A wastewater-lifting system is provided. The wastewater-lifting system includes at least one bulky-material-collecting vessel for wastewater loaded with bulky materials which is guided therethrough, a liquid-collecting vessel for the wastewater which is freed from bulky materials and precleaned in the bulky-material-collecting vessel, and with a wastewater shaft for accommodating the bulky-material-collecting vessel and the liquid-collecting vessel. The liquid-collecting vessel and the wastewater shaft have at least one common wall surface. The liquid-collecting vessel defines a closed-off space with only a partially covered base surface in the wastewater shaft, and is equipped for this purpose with at least one wall surface independent of the wastewater shaft.
