Q3 Answer the following questions in about 120 words.

(ii) Describe how modern adaptations of traditional rainwater harvesting methods are being carried out to conserve and store water.Ans: 1. In the semi arid and arid regions of rajasthan, particularly in Bikaner , phalodi amd barmer, almost all the houses traditionally had underground tanks or tankas for storing drinking water. The takes could be as large as a big room. The tankas were part of the well developed rooftop rainwater harvesting system and were built inside the main houses through a pipe. Rain falling on the rooftops would travel down the pipe and was stored in these underground tankas. The first spell of rain was usually not collected as this would clean the roofs and the pipes. The rainwater from the subsequent showers was the collected. The rainwater can be stored in the tankas till the next rainfall making it an extremely reliable sources of drinking water when all other sources are dried up particularly summer.
2. fortunately in many parts of rural and urban india, rooftop rainwater harvesting is being successfully adapted to store and conserve water. In gendathur a remote backward village in mystore Karnataka villagers have installed in their households rooftop rainwater harvesting system to meet their water needs. Nearly 200 household have installed this system and the village has earned the rare distinction of being rich in rainwater. Rainwater harvesting is once again being conserved through modern adaption. Rainwater running down from the roofs is not fed into drains. Instead it is piped into underground reservoirs.
