Which activity is part of maintaining and repairing equipment associated with the collection system?

• A. Treat wastewater
• B. Inspect treatment plants
• C. Maintain and repair equipment associated with the collection system
• D. Design new sewer lines

Answer: (C)

Maintaining and repairing equipment linked to the collection system is all about keeping the network’s components—like pumps, valves, lift stations, screens, and access points—in good working order so wastewater moves reliably and doesn’t back up or overflow. The main idea is to perform routine upkeep and fix issues before they become failures: inspecting for wear or corrosion, greasing moving parts, replacing worn bearings or seals, clearing blockages, tightening connections, repairing leaks, and testing alarms or controls. This keeps the conveyance system functional and reduces the risk of service disruptions.

Other activities listed relate to different parts of the wastewater system. Treating wastewater happens at the treatment facility after it leaves the collection system, so it’s not about maintaining the pipes and appurtenances. Inspecting treatment plants is about the treatment process itself, not the collection network. Designing new sewer lines involves planning and expanding infrastructure, not the routine upkeep of existing equipment.
