Indian Railways has provided more than 2 lakes bio-toilets in its coaches till August 2019. The Bio-toilet project is very much aligned with ‘Swachh Bharat Mission’




Technology For Bio-Toilets

The technology for Bio-toilets has been innovated, designed and is ‘Made in India’. The environment-friendly technology has been developed jointly by Indian Railways (IR) and Defence Research and Development Organization (DRDO) for railway passenger coaches through an MoU.


  • Bio -Toilets technology is first of its kind being used by any railroad in the world for On-board accelerated digestion of human waste.
  • These bio-toilets are fitted underneath the lavatories and the human waste discharged into them is acted upon by a colony of anaerobic bacteria that convert human waste mainly into water and small amount of bio-gases.
  • The gases escape into atmosphere and waste water is discharged after chlorination onto the track.
