I have seen such solutions in the Millennium Villages in rural Africa, a project in which my colleagues and I are working with poor communities, governments, and businesses to find practical solutions to the challenges of extreme rural poverty. In Senegal, for example, a world-leading pipe manufacturer, JM Eagle, donated more than 100 kilometers of piping to enable an impoverished community to join forces with the government water agency PEPAM to bring safe water to tens of thousands of people.
