TL;DR
Tennessee well drillers get licensed by the Tennessee Well Driller's Licensing Board, which sits under TDEC. You need that license before you drill any water well. The application requires a written exam, documented field experience, and fees set by board rule. Fees and processing times shift with rule amendments, so confirm current figures with the board before you send a check.
Do you need a license to drill wells in Tennessee?
Yes. No person may drill, deepen, alter, or abandon a water well in Tennessee without a valid license from the Tennessee Well Driller's Licensing Board. That requirement comes straight from Tennessee Code Annotated Section 69-10-104, which makes it unlawful to engage in the business of well drilling without first getting a license. [1]
The law covers water wells used for drinking, irrigation, geothermal, and monitoring. Exemptions are narrow. A landowner can drill on their own land for personal use in limited cases, but anyone doing it commercially, or for hire, needs the license. Building a drilling business here means going through the board. There is no side door.
The board sits inside the Tennessee Department of Environment and Conservation (TDEC). TDEC's Division of Water Resources handles the technical side, including well construction permits, while the licensing board decides who is qualified to do the work. The two functions connect: you need a license to get a permit, and you need a permit before you drill. [2]
Who runs well driller licensing in Tennessee?
The Tennessee Well Driller's Licensing Board is the official body. It is a statutory board created under TCA Title 69, Chapter 10, with members appointed by the governor. The board meets periodically to review applications, set policy, and handle discipline. [5]
Day-to-day work runs through TDEC's Division of Water Resources. That office processes applications, schedules exams, and keeps the public license lookup. TDEC is the practical first stop for anyone starting the process. [2]
The board sets fees by rule. That means fee amounts can change without a full legislative session, so a number that was right last year can be stale today. Confirm the current fee schedule with TDEC or the board office before sending a check. Figures posted on third-party sites, including summaries like this one, can lag rule amendments by months.
What are the license types available in Tennessee?
Tennessee issues several categories of well driller license, broadly covering water well driller, limited water well driller, and pump installer. The distinctions matter. Each carries a different scope of work and a different experience threshold. [5]
A full water well driller license lets you drill any permitted well. A limited license usually restricts depth or well type. A pump installer license covers setting and servicing pumps but does not authorize drilling. If your work spans both drilling and pump installation, you hold both licenses or you work under someone who does.
| License Type | Primary Work Authorized | Exam Required |
|---|---|---|
| Water Well Driller | Drilling, deepening, altering, abandoning water wells | Yes |
| Limited Well Driller | Restricted scope (confirm current limits with board) | Yes |
| Pump Installer | Pump setting and servicing | Yes |
Tennessee also requires a separate well construction permit for each well site, independent of your driller license. The license proves you are qualified. The permit covers the specific job. [1]
How much does a well driller license cost in Tennessee?
Fee amounts are set by board rule and can change. Based on Tennessee rule filings, application and examination fees for well driller licenses have historically fallen in the $50 to $200 range per category, with renewal fees usually lower than initial application fees. [3] Confirm the current schedule with TDEC's Division of Water Resources before you submit anything, because rule amendments do not always come with wide public notice.
The license fee is only part of the bill. Budget for the exam (if a third-party testing vendor administers it, expect a separate proctoring fee), any required insurance or bond, and the per-well construction permits you pull once licensed. Construction permit fees are separate from the driller license fee and depend on well type and depth.
Coming from a neighboring state? Tennessee has reciprocity provisions. Drillers licensed in states with comparable standards may qualify without re-taking the full exam. Reciprocity is not automatic, though. You still file an application and the board reviews your home-state credentials. See how the well driller board in Alabama and the well driller board in Georgia handle their fee structures if you're comparing across the region.
What experience do you need to qualify for the Tennessee exam?
Tennessee wants documented field experience before you sit for the well driller exam. The standard threshold has been two years working under a licensed well driller, though you should verify the current number in the board's rules because the exact hour or year count can shift with amendments. [3]
Experience has to be verifiable. Your supervising driller signs off, or you produce employment records, payroll documentation, or affidavits the board finds credible. Vague claims of general construction experience don't cut it. Drilling-specific field time is what counts.
Coming in from plumbing, excavation, or general contracting? Don't assume crossover experience transfers on its own. Call the board office before you spend money on exam prep. They can tell you which parts of your background count and which gaps you still have to fill.
What does the Tennessee well driller exam cover?
The exam tests several domains: Tennessee well construction rules, basic hydrogeology, drilling methods, casing and grouting requirements, well development, and pump basics. The grouting section carries real weight because Tennessee, like most states with karst geology, holds strict grouting standards to keep surface contamination out of aquifers. [4]
Tennessee's well construction rules under TDEC Chapter 0400-45-09 spell out minimum casing depths, grout requirements by formation type, and setback distances from contamination sources. The exam pulls directly from those rules, so the rule text is effectively your study guide. Read the actual rule language, not a summary. [4]
Exam scheduling, location, and passing score are set by the board. Some states route testing through vendors like Prometric or PSI, which adds a separate scheduling fee. Confirm the current exam format with TDEC before you book anything.
