Water Partners International

http://water.org/
Since 1990, the group has provided loans in developing countries to 54 communities who could - over time -afford to pay for their own water systems, but who had no access to credit. WPI donates 10 - 50% of the capital and maintenance costs, and lends the balance. Loan paybacks are used to fund new projects. Sponsors include individuals, foundations, and corporations such as bottled water company, Suntory.
