Water is our life line. One cannot imagine what would happen to mankind without water. If there is no water there would be no life on earth. The only living being that does not understand the importance of water is human, especially the industrialized countries.
An average person can spend weeks without eating food but he or she cannot spend 2-3 days without drinking water. It not only quenches your thirst but also plays a vital role in metabolism of the body by helping in digestion and excretion.
Pure water is colorless, odorless and tasteless, it is chemically made of two components that is hydrogen and oxygen. Because water is a universal solvent, it dissolves almost everything which comes in contact with it. Pure and safe water is hard to get nowadays as there is a rapid increase in water pollution.