How long does the Tennessee well driller license take to get?
There's no honest single number. The timeline stacks in pieces: gathering your experience documentation, getting the application accepted as complete, waiting for an exam date, passing, then waiting for the board to process and issue the license.
Application review alone can run several weeks if the board has a backlog or your file comes back for corrections. Exam scheduling depends on how often the state offers test dates. After you pass, issuance usually takes a few weeks more.
A realistic minimum, for someone who starts with every document ready, is probably 60 to 90 days from first submission to license in hand. It runs longer often enough. Nobody has published a formal average processing time for Tennessee well driller licenses; the closest guidance is TDEC's own application instructions, which tell you to allow adequate time before your planned start date. Plan conservatively and confirm current expectations with the board office. [2]
What paperwork does the Tennessee well driller application require?
The application package usually includes a completed application form, experience verification (signed by your supervising driller or backed by employment records), proof of insurance if current rule requires it, examination scores or exam registration, and the applicable fee. [3]
For each well you drill after licensing, you also need a separate well construction permit from TDEC. The permit application asks for your license number, the property owner's information, the proposed well location, and the intended use. Tennessee's well construction permit form is a different document from the license application.
Clean grout logs and completion reports are required, more than good practice. Tennessee Rule Chapter 0400-45-09 requires drillers to submit a well completion report (sometimes called a water well record) to TDEC within 60 days of finishing a well. [4] That report documents casing details, grouting, formation logs, and yield testing. Miss the deadline and you have a compliance violation that can hit your license standing.

How does Tennessee well driller license renewal work?
Tennessee well driller licenses are not permanent. They require periodic renewal, historically on a two-year cycle, though you should confirm the current period with the board. [3] Renewal takes a fee and may require documentation of continuing education, depending on current rules.
Continuing education, where required, focuses on updates to well construction rules, grouting standards, and environmental compliance. Tennessee has revised its well construction rules over time, and the board expects licensed drillers to stay current. Let your continuing education lapse and then renew late, and you open compliance gaps that complicate your permit applications.
Renewal notices go to the address on file with the board. Move or change your business address, and you update your record with TDEC promptly. A missed notice because of a stale address is your problem, not the board's.
What are Tennessee's well construction and grouting rules?
Tennessee's well construction rules live in TDEC Rule Chapter 0400-45-09. That chapter sets the technical standards every licensed driller follows: minimum casing depths by formation type, grout material specifications, grout placement methods, setback distances from septic systems and other contamination sources, and well development and testing requirements. [4]
Grouting runs strict in Tennessee because of the state's karst terrain in the eastern and central regions. Karst limestone has voids and conduits that can channel surface contamination straight to aquifer zones. [6] Tennessee requires grout from the surface down to a specified minimum depth, and that grout has to meet permeability standards designed to seal those pathways.
The rule also governs abandonment. A well that's no longer in use cannot sit open. Licensed drillers must properly abandon unused wells by filling and sealing them to TDEC specifications. The abandonment work itself requires a permit, and only a licensed driller can do it legally.
Neighboring states handle some of this differently. See the well driller board in Arkansas for how a nearby state structures its grouting and construction rules.
Does Tennessee have reciprocity with other states?
Tennessee's licensing law includes a reciprocity provision. A driller licensed in another state may apply for a Tennessee license without taking the full exam, if Tennessee finds the other state's standards substantially equivalent to its own. [5]
Reciprocity is not a rubber stamp. You still submit a complete application, pay the fee, and let the board review your home-state license, the standards behind it, and your work history. If there are gaps (your home state doesn't require a grouting exam, say), the board may make you pass a partial exam covering those topics.
States bordering Tennessee that run their own well driller licensing include Alabama, Georgia, and Arkansas. Already licensed in one of those and planning to work here? Call the board office before assuming reciprocity applies. See the well driller board in Alabama and the well driller board in Georgia for how those states structure their programs, useful background for a reciprocity conversation with Tennessee.
What happens if you drill without a license in Tennessee?
The penalties are real. TCA Section 69-10-104 makes unlicensed well drilling a Class A misdemeanor for the first offense. Repeat violations step up in severity. Beyond criminal exposure, TDEC can issue civil penalties and stop-work orders, and any wells drilled without a license can face required remediation at the driller's expense. [1]
For a business, the risk goes further. If a customer's well is later found to have construction defects and the driller wasn't licensed, insurance coverage may not apply. That leaves the driller personally exposed on property damage and contamination claims.
