does a well driller license cost in Hawaii?

There is no honest single sticker price I can publish for a Hawaii well driller license this year. DCCA posts application, issuance, and renewal fees on the Professional and Vocational Licensing fee schedule, and those numbers move. Confirm the current line items before you write a check.^[9]

Budget by category, not by a fake total. You will see an application fee, a license fee, exam fees paid to the testing vendor, a surety bond premium, general liability insurance, workers compensation if you have employees, and biennial renewal. HRS 444-14 puts Hawaii contractor licenses on a biennial renewal cycle.^[8] Bond face amounts and insurance minimums belong on the current board instruction sheet. I am not going to invent them.

Exam vendor fees are separate from DCCA. You pay the test company to sit the trade exam and the business-and-law exam. Rescheduling costs extra. Fail once and you pay again.

The CWRM well construction permit is a per-well cost, not a license cost. Filing fees, if any, sit on CWRM's current application. Confirm them there.^[4]

Meant how much it costs to hire a well driller in Hawaii? That is a bid, not a board fee. Depth, island, access, basalt versus sediment, casing schedule, and pump size swing the number hard. Nobody has good official data on a current statewide average job price. The honest method is three written bids from licensed C-57 shops, compared line by line.

Skip the package deal from an unlicensed crew that undercuts everyone. That is how people buy a dry hole and a CWRM problem.

How long does it take to become a well driller in Hawaii?

The long wait is experience, not the stamp. The Contractors License Board qualifies a C-57 through an RME who can document supervisory time in the classification. Application packets have long used a four-year supervisory experience standard inside a recent look-back window. Confirm the current year count and look-back on the board's instruction sheet before you count months.^[7]

After you have the time, the clock is application review plus exam seating plus whatever the board asks you to fix. I will not quote a processing time. DCCA owes you no published guarantee, and third-party pages that toss out a fixed number of weeks are guessing. Ask the board for the current review load.

CWRM well permits are a different clock, and they start only when a specific well is proposed. HRS 174C-82 bars well construction until the Commission on Water Resource Management issues a permit.^[2] How many days the commission takes on a complete application is a confirm-with-CWRM fact. Incomplete location maps and missing landowner signatures are what actually burn months.

Starting from zero field time? Plan in years, not months. Already ran jobs as a supervisor for a licensed C-57? You are in the application-and-exam phase. Those are different lives.

No approval timeline in this article is a promise. Boards backlog. Exams fill. Mail gets lost. Build slack.

What experience and exams does Hawaii want for C-57?

You need documented supervisory experience in well drilling, more than time on a crew holding a shovel. The board wants an RME who ran the work. Affidavits, pay records, and letters from licensed contractors carry more weight than a story.

Confirm the exact experience formula on the current Contractors License Board application publications.^[7] That packet is the document that matters, not a summary.

Expect a trade exam for the classification and a business-and-law exam. The board names the testing vendor on the current application. Vendors change over the years. Do not lock a study book to a dead brand.

Study Hawaii contractors law in chapter 444 and the CWRM well standards together. The trade exam follows the classification. The field still follows the Hawaii Well Construction and Pump Installation Standards and the well rules under the water code once you are on a hole.^[3][4]

People with strong drilling time and weak paperwork fail the application, not the exam. Get your experience certificates filled out early. Call former employers while they still remember you.

Oilfield or geotech boring time? Ask the board in writing whether it counts toward C-57. Do not assume.

What well construction permits does CWRM require?

You need a Commission on Water Resource Management well construction permit, a pump installation permit, or the combined form the commission is using on the date you apply, before you start that work. HRS 174C-82 requires the permit first.^[2][4]

Apply on CWRM's current well construction and pump installation permit application. The form wants well location, tax map key, landowner consent, proposed depth, casing, use, and the licensed contractor. Leave the contractor line blank or list an unlicensed name and expect a bounce.

A well construction permit is not a water use permit. Construction permission is about how the hole is built and how the aquifer is protected. A water use permit is about taking water in a designated water management area. You can hold one and still lack the other.

CWRM posts the Hawaii Well Construction and Pump Installation Standards next to the statutory mandate in HRS 174C-84.^[3][4] Read those before you draw a casing schedule. Island geology is not a reason to freelance the annular seal.

Start the permit while you are still pricing the job. Owners will pressure you to just start the pad. That is how crews get stopped in the field.

What reports do Hawaii well drillers have to file?

After the hole is built, Hawaii wants a well completion report. CWRM's well construction program collects construction completion and pump installation completion paper on the current forms.^[4] Use those forms, not a homemade spreadsheet, when you file with the commission.

Grout intervals, casing depths, water levels, yield tests, and as-built locations are the guts of that file. If your field notes are a greasy scrap in the doghouse, the report will be late and wrong.

