About this Exam
Prepare with the ADEQ Wastewater Collections 2 Practice Test practice quiz. This question bank includes 10 questions covering many, part, ladder, adeq, and wastewater. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.
Sample Questions
Question
1
The top of the ladder must extend how many inches above the top of the trench?
Explanation:
Extending the ladder at least 3 feet above the trench top gives you a solid handhold and a safe transition from the ladder to the edge. That distance is 36 inches, so 36 inches is the correct extension. Shorter extensions provide too little ladder above the edge for a secure grip, making it harder to climb out, while a longer extension (like 48 inches) would still be acceptable but isn’t needed to meet the minimum requirement.
Question
2
A lead gasket used with a chlorine cylinder can be reused how many times?
Explanation:
Lead gaskets used with chlorine cylinders are intended for a single use. The seal forms by the gasket deforming to fit the valve seat when the cylinder is closed. Once removed, the gasket’s surface can be deformed, cracked, or develop micro-tears, and it won’t seal reliably if put back in place. Chlorine gas is highly reactive and corrosive, so any small imperfection or residual material on the gasket can lead to a leak under pressure. Because a leak of chlorine poses serious health and safety risks, the gasket is replaced with a new one each time the cylinder is serviced. In short, you should never reuse it.
Question
3
Which of the following is part of the collections system?
Explanation:
The main idea here is recognizing which components belong to the wastewater collections system—the network that gathers and conveys sewage toward the treatment facility. An interceptor is a large-diameter sewer that collects flow from smaller sewers and moves it toward the treatment plant. This is exactly the type of conveyance equipment that defines the collections system, since its purpose is to transport wastewater rather than treat or store it. A digester, lagoon, and clarifier, on the other hand, are associated with treatment: a digester breaks down organic matter anaerobically, a lagoon serves as a treatment or storage pond, and a clarifier removes solids as part of the treatment process. So they belong to the treatment side rather than the collection network.
Question
4
Where is the bubbler tube open end found?
Explanation:
Bubbler level measurement works by keeping the tube’s open end submerged in the liquid whose level you need to know so that hydrostatic pressure in the tube matches the liquid depth. In a wastewater system, the area that actually contains the liquid and varies with flow is the lift station wet well. Therefore the open end of the bubbler tube sits in the wet well, not in a dry well or in an air vent or on a truck. This is why the lift station wet well is the correct location for the bubbler tube’s open end.
Question
5
How often should manholes be inspected in sewer mains that are not cleaned annually?
Explanation:
Maintenance timing for manholes is tied to how often the sewer mains are cleaned. When cleaning isn’t done annually, inspecting every two years is the practical balance that still catches developing problems—like sediment buildup, cracks, or misaligned frames—without overburdening resources. An annual inspection would be more than needed for this scenario, while much longer intervals (five or ten years) could allow issues to go unnoticed. Biennial inspections provide a reasonable, proactive check aligned with the reduced cleaning frequency.
