Dr. Bindeshwar Pathak
To address this situation, Dr. Bindeshwar Pathak, a social worker, environmentalist and Founder of the Sulabh International Social Service Organisation, developed the technology of a twin-pit, pour-flush toilet known as Sulabh Shauchalaya, of which over one million have been constructed. This environment friendly technology provides on-site disposal with no smell and soil pollution, and it conserves water.
Through this development, there has been a massive change in the attitude and behaviour of people towards sanitation. Indians now readily pay charges in 6,000 Sulabh public toilets.
Biogas production from human excreta in 120 public toilets and its various uses, e.g. lighting, cooking, etc and the use of effluent as rich fertilizer is one of his hallmark contributions. To the biogas plant is attached the Sulabh effluent as rich fertilizer is one of his hallmark contributions. To the biogas plant is attached the Sulabh effluent treatment plant, whereby water discharged is made colourless, odourless and pathogen free, fit for reuse in agriculture, pisciculture, or cleaning of public toilet or discharge into any water-body, promoting a better and healthier environment. In both the technologies, there is production of organic nutrient-rich fertilizer and reuse and recycling of waste matter.
In 1996, Pathak’s Sulabh Sanitation System was recognized as Global Urban Best Practice by UN-Habitat at
