What Does Sewer Force Mains Mean?
Sewer force mains are used where gravity is not enough to move sewage or storm water runoff through a sewer line. Force mains are fitted with pumps at lifting stations that help convey the wastewater from a lower elevation to a higher elevation. Force mains act as a support system for wastewater sewer lines that are installed in low lying areas with treatment plants situated at an elevation requiring pumping to convey sewage forward.
