TL;DR
Idaho runs no separate well driller board. The Idaho Department of Water Resources licenses drillers, operators, and companies under Idaho Code 42-238 and IDAPA 37.03.10. You need that license (or operator status under a licensee) to construct, modify, or decommission a well. Budget twenty-four months of experience, an exam, a $20,000 bond, and start-card paper on every hole. Confirm current fees with IDWR.
Do you need a license for well driller in Idaho?
Yes. If the hole meets Idaho's definition of a well, you need an Idaho Department of Water Resources well driller license, or you work as an operator under a licensed well driller. Idaho Code 42-238 is the statute. [1] IDWR issues the paper. There is no broad landowner pass that lets you drill your own drinking-water well and skip the license.
People type "well driller board in Idaho" and expect a contractor board with appointed members. You will not find that. You will find IDWR well staff applying Title 42 and two thick rule chapters.
Idaho Code 42-230 and the well construction rules treat a well as "an artificial excavation or opening in the ground more than eighteen (18) feet in vertical depth below land surface by which ground water of any temperature is sought or obtained." [3] [5] If your hole fits that sentence, the license rules attach.
Construct, modify, and decommission all count. Deepening an old casing string is not a freebie. Pulling a well and sealing it is not a freebie. An operator permit is not a workaround. An operator works under the responsible charge of a licensed well driller. [4] [6]
Here is my rule. Do not start a borehole because a forum said owner-built wells are fine. Email IDWR with depth, purpose, and method if you think you have an edge case. Some geotech holes and some very shallow excavations sit in a gray band. Get the answer in writing before the bit turns.
The Idaho path is a credential plus job-by-job paper. It is not a handshake with the county.
Who actually runs the well driller board in Idaho?
IDWR runs it. No standalone Idaho Well Driller Board sits apart from the water agency. The director of the Department of Water Resources issues well driller licenses, operator permits, and company licenses under Idaho Code 42-238. [1] [6]
The licensing detail lives in IDAPA 37.03.10, the Well Driller Licensing Rules. [4] How you build the hole lives in IDAPA 37.03.09, the Well Construction Standards Rules. [5] [10] Those two PDFs are the board, for practical purposes.
Do not call the Division of Occupational and Professional Licenses. DOPL handles a long list of Idaho trades. Well drilling is not on that list. Calling DOPL wastes a day.
Staff sit with the wells program. There is no separate examining panel that meets quarterly to vote you in. That is good and bad. Good: one agency owns the start card, the well log, and the license. Bad: you cannot charm a board hearing when your experience affidavits come up thin. The rule text wins.
I treat the current IDAPA 37.03.10 PDF and the current IDWR application as the only documents that matter. Secondary blogs go stale. The rule file on adminrules.idaho.gov is what a field inspector can hold up.
What well driller licenses does Idaho issue?
Three credentials. A company license for the firm, a licensed well driller credential for the person in responsible charge, and an operator permit for the hands who work under that licensee. [4] [6] You do not pick one at random. The company cannot legally construct a well unless a licensed well driller is in responsible charge. The operator cannot legally freelance.
That split surprises people who came from a state with a single "well contractor" card. Idaho separates the firm, the person who can hold responsible charge, and the person on the deck.
| Credential | Who holds it | What it lets you do | Typical gate |
|---|---|---|---|
| Company license | The drilling firm | Bid and construct wells as a company | Designated licensed well driller plus company bond and application |
| Licensed well driller | An individual | Responsible charge of construction, modification, decommission | Experience, exam, individual application, bond as required |
| Operator permit | An individual | Work on wells under a licensed well driller | Operator application through IDWR, not a substitute license |
If your only licensed well driller quits on a Friday, the company does not get a courtesy week. Stop turning until another licensee is in charge and the IDWR paper matches the truck.
Get the operator permit first. Let a licensed company carry the bond while you build months. Buying a used rotary and then hunting a license is how people stall a whole season.
How do you apply for a well driller license in Idaho?
You download the current IDWR applications, prove the experience the rule asks for, sit the exam IDWR schedules, file the bond the rule names, and pay whatever fee is printed on the form you actually submit. [4] [7] Confirm every blank with the wells program. I will not invent a processing clock or a fee.
Start on the IDWR well driller licensing page, then the applications and forms page. [6] [7] Use this week's PDF. Old copies circulating in shop binders are how people mail the wrong bond wording.
Expect experience affidavits, not a resume. IDWR wants someone who can swear you were on wells, not in the yard welding skids. If your months split across two companies, get both to sign. Gaps look worse than a short letter that tells the truth.
