Abstract
A wastewater-lifting system and a method for operating a wastewater-lifting system guides wastewater loaded with bulky materials into a bulky material collection tank having at least one separating screen. During intake of wastewater, the bulky materials are retained in the bulky material collection tank and pre-cleaned wastewater passes into a liquid collection tank via a connection line and one or both of a pump and a bypass line connected to the connection line. During the wastewater intake a pivoting flap in the connection line closes flow to the pump except for a flushing cross section, and opens the bypass line. During a pumping operation, the pivoting flap opens the connection line from the pump and closes the bypass line.
