Ques 4 Discuss how rainwater harvesting in semi-arid regions of Rajasthan is carried out.
Solution: (i) Houses in the semi arid regions of Rajasthan have traditionally constructed tanks for storing drinking water. These 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 through a PVC pipe 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. These water tanks also help in cooling the houses as rooms built around them have generally low temperatures due to conduction.
