Rooftop rainwater collection systems are designed to capture rainwater and transported through gutters and other pipes into cisterns or tanks, where it is stored until needed. The water collected can be used for irrigation, laundry, hygiene, or even potable water, depending upon the materials used and the treatment undertaken by the building owner.
