California State University Sacramento (CSUS) Course Change

On Sept. 20, 2019, CSUS changed its enrollment of the Operation of Wastewater Treatment Plants Volume I. The Operation of Wastewater Treatment Plants Volume I is also divided into multiple enrollments. These enrollments are A, B and C.  Students must complete all three enrollments in order to meet the DEP requirements for completion of Volume I.  

On Nov1, 2022, CSUS dramatically changed its enrollment of the Operation of Wastewater Treatment Plants Volume II. The new Operation of Wastewater Treatment Plants Volume II, 8th Edition, is now divided into two separate enrollments (Enrollment A and Enrollment B). A student must complete both Volume II enrollments (A and B) in order to meet the DEP requirements for completion of Volume II.   

In summary, certificates of completion for both Volume I (all enrollments A, B and C) and Volume II (all enrollments A and B) are required to obtain eligibility to sit for the Wastewater Class C examination.  

GED Acceptance

DEP's Operator Certification Program accepts only general educational development (GED) issued by the American Council on Education through an approved GED administrator. In Florida, the approved GED administrator is the Florida Department of Education through its network of public schools and adult education centers. (Please note: Depending on your location, some testing centers are paper- or computer-based. Enter your ZIP code under Testing Center Information.)

Licensing Process

Florida statutes require that anyone who operates a drinking water treatment plant, domestic wastewater treatment plant and/or water distribution system be licensed by DEP. To qualify for licensure, an applicant must meet minimum educational and work experience requirements for each class of license. A passing score is required on the exam for the type and level license desired.

Step 1: Apply for Exam - I have completed my approved training course and I am ready to take my exam.

  • Examination Information – Applications, deadlines, fees, locations, handbooks and reference material.
  • Veteran Services – The Department of Veteran Affairs offers reimbursement of fees associated with professional licensure exams to qualified veterans. Please contact that agency for more information.

Step 2:  Apply for License - I have taken and passed my Florida exam and I am ready to get my license.

Renewal Information

If you have not completed your required amount of continuing education, you should begin making arrangements now! Please do not wait until the last minute when all classes are full and unavailable. You can search the status of your Continuing Education Units (CEUs).

Please note that the splitting of CEUs is prohibited. An example of this would be a management course worth 4.0 CEUs. These CEUs cannot be split into 2.0 for water and 2.0 for wastewater if you are dually licensed. If you have any questions regarding this, please call the Operator Certification Program at 850-245-7500.
