Technology.am (Aug. 26, 2009) — Indian sanitation expert Bindeshwar Pathak has found a way that can save water, and lives, in developing countries.
Pathak was awarded this year’s Stockholm Water Prize for his revolutionary toilet at the World Water Week conference held in Stockholm.
To lower the risk to human health, he developed a twin-pit, pour-flush toilet known as the Sulabh, that uses two tanks to store waste matter with no smell or soil pollution, pending recycling as fertiliser.
It requires only 1.0 to 1.5 liters to flush instead of 10 liters,” he said. “It saves trillions of litres of water each year.”
For four decades, his Sulabh Sanitation Movement has equipped more than 1.2 million households with eco-friendly toilets and installed 7,500 public lavatories across India.
The poorest families pay 15 dollars (10 euros) whereas richer families can be asked to pay up to 1,000 dollars.
