How to start a well driller business in Indiana legally

Last updated 2026-08-19

Do you need a license for well driller in Indiana?

Yes. To act as a water well driller in Indiana you need a license from the Indiana Department of Natural Resources under IC 25-39. The same article covers water well pump installers. County well permits and IDEM public-water rules sit on top of that card. They do not replace it.^[1]

People still repeat a national myth that farm wells are unregulated. That is not how Indiana wrote the statute. The license attaches to the person doing the drilling and pump work, not to the size of the farm. Run a drilling machine or take a contract to drill a water well and you are inside IC 25-39.^[1]

Helpers can swing wrenches. The licensed individual is the one the state can discipline. Read the definitions before you put a company name on a truck. A corporation does not hold this card the way some contractor boards work. An individual does.^[1]

You may also need a local permit from a county health department before the bit turns. That is a separate piece of paper. If the well will serve a public water system, IDEM drinking-water rules apply too.

Comparing states? The Indiana path is a DNR resource license, not a building-trades card. The Texas start guide and the Arkansas start guide show how different the paper looks once you cross a line.

Who licenses well drillers in Indiana?

The Indiana DNR Division of Water licenses water well drilling contractors and water well pump installers. You deal with the ground-water program, not the Indiana Professional Licensing Agency. Confirm the current application packet, exam dates, and fee with the Division of Water.^[5]

312 IAC 13 is the rulebook under the statute. Construction, grouting, records, abandonment, and the license process live there. Print it. Tab it. The exam is built on it.^[3]

DNR also keeps the water well record database. Later drillers, health departments, and landowners will see what you claimed you built. Treat every log as a public document, because it is.^[5]

Call the Division of Water before you pay a testing vendor or a national license coach. Indiana is not selling a multi-state card. Fees and forms change. Confirm with the department. Nobody can honestly lock a processing time for you.

What are the Indiana well driller license requirements?

You apply as an individual, sit the department exam, and meet whatever competency and application items 312 IAC 13-2 currently lists. IC 25-39-3 is the license chapter. The administrative code is where the application mechanics live. Read both, then use the current DNR form, not a blog checklist from 2016.^[1][3]

I will not invent an experience year-count or a passing score. Those details belong on the current application and in 312 IAC 13-2. If a website quotes two years without showing the rule section, treat it as stale until you verify.^[3]

The study materials that matter are short. IC 25-39. 312 IAC 13. The well record form. Typical grout and casing details. You do not need a $2,000 exam prep course. You need nights with the rule PDF and time on a rig next to someone who already holds the card.

The department offers the exam on a schedule it controls. Confirm dates with the Division of Water. No article should promise you a sitting next month.^[5]

Bring whatever identification and payment the current notice asks for. If you fail, ask the department how retests work. Do not assume a same-week retake.

How much does well driller cost in Indiana?

The license fee is the small line. Confirm it with the Division of Water, because I will not invent a current board fee. The money that decides whether you actually start is the rig, support trucks, casing stock, insurance, and a yard you can make noise in.^[5]

Used rotary spreads in the Midwest run from the high five figures into the mid six figures, depending on age, depth rating, and whether a mud system or air package is included. A working range people actually pay is about $80,000 to $400,000 or more for a used rotary. Cable-tool machines cost less and still make a living on certain glacial aquifers. Nobody publishes a clean Indiana startup study. Those numbers are market talk, not a government figure.

Insurance is not optional if you want landowners to let you on the place. General liability plus inland marine on the rig is the normal pair. Premiums move with claims history and the value of the iron. Get quotes. Do not guess from a Facebook group.

Business formation through INBiz is a real cost, and it is small next to a compressor. Confirm the current entity filing fee on the Secretary of State side before you write the check.^[8]

A first-year Indiana shop that already owns a used rig and a legal truck still needs working capital for fuel, grout, casing, bits, repairs, and the weeks when the phone is quiet. No rig yet means no startup number. You have a shopping list.

Waste of money: vinyl wraps, a downtown office, and any national certification that Indiana DNR does not ask for.

