Which is NOT a component of a Collection System?

A sewage treatment plant is primarily part of the wastewater treatment infrastructure rather than the collection system itself. The collection system is focused on gathering sewage and wastewater from various sources and transporting it to a treatment facility for processing. Its components include lift stations, manholes, and traps, which specifically facilitate the movement and management of wastewater within the collection network.

Lift stations are key in pumping wastewater from lower to higher elevations when gravity flow is not sufficient. Manholes provide access for maintenance and inspection of the sewer lines, while traps help to capture grease and solids, preventing them from clogging the system. In contrast, the sewage treatment plant is where the actual treatment of the wastewater occurs, which is a separate process from collection.
