Human faces a critical challenge in obtaining clean drinking water especially in developing and under developed countries.

Fast deterioration of groundwater sources of drinking water badly influence the availability of clean water and drive people to use more bottled water as a " reliable quality water supply"

The water-scarce areas are fast growing that will influence lives of approx. 6 billion at 2050. Bottled water supply is one of the available and relatively low-cost interim solutions  to the problem.
