Serving Human Needs-Nuclear Technology for clean drinking water

Clean drinking water
In the last century human population trebled, but fresh water consumption was six folded. Without efficient water resources development, management and use, half of the world’s population will be living in water stress region with competition from agricultural, industrial and domestic use. This is what World Water Vision unit of the World Water Council warns. Forty years ago human population was three billion; today it is over six billion. By 2050 it is expected to hit 9 billion. But the availability of water to meet the growing demands remains unchanged. Without water we cannot survive more than three days. As of now one out of five people on the planet earth does not have access to safe drinking water. Every year more than three million people die of waterborne diseases of
which two million are young children. A blue circle appeared to be mostly covered with water as visualized from outer space, the earth is in fact two third filled with water. However over 95% of earth’s water is salty or brackish. Of the remaining 3% about seventy five percent is locked in ice caps and glaciers. In fact the inventory of fresh/
clean water available for human use is less than one tenth of one percent of all water on the earth. No wonder the Ancient Mariner Lamented “ water, water every where nor any drop to drink.”
