Description

TECHNICAL FIELD [0001] The present invention relates to a water collecting apparatus and an excellent reuse apparatus including the water collecting apparatus and the water re-

The present invention relates to a water collecting apparatus for collecting rain (rainwater) and an apparatus for treating the rain water for reuse.

Water is one of the essential factors for man to survive and live. However, there is a shortage of water in the world as well as in Korea, and various water reuse schemes are suggested to solve this water shortage problem. In particular, reusing stormwater has been done for a long time by mankind, and it is not difficult to confirm reuse of stormwater in everyday life.

Collected stormwater can be reused as water when properly treated, but there is a lack of effective collection and treatment of stormwater at present. For example, in terms of the treatment of stormwater, various contaminants present in the atmosphere are washed away from stormwater and contained in the stormwater. Therefore, when stormwater stormwater can not be appropriately treated, it is difficult to reuse the storm water.
