A centrifugal pump is the most commonly used wastewater pump. They are used most commonly for raw wastewater pumping; at lift stations, recirculation flows, for return activated sludge, waste activated sludge, and final effluent pumping.
Stainless steel guide rail systems can be useful in the deeper stations. Special submersibles, called grinder pumps, are suitable for pressurized sewage system applications. The two generic types of lift station designs are wet well and wet well/dry well. The wet well/dry well type uses a wet well or pit to collect wastewater and a companion dry well which contains the pumps, controls, and related equipment.
