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.
Effluent pumps are similar to sewage pumps in that they are capable of pumping waste solids - although these pumps can usually only handle solids up to 3/4 or less in diameter. The water typically being drained by an effluent pump is considered greywater as it is not sewage water, but is not clean water either.
