The National Green Tribunal has issued notices to the Delhi Metro Rail Corporation, the Centre and the governments of Delhi, UP and Haryana on a petition accusing them of not putting in place rainwater harvesting systems at Metro stations in Delhi and the NCR.

There are 141 stations of which 130 are in Delhi, six in Noida, three stations in Gurgaon and two in Ghaziabad.

Environmentalist and petitioner Vikrant Kumar Tongad said: “If one uses the Delhi Jal Board’s yardstick, it’s clear that more than eight crore litres of water is being wasted every monsoon. Delhi and national capital region are going through a massive water crisis because of depletion of water table. We cannot afford such a waste.”

The tribunal will hear the matter on May 6.

The current water demand in Delhi is 1,025 million gallons per day, while the current supply stands at 850 MGD. The projected demand by 2012 is 1216 MGD.

“Rainwater harvesting in such a scenario cannot be ignored,” he said. He said both the Centre and the states has issued directions for rainwater harvesting but the Metro is yet to follow them.

“The DMRC has not installed rainwater harvesting systems at most stations on its network built during the first two phases. At some places where they have been installed, the systems are not working,” he said.

Submitting details obtained from the Delhi Jal Board, he said: The average rooftop area of one station is approximately 1,000 sqm.

There are about 106 stations where rooftop water harvesting facility can be installed. If rainwater harvesting system is installed properly on Metro stations, we can save 1.96 crore litres of water every year.

If we include elevated tracks for rainwater harvesting, we can save another 6.37 crore litres of water per year.Of the 141 stations, only 35 are underground.

The total length of the 10-metre-wide elevated track is approximately 126 km.