This is one place a physical logbook earns its keep. WellDrillerPath publishes a $179 one-time Well Board + Grout-Log Kit at /start for crews who want that field paper in one binder. CWRM's own completion forms still control what you file. The kit does not replace the commission's report.

File on time. A well that exists in the ground but not in CWRM's files becomes a problem when the owner sells the property or applies for a pump later.

Abandoning a well has its own paper trail under the water code and the well standards. Do not walk away from a bad hole without asking CWRM what they want for abandonment.^[4]

What are the Hawaii well construction standards?

HRS 174C-84 requires the commission to adopt minimum well construction and pump installation standards to protect water resources and prevent waste.^[3] Those standards apply statewide. They are published as the Hawaii Well Construction and Pump Installation Standards.

The February 2004 standards document is the edition crews still work from unless CWRM has posted a replacement on the well construction page. Confirm the edition before you stamp a drawing.^[4]

The standards cover siting, casing, annular space, grout seals, disinfection, pump installation, and unused wells. Volcanic rock does not cancel the seal. Lava tubes and clinker zones are why the seal exists. USGS groundwater mapping for Hawaii describes those volcanic-rock aquifers in plain terms, which helps when an owner asks why the casing schedule looks expensive.^[13]

I would not buy leftover casing from a different island job and hope it matches the permitted design. Match wall, diameter, and material to what CWRM already saw.

County setback rules and Department of Health drinking-water rules can be tighter for some uses. The state well standard is the floor, not the only book on your truck.

Do you also need a water use permit to drill?

Sometimes. In a designated water management area, a water use permit is required to withdraw water. HRS 174C-48 puts that permit on withdrawals, diversions, impoundments, and consumptive uses in those areas.^[5]

Oahu has designated groundwater areas. Other islands have designated areas too. The list changes when the commission designates or the facts change. Check CWRM's current designated water management area maps before you tell an owner they only need the well permit.

Outside a designated area, the well construction permit and the C-57 license are still in play. You do not skip CWRM because the aquifer is not designated.

A water use permit is the owner's problem as much as the driller's. Still, a well driller who ignores it drills a hole the owner cannot lawfully pump. That phone call is ugly. Put the WMA check in your proposal.

Public water systems bring in the Department of Health Safe Drinking Water Branch, another layer. Private household wells sit outside that federal public-system net, which EPA explains on its private-well pages.^[10] Federal rules treat a system with 15 service connections or 25 people at least 60 days a year as a public water system.^[11] That is not a C-57 issue. It is a reason your client may need DOH review.

What bond, insurance, and business paper sit under the license?

The C-57 application asks for proof the board currently wants. That usually means a contractor license bond, liability insurance, and workers compensation if you have employees. Dollar amounts belong on the live instruction sheet. Confirm them.^[7]

You also need a general excise tax license. Hawaii taxes gross receipts under the GET, and the Department of Taxation issues that license.^[12] Operating without it is its own mess.

Register the entity with DCCA Business Registration if you are not a sole proprietor using only your legal name. The contractor license and the business registration are different DCCA desks.

I would not cheap out on liability coverage just because the bond face amount looks small. One bad well on a hillside lot will exceed a minimum bond. The bond protects claimants the way the statute designed it. It is not a full insurance program.

Keep certificates current. Lapsed workers comp during a claim is how small shops die.

Work on federal land or military jobs and you can expect extra insurance endorsements. Those are contract terms, not board terms.

How do Hawaii well driller rules compare with other states?

Hawaii is stricter than people expect for a small market. You carry a contractor board license and a statewide water commission permit on every new well. Some mainland states fold well driller licensing into the water agency only. Others also split contractor licensing and well standards, just with different forms.

The experience-plus-exam contractor model looks more like other DCCA trades than like a water-well card issued by a health department.

Fees and timelines do not fit a single chart across states, because each board posts its own numbers and changes them. Hold a card in another state? Read that state's board page, then read Hawaii's. Do not assume the months transfer.

Useful next reads if you are comparing paper paths: well driller board in Alaska, well driller board in Arizona, well driller board in Florida, well driller board in Colorado, well driller board in Idaho, well driller board in Georgia, and well driller board in Alabama.

Hawaii's geology is the other difference. Basalt, clinker, and perched water make a Florida casing habit a bad plan here. Follow the Hawaii standards, not your last mainland job.^[4][13]

What should you confirm with the board before you apply?

Call DCCA PVL Contractors License Board and confirm the current C-57 application packet, fee schedule, exam vendor, experience affidavit form, bond wording, and renewal cycle.^[7][9]

Call CWRM well construction staff and confirm the current permit application, any filing fee, the active edition of the well standards, completion report forms, and whether your site sits in a designated water management area.^[4][5]

Confirm how that island wants the file delivered. Some correspondence still wants wet ink. Some accepts electronic filing. That changes. Ask.

