Railways have taken up the work of installing rain water harvesting facilities wherever possible from techno-economic considerations i.e. intensity of rain fall, level of water table, soil type, salinity of ground water etc.

Railways has already installed rain water harvesting facilities at 2060 locations and for 130 more locations for installation of rain water harvesting facilities have been approved. From techno-economic consideration it was not found feasible to install rain water harvesting facilities at terminals and suburban stations of Mumbai.
