Referring to fig. 1, a third valve 321 is disposed on the blowdown line 32 of the blowdown system 3. The third valve 321 can control the amount of water flowing through the waste line 32.

Referring to fig. 1, the sewage pump 31 and the sewage pipes 32 of the sewage system 3 have two sets, the sewage pipes 32 are respectively communicated with the corresponding sewage pump 31, and the two sewage pipes 32 are converged into a sewage outlet 33. When rainstorm occurs, the two groups of sewage pumps 31 can realize a forced drainage mode, and sewage in the intercepting well is forced to be drained.

Referring to fig. 1, the shell 1 is embedded into the ground, the bottom of the shell is reinforced by concrete, and the top of the shell is provided with an openable top cover 13. The shell 1 is fixed firmly, and can be overhauled through the access ladder after the top cover 13 is opened.

Referring to fig. 1, the bottom and the middle of the housing 1 are provided with liquid level sensors 5. The level sensor 5 may be used to monitor the water level in the vatch basin.
