Abstract:
The technology of two-pit pour flush toilet is economically affordable and culturally acceptable for most of the developing countries. Sulabh has implemented over 1.2 million such household toilets in India The conversion of bucket privies into Sulabh toilets has resulted in liberation of over 60,000 scavengers (most of whom are women), from manual cleaning of waste from privies. Those liberated have been provided vocational training in different trades for their socio-economic up gradation.
To provide sanitation in slums, at public places, markets etc., Sulabh is operating and maintaining over 6000 public toilets on “pay and use” basis in different parts of the country.
For unsewered areas for the safe, hygienic and affordable way of disposal of human wastes from public toilets, Sulabh generates biogas to be used for different purposes like cooking, lighting, and electricity generation. The effluent of biogas plant is reused after a simple and convenient method of treatment consisting of sedimentation followed by passing through sand column and activated carbon and finally with UV. Such effluent is colorless, odorless and pathogen free having BOD less than 10 mg/l - suitable for agriculture, horticulture or cleaning of floors of public toilets or discharge in any water body.