Cost item	What to expect	Confirm with
DNR license and exam	A board fee, not the real budget	Division of Water
Indiana business entity	A state filing fee	INBiz
Used drilling rig	About $80,000 to $400,000+ on the private market	Sellers and a mechanic you trust
Liability and rig insurance	An annual premium set by underwriters	Indiana insurers
First-year consumables	Casing, grout, bits, fuel, repairs	Suppliers

How long does well driller take in Indiana?

If you already have the field time the current application wants, the remaining clock is application plus exam scheduling plus the time to stand up the business. That runs weeks to a few months. Confirm the exam calendar with the Division of Water. There is no honest public processing promise.^[5]

Starting as a helper? Plan in years, not weekends. The competency path in 312 IAC 13 is built so you learn the work under someone who already holds the license. That is the right order.^[3]

Forming an LLC or corporation on INBiz is the fast part. Days, if your paperwork is clean. The EIN from IRS can be same-day online for most applicants.^[8][9]

Buying a rig, insuring it, and finding a place to park it takes longer than any license form. I have watched people treat the card as the project and then sit half a year waiting on a used machine and a shop lease.

No approval guarantee. No you-will-be-drilling-by-spring line. Weather, parts, and the department's exam dates all move.

Compare that with states that stack extra contractor boards on the water license. The California start path is a different animal. Indiana is slower on iron and land, not on the exam booklet.

Do you need a separate license for pump work in Indiana?

Yes. Indiana splits the work in the same article. Water well pump installer is its own license under IC 25-39. Some people hold both. Some shops keep a licensed driller and a licensed pump person. Confirm with DNR how dual applications work on the current forms.^[1][5]

Pulling a submersible and setting a pitless adapter is more than mechanical work under this statute. Sell turnkey domestic wells and you need to budget for both competencies. House plumbing past a point of connection can also trip local plumbing rules. That is a city or county question, not a DNR one.

Get the driller card first if you are buying a rotary, then add the pump license before you advertise complete systems. Advertising what you are not licensed to do is how complaints start.

What paper do you file after you drill a well in Indiana?

You keep a well record on each well and send a copy to the department. Indiana well-record practice, tied to IC 25-39-4 and 312 IAC 13, is a 30-day submission after completion. Confirm the current form instructions. The Division of Water well record database is where that paper lands. Late logs are how drillers get letters they do not want.^[4][5]

The record is not a marketing brochure. Location, date, depth, formations, static level, casing, grout, screen, yield. Fill it like someone will drill 40 feet away in ten years, because they will.

Grout placement is part of that story. 312 IAC 13 has the construction and sealing rules. If you cannot show what went in the annulus, you do not have a complete job file.^[3]

A field binder beats a pile of damp invoices on the dash. If you want a pre-built board and grout-log packet, WellDrillerPath sells a $179 one-time Well Board + Grout-Log Kit, but a labeled notebook and the official DNR record form work if you actually fill them out.

Give the owner a copy. Keep a copy. File the state's copy. Miss one and you redo it later.

What construction rules apply to Indiana water wells?

312 IAC 13 is the construction code you will actually be judged against. Casing type and depth, annular seal, pitless adapters, disinfection, and abandonment are in that article. Read the grouting and casing chapters twice. Complaint files start there.^[3]

Indiana geology is not one aquifer. Glacial drift in the northern two-thirds behaves differently from the bedrock systems farther south. A shallow sand well and a deeper limestone well are not the same product, and you should price them that way.

Do not invent a statewide typical depth and sell it to a customer. Pull nearby logs from the DNR water well record database before you bid. That database exists so you stop guessing.^[5]

Public water system wells are a different job. IDEM drinking-water staff will care about sanitary construction and sampling for community and noncommunity systems. If you have never built a public-supply well, do not learn on a town's only source.

Abandoned wells you open or replace need proper plugging under the same rule article. Leaving an old casing open next to a new well is how you buy a contamination complaint.

When does a well trigger Indiana's 100,000 gallon registration?

