    PASSENGERS travelling in long-distance trains will soon get respite from the stench of toilets with railways set to replace them with odourless bio-toilets.

    With a view to provide more hygienic conditions, the railways would manufacture 2,500 bio-toilets in the upcoming fiscal.

    “There is an urgent need to replace the conventional open-discharge toilets with green toilets with a view to having cleaner, hygienic and safer railway ecosystem,” said Dinesh Trivedi, railway minister, while presenting the rail budget on Wednesday.

    Railways has joined hands with Defence Research and Development Organisation (DRDO) for development of bio-toilets.

    “The DRDO developed bio-toilets are currently under extended trial to test their efficacy and suitability,” Trivedi added.

    Unlike traditional toilets in trains where the waste is discharged on tracks, the new system will treat the same inside a tank with the help of a bacterium, which will convert it into harmless gas and water.

    This will not only improve the environment but also help in preventing corrosion of rail tracks, said a senior railway ministry official.

    Corrosion from night soil being discharged from toilets on tracks costs Rs 350 crore annually.

    Estimated to cost about Rs 1 lakh per bio-toilet, these new age toilets will be manufactured at Kapurthala coach factory and fitted in long-route trains.

    The eco-toilets will not only improve the environment but also help in preventing corrosion of rail tracks

    While about 50 bio-toilets will be fitted in Linke Holfmann Bush (LHB) coaches, the rest will be used in conventional coaches.

    The bio-toilets are already operational in some coaches as part of a pilot project. Some modifications are being made during the trial and now the new technology will be extended to as many trains, said the official.

    The anaerobic bacteria inside the toilets consume waste material and convert it into water and gas in the bio-toilet system. The water passing through chlorine tank is discharged as clean water and the gas generated evaporates into the atmosphere.
