"Till such time better designs come up, implementation of the two designs for individual household toilets and community toilets for disposal of human waste developed by Sulabh will realise the wishes of Gates to a large extent," the founder of Sulabh International Bindeshwar Pathak said.
He was referring to Gates' desire of employing on a wide scale a low-cost toilet model to provide a solution to the problem of defecation in the open resorted to by millions in India and other developing countries in Asia, Africa and Latin America.
Pathak said Sulabh toilets used just a litre of water for flushing rather than 10 litres needed in conventional toilets.
He said Sulabh designs deserved to be adopted on a much wider scale because these satisfied the important criteria of a technology design which is culturally acceptable and economically affordable.
The designs have already been accepted many countries of Africa and in Afghanistan, he pointed out.
He said Sulabh maintained nearly 8,000 public toilets for community use. Some of them were attached to human excreta-based biogas plant and the Sulabh Effluent Technology device.
The device treated effluents emanating from public toilets and make them colourless, odourless and pathogen-free, he said.
