Which of the following components is not typically part of a wastewater collection system?

A water treatment plant is not considered part of a wastewater collection system because its primary function is to treat wastewater, making it safe for discharge or reuse. The wastewater collection system, on the other hand, includes components that transport wastewater from the point of generation to the treatment facility.

Pumping stations are crucial elements of the collection system as they help to move wastewater through the system, especially in areas where gravity flow is not feasible. Manholes are essential access points within the sewer network that allow for maintenance and inspection of the system. Sewers are the primary conduits for transporting wastewater from homes and businesses to treatment facilities. Therefore, while all other components serve the role of collecting and moving wastewater, the water treatment plant serves a separate function focused on treatment rather than collection.
