Global: It is estimated that more than one billion people – about one in eight –do not have access to improved water supply whereas 2.6 billion people lack access to adequate sanitation globally. Nearly half the people in the developing world do not have proper toilet facilities. India is one of the developing countries facing serious drinking water problems and lack of toilet facilities. Diarrhoea claims the lives of 2 million children around the world every year as a result of drinking unsafe water and living in unhygienic conditions. Unsafe drinking water, along with poor sanitation and hygiene are the main contributors to an estimated total 4 billion cases of diarrhoea each year in the world.
