TL;DR
Yes. To drill in Hawaii you need a C-57 well contractor license from the Contractors License Board and a well construction permit from the Commission on Water Resource Management before the bit turns. Statute sets a four-year supervisory experience floor inside the last ten years. Fees and board times change. Confirm both with DCCA and CWRM. Each well needs its own permit.
Do you need a license for well driller in Hawaii?
Yes. If you contract to drill, alter, repair, or abandon a water well in Hawaii, or you install the well pump, you need a C-57 well contractor license from the Contractors License Board. You also need a well construction or pump installation permit from the Commission on Water Resource Management before work starts. A mainland card does not substitute.[1][3]
HRS 444-9 is blunt. "No person within the purview of this chapter shall act, or assume to act, or advertise, as a 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]
That covers advertising. If the door says you drill wells, the board treats you as holding yourself out.
The license sits on the contracting entity. Helpers do not each pull a C-57. You need a responsible managing employee who actually qualifies. In a one-person shop, that is you.
CWRM will not treat an unlicensed contractor as the builder of record. The water code and the contractors chapter stack. Skip either one and you have a hole you cannot legally finish.[3][4]
Do not test an owner-builder theory on a live well. Chapter 444 has a narrow owner-builder path for some building work. Well construction is also groundwater work under chapter 174C. Call CWRM before anyone turns a bit on your own land.
If you are comparing paper paths, well driller license in California and well driller license in Alaska run on different boards. Hawaii is a contractor-board license plus a water-commission permit.
What is a C-57 well contractor license in Hawaii?
C-57 is the Contractors License Board specialty classification for well contracting. It is the card CWRM looks for when you apply to construct a well or install a pump. It is not a county card. It is not a federal card.[2][3]
Scope is well work. Water wells, casings, screens, well pumps, related equipment, pump houses. It does not turn you into an electrician. Power to the panel still needs a licensed electrician. Advertise septic, grading, or general building off a C-57 and you are outside class.
Hawaii licenses other contractor classes too. A plumbing class does not let you drill. Well work is its own specialty.
CWRM can adopt licensing rules for well construction and pump installation contractors under HRS 174C-86. In practice the permit desk wants a current C-57. Confirm the current acceptance list with CWRM when you file. Rules and forms get revised.[5]
Hold the license in the name that will sign contracts. Form an LLC later and keep bidding as the old sole prop, and you have a paperwork mess. Fix the entity first.
| Paper | Who issues it | When you need it |
|---|---|---|
| C-57 well contractor license | DCCA Contractors License Board | Before you contract or advertise well work |
| Well construction permit | CWRM | Before construction starts, each well |
| Pump installation permit | CWRM | Before pump work, unless combined on the same permit |
| Water use permit | CWRM | Before withdrawal in a designated water management area |
| GET license | Department of Taxation | Before you take gross receipts |
How do you get a C-57 well contractor license in Hawaii?
You apply to the Contractors License Board at DCCA, not to CWRM. CWRM does the well permits. DCCA does the contractor license.[2]
Statute sets the experience floor. HRS 444-11 says the board shall not license a person unless that person "has had, within the past ten years immediately preceding the filing of an application, not less than four years of supervisory experience in the field for which the applicant has applied."[2]
Read that twice. Supervisory. In the last ten years. In well work, not in a loosely related trade you hope they accept. The board can ask for pay records, contracts, affidavits, and project lists. Keep a dated log of every well you ran, depths, method, and who signed your checks.
HRS 444-11 requires not less than four years of supervisory experience in the last ten years for a Hawaii contractor license.[2]
Education credit is a board-rule question. Do not invent a formula. Ask the current application packet whether school time offsets field time. If the packet is silent, do not assume it does.
You will sit exams. Hawaii contractors take a business and law exam plus a trade exam for the class. Schedule and candidate bulletins come through the board's testing vendor. Confirm the current vendor, cut score, and retake rules with DCCA. Study the business and law book first. That exam drops more applicants than they expect.
The packet also wants financials, a credit report, and entity papers if you are not a sole proprietor. Hawaii maintains a contractors recovery fund under HRS 444-26, and the application involves fund fees the board sets. Confirm every current dollar on the DCCA fee schedule before you write a check.[6]
An RME who already holds C-57 can qualify a new entity. That is a common path for a driller who wants an LLC without waiting four more years. The RME has to be actively in charge of the well work. Paper RMEs get people in trouble.
After the C-57 is live, you still cannot drill. You pull the CWRM permit next.
How much does well driller cost in Hawaii?
