PURPOSE: A rainwater utilization device is provided to store initial rainwater from which wastes are removed and to obtain water with high quality by preventing pollutants in collected rainwater. CONSTITUTION: A rainwater utilization device comprises a hollow cover(4), a plurality of purification units, a filtering unit(17), a dome-shaped net(7), a first overflow type precipitation chamber(12), a second overflow type precipitation chamber(15), and a brush unit(14). The purification units are installed inside the hollow cover. The filtering unit filters rainwater purified in the purification units through a filtration layer(17-a) and adsorbs the rainwater in an adsorption layer(17b). The dome-shaped net is installed inside the hollow cover and removes waste included in the rainwater flowing from a rainwater injection pipe(3). The first overflow type precipitation chamber and the second overflow type precipitation chamber precipitate minute wastes. The brush unit is formed along the outer periphery of the first precipitation chamber and collects foreign substances included in the rainwater. |
