‘Silted pores on brick sewer flooded metro station’
Times of India | 23 July 2024
Kolkata: Metro Railway said on Monday that it has investigated and found out the actual reasons behind the flooding at Park Street metro station on May 28, when Cyclone Remal lashed the city.
“The century-old KMC brick sewer line has pores which were silted up in the past few weeks. The manhole wall also has holes, which led to the water seepage into the station.These holes are being plugged now with grouting. In fact, grouting is being done at different locations of Park Street metro station and cement injected inside the diaphragm wall to prevent water seepage in future,” a Metro spokesperson said on Monday. In a statement released on Monday, the carrier said that between May 28 and July 15, 645 bags of cement have been injected into the diaphragm wall.
Asked to comment, a KMC engineer told TOI, “We don’t quite agree with Metro’s findings. We have also inspected the site and found that water was seeping through the diaphragm or diaphragm wall of the station box.”
Another engineer added, “Even if, for the sake of argument, one is ready to agree with Metro Railway that it is the KMC sewer that needs to be repaired to address the waterlogging that had occurred inside Park Street metro station, why are they (metro) injecting grout into the diaphragm walls?”
