Rain water harvesting is collecting and storing of rain water so that it can be used in future. Roof top rain water harvesting is one of the commonest methods employed for conserving rain water.

In rooftop rain water harvesting the top of the roof of the building acts as catchments for rainwater. This rainwater is then transported via pipeline to underground reservoir or tank,where it is stored. This water can be used for many purposes like irrigation, washing, for drinking by livestock. This method is very inexpensive and can be used with ease.
