Although over 70% surface area of world is covered by water, only 2.5% of total quantity is fresh water, which can be used by plants, animals and humans. However, nearly 90% of this freshwater is not readily available, because it is centred in icecaps of the Antarctic. Only 0.26% of the water on this world is available for humans and other organisms, this is about 93.00 cubic kilometres. Only 0.014% of this water can be used for drinking water production, as most of it is stored in clouds or in the ground.
Population growth reduces availability of fresh water on per capita basis. In 1989 there was some 9,000 cubic metres of freshwater per person available for human use. By 2000, this had dropped to 7,800 cubic metres and it is expected to plummet to 5,100 cubic metres per person by 2025, when the global population is projected to reach 8 billion.
Judicious usage of every resource is now a necessity. For our future generations, we have to re-design our usage processes and patterns for ‘Sustainable Usage’ of resources.
IEC products are useful for judicious water usage. It reduces the requirements and improves utilization of water. The chemistry of IEC products action is depicted as below:
