And that is characterized.

In general, sewerage refers to the household sewage generated in homes, factory wastewater from factories or workplaces, and the passageway through which rainwater drains sewage collected through road drains.

In particular, the sewer flows into the river because the discharge side is connected to the river.

That is, a conventionally known sewage furnace includes rainwater silos to purify the sewage flowing into the discharge side, and includes a sewer drainage leading to a sewage treatment plant through a connection pipe connected to rainwater sills.

At this time, one or more sewage inflow holes are formed in the rainwater discharge chamber, and the sewage inflow prevention device is provided in the sewage inflow hole. In addition, the soil inflow prevention device is configured to further install a screen net to prevent foreign matters such as contaminants from flowing into the superior soil chamber.

On the other hand, the sediment inflow prevention device guides the sewage flowing into the sewage drain to the sewage treatment plant, and when the amount of sewage increases more than three times due to rainwater, the rainwater sediment is closed and discharged to the river or river.
