PURPOSE: A rainwater collecting/recycling system for a building is provided to easily collect rainwater, to easily filter impurities from the rainwater in case of rain, and to utilize the rainwater for multi-purpose water such as flush water or water for living after purifying the rainwater. CONSTITUTION: A rainwater collecting/recycling system for a building includes a gutter (2), a screen (10), a water collection tank (20), a pump (30), a filter (40), and a water storage tank (50). The gutter at the roof or rooftop of the building is downwardly inclined, and collects rainwater in case of rain. The screen at one side of the gutter firstly removes large adulterations from the rainwater. The water collection water stores the rainwater from a first inlet pipe (12) connected to the screen. The pump pressurizes the rainwater from the feeding pipe (26) of the water collection tank at certain pressure. The filter is connected to a second inlet pipe (34) connected to a sequence valve (32), and removes organic matters and floating matters from the rainwater. The water storage tank stores the rainwater from the outlet pipe (42) of the filter. |
