Labelled diagram of Traditional Water Harvesting System
Labelled diagram of Traditional Water Harvesting System: Water storage is an old concept in India. Khadin, tanks and nadisin Rajasthan, Bhandara and tal in Maharashtra, Bandhi in MP and Uttar Pradesh, Ahar and Pines in Bihar, Kulh in Himachal Pradesh, Lakes and Eris in Kandy belt in Jammu region, Surangam in Kerala and Katta in Karnataka are some of the ancient reservoirs., including waterways, structures are still in use today. Water harvesting techniques are highly local and the benefits are also local. Giving people over their local water resources ensures that mismanagement and overexploitation of these resources is reduced/eliminated. In largely flat terrain, water storage structures are primarily crescent shaped earthen embankments or low, upright concrete-underbelly “check dams” built over seasonal flood plains. Monsoon rains fill the ponds behind the structures. Only the largest structures have water throughout the year, most are dry six months or less after the monsoon. However their main purpose is not to retain surface water but to recharge groundwater. There are many benefits of water stored in soil. It does not evaporate, but diffuses to replenish wells and provide moisture for plants over a wide area. In addition, it does not provide a breeding ground for mosquitoes like ponds. Ground water is also relatively protected from contamination from human and animal waste.
