RAIN WATER HARVESTING

The rainwater harvesting simply involves the collection of water from surfaces on which rain falls, and subsequently storing this water for later use. Water is collected from the roofs of buildings and stored in rainwater tanks. Water can also be collected in dams from rain falling on the ground and producing runoff.
