The NGT [National Green Tribunal] has order Delhi Chief Secretary to schedule a meeting with all Deputy Commissioners to install rainwater harvesting systems in both residential and commercial buildings that cover an area up to 100 square meters or more.
The bench headed by NGT Chairperson Justice Adarsh Kumar Goel also directed all Deputy Commissioners to ensure the installation of rainwater harvesting systems properly in all buildings falling under their jurisdiction. NGT also said that in case the measures for the same has already taken then the meeting can be hold to discuss the proper and timely installation of this water saving technique. The green tribunal also added that post installation, the authorities must check for proper working of the mechanism and an effective monitoring mechanism is likely to be fixed.
The chief secretary was also directed to file an affidavit on the same issue within two months. On the other hand, Delhi Jal Board informed NGT that inspection is already been carried out for the installation of Rainwater harvesting at multiple locations and the places left for the same will be inspected soon.
The directives from the National Green Tribunal [NGT] came on a plea made by environmentalist Vikrant Kumar Tongad in the year 2014 , who sought directions to DMRC for installation of proper rainwater harvesting system in all existing, proposed and under-construction metro stations, tracks and depots.
The green tribunal, however, widens area and asked to incorporate hospitals, hotels and malls in the process of installing the Rainwater harvesting system.
