[0002] The rain and sewage shunting drainage structure refers to the structure that rainwater and sewage are discharged through different pipeline systems respectively. According to the different rainwater discharge modes, the shunting drainage system is mainly divided into complete shunting system, incomplete shunting system and half shunting system.

Subsequently, when the rainwater season comes or the rainwater pipe needs to be opened for shunting, the sludge, impurities and the like originally deposited at the bottom of the sewage pipe may be washed and carried into the rainwater pipeline by rainwater, and finally discharged into the natural river together with rainwater. This phenomenon not only pollutes the river water quality, but also may affect the living environment of aquatic organisms, and even poses a potential threat to the downstream drinking water source.
