This book was created to help aspiring wastewater treatment operators in Texas prepare for the Texas Commission on Environmental Quality (TCEQ) Class C Wastewater Treatment License Exam. It provides a comprehensive set of unofficial practice questions designed to reinforce essential knowledge, test your understanding of key concepts, and boost your confidence before taking the real exam.
The Class C license is an important step for professionals working in wastewater treatment facilities. Operators at this level must demonstrate a solid understanding of wastewater processes, treatment plant components, safety protocols, and state regulations. This book is meant to complement—not replace—official TCEQ materials, training manuals, and hands-on experience.