When a facility can withdraw more than 100,000 gallons of ground water, surface water, or both in one day, Indiana calls it a significant water withdrawal facility. That registration is separate from your driller license. Small house wells almost never hit it. Big irrigation and plant wells might.^[6][7]

IC 14-25-7-15 defines a significant water withdrawal facility as "the water withdrawal facilities of a person that, in the aggregate from all sources and by all methods, has the capability of withdrawing more than one hundred thousand (100,000) gallons of ground water, surface water, or ground and surface water combined in one (1) day."^[6]

That is a capability test, not last month's pump run time. Several wells added together can trip it. Registration runs through DNR's significant water withdrawal facility program.^[7]

Your job as the driller is not to file the owner's SWWF paperwork unless you contract to do it. Your job is to know the threshold so you do not shrug when a farmer asks why DNR wants another form. Do the arithmetic with the owner when the pump curve gets large.

What business registrations does an Indiana well driller need?

DNR does not make you a legal business. INBiz and the Secretary of State do the entity filing. Get the current checklist and fee from INBiz before you mail anything. An LLC is what I would use for most small rigs, but that is not legal advice.^[8]

Get an EIN from IRS if you will hire, open a business bank account, or file employment taxes. The IRS says an EIN "is also known as a Federal Tax Identification Number, and is used to identify a business entity." Do not pay a reseller for that number.^[9]

Register with the Indiana Department of Revenue for the tax types that apply to you. Withholding if you have employees. Sales tax if you sell goods or services DOR treats as taxable. Confirm on the business registration pages rather than copying another shop's account list.

Workers' compensation is an Indiana Worker's Compensation Board matter once you have employees. Owner-only shops still need to read the employer FAQs before they assume they are exempt.

Unemployment insurance through the Department of Workforce Development shows up when you have employees. Talk to a payroll service in month one, not after the first wage claim.

Local zoning for a noisy yard with pipe racks is the permit people forget. A rural county may shrug. A town lot will not.

What insurance, safety, and truck rules hit a new Indiana rig?

IOSHA can inspect you. Water well work mixes overhead loads, rotating equipment, silica dust, and electrical pump work. Indiana operates an OSHA-approved state plan. Have a written hazard program that matches the work you actually do, not a copied oilfield binder.^[11]

If the truck that tows or carries the rig has a GVWR of 26,001 pounds or more, you are in CDL territory under FMCSA class rules. Confirm the class and any air-brake endorsement before you buy a tandem that nobody on the crew can legally drive.^[15]

Insurance again. Landowners and general contractors will ask for certificates. No certificate, no farm.

Spend money on guarding, a working kill switch, and silica and hearing controls before you spend it on a new office laptop. Helpers get hurt on pipe and spinning tools. That is the first-year risk.

What do first-year operations look like for an Indiana well driller?

Slow, muddy, and driven by referrals. You bid from nearby DNR logs, you fight glacial cobbles or tight bedrock, and you live or die on whether your grout and casing match 312 IAC 13. File every well record on time. For a small shop, that habit is the whole compliance program.^[3][5]

Seasonality is real. Frozen ground and spring planting both change when people want a well. Keep enough cash to sit.

You will spend more days on service, abandoned-well plugging, and pump pulls than the brochure suggested. That is fine. It pays.

Look at how Tennessee describes the license path or how Alabama starters get papered if you expect to work crews across state lines later. Indiana will not carry those cards for you.

WellDrillerPath is an independent publisher, not a law firm and not a service company. For a structured start checklist, use /start. Still confirm every fee and form with DNR.

What should you skip when you start a well driller in Indiana?

Skip national well driller certification packages that do not name IC 25-39 or 312 IAC 13. Skip buying a brand-new top-head rotary your cash flow cannot feed. Skip hiring three helpers before you have 30 days of booked work.

Do not skip the well record. Do not skip local health permits. Do not skip reading the abandonment chapter before you pull old casing.

Want another state's packet for comparison? The Colorado start guide, the Arizona start guide, and the Texas license page are useful only as contrast. Indiana still wants Indiana paper.

