3. Global Water Use • In many places of the world, a staggering 30 to 40% of water or more goes unaccounted for due to water leakages in pipes and canals and illegal tapping. Source: UNESCO

4. Global Water Use • In 2000, more than 1 billion urban dwellers (nearly a third of all urban dwellers worldwide) lived in slums. A slum dweller may only have 5 to 10 litres per day at his or her disposal. A middle- or high-income household in the same city, however, may use some 50 to 150 litres per day, if not more.

6. Global Water Use • In order to ensure our basic needs, every individual needs 20 to 50 litres of water free from harmful contaminants each and every day. Source: UNESCO

7. Water Treatment • Access to safe water and sanitation is a fundamental requirement for basic human well-being

14. Access to Sanitation • 13% of the global population (0.9 billion people) used toilets or latrines where excreta were disposed of in situ. Source: WHO, UNEP

15. Access to Sanitation • Poor sanitation is linked to transmission of diseases such as cholera, diarrhoea, dysentery, hepatitis A, typhoid and polio. Source: WHO, UNEP

16. Access to Sanitation • 2.3 billion people still do not have basic sanitation facilities such as toilets or latrines. • Of these, 892 million still defecate in the open, for example in street gutters, behind bushes or into open bodies of water. Source: WHO, UNEP

17. Access to Sanitation • Inadequate sanitation is estimated to cause 280 000 diarrhoeal deaths annually and is a major factor in several neglected tropical diseases, including intestinal worms, schistosomiasis, and trachoma. Poor sanitation also contributes to malnutrition. Source: WHO, UNEP

18. Access to Sanitation • The UN suggests that each person needs 20-50 litres of safe freshwater a day to ensure their basic needs for drinking, cooking and cleaning. Source: WHO, UNEP

19. Access to Sanitation • More than one in six people worldwide - 894 million - don't have access to this amount of safe freshwater. Source: WHO, UNEP

20. Access to Sanitation • Globally, diarrhoea is the leading cause of illness and death, and 88 per cent of diarrhoeal deaths are due to a lack of access to sanitation facilities, together with inadequate availability of water for hygiene and unsafe drinking water. Source: WHO, UNEP

21. Access to Sanitation • Today 2.5 billion people, including almost one billion children, live without even basic sanitation. Every 20 seconds, a child dies as a result of poor sanitation. That's 1.5 million preventable deaths each year. Source: WHO, UNEP

30. Water and disease • Every day, 2 million tons of human waste are disposed of in water courses.

31. Water and disease • Cholera • diarrheal illness caused by infection of the intestine with the bacterium Vibrio cholerae. • Can be fatal if untreated

32. Water and disease • Cholera • Cryptosporidium • Dengue Fever • Guinea Worm Disease • Japanese Encephalitis • River Blindness • Schistosomiasis
