Water is an invaluable natural resource. Today, there is a severe crisis of water all over the world. Constant rise in population, demand to grow more food grains and cash crops for rising population, increasing urbanization, changing lifestyle industrialization, etc. are some of the major causes that has led to water crisis.

The current situation of water supply and the inequality, as well as inefficiency in its distribution, poses severe problems for livelihood of human beings and economic development. Water crisis is a very serious problem in arid regions of Western Rajasthan and the interior area of southern peninsular plateau. We need pure potable water for our survival. But, the quality of water has deteriorated at many places. This results in several water-borne diseases.

Although the government puts hard efforts to increases the facility of potable water, there exists a large difference between the demand of water and its supply. About 8% of Indian towns face severe shortage of drinking water. About 50% of our village still does not get pure drinking water. Same is the case for water crisis in irrigation. Although, we have made very good progress in our irrigational facilities as 2/3^rd area under agriculture still depends on rainwater.
