The subject of the present invention is a wastewater-lifting system (1) which is equipped with at least one bulky-material-collecting vessel (2) for wastewater which is guided therethrough and loaded with bulky materials, also with a liquid-collecting vessel (3) for the wastewater which is freed from bulky materials and precleaned in the bulky-material-collecting vessel (2), and with a wastewater shaft (8) for accommodating the bulky-material-collecting vessel (2) and the liquid-collecting vessel (3). The liquid-collecting vessel (3) and the wastewater shaft (8) have at least one common wall surface (9, 10). According to the invention, the liquid-collecting vessel (3) defines a closed-off space with only a partially covered base surface (9) in the wastewater shaft (8) and is equipped for this purpose with at least one wall surface (11, 12) independent of the wastewater shaft (8). |
