Uttarakhand flash floods: Rescuers boring wider hole in Tapovan tunnel to reach 30 trapped inside
India TodayRescuers on Saturday began boring a wider and deeper hole into the tunnel at the flood-ravaged Tapovan-Vishnugad hydel project in an attempt to reach the over 30 people trapped inside for nearly a week. “The Silt Flushing Tunnel was punctured on Friday night itself by drilling a 75mm-diameter hole into it but now it is being widened to 300 mm so that a camera and a water flushing pipe could be inserted into the tunnel where the trapped are possibly located,” news agency PTI quoted General Manager of the NTPC project R P Ahirwal as saying. Rescuers said they were still hopeful of finding survivors, notwithstanding the numerous challenges like the muck and the water from Dhauli Ganga constantly flowing into the tunnels.The river had deviated from its path after the flash floods that have left 38 people dead and 166 missing, reported PTI. Talking about the biggest challenge being faced by the rescue team, the NTPC official said, "The rescue personnel are going to the tunnel where the men are likely to be trapped via HCC Adit where muck is constantly coming down from the NTPC barrage and its desilting basin to hamper the rescue efforts "The water of Dhauli Ganga too is coming into our tunnels through the desilting basin as it has tilted to the left after the avalanche."
