lift station

A wastewater pumping station that lifts the wastewater to a higher elevation when continuing the wastewater collection line at reasonable slopes would involve excessive depths of trench. Also, an installation of pumps that raise wastewater from areas too low to drain into available pipes. Lift stations may be equipped with air-operated ejectors or centrifugal pumps. Sometimes called a pump station, but this term is usually reserved for a similar type of facility that is discharging into a long force main, while a lift station has a discharge line or force main only up to the downstream gravity collection pipes. Throughout these manuals when we refer to lift stations, we intend to include pump stations.
