KONKAN RAILWAY GOES GREEN
Adds more Bio-Toilets at its Stations
As its continued efforts towards promoting green solutions and providing eco-friendly transport solutions, Konkan Railway has taken a major step towards bio-degradation of night soil (human mull) by installing Bio-Toilets on its route. Konkan Railway is the first railway in the country to have Bio-Toilets on railway station platforms. The first Bio-toilet was constructed at Kankavali station by Konkan Railway on its route, followed by Chiplun station. Now, it is set to add six more stations to this list. The stations where the Bio-toilets are going to be constructed are Sawantwadi, Madgaon, Thivim, Karmali, Karwar, and Byndoor. Apart from this, some trains running on the route are also fitted with Bio-toilets to prevent open disposal of mull on the railway tracks.
The technology while allowing eco-friendly and faster way of human waste disposal, is also economic. It is based on Bio-Digester technology developed by DRDO (Defence Research & Development Organization). The technology is 100% maintenance-free and allows complete elimination of pathogens without requiring the night soil to be disposed through sewage line and septic tank. Since it does not require septic tanks and sewage lines, the Bio-Toilets can be installed much faster than a regular RCC toilet. While the latter requires a minimum of 2 months for construction, the Bio-Toilet can be installed in just a couple of days. The saving in cost factor is also 70% less compared to a regular RCC toilet. While a conventional toilet would cost about Rs.1 lakh, the Bio-Toilet can be erected in only about Rupees Thirty Thousand.
The Bio-Digester is charged initially with anaerobic bacterial inoculums and no further charging is required if the Bio-Toilet is in regular use. The bio-degradation of the night soil leads to generation of bio-gas which can be utilized for cooking purpose. The clean, odour-less water that is extracted after bio-degradation can be used for irrigation of gardens etc.
More stations will be covered on the route in a phased manner.
