Water & Wastewater System Operator Licensing

A Licensed Operator is the individual approved by the DEP holding any local title, designation, or job description who is on-site at a system a significant amount of time, although not necessarily full time, and who has active involvement in and is responsible for the operation, maintenance, and effectiveness of the system, and who holds a license equal to or higher than that required for the system.  Applicable systems include:

  • Industrial Wastewater Treatment System (N License)
  • Public Wastewater Collection System (C License )
  • Public Wastewater Treatment System (S License)
  • Public Water Distribution System (W License)
  • Public Water Treatment System (T License)
  • Very Small Water System (VSWS License)
Eligibility for a Licensed Operator in New Jersey requires a combination of experience, educational course prerequisites and passing an exam.  Maintaining a license requires completion of continuing education every three-year recertification period or successful retesting.  These processes are managed by the DEP with expert guidance from the Board of Examiners and the Advisory Committee on Water Supply and Wastewater Licensed Operator Training.  The Board of Examiners assists with all licensing-related matters while the Advisory Committee focuses primarily on the instructional process for required courses and continuing education classes.

In-Person Licensing Examinations Update

Effective January 6, 2023, New Jersey will switch from the use of remotely proctored exams to exams administered at testing centers. View more details about the announcement here.

Training Contact Hour (TCH) Waiver for Licensed Operators

The NJDEP has issued a proportionate credit waiver for licensed water and wastewater operators for the current licensing cycle that ends on September 30, 2021. View to the announcement here.

An actively-monitored email address is REQUIRED for all DEP and exam vendor (PSI) correspondence and service updates – to eliminate paper use and postage, and reduce delays, letters will NOT be mailed. The DEP contact for exam/licensing general questions and to provide a new/updated email address is; PSI should be contacted directly for exam scheduling at (833) 256-1420. The $70 non-refundable application fee is required for the initial exam and every time a three-time failure refresher course completion certificate is submitted to DEP for reexamination eligibility.

Pursuant to the instructions of the Statement of Qualifications (SOQs), the Exams and Licensing Unit and the Water and Wastewater Board of Examiners would like to further remind all licensed operators in the State of New Jersey, to obtain the signature of ALL DEP-recognized Licensed Operators in Charge under whom you have ever worked. Recently, some examination application SOQs were rejected or conditionally approved due to the fact that the signature of the Licensed Operator in Charge during certain specified work experience time periods could not be obtained or otherwise verified. The current license operator in charge can only certify the time period in which you worked under his/her purview. Thank you for your attention to this matter. View PDF Here


Be advised that due to staff limitations related to the COVID 19 health emergency, processing and mailing of water and wastewater licenses may experience significant delays. Please allow 6 to 8 weeks for license arrival via mail. During that time as always, you may access and print the status of your payment and license. This printed information will be honored by enforcement inspectors until such time that your actual license is received. To find and print your license status use Online Reports.  There are two reports that will provide your license status:

The Department is pleased to announce exam opportunities will be available for those applicants previously scheduled and later cancelled due to the COVID emergency. This is possible through new arrangements with the Association of Boards of Certifications (ABC) and the testing service PSI that will provide computer-based testing at sites in and beyond NJ. Individuals who were cancelled will be contacted directly by PSI on or about November 20th to reschedule. In addition to the Department’s non-refundable $70 application administrative review fee, all exams will require a nominal fee of $102 per exam paid directly to PSI to support the new modality which provides safety as well as increased exam dates and times. Please do not call or email the Department for exam info. PSI will be the primary contact for all exam-related scheduling going forward and instructions and appropriate contact will be in the initial emails. If you were previously scheduled for an exam and do not receive an invitation from PSI to reschedule by Tuesday, November 24th, please email with the subject “Reschedule”, include your name and license number, if available. Applicants for July and October 2020 or any future exams remain on hold and new applications are not being accepted at this time.  Instructions will follow in an updated alert at this site when submittal of new applications may resume. For those already approved, confirmed and then cancelled for March/April exams: You should have already received email instruction direct from PSI on re-scheduling an exam.  You should also be getting an update to those instructions that accounts for whether or not you have already scheduled an exam.  The update email instruction will reflect a transition of all exams to online remotely-proctored only.  Computer-based testing has been discontinued due to minimal exam slot availability.  We appreciate your patience as we continue to adapt the program to evolving demands and constraints. ONLINE/REMOTE TRAINING CONTACT HOURS (TCHs) Please be advised of the following update regarding online/remote courses and webinars and the 3-year license recertification cycle that ends on September 30, 2021.