The exam is an Idaho exam. It tracks IDAPA 37.03.09 and 37.03.10, plus how start cards and well reports work. [4] [5] [8] A generic national quiz is weak prep. Read the construction standards like you will argue a seal interval with an inspector. Because you will.
IDWR tells you when and where the exam runs. Do not assume a walk-in in Boise. Do not assume a retake next week if you fail. Confirm both.
No one can honestly promise you will be licensed by a date. Application review, exam seating, and bond issuance each have their own queue. Plan the work as if the card is not in your pocket until IDWR says it is.
How much does well driller cost in Idaho?
Two different bills get mixed up in that question. One is the cost to become a well driller. The other is the cost to hire a crew to drill a well. Neither has a single official price list that stays honest for a year.
On the license path, budget an application fee, any exam fee, a surety premium on the required bond, and later the continuing education you need to renew. [4] [7] [9] IDAPA 37.03.10 sets the well driller bond at $20,000. Confirm the current penal sum on the application you file, because rules get amended. [4] I will not publish a license fee in dollars. The number on this week's IDWR form is the only number that counts.
The bond premium is usually a small percent of that $20,000, paid to a surety, not to IDWR. Shop two bond houses. Do not buy extra "compliance packages" from a website that is not IDWR.
On the hiring side, Idaho publishes no statewide residential well price. Depth, diameter, casing, basalt versus sand, access, and whether the bid includes the pump swing the number hard. The eastern Snake River Plain aquifer is a basalt system. Bits and days disappear in rock that a Treasure Valley sand job never sees. [12]
Get two or three bids from people on the current IDWR licensed list. [6] Ask for the start card number before they mobilize. If a bidder shrugs at the start card, hang up. A cheap per-foot number from an unlicensed truck is not a savings. It is a hole you may have to rebuild.
The pump, pitless, pressure tank, and electrical work are often a second ticket. Wiring is electrical work. Do not assume the well license covers the panel. Confirm who pulls that permit.
Waste of money: paying a middleman to "handle the board" on a short form you can file yourself. Also a waste: a national certificate sold as if it replaced the Idaho license. It does not. [1] [6]
How long does well driller take in Idaho?
The long pole is experience, not the afternoon you spend on the application. IDAPA 37.03.10 requires a minimum of twenty-four months of well drilling experience for an original licensed well driller credential. [4] Confirm the current wording and what counts as full-time months before you quit a job to "go independent."
Those twenty-four months are why a smart first year is an operator year, not a company-owner year. The operator permit is the legal way to be on the hole while the clock runs. [4] [6]
After the months are real, time is exam date plus IDWR review plus bond issuance. I have no honest published turnaround to quote for that review. Anyone who sells you a guaranteed week is guessing. Confirm current seating and review practice with the wells program when you are ready to file.
Building a house well, once you are licensed and the start card is in, is a field schedule. Some holes finish in a couple of days. Basalt, lost circulation, or a collapsed sand interval can eat a week or more. That is drilling time, not licensing time. Do not confuse the two when a customer asks "how long."
Asking how long until you can legally take your first job as the licensee of record? Plan in years, not weeks. Twenty-four months of documented drilling, then paper. That is the honest Idaho timeline.
What experience and exam does Idaho require?
Documented well drilling experience, then a written exam IDWR administers. IDAPA 37.03.10 sets both. [4] Read the current experience subsection word for word. Shop talk about "they count helper time" is no substitute for the rule.
IDAPA 37.03.10 requires "a minimum of twenty-four (24) months" of well drilling experience for an original licensed well driller credential. [4] I would only count months I can prove with affidavits, well reports that show my name in the crew, and a supervisor who still answers the phone. If you spent a winter in the shop, do not call it a drilling month.
The exam follows Idaho paper. Construction standards, licensing rules, start cards, well reports, sealing, and abandonment all show up, because that is the job. [5] [8] [10] Study IDAPA 37.03.09 and 37.03.10. Then study the current start-card instructions. Then go back to the seal intervals.
Confirm the passing score and retake rules with IDWR when they seat you. I will not invent a cutoff. Bring the rule PDFs. Leave the national trivia deck at home.
Idaho does not owe you credit for another state's card. Some applicants get partial recognition of out-of-state months. That is a facts-and-affidavits question, not a compact. Ask IDWR in writing and attach the other state's license packet. Compare the paperwork with states like the well driller board in colorado or the well driller board in arizona only after you know what Idaho will actually accept.
What bond, CE, and renewal does IDWR expect?
A bond before the license is worth anything, continuing education before you renew, and a renewal on the cycle in IDAPA 37.03.10. [4] [9] Confirm dates and credit types on the current CE page. Do not trust a flyer in a motel meeting room.
