Florida water operator certification
Quick answer
How do I get certified as a water operator in Florida?
Florida licenses water and domestic wastewater treatment plant operators together under one Class A to D scale run by the FDEP Operator Certification Program, and licenses distribution system operators separately on a Level 1 to 3 scale. As of November 6, 2025, Florida newly allows reciprocity for out-of-state licensed operators, reversing a long-standing no-reciprocity policy.

Certifying agency: Florida Department of Environmental Protection (FDEP), Operator Certification Program
- Meet the education and documented operating-experience minimum for the license class you are applying for; hold a high school diploma or GED and score at least 70% on the class-specific exam.
- Submit your application and fee to the FDEP Operator Certification Program; the exam itself is delivered through PSI.
- New distribution-license applicants must now begin at Level 3, the top of the 3-level distribution scale, rather than starting at Level 1.
- Renew Class A, B, and C treatment licenses every 2 years and pay the $75 non-refundable renewal fee.
Water treatment
- D , Entry-level treatment license, $50 application fee
- C , $100 application fee
- B , $100 application fee
- A , Highest treatment classification, $100 application fee
- Exam
- State exam set by FDEP's Operator Certification Program, delivered through PSI; a high school diploma or GED is required and a passing score is at least 70%
- Application / certification fee
- $100 for Class A, B, or C; $50 for Class D
- Continuing education
- Continuing education required to renew, tracked by FDEP's Operator Certification Program
- Renewal cycle
- 2 years
- Reciprocity
- Yes, as of November 6, 2025. Florida newly allows licensure by reciprocity for out-of-state licensed treatment plant operators, reversing a prior policy under which Florida did not authorize reciprocity at all; applicants submit a copy of their active out-of-state license and the evaluation takes about 30 days.
Florida runs one combined Class A to D scale for both drinking water treatment and domestic wastewater treatment operators, rather than separate letter systems per discipline.
Water distribution
- Level 1
- Level 2
- Level 3 , Highest distribution classification; all new applicants must now begin licensure at Level 3
- Exam
- State exam set by FDEP's Operator Certification Program, delivered through PSI
- Reciprocity
- Yes, as of November 6, 2025, for out-of-state licensed distribution system operators, under the same new reciprocity rule that now covers treatment plant operators.
A 2025 licensing change requires all new water distribution license applicants to begin the process at Level 3 rather than entering at Level 1, collapsing what had been a 3-step entry ladder into a single starting point.
Wastewater treatment
- D , Entry-level treatment license, $50 application fee
- C , $100 application fee
- B , $100 application fee
- A , Highest treatment classification, $100 application fee
- Exam
- State exam set by FDEP's Operator Certification Program, delivered through PSI; a high school diploma or GED is required and a passing score is at least 70%
- Application / certification fee
- $100 for Class A, B, or C; $50 for Class D
- Renewal cycle
- 2 years
- Reciprocity
- Yes, as of November 6, 2025, reversing Florida's prior no-reciprocity policy for operators licensed in other states.
Domestic wastewater treatment plant operators share the same Class A to D scale, exam program, and fee structure as drinking water treatment operators in Florida.
Wastewater collection
Florida does not license this discipline as a distinct state credential.
Florida runs a more unified licensing structure than most of the rest of this batch: the FDEP Operator Certification Program licenses both drinking water treatment operators and domestic wastewater treatment operators on the same Class A through D scale, with the same exam program and the same fee schedule, rather than splitting water and wastewater into separately administered systems the way Connecticut or Delaware do.
One Class A to D scale for both treatment disciplines
A Class D license is the entry point, at a $50 application fee. Classes C, B, and A each carry a $100 application fee, with A the highest classification. Every applicant needs a high school diploma or GED and must score at least 70% on the class-specific PSI exam. Class A, B, and C licenses renew every 2 years and carry a $75 non-refundable renewal fee.
Distribution runs on a separate Level 1 to 3 scale, and the entry point just changed
Water distribution system operators are licensed separately, on a 3-level scale rather than the treatment side’s 4-letter scale. A 2025 rule change altered how new operators enter that scale: all individuals now wishing to obtain a water distribution license must begin the licensure process at Level 3, the top of the ladder, rather than starting at Level 1 and working up.
Florida just started allowing reciprocity
For years, Florida did not authorize reciprocity for water or wastewater operators licensed in other states or jurisdictions, an unusually strict stance among the states in this batch. That changed on November 6, 2025: Florida now issues a license by reciprocity to an applicant who has performed duties comparable to a Florida-licensed water treatment plant operator, wastewater treatment plant operator, or distribution system operator in another jurisdiction. The applicant submits a copy of their active out-of-state license, and FDEP allows roughly 30 days for the evaluation.
Collection systems
This site could not independently confirm that Florida issues a separate, stand-alone wastewater collection or transmission system operator license distinct from the treatment plant operator classes above; Florida’s own rule (Chapter 62-602) groups collection and transmission systems into the same rule as treatment facilities rather than describing a separate operator credential. Rather than assert a collection license structure that could not be directly confirmed, that discipline is left unlicensed here pending direct verification.
