The vertical pipe is connected through a long vertical suction pipe to the inlet port of the sewage pump. Floating material on the filthy water can be sucked into the first and then second inlet openings of the vertical pipe for along time required for the water level of the filthy water to change from a level slightly higher than the first inlet opening to another level adjacent to the lower end of the second inlet opening.
