This advanced 2-day Wastewater A & B Exam Preparation class is designed for experienced operators preparing for EGLE’s higher-level certification exams. Built around comprehensive A & B exam reference materials, the course delivers an in-depth review of complex treatment processes, including primary, secondary, and advanced biological treatment, nutrient removal, disinfection, solids handling, digestion, and dewatering. Emphasis is placed on understanding process control, operational decision-making, and the calculations operators are expected to master at the A & B level.

Over two focused days, participants will work through advanced calculations, troubleshooting scenarios, and “need-to-know” exam topics covering activated sludge, attached growth systems, pumps and hydraulics, laboratory analysis, and regulatory considerations. This class is ideal for operators seeking a deeper technical understanding, refined problem-solving skills, and the confidence needed to successfully pass the EGLE Wastewater Operator A & B Exams.

This comprehensive 3-day Wastewater C & D Exam Preparation class provides an in-depth review of the core knowledge and skills needed to successfully pass the certification exam. Using structured workbook materials, the course walks participants through calculations, treatment processes, laboratory analysis, maintenance, safety, and regulatory concepts that are critical for day-to-day operations and frequently tested on the exam.

Over three days, attendees will have the time to slow down, ask questions, and work through detailed examples and practice problems that reinforce understanding and retention. Designed for both first-time test takers and experienced operators seeking a thorough refresher, this class delivers a well-rounded, confidence-building approach to exam preparation.
