Question

Discuss how rainwater harvesting in the semi-arid region of Rajasthan is carried out.

Answer 1

Hint: Rainwater harvesting is that the collection and storage of rain, instead of allowing it to escape. Rainwater is collected from roofs of houses and redirected to a tank.

Complete answer:
Rain water harvesting in semi-arid regions of Rajasthan is administered within the following ways:-
(i) In Rajasthan semi-arid regions, every house is having underground tanks to store the water for drinking purposes.
(ii) These tanks are large and deep which were built inside most houses or the courtyard.
(iii) They were linked to the sloping roofs of the homes through a pipe. Rainwater falling on the rooftops would run down through a pipe and collect within the underground tankas.
(iv) The rainwater collected, is stored within the tanks providing beverage till subsequent season .
(v) When all other sources have dried up, these tanks were beneficial to fight against the summer heat as they kept the rooms cool. The rainwater or palar pani, as commonly known in these parts, is taken into account the purest sort of natural water.
(VI) Paar is a common water harvesting practice in the western Rajasthan region. It is a standard place where the rainwater flows from the agar and within the process percolates into the sandy soil. In order to access the rajani pani which is percolated water, kuis or beris are dug within the agor which is a storage area.

Note: In semi arid regions of Rajasthan rainwater harvesting helps utilities reduce peak demands during summer months, saving treated water for more important and appropriate water uses.