Two different bills get mixed up. One is the cost to get legal. The other is the cost to put a well in the ground.
License-side costs are real, but they are not the big number. You pay DCCA application and license fees, testing-vendor exam fees, a credit report, possible bookkeeping work on the financial statement, entity registration if you form one, recovery-fund amounts, and a GET license. Those line items change. Confirm every dollar on the current DCCA contractor fee schedule and the testing bulletin. I will not invent a fee the board may have amended last month.[6][10]
Insurance and payroll tax outrun the license fees in year one if you have a crew. Workers compensation in Hawaii is not optional once you have employees. General liability is what landowners and water systems ask for before you stage a rig.
The well itself is a different market. Hawaiian wells often go through hard volcanic rock. Basal lenses, dike-impounded water, and perched water are not Midwest sand wells. USGS mapped that hydrogeology years ago, and it still dictates rig time.[7]
Nobody publishes a clean, current statewide average price for a completed domestic well that I trust. Island freight for casing and grout, access roads, depth, and whether you are on basalt or valley fill swing the bid. If someone quotes a single typical Hawaii well number on a blog, ignore it. Get three written bids on the same design.
A waste of money: buying a second support truck before you have a C-57, a GET number, and a supplier who can land freight on your island. Paper and supply chain first.
For a well driller Hawaii shop just starting, cash goes to insurance, freight, and idle time waiting on CWRM, not to logo wrap.
How long does well driller take in Hawaii?
The long pole is the experience clock. Four years of supervisory well work inside a ten-year lookback is in the statute. You cannot buy that down with a seminar.[2]
After you file, DCCA review plus exam scheduling plus license issuance is a board process. Times move with their caseload. Confirm current intake with the Contractors License Board. No article should promise you a week or a month. I will not.
CWRM well construction permits are a second clock, and they run per well, not once per career. Do not mobilize the rig while the permit is in the mail. Ask CWRM for current processing guidance when you file. Weather, incomplete location data, and missing landowner signatures all add days. None of that guarantees approval.[3]
Drilling days depend on geology. A shallow valley well and a deep basal well on the same island are not the same job. Build slack into the estimate.
Still accumulating the four years? Stay employed under a licensed C-57 and keep records like you will have to show them. Because you will.
Well driller license in Texas is a different clock and a different board. Do not mix the two calendars.
What does CWRM require before you drill a well in Hawaii?
A well construction permit. Pump work needs a pump installation permit. Some jobs need both. Construction does not start until the permit is issued.[3][4]
HRS 174C-84 directs the commission to adopt well construction and pump installation standards. Those standards cover how the well is built, more than whether you may build it. Casing, grout, annular space, disinfection, and sealing of abandoned wells live in that standards stack. Read the current CWRM standards document before you bid, not after someone has questions.[4]
The application sits on CWRM's well construction program pages. You identify the contractor (your C-57), the location, proposed depth and use, and related well data. Landowner signatures matter. Incomplete tax map key data is a classic bounce.[3]
Designated water management areas add a water use permit question for the person who will actually withdraw water. That is the landowner's problem more than yours, but you will look foolish if you drill a production well that cannot legally be pumped. Flag it in the estimate.[8]
A county grading slip is not a substitute. County paper, if any, sits beside CWRM. It does not replace it.
What happens if you drill in a designated water management area?
The well construction permit is still required. On top of that, HRS 174C-48 says no one may make a withdrawal, diversion, impoundment, or consumptive use of water in a designated water management area without a water use permit from the commission.[8]
The statute is plain. "No person shall make any withdrawal, diversion, impoundment, or consumptive use of water in any designated water management area without first obtaining a permit from the commission."[8]
CWRM publishes the current list of designated groundwater management areas. Oahu has had several for a long time. Molokai and parts of Maui have them too. The list can change. Check the CWRM designated-area page for the tax map key before you bid, not after the casing is on the dock.[9]
You can usually still construct if CWRM issues the well permit. The pumping right is separate. Tell the client that in writing. Drillers get dragged into fights that started as a belief that the well permit was the water right.
Outside a designated area, water use permits under 174C-48 do not apply the same way. Well construction permits still do.[3]
Do you need a separate pump installer license in Hawaii?
You do not pull a second specialty card with a different letter code for pumps if your C-57 already covers well pump installation. Confirm your specific license printout. C-57 is the well contractor class CWRM expects on pump installation permits.[3][5]
You do need a pump installation permit from CWRM before you set the pump, unless CWRM's current rules fold that step into a combined permit for your job. Read the permit you were issued. Combined applications exist. So do pump-only jobs on existing wells.
