discuss how rainwater harvesting in semi arid regions of rajasthan is carried out.
Answers
(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.
Answer:
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 a 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.
