TL;DR
Tennessee licensed well drillers renew with TDEC's Water Well Program every calendar year, and the license expires December 31. Renewal takes a fee (confirm the current amount with the board), proof of any required continuing education, and a completed renewal form. Let it lapse and you face a late penalty or a full reapplication, exam included. Renew before December 31.
Do you need a license to drill wells in Tennessee?
Yes. Anyone who drills, constructs, or alters a water well in Tennessee has to hold a valid water well contractor license from the state. This is not optional and it is not a local-only rule. The requirement comes straight from Tennessee Code Annotated Section 69-10-108, which says "no person shall engage in the business of water well contracting without first obtaining a license from the department." [1]
The Tennessee Department of Environment and Conservation (TDEC) runs the Water Well Program. It handles initial licensing, annual renewals, and the technical standards wells have to meet. Drill without a license and you're exposed to civil penalties, and any contract tied to unlicensed work can fall apart.
If you supervise other drillers on a site, your license number goes on the permit and the well completion report. There's no apprentice carve-out that lets someone drill without a licensed contractor of record on the project.
How much does a well driller license cost in Tennessee?
The Water Well Program charges an application fee for new licenses and an annual renewal fee. Fee schedules change, so confirm the current amount with TDEC before you write a check. Tennessee Code Annotated Section 69-10-108 authorizes the department to set fees by rule, and contractor renewals have historically run in the $100 to $200 range per year. Pull the current fee schedule from the TDEC Water Well Program page before submitting payment. [1][2]
There's also a well permit fee paid per well drilled, separate from your license renewal. You pay that when you pull the permit, not at renewal.
Late renewal usually adds a penalty on top of the standard fee. The program can accept a late renewal or make you reapply from scratch, so missing the December 31 deadline is a genuine risk to your operating status.
The table shows the general fee structure authorized by statute. Confirm exact dollar amounts with TDEC before submitting.
| Fee Type | When Due | Ballpark Range (confirm with TDEC) |
|---|---|---|
| Initial application | First-time license | $100-$200 |
| Annual renewal | By Dec 31 each year | $100-$200 |
| Late renewal penalty | After deadline | Additional charge |
| Per-well permit | Each well drilled | Separate fee schedule |
How long does the renewal process take in Tennessee?
Most clean renewals process within a few weeks when you submit well before the December 31 deadline. TDEC doesn't publish a guaranteed processing time, so "a few weeks" is a working assumption based on how state licensing programs of similar size operate. Nobody has precise public data on TDEC's current queue. The honest answer: submit early, confirm receipt, and follow up if you haven't heard back within 30 days.
Renewals filed close to the deadline or during high-volume periods can take longer. If yours is still in processing when December 31 passes, call the program about your status rather than assuming you're covered.
First-time licensing takes longer than renewal because it includes a state-administered exam. Renewal skips the exam, so it moves fast.
What is the renewal deadline for Tennessee well driller licenses?
Tennessee water well contractor licenses expire December 31 each year. It's a hard calendar-year cycle, not a rolling anniversary tied to when you first got licensed. [1]
That structure catches new drillers off guard. Get licensed in October and you have less than three months before your first renewal is due. Plan for it.
The program mails renewal notices, but leaning on the mail is a bad habit. Put December 31 in your calendar with a 60-day lead reminder. If your address changed and you didn't update it with TDEC, you might never get the notice, and that won't excuse a late renewal.
What continuing education is required for renewal in Tennessee?
Tennessee's water well regulations have included continuing education tied to renewal. The specific hour count and approved course list live in TDEC rule, not the statute, so the department can update them without legislative action. Confirm the current CE hour requirement and approved providers directly with the TDEC Water Well Program before you renew. [2]
Approved training often runs through the National Ground Water Association (NGWA) or Tennessee well driller association programs. NGWA courses get accepted in many states, and Tennessee has historically recognized NGWA credits. [3]
Keep your CE certificates. TDEC can audit renewals and ask you to produce proof. Losing those records mid-audit is a headache you don't need.

What forms do you need to renew a Tennessee well driller license?
The core document is the TDEC renewal application form, available on the Water Well Program section of the TDEC website. You'll fill in your current license number, contact information, well contractor business details, and CE completion information.
You'll also need to attach or confirm:
- Proof of continuing education (certificates from approved providers)
- Payment for the renewal fee (check, money order, or electronic payment depending on what TDEC currently accepts)
- Any updated business or address information
Some drillers also confirm active general liability insurance at renewal. Check the current renewal checklist on TDEC's site because requirements shift between rule cycles.
