Water & Wastewater Operator Certification in Tennessee

Your path to certified in Tennessee

1. One board, one training center. Tennessee certifies water and wastewater operators through a single Water and Wastewater Operators Board of Certification, in TDEC's Division of Water Resources, with the Fleming Training Center in Murfreesboro running the training, exams, and recordkeeping.
2. Fourteen certificate types. Water treatment runs a Small Water System class plus Grades I to IV; water distribution and wastewater collection each stop at Grade II; wastewater treatment runs a Biological and Natural System class plus Grades I to IV. The plant's grade sets the grade you need.
3. No trainee license. There is no operator-in-training tier; you enter at the lowest class for your discipline, which still takes a diploma, the minimum experience, and a passed exam.
4. The state runs the exam. The board gives its own exams through the training center, not a commercial vendor, and you pass at 70 percent. Apply at least sixty days ahead, and note the long retake rule: a failed exam locks you out of that classification for five months.
5. Two clocks at renewal. The certificate renews every year (cheaper before February), but continuing education runs on a separate three-year cycle.

The exams are state-run, but the math is the same math. Drill it free in the practice tool before you apply.

Who runs certification here

Tennessee runs one of the cleanest single-program structures in the region. A single Water and Wastewater Operators Board of Certification, inside TDEC's Division of Water Resources, certifies operators across all four disciplines, drinking water treatment and distribution and wastewater treatment and collection, under one rule and one statute. The day-to-day work, training, exams, and certification records, runs through the Fleming Training Center in Murfreesboro, which operators also use to track their continuing education online. The same division holds Safe Drinking Water Act primacy and the wastewater discharge program. There is no separate wastewater board here, unlike some neighboring states.

The grades and what they cover

Tennessee issues fourteen certificate types across the four disciplines. Water treatment runs a Small Water System class below Grades I through IV; wastewater treatment runs a Biological and Natural System class below Grades I through IV. Water distribution and wastewater collection are shorter ladders, Grades I and II only, with no third or fourth grade. A facility is graded on a points system for plants and by population or flow for distribution and collection, and the operator in direct charge has to hold a certificate at or above the facility's grade. There is no operator-in-training license: the entry rungs are the Small Water System, Biological and Natural System, and Grade I classes themselves, each of which still takes a diploma, a year or so of matching experience, and a passed exam.

The exam: logistics, not cramming

The board gives its own exams through the Fleming Training Center, not through a commercial testing vendor, in written or electronic form and closed book. The pass mark is a uniform 70 percent across every grade. You apply at least sixty days before the exam date with a $100 fee, and once approved you have twelve months to sit. Two rules are stricter than most states: a failed exam locks you out of that classification for five months, and failing the same exam twice triggers a required block of board-approved training, thirty hours for the upper grades, before a third attempt.

For what the exams cover by grade, the what's on the exam guide is the place to start.

Keeping it current (renewal)

Tennessee runs two clocks, and they are easy to confuse. The certificate renews every year: it expires December 31, the paperwork is due by June 30, and the fee is $50 if you pay before February and $100 after, charged per certificate. Continuing education runs on a separate three-year cycle, with the hours scaling by grade (the lower grades owe fewer hours than the upper ones). The hard part is the lapse rule: miss the June 30 renewal, and past a short variance window you re-qualify as a brand-new applicant for that class, exam included, so there is no soft grace period to lean on.

Training and continuing education

Tennessee Association of Utility Districts is the small-system anchor, and it fills the role a rural water association plays elsewhere, since Tennessee has no separately named one. From Murfreesboro it runs operator and certification-prep training, backflow and safety courses, utility-commissioner training, and on-site technical help, and it coordinates the state's mutual-aid network. The Kentucky/Tennessee Section of AWWA covers the drinking-water conference circuit. The training center approves the courses that count, and the hours feed the three-year continuing-education total.

Reciprocity

Tennessee offers reciprocity by application to the board, with a $100 fee. Rather than transfer your license outright, the board weighs your out-of-state education and experience against Tennessee's own ladder, grade by grade, and it has to receive verification straight from the state that issued your certificate before it acts. A complete reciprocity application is due at least sixty days before the board meeting that will consider it.

Where to get help (small systems)

• Tennessee Association of Utility Districts, taud.org: operator and certification-prep training, technical assistance, and utility-commissioner courses, from Murfreesboro. It is the state's rural-water equivalent.
• The Fleming Training Center delivers the training and exams and hosts the online portal where operators track certification and continuing education.
• The Small Water System and Biological and Natural System classes are the entry points for the smallest plants.
• The Kentucky/Tennessee Section of AWWA covers the two-state conference circuit.

Running a system in Tennessee

The oversight and funding picture for managers and boards.

Rate regulation. The Tennessee Public Utility Commission regulates the rates and service of investor-owned water and wastewater utilities only. Municipal utilities and the independent utility districts that serve much of the state set their own rates and are outside the commission, with district rates set by their own boards of commissioners.

Funding. Both revolving funds are run by TDEC's Division of Water Resources together with the Tennessee Local Development Authority: the division handles eligibility and the priority list while the authority, a financing board under the state comptroller, issues the bonds and approves the loans.

Mutual aid. Tennessee participates in the national WARN framework for utilities helping utilities after an emergency, coordinated with the utility districts association. Sign the agreement before the ice storm.
