Describe any three different rainwater harvesting prescribed in India.
Different rainwater harvesting systems practised in India:
- In the semi-arid and arid regions of Rajasthan, all houses had underground tanks or tankas for storing drinking water. The tanks wire connected to the sloping roofs of the houses through a pipe. Rain falling on the rooftops would travel drown the pipe and was stored in these underground tankas.
- In the western Himalaya’s diversion channels called ‘guls’ or, ‘kuls’ are built to utilize rainwater for agriculture.
- In arid and semi-arid regions of Rajasthan agricultural fields were converted into rain fed storage structures. Rain water was allowed to stand and moisten the soil. These structures are called ‘Khadins’ and ‘Johads’.
