Bio-digester technology that converts sewage waste into water and gas.
The technology has been developed by Defence Research and Development Organization (DRDO) and is suitable for Rural and Semi-Urban areas. 
The Bio Digester Technology is a clean technology that does not pollute ground water and the effluent in water, CO2 and methane gas.  The effluent water is enriched with minerals that is odorless, colourless and free of pathogens and can be used for gardening or recycled for flushing.
