According to information from sources within the tunnel construction company, it has been reported that water accumulation has been observed inside the Silkyara tunnel.
Asked by reporters, NHIDCL managing director Mahmood Ahmed did not immediately confirm the development but said the last section of the escape pipe was being pushed through the drilled passage.
Campaigners say that while development is needed, the breakneck pace is causing problems, including a surge of unregulated building development replacing forests that helped keep hillsides stable.
The NDRF men will go in through the pipe and once they reach the workers, they will use their equipment to start sending them out of the tunnel one by one.
