Show answer
Correct Option: A
Explanation:
Tamil Nadu is the first and the only state in India which has made roof top rain water harvesting structure and is compulsory to all the houses across the state. The harvesting of rainwater simply involves the collection of water from surfaces on which rain falls, and subsequently storing this water for later use. The practice has been patchy in many parts of the country, but Tamil Nadu’s experiment with the alternative water conservation technique is a rare success story.
The Rain Water Harvesting (RWH) scheme, Tamil Nadu chief minister J Jayalalithaa, was launched in 2001 in a bid to rejuvenate water sources and improve ground water levels in the parched southern state.
