Water & Wastewater Operator Certification in Virginia
What it takes to get and keep a water or wastewater operator license in Virginia, and where to go for help. This page is the map: who runs the program, what the grades are, what the exam costs, and how renewal works. It is not exam prep. Rules change, so confirm with the agency before you act.

This page won't tell you how to pass a test. It tells you what's required in Virginia and how the process actually works, so the paperwork doesn't stand between you and the job.
Your path to certified in Virginia
- The license comes from a licensing board, not the water agency. Virginia operators are licensed by the Board for Waterworks and Wastewater Works Operators, housed in the Department of Professional and Occupational Regulation. The Health Department holds drinking-water primacy and classifies plants, but it does not license operators.
- Two separate licenses, not one. One board and one regulation issue a Waterworks Operator license (Classes 1 to 6) and a separate Wastewater Works Operator license (Classes 1 to 4). Work both sides and you hold both.
- The numbers run backward. Class 1 is the highest, most advanced license; the biggest number is the entry level. A license covers its class and all the lower (higher-numbered) ones.
- Start provisional. The entry credential is a Provisional license, which on its own cannot run a classified facility; you convert it to a standard license after showing half the experience your target class requires.
- Test through PSI, then renew on an offset clock. Apply to the board, then schedule the PSI exam; results are pass or fail with no number given. Waterworks licenses renew in odd years, wastewater in even years, both at the end of February.
The exam follows the national ABC criteria. Drill it free in the practice tool before you schedule with PSI.

Who runs certification here
Virginia hands the three pieces of an operator's working life to three different agencies, and the split is the load-bearing fact. The license comes from the Board for Waterworks and Wastewater Works Operators, inside the Department of Professional and Occupational Regulation, a professional-licensing department, under one regulation (18VAC160-30). Virginia's Department of Health, through its Office of Drinking Water, holds Safe Drinking Water Act primacy and sets the classifications for the drinking-water plants, while the Department of Environmental Quality classifies and permits the wastewater plants. The health and environmental agencies set what class of operator a facility needs, but neither licenses the person. So an operator applies to the licensing board, sits an exam, and works in a facility two other agencies regulate.
The grades and what they cover
It is not a unified license. One board issues two separate credentials: a Waterworks Operator license with six classes and a Wastewater Works Operator license with four. The numbering is the thing to get straight, because it inverts the usual order: Class 1 is the highest and most advanced, and the largest number is the entry rung (Class 6 on the water side, Class 4 on wastewater). A license lets you run its class and every lower one above it in number. A small wrinkle to expect: the wastewater operator classes are written in Arabic numerals while the underlying facility classes the environmental agency assigns are Roman, so a Class 2 license runs a Class II plant. The entry credential is a Provisional license, which on its own cannot serve a classified facility; you move up to a standard license by documenting half the experience the target class calls for.
The exam: logistics, not cramming
You apply to the board first, and once it approves you, you schedule the computer-based exam with PSI, which delivers it against the national ABC need-to-know criteria year-round at sites across the state. The fee is tiered by class rather than by side: about $83 for the two entry classes and $124 for the advanced ones. Two things surprise people. First, the result is pass or fail with no numeric score, because the cut score is set by the testing organization, not published in regulation. Second, the clock: a passing score is good for ten years, but you have to pass within twenty-four months of the board approving your application or reapply under whatever rules are in effect then.
For what the exams cover by grade, the what's on the exam guide is the place to start.
Keeping it current (renewal)
Both licenses run two years, but they expire in different years, which trips up dual-licensed operators. Waterworks licenses expire the last day of February in odd-numbered years; wastewater licenses, the last day of February in even-numbered years. Renewal is $80 per license, with a thirty-day grace before a reinstatement fee applies. Continuing professional education scales with class: the top two classes take 18 hours including at least 4 in utility management, the middle classes 16 to 18, and the small water-only classes as few as 4. A license held less than two years at its first expiration is exempt from the hours, and excess hours do not carry to a future cycle.
Training and continuing education
Virginia Rural Water Association is the small-system anchor, running operator training and exam guidance, water and wastewater circuit-rider technical help, source-water protection, and staff-development programs from Buena Vista. The Virginia Section of AWWA and the Virginia Water Environment Association cover the broader conference circuit and together support the state's mutual-aid network. The continuing-education hours must carry board approval and match the license you renew.
Reciprocity
Virginia is strict here: there is no true reciprocity. An operator licensed in another state can use that out-of-state credential to satisfy Virginia's experience and education requirements, but it never waives the exam. Whatever you hold elsewhere, you sit and pass the Virginia board exam to be licensed in Virginia.
Where to get help (small systems)
- Virginia Rural Water Association, vrwa.org: operator training, exam guidance, circuit-rider technical assistance, and source-water protection, from Buena Vista.
- Apply to the licensing board, not a health or environmental agency: DPOR's operator board issues the license; the Health and Environmental Quality departments classify the facilities.
- The board's regulation (18VAC160-30) carries the class ladders, the experience and education table, fees, and renewal.
- VA AWWA and VWEA run the schools and conferences that supply continuing-education hours.
Running a system in Virginia
The oversight and funding picture for managers and boards.
Rate regulation. The Virginia State Corporation Commission regulates the rates and service of investor-owned water and sewer companies only. Municipal and authority-owned systems set their own rates and are outside the commission, deciding through the local governing body or authority board.
Funding. The two revolving funds share one financial manager but split their policy homes: the Health Department runs the drinking water fund and the Department of Environmental Quality runs the clean water fund, while the Virginia Resources Authority underwrites and closes the loans for both.
Mutual aid. Virginia participates in the national WARN framework for utilities helping utilities after an emergency, supported by the state AWWA and water environment associations. Sign the agreement before the hurricane.

- The split is the load-bearing fact: DPOR's operator board issues the license (under 18VAC160-30), the Health Department holds drinking-water primacy and classifies water plants, and the Department of Environmental Quality classifies wastewater plants.

- It is two separate licenses (waterworks Class 1 to 6, wastewater Class 1 to 4) with inverted numbering (Class 1 highest), offset renewal years, and no reciprocity without the Virginia exam. The PSI exam reports only pass or fail, so this page states no passing percentage.