Confirm whether your proposed RME's out-of-state time will count. Get the answer in writing.

Confirm GET licensing with Taxation and entity status with Business Registration.^[12]

I would not file a half-blank application to get in line. Incomplete files sit. Complete files move.

Frequently asked questions

Do you need a license for well driller in hawaii?

Yes. Contracting well drilling or well pump installation requires a C-57 license from the DCCA Contractors License Board. Each well also needs a CWRM well construction or pump installation permit before work starts. A mainland card does not replace those two Hawaii papers. Confirm current application steps with both agencies.

How much does well driller cost in hawaii?

License cost is a stack of DCCA fees, exam vendor fees, bond premium, and insurance, plus biennial renewal. Those dollar lines change. Read the current PVL fee schedule. Hiring a crew is a separate bid driven by island, depth, and geology. There is no official statewide job price I trust. Get written bids from licensed C-57 contractors.

How long does well driller take in hawaii?

Getting qualified usually takes years of supervisory field time before you even apply. After that, application review and exam seating depend on the board's current load. CWRM well permits are per hole and start only when the application is complete. Nobody should promise you a stamp date. Ask DCCA and CWRM for current review expectations.

What is the C-57 license in Hawaii?

C-57 is the specialty contractor classification the Contractors License Board uses for well drilling. Hawaii licenses the contracting entity through a responsible managing employee who shows qualifying experience and passes the exams the board currently requires. Read the live classification text in the board packet. Do not treat a blog summary as the scope of work.

Who issues well construction permits in Hawaii?

The Commission on Water Resource Management in DLNR issues well construction and pump installation permits. HRS 174C-82 says work may not start until that permit is in hand. DCCA does not issue this permit. Send location, tax map key, landowner consent, and the licensed contractor information on the current CWRM form.

Is there a separate well driller board in Hawaii?

No. Hawaii splits the job. The DCCA Contractors License Board handles who may contract as a C-57 well driller. CWRM handles whether a specific well may be built and how it must be constructed. County building desks and the Department of Health can add reviews later. Start with DCCA and CWRM, not a county counter.

Do I need a water use permit to drill a well in Hawaii?

Only if the withdrawal sits in a designated water management area, where HRS 174C-48 requires a water use permit. That paper is separate from the well construction permit. Outside a designated area you still need the construction permit and, if you are contracting, the C-57 license. Check CWRM's current WMA maps for the tax map key.

Can I use an out-of-state well driller license in Hawaii?

Not as a substitute for Hawaii paper. You still need to qualify a C-57 with the Contractors License Board and pull CWRM permits on Hawaii wells. Ask DCCA in writing whether specific out-of-state supervisory time will count toward the RME experience showing. Do not mobilize a mainland rig on a handshake.

What is a well completion report in Hawaii?

It is the as-built paper CWRM collects after well construction and after pump installation. Expect grout intervals, casing depths, water levels, yield notes, and location data on the commission's current forms. File it. A well that exists only in the ground will haunt the owner at sale or when a later pump permit is needed.

How often does a Hawaii C-57 license renew?

HRS 444-14 puts contractor licenses on a biennial renewal cycle. The exact due date, late penalties, and current renewal fee belong on the live DCCA PVL fee schedule and renewal notice. Confirm those before you let a card lapse. A lapsed C-57 does not keep a CWRM well permit alive by itself.

Does a private home well need Department of Health approval?

A single-home private well is generally outside the federal public water system definition. If the source serves 15 service connections or 25 people at least 60 days a year, it is a public water system under 40 CFR 141.2 and Hawaii DOH Safe Drinking Water Branch review applies. CWRM well permits still apply either way.

Where do I check if a Hawaii well driller is licensed?

Use the DCCA Professional and Vocational Licensing license search and ask for the C-57 number in writing. Then ask for the CWRM well construction permit number on that specific hole. A business card and a truck are not proof. If either number is missing, stop before you pay a deposit.

What happens if I start drilling before the CWRM permit arrives?

HRS 174C-82 forbids starting well construction or pump installation without the commission permit. CWRM can stop the job and you can create a hole the owner cannot lawfully finish or pump. Owners will push you to start the pad anyway. Do not. Wait for the permit on that tax map key.

Do pump installers need the same Hawaii license as drillers?

Pump installation on a well is inside the CWRM permit scheme, and contracting that work still runs through the Contractors License Board classification rules. Read the current C-57 scope and any related pump class the board lists. Pull the pump installation permit CWRM wants before you set the bowl assembly. Confirm both desks if your shop only hangs pumps.
