Question

Name and explain any one way by which the underground water table does not go down further.

Answer 1

Underground water table can be recharged through rainwater harvesting. Rainwater harvesting is a process by which rain water is collected and stored for the purpose of recharging the ground water or for future use like for irrigation and agriculture, for livestock, etc.  In India, rainwater harvesting is an old tradition, which is followed till now in many parts of India. For example, bawris are traditional architectural rainwater harvesters that were built for collecting water, in the state of Rajasthan. ​
There are two ways of rainwater harvesting:
(i) Surface runoff harvesting: In urban areas, rain water that flows away from the surface can be collected and used for various purposes.
(ii) Rooftop rainwater harvesting: The rainwater on the roofs of the buildings is collected through canals that drain the water into ground reservoirs. This stored water is later utilised.
