I. Introduction
In the world that we live in we are moving towards an era where there will be no water left for consumption. Water resources throughout the world and especially in country like India, Pakistan and other Asian countries are very poorly managed. Half of the country are the victim of nature's fury. The waters of floods refuse to recede, and the other half of the same region is facing a severe drought. Unseasonal rainfall has left our country without any trace of consumable water. The people of the country are unaware when the water resources will dry up and how to prepare for an upcoming water crisis [2], [3], [8].
