PROBLEM TO BE SOLVED: To provide a belt gate with a hopper for sewerage having an excellent sealing between the hopper and the opening/closing device thereof and capable of preventing leakage from the hopper and a sewage leak preventive device. SOLUTION: In this hopper for sewerage, the belt gate 2 allowing a discharge port to be opened and closed and having a partition wall 5 surrounding the periphery of the discharge port is installed at the discharge port of the hopper for sewerage 1. Washing water is fed to an annular groove 9 formed of the partition wall 5 surrounding the discharge port. A water supply and drain device for discharging the supplied washing water is installed in the partition wall 5. Thus the sewage from the hopper for sewerage 1 can be prevented from leaking.
