Texas Wastewater Class A Practice Exam 2025 – 400 Free Practice Questions to Pass the Exam

The requirement for a collection system that averages 1.0 million gallons per day (mgd) or more is to have it operated by personnel who possess the appropriate certification levels due to the complexity and potential environmental impact of managing such a system. A Class III Collection operator or a Class B Wastewater operator have the necessary knowledge and skills to effectively manage and oversee collection systems of this capacity.

Class III operators are trained to handle more complex systems and understand advanced operational practices that are critical for ensuring compliance with regulations, managing the flow of wastewater, and maintaining the infrastructure of the collection system effectively. Similarly, Class B Wastewater operators are educated in both the operational and mechanical processes associated with wastewater management, including collection systems.

In contrast, a Class I operator, while certified, may not possess the training needed for the larger systems. A licensed engineer has a different focus and is not necessarily equipped with the day-to-day operational knowledge required for effective collection system management. Technicians may assist but do not hold the specific certification needed for this responsibility. Therefore, the requirement for a Class III Collection operator or a Class B Wastewater operator ensures that the collection system is in competent hands.
