CR Takes a Leap Forward in Providing Eco-friendly Bio -Toilets on More Number of Trains


In tune with the eco-friendly / green initiatives of South Central Railway and after successful trial of 48 Bio-Toilets fitted to the 17 Coaches being run o­n Hyderabad-Mumbai Hussain Sagar Express and Kacheguda-Bangalore Express, South Central Railway is expanding the same to other trains also by procuring 200 Bio-Toilets with in few months.
 Bio-Toilet was developed jointly by Railway Research and Standard Organisation (RDSO) and Defence Research Development Establishment (DRDE) foruse in Indian Railways and the same is under trial in many of the Zonal Railways. South Central Railway took a lead in the trial and put the Bio-Toilets into regular use in the trainsas mentioned above towards strengthening cleanliness in Railway premises in an eco-friendly manner.
 The conventional toilets in the trains, by allowing night soil to fall o­n the track, cause unhygienic conditions and corrosion to track and coach fittings endangering the safety. Passengers use toilets while trains are at platforms and the track get scattered with human excreta creating unpleasant situation for passenger o­n the platforms.
 Maintaining the cleanliness at railway stations, especially the tracks at stations, is found to be a challenging task for railways in the face of ban o­n the use of Safaiwalas and absence of RCC Apron below the track atsome stations. Track maintenance staff also have to face difficult situation while o­n duty. But, with the advent of Bio-Toilet, Railways has foundan answer to this vexatious problem which is mainly due to letting the night soil from train toilets to fall o­n the track.
 With simple design, less maintenance and easier RETRO fitment o­n existing coaches, the environmental friendly Bio-Toilet will ensure zero discharge of night soil on the ground. This arrangement will be of great help in adding to the tidy environment and hygienic conditions of the railway stations and track en-route. Thus, Bio-Toilets are not o­nly environment friendly but also will contribute to preventing damage to track / coachfittings and improving the aesthetics of railway stations.

The Bio-Toilet, which has six compartments, uses Inoculums (Bacteria) to decompose the night soil. The night soil from commode enters in to the Bio-Tank, where the inoculums are stored, get decomposed by the bacteria  and the decomposed human soil will next enter into Chlorine Tank and to get purified.  Finally the out put will be just water and gas. Bio-Toilets with provision to replenish Inoculums and Chlorine will be easy to maintain. This toilet will get chocked and go out of order if passengers dump bottles, plastic carry bags, cups, napkins etc  into the it via commode. It will cause choking of the toilet making it un-usable and becomes difficult for the maintenance staff to clean the same. Hence, Passengers are advised not to dump any garbage / litter items in Bio-Toilet units.
