Rob Kramer, chairman of the Global Water Trust, likes to tell an apocryphal story of a trunk line extension project in remote Africa, where pipe was run to within a quarter mile of a village in need—but the pipe kept getting vandalized. “Turns out,” he says, “the four hours every other day that the women spent hiking out to gather water was the only time they got away from their husbands. They cherished this privacy, so they kept sabotaging the pipe.”
