The original Wensheng Drainage Culvert containing the black and odorous water is equipped with the confluence drainage pipeline, which increases the processing load of sewage treatment plant in rainy days with the water body polluted by the overflow sewage. The modified drainage culvert ensures the stable sewage load and provides a good living environment for residents on both sides of the river.

Wensheng Drainage Culvert subjected to repair (construction) is about 6km long. The culvert modification achieves the separation of rainwater from the original confluence drainage pipeline and Introduction to the Wensheng Drainage Culvert, with the culvert sewage diverted to the sewage pipeline. The total investment is about RMB 80 million.