IDAPA 37.03.10 sets the well driller bond at $20,000. [4] Confirm the current penal sum, the exact obligee language, and whether the company and the individual each need paper. A bond that names the wrong person is a pretty PDF and an incomplete application.
IDAPA 37.03.10 also requires fourteen continuing education credits during each two-year licensing period for licensed well drillers. [4] [9] Confirm that number on the current rule and on IDWR's CE list before you pay a provider. Credits that are not accepted are just a receipt.
Take IDWR-listed courses that actually teach Idaho seals, reports, and abandonment. A generic safety seminar might be fine if IDWR listed it. If they did not list it, skip it.
Renewal is not automatic because you still own a rig. File on the cycle the rule names. Confirm the current expiration pattern with IDWR. Work after a lapse is unlicensed work. That is a bad way to test enforcement.
What start cards and well reports do you file?
A start card (the drilling permit) before construction, and a well report after the hole is done. Idaho Code 42-235 is the permit statute. [2] IDWR's start-card pages are the instructions you follow this week. [8] The license does not replace the start card. The start card does not replace the license.
File the start card before you begin construction. Not after the neighbor calls. Not when you get back to the shop. If IDWR's current process is electronic, use that portal. If a well type still needs a different permit path, use that path. Injection wells are not a casual start-card job. [13]
The well report is the permanent record of depth, casing, seals, lithology, and yield. IDAPA 37.03.09 and the wells program tell you what belongs on it. [5] [10] Late logs are how clean jobs turn into compliance files.
Grout intervals have to match what you actually placed, not what would have looked tidy. If you lost circulation and changed the seal plan, write what happened. Inspectors can read a messy truth. They cannot fix a polished fiction.
Want a shop-level checklist for start-card fields and grout notes? WellDrillerPath sells a $179 one-time Well Board + Grout-Log Kit at /start. It is paper organization. It is not an Idaho license and it does not move IDWR.
Modification and decommission jobs need paper too. Abandonment is not "fill it and forget it." The construction standards say how a well comes out of service. [5] [10]
What well construction rules can fail an Idaho job?
IDAPA 37.03.09 can fail it, even when your license is current. [5] [10] Casing, annular seals, sanitary isolation distances, and abandonment method are the usual fight. Read the current PDF before you stake the hole. County health can add more. The stricter number wins on the ground.
I will not recite setback feet from memory. The construction standards list minimum separation distances. Those numbers move when the rule moves. Pull the current 37.03.09 file the morning you lay out a well near a septic drainfield, animal yard, or chemical storage.
Low-temperature geothermal water is not a novelty in parts of Idaho. If the water is hot enough to trip Idaho's geothermal thresholds, extra rules can attach. Confirm temperature handling with IDWR before you advertise a "hot well" special.
After you leave, the owner still has water-quality work. Idaho DEQ's private well pages cover testing and what a private well is not. It is not a public water system with DEQ on the tap every month. [11] Tell the owner that plainly. A clean start card does not mean the first glass is safe.
Basalt, caving sands, and artesian conditions each have construction answers in the standards. If you have not built that kind of hole, do not invent a method on the customer's nickel. Call someone who has, or stay off the bid.
What happens if you drill without an Idaho license?
You are breaking Idaho Code 42-238. [1] IDWR can treat it as unlicensed construction. The statute is the enforcement hook for license actions and penalties. A start-card violation stacks on top when you also skipped the permit. [2] [8]
Do not test this. "The landowner said I could" is not a defense. "I have a card from another state" is not a defense. "It was only a deepening" is not a defense if the hole is still a well under 42-230. [3]
Customers get hurt twice. They paid for a hole that may have to be reconstructed by a licensed crew. They also own a well that may be hard to sell when the log is missing or the seal is wrong. [11]
If you already drilled and you know the paper is wrong, call IDWR before they call you. That is uncomfortable. It is still better than waiting for a complaint.
Hiring tip for owners: verify the company and the licensed well driller on IDWR's current roster before a truck enters the yard. [6] Ask for the start card number. Write both down.
How does Idaho compare with other state well driller boards?
Idaho is an IDWR shop, not a general contractor board. Experience, a state exam, a bond, and a start card on every well are the spine. [1] [2] [4] Neighboring and far states split those jobs across different agencies. Compare the paper, not the decal on the door.
If you might work winters elsewhere, read the well driller board in california and the well driller board in alaska next. Island and desert rules do not copy Idaho's 18-foot well definition or IDWR start cards. The well driller board in hawaii is a different water agency problem.
For a second look at how other states price and staff a board, the well driller board in alabama, the well driller board in arkansas, and the well driller board in florida show contractor-board models that Idaho simply does not use.