Electrical work is separate. If you land a submersible and then land the control wiring, the electrical portion is not C-57 work. Use a licensed electrician. Shops that try to just land the leads end up explaining themselves to two boards.
Repair of an existing pump can still trigger the pump installation permit rules. Confirm with CWRM before you pull a stuck column. Emergency language, if any, is in their current rules, not in a forum post.
Can you use an out-of-state well driller license in Hawaii?
No. Hawaii does not let you drill on a California card or a Texas driller license. You need the Hawaii C-57 (or you work as an employee of someone who holds it) and you need the CWRM permit.[1][3]
Some states talk about exam waivers. Whether Hawaii currently waives a trade exam for a specific state is a board question. Confirm in writing. Do not ship a rig based on a verbal claim that they usually accept another state.
Even if the board ever waived an exam, you still file a Hawaii application, pay Hawaii fees, and hold a Hawaii license. The water permit is still local.
Want to run as a consultant and never contract the hole? Stay on that side of the line. The minute you agree to construct, chapter 444 applies.
See well driller license in Arizona if you are mapping multiple western states. The cards are not interchangeable.
What reports and paper do you file after the hole is in?
A well completion report goes to CWRM after construction. Pump installation has its own completion paper when that is the work you did. Deadlines are in the current CWRM rules and on the form. Confirm the number of days. File as soon as the as-built data is clean, not on the last hour of the window.[3][4]
Log what you actually drilled. Lithology, water strikes, casing schedule, grout intervals, yield, water level. If you grouted in lifts, write the lifts. This is where a field grout log earns its keep. WellDrillerPath sells a $179 one-time Well Board + Grout-Log Kit at /start if you want that packet assembled. A lab notebook works if you actually fill it out.
Abandoned or unused wells have sealing rules. Do not walk away from a dry hole without asking CWRM what sealing report they want. An open annulus is how you get a contamination problem with your name on the well tag.
Keep copies for the landowner and for your own file. The next pump job on that well will need the as-built. Agency well indexes are only as good as the reports contractors file.[7]
If the well will serve the public, the Department of Health Safe Drinking Water Branch may have a second packet. Ask DOH before you call the job complete.
What insurance, tax, and county paper sit next to the license?
Get a GET license. Hawaii runs a general excise tax on gross receipts, not a mainland-style sales tax. You apply with the Department of Taxation on the basic business application. File on their current schedule.[10]
Workers compensation attaches once you have employees. Unemployment insurance too. Sole props without employees still think about health coverage, but that is not the contractor board's test.
General liability and auto on the rig are what landowners ask for. Some water utilities set minimums in their contractor packets. Confirm those numbers with the utility, not with a national template.
Counties can add business registration. Honolulu, Maui, Hawaii, and Kauai do not share one clerk. Call the county where the yard sits and the county where you will drill.
A federal EIN is needed if you hire or form an entity. That is IRS, not DCCA.
None of this replaces C-57 or the CWRM permit. It sits next to them.
How to start a well driller business in Texas is a different first-year stack. Do not copy their tax steps. GET is its own creature.
What gets people in trouble on Hawaii well jobs?
Starting the hole before the CWRM permit is in hand. That is the classic one. The water code lets the commission penalize violations, and a continuing offense is counted by the day. Read HRS 174C-15 for the current fine language before you decide a start this week, file next week plan is cute.[11]
Contracting without a C-57 is the other classic. HRS 444-22 is the quiet killer. Fail to get the license before you contracted, and you can be blocked from recovering for the work in a civil action.[12]
"The failure of any person to comply with any provision of this chapter shall prevent such person from recovering for work done, or materials or supplies furnished, or both on a contract or on the basis of the reasonable value thereof, in a civil action, if such person failed to obtain a license under this chapter prior to contracting for such work."[12]
HRS 444-22 can block an unlicensed contractor from recovering payment in a civil action.[12]
So you can do the job, eat the freight, and then lose in court. Do not.
Other pain: working outside C-57 into electrical or civil, advertising before the license prints, using an RME who is not actually running the work, and skipping the completion report so the well never enters the official record.
Cultural and access issues are real on Hawaiian land. TMK mistakes and missing landowner authority delay more jobs than bit failure.
How do you renew a Hawaii well contractor license?
Contractor licenses renew on the board's cycle. Confirm the current expiration month and the online renewal window with DCCA. Do not trust a blog for the year your card dies.
