What is the line leaving a pump station called?

• A. Lateral
• B. Force main
• C. Sewer line
• D. Discharge line

Answer: (B)

The line leaving a pump station is the force main because once the pump pushes wastewater out, that flow is under pressure and travels through a pressurized pipe to the next part of the system. The term force main specifically describes this pumped, pressurized discharge path, distinguishing it from gravity lines or other service pipes. Lateral refers to a service connection to a property, not the pumping discharge. A sewer line is a general term for any sewer pipe without indicating its relation to a pump station. A discharge line could apply in a broad sense, but the standard, precise name for the pumped, pressurized outlet is force main.
