Background
  - At any given moment almost half the developing world's people are sick from unsafe   water and sanitation.
  - Lack of water supply and sanitation robs millions of dignity, energy, and time.
  - Frequent disease is the main cause of poor growth and early death.
  - For a third of the world the real environment crisis is squalor, smells and disease on the   door step
  - Economies suffer as hygiene-related illness costs developing countries five billion   working days a year.
  - Sustainable development starts with people's hearts and dignity.
