Which structural component of a sewage lift station carries wastewater to the nearest manhole for gravity flow?

The force main is the structural component that carries wastewater from a sewage lift station to the nearest manhole for gravity flow. When the wastewater is pumped from the wet well, it travels through the force main, which is a pressurized pipe designed specifically for this purpose. The force main ensures that the wastewater can be transported efficiently over any difference in elevation until it reaches a point where it can flow by gravity into the main sewer system or manhole.

This component is critical for the functioning of a sewage lift station, as it allows for the movement of wastewater uphill or over long distances where gravity alone would not suffice. Understanding the role of the force main is essential for effective maintenance and operation of sewage systems, as it directly impacts the flow and management of wastewater.
