<\/p>\n10 years ago, the greatest number of manual scavengers were employed to clear the railway tracks of excrement from the train toilets.\u00a0 Targets were set to convert toilets on carriages gradually over 15 years until 2025.\u00a0It seemed like it would never happen!\u00a0But steady progress has been made.\u00a0The new design for train toilets is to empty into a kind of septic tank rather than directly onto the tracks. Waste water overflows from the tank and pours onto the gravel of the tracks in a steady stream using the railway tracks rather like a nation-sized trickle filter.\u00a0When the tanks are filled, they are emptied (presumably by machines) at maintenance depots.\u00a0 Already the railway tracks are cleaner and train station platforms are more pleasant places to wait. And, the job of the manual scavengers employed on India\u2019s Railways is much improved.<\/p>\n
In 2016, the Government of India gave environmental sanitation much importance through the Swachh Bharat Abhiyan (clean India initiative). Prior to that 50% of people in India were defaecating in the open. The programme aimed for India to be \u2018open defaecation free\u2019 by 2nd October 2019. \u00a0That didn\u2019t happen but the number of households with access to toilets has increased by an impressive 30%.<\/p>\n
To some extent, the programme did promote \u2018sanitary latrine\u2019 technologies that \u2018safely confine human faeces and eliminates the need of human handling before it is fully decomposed\u2019. However, in many places, the toilets being constructed were of the single pit latrine type, which in all likelihood will require the services of manual scavengers to empty.<\/p>\n
One dignified sanitation option with lots of potential is \u2018simplified sewerage\u2019: i.e. household toilets \u2013 linked to simplified (piped) sewerage \u2013 treated in a large settlement tank \u2013 waste water discharged into a constructed wetland.\u00a0 A system like this would be cheap to install, easy to maintain and remove the need for the manual handling of faeces or sludge.\u00a0 This technology is widely used in other countries (especially in South America) and has proved to be highly effective.<\/p>\n
