Q. Describe how modern adaptations of traditional rainwater harvesting methods are being carried out to conserve and store water.
Ans. The traditional rainwater harvesting method is a big success in India. Therefore in many parts of rural and urban India, rooftop rainwater harvesting has been successfully adapted to store and conserve water. For example, in Gendathur, a remote backward village in Mysore, Karnataka, villagers have installed, in their household’s rooftop, rainwater-harvesting system to meet their water needs. Nearly 200 households have installed this system and the village has earned the rare distinction of being rich in rainwater. Rainwater harvesting is once again conserved through modern adaptation. Rainwater, running down from the roofs is not fed into drains. On the other hand, the rain water is piped into underground reservoirs.

Q. Find out more about any one traditional method of building dams and irrigation works.
Ans. In Meghalaya, an ingenious system of tapping stream and spring water is put up by using bamboo pipes to irrigate plantations of betel leaf or black pepper crops. The tribes of the Khasi and Jaintia hills have been using this from the last 200 years. About 20 litres of water enter the bamboo pipe system per minute and may travel almost a kilometre to finally reach the plants near its roots. Bamboo pipes are used to take water from perennial springs situated at the top of the hills to the plantations by using gravity. Reduced channel sections and diversion units are used at the last stage of water application.
Q. Find out other rainwater harvesting systems existing in and around your locality.
