Recently, the most important issue in the world is the environment. In particular, the problem of water shortage has been highlighted. However, it is difficult to secure stable water resources due to the weather and global warming, and the water quality is seriously polluted by wastewater and domestic sewage generated as the industry develops highly. Water shortages are also taking place as the groundwater becomes depleted.

On the other hand, our country has been recognized as abundant in water resources from the past, but due to the nature of Korea 's terrain, which is highly inclined, it is not excellent and is rapidly lost.

In addition, the annual precipitation in Korea reaches 126.7 billion tons. The average annual precipitation in Korea is 1.3 times that of the world average, but annual precipitation per capita is one tenth of the world average. Two-thirds of the rainfall is 6 ~ Under the condition that it is concentrated in the rainy season of August and the topsoil is thin and the natural desalination capacity is poor, the total amount of water used has increased 6.5 times since 1965 and the use of domestic water has increased 32 times. It is obvious that the shortage of water resources will become more serious considering the increase in population, the amount of water needed for industrial development and agriculture.

Therefore, an alternative to this water shortage is to collect stormwater rainwater and use the stormwater stormwater if necessary after the storm. It is not easy to collect stormwater efficiently, and it is difficult to collect stormwater efficiently in Korea where the four seasons are clear and rainfall is concentrated in summer Collecting is never easy.

Another problem is that since the pollutants in the air are contained in the pollutants in the rain or in the rain, the use of the pollutants in the natural state is a cause of secondary pollution of water quality.

In order to solve the above-mentioned problems, there has been proposed a system in which rainwater falling on a roof of a building flows along an inflow pipe having an initial rainwater removal device to collect impurities and collect water, A treatment water tank and an air filtering device provided adjacent to the storage tank to supply purified water to the outside through the supply pump, and to supply the purified water to the outside through a supply pump; , A power source oscillator, an automatic discharge device and a flow control device, and a central control device for centrally controlling the discharge device.