Frequently asked questions

Do you need a license for well driller in indiana?

Yes. Indiana requires an individual DNR license under IC 25-39 to act as a water well driller. Pump installation is a separate license in the same article. County health permits and IDEM public-water rules can also apply. Confirm the current application with the Division of Water before you advertise or sign a drill contract.

How much does well driller cost in indiana?

The DNR license fee is the small cost. Confirm it with the Division of Water. Real money is the used rig (often about $80,000 to $400,000+ on the private market), support trucks, insurance, casing, and grout. Nobody publishes a solid Indiana startup study. Form the business through INBiz and get quotes from insurers before you bid work.

How long does well driller take in indiana?

If you already meet the current application competency items, plan on application time plus whatever exam date the Division of Water is offering. That runs weeks to a few months. There is no public guarantee. Starting as a helper means years. Buying and insuring a rig usually takes longer than the paper.

Is the Indiana well driller exam open book?

Do not trust forum memory on format. The exam is built around IC 25-39 and 312 IAC 13. Confirm the current rules, allowed materials, and sitting dates with the Division of Water. Study the rule PDF and the well record form either way. A paid national prep course is usually a waste.

Can I drill in Indiana on an out-of-state license?

Do not assume an Ohio, Illinois, Michigan, or Kentucky card works. Indiana licenses this work under IC 25-39 through DNR. Ask the Division of Water whether any reciprocity exists on the current application. Until the department says yes in writing, plan to take Indiana's exam and hold Indiana's card.

Do counties also permit private wells in Indiana?

Often yes. Many county health departments issue a local well permit or review setbacks before construction. That permit does not replace the DNR driller license. Call the county where the hole will be, more than the county where your shop sits. Public-supply wells add IDEM on top.

Who gets a copy of the Indiana well record?

Keep a copy, give the owner a copy, and send the state's copy to the Division of Water. Indiana practice is a 30-day filing after completion. Confirm the current form. Those records feed DNR's water well record database, which later drillers and health departments will actually use.

Do I need a license to abandon or plug a well in Indiana?

Treat plugging as licensed well work, not scrap removal. 312 IAC 13 includes abandonment and sealing standards. If you pull old casing or open an unused well, read that chapter first. Confirm with DNR who may file the abandonment record. A sloppy plug next to a new well is how contamination complaints start.

Can a helper run the rig without an Indiana license?

Unlicensed helpers can work. The licensed individual is the person Indiana can hold responsible under IC 25-39. Do not leave an unlicensed helper contracting jobs or running the machine as if they hold the card. Read the statute definitions, then set shop rules that match them.

Are geothermal or monitoring holes under the same Indiana license?

IC 25-39 and 312 IAC 13 are written around water wells and pump work. Closed-loop geothermal and some monitoring boreholes may sit in a gray spot. Do not guess from a Facebook thread. Ask the Division of Water whether your specific hole is a water well before you bid it.

What if I only install pumps in Indiana?

You still need the water well pump installer license under IC 25-39. It is not the same card as the drilling contractor license, though many people hold both. House plumbing past the well connection can also trip local plumbing rules. Confirm dual-license steps on the current DNR forms.

Does Indiana require continuing education for well drillers?

Do not take a national CE vendor's word for it. Read the current renewal section in 312 IAC 13-2 and ask the Division of Water what the renewal form actually wants. If the department does not list a CE hour requirement, skip the paid webinar and spend the time on grout logs.

Where do I confirm current Indiana well driller fees?

The Division of Water and the current application packet. Statute and rule authorize the license. The live fee is on the form. Confirm INBiz entity fees with the Secretary of State and tax accounts with the Department of Revenue. Ignore old dollar figures on blogs.

Can I start as an employee first in Indiana?

Yes, and I would. Work under a licensed water well driller, learn 312 IAC 13 in the field, and keep dates and well records that prove what you did. Then apply as an individual, sit the DNR exam, and form your own shop. Buying a rig before you have that time is how people go broke.