Never mail anything without keeping a copy. If TDEC has questions, you need to know exactly what you sent them.
What happens if your Tennessee well driller license lapses?
An expired license means you can't legally drill in Tennessee. Full stop. Any well permitted under an expired license number creates liability for you and the property owner both.
A short lapse may get you a late renewal with a penalty fee. A long lapse can force you to reapply as a new applicant, which means the full application process and potentially retaking the exam. The program has discretion here, so call them the moment you realize there's a problem. Don't wait.
Some neighboring states handle lapses differently. Well driller renewal in Arkansas and well driller renewal in Florida each set their own late-renewal windows and reinstatement rules worth knowing if you work near those borders.
How does Tennessee's licensing structure compare to nearby states?
Tennessee runs a state-level licensing system through TDEC, with annual renewal on a calendar-year cycle. That's a reasonable middle ground. Here's how a few neighbors stack up:
| State | Renewal Cycle | Administrator | CE Required |
|---|---|---|---|
| Tennessee | Annual (Dec 31) | TDEC | Yes (confirm hours) |
| Alabama | Annual | ADEM | Yes |
| Georgia | Annual | EPD | Yes |
| Arkansas | Annual | ADEQ | Yes |
| Florida | Biennial | FDEP | Yes |
Florida's biennial cycle means a bigger check every two years but paperwork half as often. Tennessee's annual cycle keeps each payment smaller and demands attention more often. Neither is objectively better. It depends on your cash flow and how good your administrative calendar is.

Where do you submit your Tennessee well driller renewal?
Renewals go to the Tennessee Department of Environment and Conservation, specifically the Water Well Program. TDEC's mailing address and any online submission portal are listed on the Water Well Program page of the TDEC website. [2]
As of this writing, Tennessee accepts paper renewals by mail. Some states have moved to online portals, so confirm whether TDEC offers that option when you're ready to submit. The process can change between rule cycles.
Mailing? Use certified mail with return receipt. That creates a paper trail showing TDEC got your renewal before the deadline. It costs about $5 and it has saved drillers from late penalties when renewals got lost in internal mail routing.
What are the insurance and bonding requirements for renewal in Tennessee?
Tennessee water well contractors generally have to carry general liability insurance. The statute lets the department set minimum coverage amounts by rule. Confirm the current minimum limits with TDEC at renewal time, because coverage requirements can change through rulemaking without a full legislative overhaul. [1][4]
Some contractors also carry pollution liability or completed-operations coverage, especially if they do remediation or pump work alongside new well construction. State rules don't always require it, but clients and their insurers ask for it more and more.
Bonding requirements, if any, get set separately and should also be confirmed directly with the program. Don't assume last year's certificate is still enough. Pull the current requirement before renewal.
How do the Tennessee well driller rules protect groundwater quality?
The licensing requirement exists because a badly built well can contaminate an aquifer. Tennessee Code Annotated Chapter 69-10 sets up the Water Well Program specifically to protect the state's groundwater. [1] The construction standards TDEC administers cover casing depth, grouting, annular sealing, and completion reporting, all of which keep surface contaminants out of drinking water supplies.
Well completion reports are a key compliance document. After finishing a well, the licensed contractor files a completion report (sometimes called a well log or grout log) with TDEC. These reports feed the state's well database and become public record. If yours aren't filed on time or come in incomplete, that's a licensing problem independent of your renewal status.
Setting up paperwork systems for a new operation? WellDrillerPath sells a Well Board and Grout Log Kit at /start that covers the documentation side of compliance. It's a one-time purchase, not a subscription, and it's worth a look before your first job if you're newer to Tennessee's reporting requirements.
For how other states fold completion reporting into licensing, the well driller renewal in Idaho and well driller renewal in Colorado pages cover similar ground.
What's the fastest way to avoid problems at renewal time?
Build a renewal calendar right now. Set a reminder for October 1 each year to gather CE certificates, pull the current fee schedule from TDEC, and download the renewal form. That gives you 90 days of runway before December 31, more than enough for a clean renewal.
Call TDEC's Water Well Program if anything looks off. It's a small program and generally reachable. A 10-minute phone call to confirm your CE hours count beats filing an incomplete renewal and getting it kicked back in November.
