Can rain water be harvested at 27 metro stations?:NGT to CGWA

The National Green Tribunal today directed the Central Ground Water Authority (CGWA) and Delhi Metro Rail Corporation to conduct a joint inspection of 27 stations to see if rain water harvesting systems (RWHS) can be set up there or not.
A bench, headed by NGT Chairperson Justice Swatanter Kumar, also asked the petitioner to join the inspection team after he submitted he had inspected the 27 stations and found they have space and it is possible to set up such systems there, contrary to the submission made by DMRC.
"The applicant (petitioner) submits he had inspected the 27 metro stations where according to DMRC the rain water harvesting system could not be installed. Upon inspection, he has found that they have space and it is possible to provide rain water harvesting system in those stations.

"Let CGWA and DMRC conduct a joint inspection along with the applicant and find out the correctness or otherwise of the inspection report prepared by the applicant," the bench said and listed the matter for further hearing on March 26.
"The team may also inspect the premises of Indian Oil Corporation for the purposes of providing rain water harvesting system," the tribunal said.
DMRC had on January 16 informed the Tribunal that it cannot install rain water harvesting systems in 27 of its stations due to lack of space but will set up the system in 17 others.
DMRC had assured NGT it is "planning to physically execute the work at the 17 stations progressively by March 2015".

The Tribunal was hearing a plea by Vikrant Tongad who is seeking installation of rain water harvesting systems in all metro stations, tracks and depots.
