In a first of its kind,bio-toilets are making their way into train coaches. Following an innovation by the Railways in collaboration with the Defence Research and Development Establishment (DRDE),a revolutionary design of bio-toilets are being installed in trains.
The new toilet has a collection tank provided with anaerobic bacteria to decompose fecal matter and only a colourless,odourless liquid that does not pollute the environment is released from the tank. The tank has seven chambers and by the time the excreta traverses through these chambers and reaches the exit,it is fully decomposed,said officials.
The resultant water passes through a chlorinated chamber to control its pH level and microbe content. The problem of toilets getting choked has also been taken care of in this design. The tank inlet has been provided with a valve which can be manually operated to clear the choke, said Ashwani Lohani,Divisional Railway Manager,Northern Railway. This design of toilets will not only replace stinking toilets but also do away with manual scavenging on trains and add to the life span of railway tracks.
To begin with,the first rake fitted with such anaerobic bio-toilets will be put on the Indore Intercity Express running between Hazrat Nizamuddin and Indore from April 13. Such bio-toilets have also been installed in eight other trains running across the country. Officials said that the cost of one toilet is about Rs 1 lakh and the Railways now plans to install 3,000 more such toilets in 750 coaches spread across the country.
