The conveyor assembly (6) has a tube-like housing (7), an axle (8) driven by a motor, and a screw (9) provided on the axle (8). The conveyor assembly (6) with its axis (10) is arranged substantially vertical to convey the debris in a substantially upward direction. The separation area (2) of cylindrical shape to deposit the debris has an axis (5), an inner surface (41), a circumference, and openings (3) located about the circumference. The separation area (2) with its axis (5) is arranged in alignment with the substantially vertically arranged axis (10) of the conveyor assembly (6). The separation area (2) is connected to the housing (7) of the conveyor assembly (6), and includes an opening (17) serving as an inlet (40) for the sewage (13) into the interior of the separation area (2).