Keep a folder, physical or digital, with your license certificate, CE records, insurance certificates, and the confirmation receipt from every renewal you've filed. Audits are rare. But when one hits, the driller who can't produce records is the one with a problem.

Frequently asked questions
Do you need a license for well drilling in Tennessee?
Yes. Tennessee Code Annotated Section 69-10-108 requires a state-issued water well contractor license for anyone who drills, constructs, or alters a well in Tennessee. There's no exemption for small jobs or private landowners hiring their own crew. TDEC's Water Well Program issues the license, and it renews annually by December 31.
How much does a well driller license cost in Tennessee?
TDEC charges an application fee for new licenses and an annual renewal fee. Historically these have run $100 to $200, but fees are set by rule and can change. Confirm the current amount with TDEC before paying. There are also separate per-well permit fees paid each time you pull a permit, which aren't part of the license renewal.
How long does the Tennessee well driller license renewal take to process?
TDEC doesn't publish a guaranteed turnaround. Most clean renewals filed well before December 31 process within a few weeks. Submit by early December at the latest. If you haven't received confirmation within 30 days, follow up with the program directly. Late submissions during high-volume periods can take longer.
When does a Tennessee well driller license expire?
Tennessee water well contractor licenses expire December 31 each calendar year. The cycle is the same for everyone regardless of when you first got licensed, so a driller licensed in October has less than three months before their first renewal is due. Mark your calendar and plan accordingly.
What continuing education do Tennessee well drillers need for renewal?
Tennessee requires continuing education for renewal, with hours and approved providers set by TDEC rule. The specifics can change between rule cycles, so confirm current requirements with TDEC before renewing. The National Ground Water Association is a commonly accepted provider. Keep your completion certificates, because TDEC can audit CE compliance.
What happens if I let my Tennessee well driller license expire?
You can't legally drill wells in Tennessee with an expired license. A short lapse may allow reinstatement with a late penalty fee. A longer lapse may force reapplication, potentially including retaking the exam. Call TDEC the moment you realize the license has lapsed. Don't keep drilling and hope no one notices; the liability exposure is real.
Does Tennessee require insurance to renew a well driller license?
Yes, Tennessee water well contractors generally must carry general liability insurance, with minimum coverage limits set by TDEC rule. Confirm current minimums before renewal because the rules can change. Some clients and projects also require pollution liability coverage beyond the state minimum. Have your current certificate of insurance ready when you submit.
Where do I send my Tennessee well driller renewal application?
Renewals go to the TDEC Water Well Program. The mailing address and any online submission options are listed on the Water Well Program page of the TDEC website. If mailing, send via certified mail with return receipt so you have proof of delivery before the December 31 deadline.
Can I renew my Tennessee well driller license online?
Confirm with TDEC whether an online portal is currently available. Tennessee has historically accepted paper renewals by mail, but the program's submission options can change. Check the current TDEC Water Well Program page before preparing your submission. If online renewal is available, it generally processes faster than mail.
Does Tennessee recognize well driller licenses from other states?
Tennessee has no broad reciprocity agreement automatically accepting out-of-state licenses. Drillers licensed elsewhere who want to work in Tennessee generally need a Tennessee license. Contact TDEC to ask whether any examination waiver or expedited process applies based on your experience or existing licenses. Requirements can change.
Are well completion reports required as part of Tennessee licensing compliance?
Yes. Tennessee-licensed contractors must file well completion reports with TDEC after finishing each well. These reports, sometimes called well logs or grout logs, document the well's construction details and feed the state's groundwater database. Failing to file timely, accurate completion reports is a compliance issue separate from your license renewal status.
Is there a Tennessee well driller exam for initial licensing?
Yes, initial applicants must pass a state exam covering well construction standards and regulations. Renewal doesn't require retaking the exam as long as the license stays current. If your license lapses long enough that TDEC makes you reapply as a new applicant, you may have to take the exam again.
How do Tennessee's well driller licensing fees compare to other states?
Tennessee's annual renewal fees, historically $100 to $200, are fairly typical for southeastern states. Some states charge less, some more. Florida renews on a biennial cycle, spreading a larger fee over two years. Neither Tennessee's fee level nor its annual cycle is an outlier regionally.
Who administers well driller licensing in Tennessee?
The Tennessee Department of Environment and Conservation (TDEC) runs the Water Well Program, which handles all water well contractor licensing: initial applications, annual renewals, permit issuance, and enforcement. The statutory authority is Tennessee Code Annotated Chapter 69-10.
