Hi, Friends
Rainwater harvesting is simplest way to avoid water crisis , the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), a reservoir with percolation, so that it seeps down and restores the ground water.
