The present invention relates to an automatic and semi-automatic combined-use storage system for preventing an initial storm that has not been purged due to an initial storm supercharged in a rainy season due to exceeding a maximum treatment capacity of a sewage end- In Hase, the sewage discharged through the sewer pipe is guided to a sub-tank, and a series of processes are performed. When the water level in the sub tank rises during the rainy season, the initial storm is stored into the inside of the tank. On the other hand, Semi-automatic (automatic and driven) so that the initial storm can be delayed and discharged into the secondary structure.

Generally, in the case of new cities, it is not necessary to use the excellent soil because all the sewage is directly sent to the sewage treatment plant by using the sewerage system which constitutes sewage and stormwater as separate pipes. However, in many existing cities, The sewer pipe is drained through the sewer pipe.

Therefore, in order to reduce the burden on the sewage facilities in case of rainy weather,

These excellent toilets are a facility for collecting a certain amount of sewage and initial storm on a daily basis from a combined sewer pipe and discharging it to the sewage end treatment plant and discharging the remaining clear stormwater to the waters such as rivers.

In the case of natural rainfall as in the case of rainy weather, when the flow rate due to stormwater (rainwater) becomes three times or more of the normal amount of wastewater, It will be discharged into rivers and the sea.
