Abstract: Inadequate sewage systems and the lack of toilets in India have created a major public health and environmental crisis. One of the finest examples is represented by the Indian rivers.The rivers of the Indian subcontinent flow clean and clear from the Himalaya, then become little more than sewers as they run through major cities in the plains. New Delhi’s Yamuna River receives roughly half of the largely untreated sewage of a metropolis of 17 million. The Ganges, too, is fouled by raw sewage from tens of millions of people as it flows 1,500 miles from the western Himalaya to the Bay of Bengal. The ultimate solution to this problemis not to invest in western-style flush toilets and centralized sewage systems but rather to develop toilets and decentralized waste-treatment technologies that use far less water and convert human waste into useful (or at least benign) components.Most importantly, they must protect water sources — rivers, streams, and groundwater — from the water-borne diseases so endemic in the developing world. This study brings into highlight the existing products and technologies (worldwide) based upon resource orientated sanitation approaches and a business model for affordable and sustainable sanitation in rural Indian villages. To conclude,sanitation approaches must be resource minded, not waste minded.
