Making every drop of water count


WATER is a vital element for human life. A person can survive for weeks without food but it is a different story if there is no water at all.

Water makes up about 70% of the Earth’s total surface but only one percent of this is fresh, liquid and usable. Most of the water is contained in the seas and oceans as salt water and as ice in glaciers and thus cannot be used directly by humans.
