Question

what is the need for rainwater harvesting​

Answer 1

Water is the most important resource for any life to exist. One issue that urban India faces continuously is the water crisis. They get most of their water supply from rivers and lakes. As the local footprints dry out due to mismanagement and overuse, the search for another resource turns even more distant. The situation has an ironical turn. At one side the cities are facing severe water crisis and on the other hand they are flooded with rainwater, which is the most common source of fresh water in the monsoon. The neglected harvesting systems have simply worsened the situations. Today, the hunt for a water source and its sustainability is a big concern. One of the solutions for water crisis is capturing of this abundant rainwater through rainwater harvesting.
