INTRODUCTION
Water the elixir of life feeds the planets ecosystem, flows through our bodies and buildings connects humans through a source of life.
Even this 1%, which is renewed by hydrological cycle is put to severe stress due to overuse and pollution. The world is today facing a serious overall scarcity of water on one hand and on the other hand the available surface and ground water is becoming unsafe for consumption due to several agricultural, domestic and industrial pollution.
70% of our planets surface is water, yet only 2.5% is fresh water. The remaining 97.5% is salt water, out of the 2.5%, 1% alone is available for human consumption.
WHAT CAUSES & TRIGGERS THE WATER CRISIS
Water crisis on earth has been caused by
♦ HIGH POPULATION GROWTH
♦ RAPID URBANIZATION
♦ EVER INCREASING DEMAND FOR COMPETING USES LIKE
More than one billion people have no access to safe drinking water. It is estimated that by 2025, more than half of the World’s Population will be facing water vulnerability. India is one among the countries which face a severe water stress. This quantitative and qualitative water stress is known as water crisis.
