Water is in fact, one of the five basic elements of nature and a basic necessity of life. Can we imagine a life without water? The answer must be a big “No”. The Governments are spending billions of dollars to locate water on other planets. It has become so scarce in some countries that they are charging for even small quantities of water. We need not wonder if there is going to be a world war for water in a few years. 3/4th of our planet contains water. Of this 97% of water is present in oceans and seas which cannot be used for drinking or for other domestic purposes. 2% of water is in the form of glaciers. Henceforth, only 1% water is in human usable form and there is a real requirement to save money on water.
