You made the decision that it is time to upgrade your Water Treatment Plant Operator Certification. Now what? Even if you have been working in the field for years, taking the certification exam can be unnerving and requires a lot of preparation. Studying drinking water 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 live online “Review & Exam Prep for Water Treatment Plant Operator Level 3 & 4” workshop consists of six sessions, totaling 21 hours over a two-week period.

This workshop is perfect for operators who are working on taking their level 3 or 4 certification exam. We 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 especially address the higher level and more complex principles, processes, challenges, and calculations involved in drinking water treatment. We will:

• review:
  • • Water system components
    • Safe Drinking Water Act regulations
    • Sample collection
    • Disinfection
    • Fluoridation
    • Water storage
    • Basic distribution system components & operations
    • Pumps, motors, and mechanical systems
    • Principles of Groundwater systems
    • Principles of Surface water systems
    • Safety

• explain how to make sense of word problems and determine how to obtain the correct answer
• address math formulas as they apply to water systems and practice complex, advanced level calculations
• 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 21 hour live online “Review & Exam Prep for Water Treatment Plant Operator Level 3 & 4” 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 Drinking Water 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 water math we would strongly encourage you to also take our Math Review & Exam Prep workshops.