Stay licensed in Idaho first if this is home. Reciprocity talk is cheap. Affidavits are work.
WellDrillerPath is an independent publisher, not a law firm and not a service company. Confirm fees, exam dates, bond language, and processing with IDWR. No article can approve you or time your card. If you still want the paper kit after you read the rules, it is at /start.
Frequently asked questions
Do you need a license for well driller in Idaho?
Yes. Idaho Code 42-238 requires a licensed well driller (or an operator under that licensee) to construct, modify, or decommission a well. IDWR issues the credentials. Landowners do not get a broad self-drill exemption for a normal water well. Confirm odd shallow or geotech holes with IDWR before you turn.
How much does well driller cost in Idaho?
License-path cost is an IDWR application fee, exam cost, bond premium on the rule bond, and later CE. Confirm every dollar on the current form. Hiring a crew is a separate bid. Idaho publishes no official residential well price. Depth, basalt, casing, and the pump package drive the number. Get bids from currently listed licensees.
How long does well driller take in Idaho?
Plan on twenty-four months of documented drilling experience before an original licensed well driller credential, then exam and IDWR review. Confirm what months count under current IDAPA 37.03.10. There is no honest public guarantee of application turnaround. Field time to drill one house well is days to a couple of weeks, not the licensing clock.
Can a landowner drill their own well in Idaho?
Not as a general rule. If the excavation is a well under Idaho Code 42-230 (more than 18 feet, seeking ground water), 42-238 expects a licensed well driller or an operator under one. Do not trust shop talk about owner-built wells. Ask IDWR in writing if you think your hole is outside the definition.
Is there a well driller apprenticeship in Idaho?
Idaho's practical path is the operator permit under a licensed well driller and a company license, then twenty-four months you can prove, then the licensed well driller exam. That is not a separate state apprenticeship board. Get the operator paper filed before you run a deck. Log every hole as if IDWR will ask.
Does Idaho accept another state's well driller license?
Do not assume yes. Idaho runs its own license under 42-238 and IDAPA 37.03.10. Out-of-state months or a card from elsewhere may help an experience review, or they may not. Ask IDWR in writing and attach the other state's license, exam, and work history. Until IDWR says so, you are not licensed in Idaho.
How do I check if an Idaho well driller is licensed?
Use IDWR's well driller licensing pages and the current licensed roster they publish. Match the company name and the licensed well driller who will be in responsible charge. Then ask for the start card number before mobilization. A business license or a truck decal is not an IDWR well driller license.
What is a start card in Idaho?
It is the well drilling permit you file with IDWR before construction starts. Idaho Code 42-235 is the permit statute. The well driller license does not replace it. File it first, drill second, then submit the well report. Injection and some special well types can sit on a different permit path. Confirm the current portal with IDWR.
How deep is a typical Idaho well?
There is no single typical depth. Valley alluvium, mountain benches, and Snake River Plain basalt produce very different holes. USGS work on the eastern Snake River Plain aquifer is a reminder that much of southern Idaho is a rock problem, not a sand problem. Bid from logs near the site, not from a statewide average that does not exist.
Do I need a separate license for geothermal or injection wells?
You still need the well driller credentials for work that meets Idaho's well definition. Injection wells also sit in IDWR's injection well program and federal UIC rules. Hot water can trip extra Idaho geothermal handling. Confirm well type with IDWR before you bid. A normal start card is not always the right first paper.
How often do Idaho well driller licenses renew?
IDAPA 37.03.10 uses a two-year licensing period and requires fourteen CE credits in that period for licensed well drillers. Confirm the current expiration dates and credit rules with IDWR before you let a card lapse. Renewal is a filing, not an automatic thank-you for still owning a rig.
Where is the Idaho well driller exam given?
IDWR sets the time and place when they accept your application. Do not assume a standing walk-in at the Boise office. Do not assume a retake date. Ask the wells program when you file and show up with the current IDAPA 37.03.09 and 37.03.10 text, not a national trivia deck.
Can an operator run a rig without the licensed driller on site?
An operator works under the responsible charge of a licensed well driller. That phrase is defined in IDAPA 37.03.10, and it is not a free pass to freelance. Confirm the current responsible-charge language with IDWR. If the licensed well driller leaves the company, stop until another licensee is designated.
Who should I call, IDWR or DOPL?
Call IDWR. The Idaho Department of Water Resources licenses well drillers, operators, and companies and takes start cards and well reports. The Division of Occupational and Professional Licenses is the wrong agency for this trade. If a website sends you to DOPL for a well driller card, close it and go to idwr.idaho.gov.
