Answer 1

Answer:

Rainwater harvesting is a simple and economical way of preserving rainwater that falls on earth. It involves collection of rainwater on the roofs of the buildings and storing it underground for later use.

Rainwater harvesting conserves valuable groundwater. It allows the rainwater to seep into the ground more efficiently by constructing percolation pits and recharge wells. It raises the water level in the wells and borewells that are drying up, thereby solving the problems of water scarcity.
