3. Safe Drinking Water Scenario

3.1 Background

Water, one of nature's most important gifts to mankind, is an essential element to good health. Though 70% of the earth's geographical area is covered by water, only 1% of it is potable, the rest being unsafe for consumption. Natural water sources, especially rivers, annals', ponds, wells, etc. are being exploited, mistreated and contaminated, making drinking from them unsafe. Unlike in the inland areas, in delta regions, an adequate quantity of water is made available for drinking purposes, often through irrigation canals and sometimes through subsurface sources. Over the years, however, the canal water has become highly polluted with presence of physical and chemical impurities, as well as harmful bacteria.

Water purification is the process of removing contaminants from a raw water source. The objective is to produce water for a specific purpose with a treatment profile designed to limit the inclusion of specific materials; most water is purified for human consumption (drinking water). Water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacology, chemical and industrial applications. Methods include, but are not limited to: ultraviolet light, filtration, water softening, reverse osmosis, ultra filtration, molecular stripping, deionization, and carbon treatment.

3.2 Global Drinking Water Scenario

The Water Health Organisation (WHO) reported that more than 1.1 billion people across the globe draw water from unsafe sources, causing widely spread diseases like diarrhoea. Nearly 70% and 80% of these people live in rural areas. It is difficult to control the quality of drinking water even in the most developed countries, and small community water supplies frequently fail on basic microbiological quality and other physical impurities, like, suspended solids in case of surface water, and total dissolved solids (TDS) mostly in ground water. The lack of clean drinking water for some 1.1 billion people in this world has dramatic consequences: approximately 4 billion cases of diarrhoea are reported annually, of which 2.5 million ends in death.
