Indian Railways' Kankaria Coaching Depot becomes India's first water-neutral railway facility through advanced wastewater treatment.
The depot saves 1.60 lakh litres of water daily using phytoremediation plants and multi-stage purification systems.
Annual water conservation reaches 5.84 crore litres through treatment and reuse of coach washing and maintenance wastewater.
The eco-friendly initiative combines natural purification with technical filtration including carbon, sand and UV disinfection.
