Rainwater harvesting is the collection and storage of rainwater that runs off from rooftops, parks, roads, and open grounds. The technique of rainwater harvesting can be applied to all the three sources namely rainwater, flood water and groundwater

Note: The use of word "only" made the statements extreme and thus eliminated the inclusion of any other water source.
