You made the decision that it is time to take your Wastewater Operator Certification Exam. Now what? Whether you are new to the field or have been working in it for years, taking the Certification Exam can be unnerving and requires a lot of preparation. Studying wastewater treatment manuals, talking to other operators, learning test taking skills . . . these are all great steps that will help you successfully pass your exam. Exam Prep classes are great opportunities to hear about what to expect from the exam, refresh your knowledge, identify your strengths and weaknesses, learn from fellow operators how they were successful with taking other exams, and more.

Our three day “Review & Prep for Wastewater Operator Level OIT, I & II Certification Exam” workshop is perfect for operators who understand the principles of wastewater treatment and are interested in obtaining their Wastewater Operator level OIT, I or II certificate. This class will explain what to expect from the exam and help you identify areas you may want to focus on during your exam prep activities.

In this workshop we will also:

  • review the principles of:
    • basic collection systems
    • pump stations
    • preliminary treatment
    • primary treatment
    • secondary treatment
    • tertiary treatment
    • disinfection
    • sludge handling
    • sample collection
    • basic wastewater laboratory tests, equipment, and skills
    • wastewater safety
  • tour a WWTP to see how the material covered in the workshop is used at a WWTP
  • explain how to make sense of word problems and determine how to obtain the correct answer
  • address math formulas as they apply to wastewater treatment
  • provide many opportunities to practice and solve problems typical of those encountered on certification exams
  • share tips for how to prepare yourself for the exam
  • explore test taking techniques


This three-day “Review & Prep for Wastewater Operator Level OIT, I & II Certification Exam” workshop will help you move your thought process from operation mode into the “test taking mode” and boost your confidence in your ability to pass the exam.


Since Wastewater Operator Certification Exams require knowledge across a very complex and wide area, general exam prep classes are fast paced and do not allow for in depth discussions and explanations; instead, they focus on review and practice questions. For those who are struggling with wastewater math we would strongly encourage you to also take our “Math Review & Exam Prep for OIT and Level I & II Operators” workshop. Based on your background you may also want to consider taking additional classes that explain specific topics such as our “Taking the Mystery out of Pumps”, “Sample Collection & Sampling Plans”, “Biosolids Treatment” workshops.
