Saha sets village women up in Northern Ghana with water treatment businesses that provide readily available clean water at a price that all can afford.

Kate, a former MIT aerospace engineer, became obsessed with the problem of getting clean water to people in remote villages. She soon realized that the answer was not whiz-bang technology, but a simple, foolproof system of distribution. Her persistence paid off: 75% of the homes in a Saha village have clean water covering 50,000+ people a day.
