WW_Sewer Pressurized Mains

Sewer pressurized mains, also known as force mains, are pressurized sewer pipes that transport wastewater from lower to higher elevations, where directed gravity flow is not enough to move sewage through the sewer system. Mechanical pumps and pressure are required to influence the flow of wastewater through these pipes. Sewer pressurized mains range in size and material.
