Well Driller List

State rules

Tennessee

Tennessee licenses individuals, not companies, to drill wells and to install pumps and treatment equipment. The Department of Environment and Conservation, Division of Water Resources, says any person who conducts, manages, or supervises digging, drilling, redrilling, or maintenance of a well, or who installs or repairs well pumps, filters, treatment devices, or geothermal closed loops, must obtain a license from the division. A Tennessee general contractor, electrician, or plumber may not do that work unless also licensed by the division. Licenses expire on July 31 and are not transferable. New applicants need at least two years of experience, shown by a list of ten wells spanning two years or by occupational licenses covering two years. The page states application fees of $100 for driller licenses and $50 for pump installer and water treatment installer licenses.

Checked against official sources on October 11, 2026. Rules and links change; confirm with the office listed before you act.

Applications go to Water.Well@tn.gov. The applicant must score at least 70 percent on the general exam and on each specialty portion. A passing applicant is interviewed by the Board of Groundwater Management, which recommends licensing to the commissioner. The division may revoke, suspend, or deny a license for violations, and civil penalties are possible. Renewal is due by July 31. For the cycle described on the page, the division said it would send reminders around May 15, 2026, and would not accept renewals sent before that date. Five hours of continuing education obtained on or after August 1, 2025, are required, except for first-year license holders.

Renewal includes an affidavit of supervision when it applies. The page says operator certificates expire if a new affidavit is not submitted. Payment is invoiced by the Division of Fiscal Services and is not mailed with the application to that division. The department's published address is Davy Crockett Tower, 500 James Robertson Parkway, Nashville, TN 37243, and the general phone is (888) 891-8332. A mailing instruction line on the page says to call 615-532-0192 for mail instructions. Those numbers are printed on the license page. The fee figures are also printed there and are not stored in the fee field of this record.

The page links the well licensing regulations, the Board of Groundwater Management rules, the well statutes, and a list of licensed drillers and installers. This record does not copy that list. A customer should ask which license the individual holds, driller or installer, and should ask for the driller report and, if a well is closed, the closure report the division publishes. Geothermal closed-loop work is included in the license requirement on the page. A plumbing license alone does not meet the division's statement.