The board also disciplines licensed drillers for construction rule violations, false reporting on completion records, and other conduct issues. Discipline ranges from a formal reprimand to suspension or revocation. The public license lookup on TDEC's site shows current license status and disciplinary history, and customers increasingly check it. [2]
Where do you contact the Tennessee Well Driller's Licensing Board?
TDEC's Division of Water Resources is the operational contact point. Its well resources program handles applications, permits, and licensing questions. You can reach the division through TDEC's main contact channels on the official site. [2]
For the board itself, meeting schedules, rule filings, and official decisions come through the Tennessee Secretary of State's administrative rules system and TDEC's own communications. When you call or email, ask specifically for the well driller licensing section so you don't get routed to the broader water resources program.
To get your paperwork in order before that call, WellDrillerPath's reference kit at /start puts the document checklist in one place, which makes the first conversation more productive. The board office is still the only authoritative source on current fees, deadlines, and exam dates.

Frequently asked questions
Do you need a license for well drilling in Tennessee?
Yes. Tennessee Code Annotated Section 69-10-104 requires anyone engaged in the business of well drilling to hold a valid license from the Tennessee Well Driller's Licensing Board. This applies to commercial drillers, contractors, and anyone drilling for hire. Unlicensed drilling is a criminal offense and can bring civil penalties and mandatory well remediation.
How much does a well driller license cost in Tennessee?
License fees are set by board rule and can change. Historical application and examination fees have run roughly $50 to $200 per license category, with renewal fees usually lower. Exam proctoring, insurance, and per-well construction permits add to the total. Confirm the current fee schedule with TDEC's Division of Water Resources before submitting your application.
How long does it take to get a well driller license in Tennessee?
A realistic estimate is 60 to 90 days from a complete application to license issuance, but it can run longer depending on board backlog, exam scheduling, and whether your file needs corrections. No official average processing time has been published. Confirm current timelines with the board before you plan a start date.
What experience do I need before applying for the Tennessee well driller exam?
Tennessee wants documented field experience working under a licensed well driller, historically at least two years. Experience has to be verifiable through employer records or supervisor affidavits. General construction or excavation experience usually does not substitute. Confirm the current requirement with the board before applying, since rule amendments can adjust the threshold.
Does Tennessee offer well driller license reciprocity with other states?
Yes. Tennessee's licensing law includes a reciprocity provision for drillers licensed in states with substantially equivalent standards. Reciprocity is not automatic: you still file an application and the board reviews your home-state credentials. Gaps in your home state's requirements, such as no grouting exam, may require a partial Tennessee exam. Call the board before assuming it applies.
What is the Tennessee Well Driller's Licensing Board and who runs it?
The Tennessee Well Driller's Licensing Board is a statutory board created under TCA Title 69, Chapter 10, with members appointed by the governor. Day-to-day administration runs through TDEC's Division of Water Resources. The board sets licensing policy, reviews applications, and handles discipline. TDEC processes applications and permits operationally.
What are the grouting requirements for well drillers in Tennessee?
Tennessee Rule Chapter 0400-45-09 requires grout from the surface down to a minimum depth, with specific material and placement standards. Requirements run strict in karst terrain, common in eastern and central Tennessee, because limestone voids can channel surface contamination to aquifers. Grout must meet permeability standards set in the rule. The exam tests grouting knowledge directly.
What is the well completion report requirement in Tennessee?
Licensed drillers must submit a well completion report to TDEC within 60 days of finishing a well, per Rule Chapter 0400-45-09. The report documents casing, grout, formation logs, and yield data. Missing the deadline is a compliance violation and can affect your license standing. Every well drilled requires its own report, regardless of type or size.
Can a landowner drill their own well in Tennessee without a license?
Tennessee law has narrow exemptions for landowners drilling on their own property for personal use, but anyone doing it commercially or for hire needs a license. The exemption is limited and does not cover typical business activity. If there's any question about whether your situation qualifies, contact TDEC before drilling. The penalties for unlicensed drilling are criminal.
How often do Tennessee well driller licenses need to be renewed?
Tennessee well driller licenses have historically required renewal on a two-year cycle. Renewal takes a fee and may require documentation of continuing education, depending on current board rules. Confirm the current renewal period and any CE requirements with TDEC. Keep your address current with the board so renewal notices reach you on time.
What are the penalties for drilling a well without a license in Tennessee?
Unlicensed well drilling is a Class A misdemeanor under TCA Section 69-10-104 for a first offense, with escalating penalties for repeat violations. TDEC can also issue civil penalties, stop-work orders, and require remediation of improperly drilled wells at the driller's expense. Insurance coverage may not apply to work done without a license.
Where can I look up whether a Tennessee well driller is licensed?
TDEC's Division of Water Resources maintains a public license lookup for well drillers in Tennessee. Current license status and disciplinary history are available through that system. Customers and property owners increasingly use the lookup before hiring a driller, so keeping your license current and your record clean matters for business reasons beyond legal compliance.
