The Sanitation Crisis Only 31% use improved sanitation (2008) In rural India 21% use improved sanitation facilities (2008) 638 million people defecate in the open; over 50%. The Water Crisis 88% have access to drinking water from improved sources (2008) Only 25% have drinking water on their premise Women, who have to collect the drinking water, are vulnerable to a number of unsafe practices 67% of Indian households do not treat their drinking water INDIA Population: 1.2 billion Source: UNICEF
