Water is essential for sustaining life and at the same time, it is an important component for almost all developmental plans. Obviously the schemes for development of water resources for beneficial use of the society have been taken up since the time immemorial. Considerable progress has been made in respect of water resources development in India after independence through various Plans and such developments have helped in almost five fold increase in creation of irrigation potential. Total created irrigation potential at pre-Plan period was about 22.6 million hectares (Mha) which at present is about 108.2 Mha. There has also been appreciable development in the areas of drinking water supply and other uses. However, growing population, urbanization and industrialization has led to considerable increase in demand of water for various purposes e.g., irrigation, domestic needs, industrial requirements etc.
