Water Board has fixed July 20 as the deadline for completing the underground sewerage tunnelling work near Basheerbagh. The total clearing of the site including conversion of open drive pit into closed inspection manhole should be over by July 30, said Board’s managing director, Adhar Sinha.

The technical committee concluded that the balance length of 12 meter near the ramp portion of flyover can be completed with due precautions for removal of the boring machine from the receiving pit and to demobilize the machinery and equipment away from the site.
