Abstract
Description
Field of the Invention [0002] The present invention relates to a rainwater storage system, and more particularly, to a rainwater storage system that effectively separates rainfall at an early stage, removes foreign matter contained in rainwater, and reusably stores the rainwater.
Urban floods and droughts are emerging as an environmental problem. Developed countries are interested in rainwater harvesting and infiltration as one of the ways to solve urban flood and restore the environment, which is understood as an environmentally friendly and sustainable technology. In addition, the stored rainwater is used for life-giving water, fire-fighting water, etc., and is also used for groundwater recharge. In case of a disaster, it is also used as emergency drinking water.
Until now, public perception of rainwater has been centered on dimensions. In other words, rainwater has been of interest only as soon as it has fallen out of the sewer and must be quickly removed from the sewer system. However, flood damage is increasing due to the lack of capacity of these facilities due to heavy rainfall due to weather and urban development. Without such measures, the damage will be more serious in the future.
The annual rainfall in Korea is 1,274mm, which is higher than the world average of 974mm. However, since Korea has a high population density, the average per capita use is 2,755m3, which is only 12.5% of the world average of 22,096m3. In the United Nations' International Agency for Population and Behavior Studies, if the annual amount of water available per capita is less than 1,000 cubic meters, it is classified as a water-famed country, while 1,000 to 1,700 cubic meters is classified as a water-scarce country.
The water-famed country includes Singapore and the Middle East countries. Korea has 73.1 billion cubic meters of water available per year, and 1,550 cubic meters of water per person, which is included in the category of water shortage along with the UK and Belgium.
In addition, in the case of our country, since the precipitation is concentrated in the summer season and the seasonal variation is large, the fluctuation of the river flow rate is very high and it has a natural condition adverse to water resource management. In other words, two-thirds of the annual precipitation is concentrated in the rainy season and typhoon period of June to September, which is the flood season, and only one-fifth of the annual precipitation is recorded for six months from November to April of next year. Unlike foreign countries, floods and droughts are frequent.
In addition, since 65% of the land is mountainous and the topsoil layer of the soil is thin, the flood water is discharged at a time due to the low water conservation ability of the watershed and the slope of the river. The ratio is about 300 ~ 400, which is more than 10 times that of foreign countries.
Therefore, the use of rainwater is very important in terms of social aspects as well as water conservation on an individual level. Therefore, in order to prepare for water shortage in the future, it is necessary to change the social perception of rainwater use and R & D.
The present invention meets the social necessity of the use of rainwater, and it eliminates the rainwater collected at the early stage of the rainwater collected from the water surface without using any additional power, removes the foreign matter contained in the rainwater, .
The rainwater storage system according to the present invention is intended to solve the following problems.
First, we want to expand the tanks that store the rainwater collected through the surface of the house in parallel according to the purpose.
Second, we want to make it easier to manage rainwater storage tanks.
Third, the initial rainwater collected from the surface of the house should be stored in a separate early storm drainage section so that initial rainwater can be excluded, stored and used.
Fourth, we want to filter and store large foreign matter such as fallen leaves, etc. contained in rainwater collecting and fine foreign matter such as soil.
Fifth, it is possible to combine the initial excellent excretion part and the screen part in various forms so that the construction can be conveniently performed according to the installed environment.
The solution of the present invention is not limited to those mentioned above, and other solutions not mentioned can be clearly understood by those skilled in the art from the following description.
The rainwater storage system according to the present invention is a rainwater storage system including an initial canal discharge unit for receiving rainwater from a water collecting surface to separate initial rainwater and a screen unit for removing foreign matter in rainwater, A rainwater inlet formed at one side or the other side of the storage tank housing to receive rainwater from the screen portion; a rainwater outlet formed at the other side of the storage tank housing to discharge rainwater stored in the storage tank housing; And a rainwater discharge port formed at a center side of the housing and spaced apart from a bottom surface of the storage tank housing, wherein one side surface and the other side surface of the storage tank housing are formed in a flat plate shape.
