Discuss how the rainwater harvesting in semi-arid areas of rajasthan is carried out
Answers
(i) In semi-arid regions of Rajasthan every house had underground tankas to store the water for drinking purposes.
(ii) These tankas are large and deep which were built inside the main house or the courtyard.
(iii) They were linked to the sloping roofs of the houses through a pipe. Rainwater falling on the rooftops would run down through a pipe and collect in the underground tankas.
(iv) The rainwater collected, is stored in the tankas providing drinking water till the next rainy season.
(v) When all other sources have dried up, these tankas were beneficial to beat the summer heat as they kept the rooms cool. The rainwater or palar pani, as commonly known in these parts, is considered the purest form of natural water.

Explanation:
Houses in the semi arid regions of Rajasthan have traditionally constructed tanks for storing drinking water. They are big and are a part of the well-developed rooftop rainwater harvesting system. The tanks are constructed inside the main house or the courtyard, and are connected to the sloping roofs of the houses through a pipe. The rain falling on the rooftop travels down and is stored in the tanks. The first spell of rain is not collected as this water cleans the roof and the pipes. The rainwater from the subsequent spells is collected. This water is used till the next rainy season, and is reliable source of water even after other sources have dried up. The tanks also help in cooling the houses as rooms built around them have generally low temperatures due to conduction.
