The extensive Delhi zone of the Indian Railways, it seems, is still dependent on tubewells for its whooping water demands running into lakhs of litres and has failed to set up Rain Water Harvesting Systems (RWHS) at its stations and colonies.

In an RTI reply, the Railways has stated that 14,45,500 litres of water was consumed daily in its eight colonies in Delhi for domestic purposes and also for cleaning trains. All this water was drawn from tubewells .
