It relates to stormwater sewage of the combined sewerage to facilitate the treatment.

In general, the combined or classified rainwater toss is a structure that separates and discharges rainwater, sewage and sewage, and is often installed near the discharge area so that rainwater does not flow over the planned sewage to the sewage terminal treatment plant. The installation location should be well selected because it has a volume of.

In general, "super soil" means "a facility for collecting a certain amount of sewage in rainy weather from a confluence sewage system, transporting it to a sewage treatment plant, and discharging the remaining sewage into water bodies such as rivers."

In Korea, most of the above-mentioned contaminated sedimentary soils are installed, and since a large amount of sediments such as earth and sand are accumulated in the interior, a predetermined period of time is cleaned every year.

As described above, the general contaminated or classified rainwater silos are mostly installed before the 80's in the case of the confluence, and in the case of the classification, most of the sewage and rainwater in the new development site after the 80's are treated as separate pipes. It is being used accordingly.
