Water well drilling and pump installation businesses in Indiana

Indiana licenses individual water well drillers and pump installers, not companies. The Indiana DNR publishes a list of the Indiana businesses that employ them, by county. This page lists every business on that list. Filter by county or search by name.

How Indiana licenses well drillers and pump installers

• A license is required. Indiana Code 25-39 requires anyone who operates well drilling equipment or drills wells, and anyone who installs or repairs water well pumping equipment, to be licensed by the Department of Natural Resources. The rule 312 IAC 13 covers drilling, casing and grouting new wells, plugging old ones, and pump installation standards.¹
• One card, one person. DNR issues a single license card that says whether a person is a driller, a pump installer or both. Licenses expire on December 31 of the year they're issued.¹ DNR licenses individuals, not companies, so it says to check that the person (or the person leading a team) is licensed before any work is done or money changes hands, and to ask to see proof of the license.²
• The license holder must be there. DNR says a license is only valid if the licensed person is on site while the work is done.²
• Check a license: call the DNR Division of Water toll-free at 1-877-928-3755.³

Check a license yourself

• Individuals: call the Division of Water at 1-877-928-3755 to confirm a driller's or pump installer's license status.³
• Businesses: DNR's Licensed Water Well Drilling Contractors page has the Indiana list used here and separate lists for contractors based in Illinois, Kentucky, Michigan, Ohio and the rest of the U.S.³
• Labs: the Indiana Department of Health certifies drinking water labs; see its drinking water laboratory certification page and the IDOH lab's well water testing page.

The list

Every business on DNR's Indiana list ("Last Revised: July 2026"), under the county DNR lists it in. DNR says the county is where a home or satellite office is, not a list of counties a business serves, so call to confirm the area they cover. The service types are the "primary services" codes DNR shows for each business, which DNR says to confirm with the business because they can change.² DNR's list has no license numbers, because it licenses people, not businesses; ask for the license number of whoever does the work. We left out the government agency entries on the list. Certified labs and home inspectors: we haven't loaded an Indiana list yet.

Home inspectors and well inspections

A standard home inspection usually doesn't include a full check of the well. If you're buying or selling a home with a well, ask the home inspector whether they do a well flow (yield) test and water sampling, which state-certified lab runs the samples, and whether they look at the well cap, pressure tank and pump controls. Otherwise, hire a licensed well contractor for the well itself and a certified lab for the water. Are you a home inspector? See our well inspection guide for home inspectors.

NGWA (the National Ground Water Association, a private trade group) recommends a yearly well checkup by a qualified water well professional: a flow test, checks of the water level, pump, pressure tank and switch, a sanitary and code check, a coliform bacteria and nitrate test (plus anything of local concern), and a written report.⁴ To find one, use NGWA's contractor lookup on wellowner.org and its certified professionals directory. These are run by a trade association, not a state agency, so still check the state license.

Where a state publishes its home inspector license list, we load it on that state's page (currently North Carolina and New York). Other states we cover: Texas licenses inspectors through the Texas Real Estate Commission, but TREC's public data file doesn't include a location, so use TREC's license holder search. Wisconsin credentials home inspectors through DSPS, which sells its list rather than publishing it, so use DSPS's credential search. Pennsylvania and Michigan don't have a state license list for home inspectors that we could use.

Water treatment dealers

We list water treatment dealers (softener, filter and treatment system installers) only where a state publishes an official license list. A few states license this work. Where a state publishes its license list we load it (so far Texas: TCEQ Water Treatment Specialists), and where we've found a state license without a usable list, it's noted on that state's page, so check with your state too. To find someone with a voluntary credential, use these lookups. They are run by private trade associations, not by any government agency. A listing there is not a state license, and these groups mostly list their own members:

• Water Quality Association (WQA): Find a WQA-certified professional (people who hold WQA's voluntary certifications) and find WQA-certified treatment products (products WQA has tested and certified).
• National Ground Water Association (NGWA): Find a water well contractor on NGWA's wellowner.org (NGWA members; NGWA says it "neither endorses nor guarantees the work of any company listed")⁵ and the directory of NGWA-certified professionals.

Before you buy treatment, get your water tested by a state-certified lab (each state page lists or links them) and run the results through the free Well Test Results Checker, so you only treat for what's actually in your water.

Questions to ask before hiring a well contractor

Get information on several contractors before you choose.⁶ These questions come from the National Ground Water Association's well owner guidance and New York DEC's consumer checklist:⁶⁷

• Are you licensed, registered or certified by the state for this work? Not every state requires it. Check the answer yourself with the state lookup on this page.
• Is the person supervising the job certified? NGWA offers voluntary certification; its highest level is Master Groundwater Contractor (MGWC).⁶
• Do you file a well log or completion report, and will I get a copy? Some states require the driller to give the owner a copy (New York does, for example).⁷ Keep it with your deed.⁶
• What liability and workers' compensation insurance do you carry?⁶
• Can I talk to recent customers? Ask for references and call them.⁷
• Will you give me a written contract?⁶ In New York, for example, home improvement work over $500 needs a written contract by law.⁷
• Do I need a local permit? Check with your local health and building code officials. Some counties set their own rules.⁷

What to check on a quote

Get more than one estimate.⁷ NGWA says an itemized list of charges is better than a lump sum, because you can't compare offers unless you know what each one covers.⁶ For a drilled well, look for:⁶

• Price per foot of drilling and per foot of casing, plus the casing diameter and thickness
• Other materials (drive shoe, grout, well cap) and other steps (grouting, development, test pumping, disinfection)
• The type of well cap or seal, and the disinfection procedure
• What happens, and what it costs, if they must drill deeper or drill a second well, or abandon and seal a dry or bad hole
• Cleanup of the site, an expected start date, and a guarantee of materials and workmanship
• A statement that the work will meet state and local codes
• What is not included

When the well is finished, NGWA suggests checking the depth against the construction report, asking what yield (gallons per minute) the well was tested at, making sure the cap is secure and at least 6 inches above ground, asking whether the well was disinfected, and getting your copy of the well record.⁶

Buying treatment? Test first. A lab report from a state-certified lab tells you what you're actually treating for. Pennsylvania DEP, for example, says to pick a treatment device for the specific contaminant your test found, and points to NSF's product database.⁸ Put your numbers into our free Well Test Results Checker to see how they compare with EPA benchmarks.
