Well irrigation is popular in areas where sufficient sweet ground water is available. These areas include a large part of the Great Northern Plain, the deltaic regions of the Mahanadi, the Godavari, the Krishna and the Cauvery, parts of the Narmada and the Tapi valleys and the weathered layers of the Deccan Trap and crystalline rocks and the sedimentary zones of the Peninsula.
However, the greater part of the Penisnular India is not suitable for well irrigation due to rocky structure, uneven surface and lack of underground water. Large dry tracts of Rajasthan, the adjoining parts of Punjab, Haryana, and Gujarat and some parts of Uttar Pradesh have brackish ground water which is not fit for irrigation and human consumption and hence unsuitable for well irrigation.
There were about 5 million wells in 1950-51 and their number has now increased to about 12 million. Well irrigation accounts for more than 60 per cent of the net irrigated area in the country against 29.2 per cent of canal and only 4.6 per cent of tank irrigation. It accounted 59.78 lakh hectares in 1950-51 which rose to about 332-77 lakh hectares in 2000-01 thereby registering more than fivefold increase in well irrigation.
