As it prepares to transport more than a hundred thousand people between the Capital and its posh but water-starved neighbour Gurgaon each day, the Delhi Metro Rail Corporation is simultaneously doing its bit to tap every drop of rainwater. The DMRC has made extensive arrangements to catch rainwater on the entire stretch of the Central Secretariat-Gurgaon line that is scheduled to open by January 2010. To ensure there is no wastage of rainwater, recharge wells have been constructed at every 50 metres and two each at all the stations. "We are doing whatever we can to conserve energy and water. In the second phase of construction, provisions have been made for water harvesting along all lines and at all stations. We have made recharge wells in the viaduct and at the stations. On the stretch between Qutub Minar and Gurgaon border alone we have 228 recharge wells,' said Anuj Dayal, Chief Public Relations Officer of DMRC. These recharge wells are expected to mitigate the effects of rampant groundwater withdrawal in the area, which has led to a drastic depletion in water levels. The DMRC's energy conservation drive is also being extended to the construction of a "green building'. In collaboration with The Energy and Resources Institute (TERI), DMRC is constructing a multi-storey building that will be environment friendly. To be leased out "The building, which will be leased out for commercial purposes will be constructed at Sushant Lok. It will be energy efficient and have space for parking 500 cars,' said Mr. Dayal. The Central Secretariat-Gurgaon line that will pass through Race Course, AIIMS, Green Park, Haus Khas, Malviya Nagar, Saket and Qutub Minar before it enters Gurgaon is also expected to reduce surface traffic significantly. "The line will offer a comfortable and a quick travel option to commuters. It will also reduce the congestion and vehicular movement on the roads,' Mr. Dayal said. Spelling relief for commuters, DMRC will not only improve the condition of the existing roads and expand them, it will also construct a foot-over bridge near the DT City Centre. "As of now people have to dash across the road, but we have decided to provide a foot-over bridge near the station planned at the DT City Centre. There will be provisions to help people cross the roads at each station,' said Mr. Dayal. Referring to the pace of work on the line Mr. Dayal said: "The progress of work is good and we will comfortably meet the deadlines of various stations. At the stretch between Qutub Minar and Gurgaon border, 58 per cent civil work is already complete.' The 7.3 km stretch between Delhi-Haryana Border and Sushant Lok in Gurgaon that will open in January 2010 will have five stations, while there will be four stations on the 8 km Qutub Minar-Gurgaon border stretch that will be completed by May 2009.
