Solution
Rainwater harvesting is a method of direct collection of rainwater from rooftops of buildings. It can be done on the rooftops of houses as well as industries.
How rainwater harvesting helps to solve the water problem:
The rainwater collected can be stored for direct use or can be allowed to reach the groundwater.
Once the water reaches the groundwater, water table is raised.
Rainwater harvesting is therefore a solution to the problem of depleting groundwater.
The collected rainwater can also be used for different household and industrial uses, thus reducing the problem of overuse of water.
