Sulabh created a low-cost toilet technology that not only helped maintain sanitation but also restored the dignity of millions of “scavengers”, the cleaners of human excreta who are traditionally untouchables. The West’s toilet technology, composed of sewage and septic tanks, was unaffordable for India’s teeming millions. Pathak’s technology relies on two simple pits and sealed covers. While one pit is in use, the other is left to decompose, forming a fertilizer that can be used in agricultural fields. Equally important, human waste no longer requires manual cleansing.
