As a result of water pollution, the available clean water becomes less and water shortage has become a worldwide problem.  Rainfall is a source of clean water, and it is meaningful to collect it in a scientific and effective approach.  At mountain area, it is inconvenient to construct tap water treatment facilities or transport the tap water to highland.  But, the mountain area is abundant in rainwater, which can be collected and supplied as a water source to meet local people’s demand for domestic water consumption.  At urban area, the rainwater can be collected & stored systematically, and then supplied as a water source for irrigation, toilet flushing, vehicle washing, or as a supplement source for scenic water.  Considering the multiple applications of collected rainwater, Washine has introduced two models of rainwater collectors, namely wall-mounted version and floor-standing version.

Collection procedures：impurity separation → primary rain discharge → filtration → rainwater collection → rainwater storage → water supply as per different quality levels.

1. impurity separation： After being collected at the rooftop, the rainwater will run downwards through the rainspout together with big impurities like leaves and tresses, which will be separated by filtering net, and the rainwater will enter the collector.

2. Primary rain discharge： As an outdoor location, the rooftop is subject to pollution.  The rain that washes away the dust, dissoluble & indissoluble impurities on the rooftop is called primary rain, and should be discharged away directed.

3. Rainwater collection as per different quality levels： As the rain continues to fall down, the rainwater will go through the driver-free filter and reach the 1^st collector.  During this process, rainwater is filtered, the impurities with a diameter over 2mm are separated, and the rainwater in the 1^st collector can be used to water flowers and wash the ground; the water entering 2^nd collector can be used for domestic use, for example, toilet flushing, bathing, clothes washing, etc.; the water entering storing container can be supplied directly as drinking water if being sterilized or boiled.
