CHENNAI: Metro rail has started issuing notices to houses situated near the proposed 24 km underground stretch to close their bore wells, as it prepares to undertake drilling for tunnels from March 2012, a metro rail spokesman said. The spokesman said since the boring of 6.6 metre diameter twin tunnels are to be taken up from March 2012 on Corridor 1 between Washermenpet - Saidapet ramp and on Corridor 2 between Central and Tirumangalam, notices have been issued to the residential areas which fall under the alignment.“It is necessary to close existing bore and open wells within 16.5 m on both sides from the centre of the alignment for tunnelling.” “As per Metro Rail Construction Act 1978, CMRL has started issuing notices to the houses in the alignment for closure of bore wells and completed works in certain areas, the spokesman said.“Alternate bore wells will be provided close to the houses or in case alternate borewell is not required a compensation of `1 lakh will be provided according to the choice of the owner,” he said. “Closure of bore wells will be carried out only after making alternate water supply arrangements to the affected houses. Tunnelling will not lead to any environmental problems nor have any impact on ground water in the locality,” the spokesman said. Metro rail also clarified that CMRL will take precautionary steps to ensure safety of the building and structures. The completion of the first phase, involving 21 km of elevated track, is expected by end-2013 while the 24 route-km underground stretch is scheduled to be finished by mid-2015.
