Find out about the traditional systems of water harvesting/management in your region.
There are many traditional methods of water harvesting or management like khadin system, ponds, tals, canals, kohli tanks, rain water harvesting, saza kuva, and wells have been dug for the drinking water. Many water reservoirs are made by the government for the drinking water for humans as well as animals.
Water has been harvested in India since antiquity for the water management and for saving the water in drought conditions. By harvesting the rain drops with the direct connection from the rooftop where water is collected to the tanks where water is stored built in the courtyard, this is rain water harvesting system; khadin is also known as dhora and used to harvest surface runoff water for agriculture; ponds are the large water harvesting system for the groundwater recharge, infiltration etc; kohli tanks are the main water harvesting system or ancient harvesting system, it is cylindrical shaped formed underground and when rain comes it fills with water and keep it cool or fresh rainwater in it; kuva, wells, canals have been made by the artificial methods for the water harvesting or management.
As in the chapter showing the khadin, tanks and nadis as the traditional system of rain water management system in Rajasthan, also known as dhor; Bandharas and tals in Maharashtra; bundhis in Madhya Pradesh and Uttar Pradesh; Surangams in Kerala; and Kattas in Karnataka are used as ancient water harvesting systems. In largely level terrain, the water harvesting system is composed of earthen embankment or low, check dams are built across seasonally flooded gullies. Monsoon rain filled behind the structures only the large structure will hold the water for the long- range. The main purpose of the water management is not only to hold the water of the surface level but also holds the ground water level as well. Groundwater do not evaporate and spreads to fill the wells and provides moisture the earth and the soil respectively.
