Answer
One of the traditional methods of irrigation include Well Irrigation.
A well is a small hole dug in the surface of the earth to obtain water from the water table for irrigation and other purposes. Wells are usually of two types: Lined wells (manmade), and Unlined wells (formed by different natural phenomena).
Well irrigation is a cheap, simple and dependable source of irrigation. It is practised in areas where plenty of groundwater is available and the depth of the water table does not exceed 15m.
