Central Railway (Mumbai) has become the first division of Indian Railways to replicate the concept of Japanese Railways’ water-saving model. An experiment of installing a mini water treatment device inside trains to recycle water from wash basins and dripping AC unit water for flush tanks has been successful, and the idea saves and limits use of water in tanks of trains on the move.

“As of now, the idea is just a proof of concept. The solutions proposed, even though effective, require proper design philosophy changes during coach manufacturing and periodic overhaul at workshops for aesthetics, ease of maintenance, and optimised space utilisation on large-scale implementation,” said Divisional Railway Manager (DRM) Rajneesh Goyal, the brainchild behind the idea.
