The Indian NGO [http://www.sulabhinternational.org/ Sulabh International] designed a [httphttps://www.sulabhinternationalircwash.org/contentsites/twodefault/files/323.1-pit-system 1299.pdf system] using pour flush toilets and twin pits for treatment of sanitation products. They have constructed over a million toilets in India. They further designed a system which converts the effluent into biogas. These technologies are now used by 10 million people in rural India. This contributed greatly to the increase in number of people using a toilet, from 27% to 59% in the last 5 years. They have also built public toilets in Afghanistan, Bhutan, Ghana, Ethiopia, Madagascar, Mozambique, Laos, and Cambodia. They are planning to start up Sulabh Sanitation centres in 50 more countries soon.