Continuing education, if the board currently requires it for contractors, will be in the renewal notice. Confirm hours and approved providers with DCCA. I will not invent an hour count.
Keep the RME current. If your qualifier leaves, the entity can lose the right to contract until a new RME is accepted. File that change before you bid the next well.
CWRM permits do not renew like a license. Each new well is a new permit. Your C-57 just has to be alive when you apply and when you work.[3]
Insurance certificates and GET filings have their own calendars. Put them on one wall calendar. Missed GET filings cause stupid, avoidable pain.[10]
Let the C-57 lapse and you treat reactivation as a board process. Confirm whether you need a new application or a restoration form. Do not drill in the gap.
What should you do in year one after you get the C-57?
File GET. Buy the insurance people will actually ask for. Set a completion-report habit on day one. Then take one well you can staff and permit cleanly, preferably close to your yard.[10]
Do not chase every island in year one. Freight and ferry time wreck a thin shop. Pick an island, learn that geology, learn that CWRM reviewer pattern.
Keep the field log boring and complete. A binder from the office store is fine if you use it.
Stay inside C-57. Sub the electrical. Write the water-use-permit caveat into every estimate in a designated area.[8]

Frequently asked questions
Do you need a license for well driller in Hawaii?
Yes. Contracting to drill, alter, repair, or abandon a water well, or to install the well pump, takes a C-57 well contractor license from the Contractors License Board. You also need a CWRM well construction or pump installation permit before work starts. Advertising as a well driller without that license violates HRS 444-9. Confirm both filings before you mobilize.
How much does well driller cost in Hawaii?
License-side costs are DCCA fees, exam fees, a credit report, entity paper if you form one, recovery-fund amounts, insurance, and a GET license. Those dollars change, so confirm the current DCCA schedule. Job prices vary by island, depth, and volcanic rock. Nobody publishes a trustworthy statewide average. Get three written bids on the same design.
How long does well driller take in Hawaii?
The statute sets four years of supervisory well experience inside a ten-year lookback before C-57. Board review and exam scheduling sit on top of that. CWRM then times each well permit separately. Confirm current intake with DCCA and CWRM. Do not treat any article as a promise of approval speed.
Is a C-57 the same thing as a CWRM well permit?
No. C-57 is the contractor license that lets you bid and advertise well work. The CWRM well construction or pump installation permit is job-specific permission to build or equip that well. You need both. A live C-57 without a permit is not authorization to turn the bit.
Can I drill my own well on my own land in Hawaii?
Do not assume yes. Chapter 444 has a narrow owner-builder path for some building work, but well construction is also groundwater work under chapter 174C. CWRM expects a licensed C-57 on construction. Call CWRM before anyone turns a bit, even on land you own.
Does Hawaii accept another state's well driller license?
No. You cannot drill on a mainland card. You need a Hawaii C-57, or you work as an employee of a firm that holds one, plus the CWRM permit. Any exam waiver is a board decision. Get it in writing. The water permit is still local even if an exam is ever waived.
Who issues the well driller license in Hawaii?
The Contractors License Board at DCCA issues the C-57 well contractor license. The Commission on Water Resource Management in DLNR issues well construction and pump installation permits and sets construction standards. The Department of Taxation issues the GET license. Those are three different desks.
Do I need a new CWRM permit for every well?
Yes. CWRM permits run per well, not once per career. A new hole needs a new well construction permit. Pump-only work on an existing well needs the pump permit CWRM currently requires for that job. Keep the C-57 current when you apply and when you work.
What experience do you need for a C-57 in Hawaii?
HRS 444-11 sets a floor of four years of supervisory experience in the field, earned in the ten years before you file. The board can ask for project lists and pay records. School credit, if any, is a current board-rule question. Ask the packet. Do not invent a formula.
Can an unlicensed well driller collect payment in Hawaii?
HRS 444-22 can block recovery. If you failed to get the contractor license before you contracted, you may be unable to recover for work or materials in a civil action, even on a quantum meruit theory. You can eat the freight and still lose in court. Get the C-57 first.
Do I need a GET license to drill wells in Hawaii?
Yes if you are in business and taking gross receipts. Hawaii uses general excise tax, not a mainland sales tax. Apply with the Department of Taxation on the basic business application and file on their current schedule. GET does not replace C-57 or the CWRM permit.
What if the well will serve a public water system?
C-57 and the CWRM construction permit still apply. The Department of Health Safe Drinking Water Branch may also review the source if it will serve the public. Ask DOH before you call the well complete. Do not treat a CWRM permit as drinking-water approval.
