Mumbai, Feb 01: In July this year, the BMC will commence excavation work for its ambitious underground water tunnel project linking Kasheli in Bhiwandi, Thane district, with Mulund in Mumbai’s eastern suburbs.

The 7.1-km-long water supply tunnel is designed to transport water from the Bhatsa dam, one of the seven lakes supplying potable water to Mumbai, to several parts of the city.

Site visit and project progress

BMC Commissioner Bhushan Gagrani carried out a site visit at Mulund Check Naka on Sunday. “A 134-metre-deep launching shaft is being constructed at Mulund Check Naka, and excavation work up to a depth of 130 metres has been completed. After the tunnel mining work is completed, a 128-metre-deep recovery shaft will be constructed at Kasheli (Bhiwandi) to take out the tunnel mining machine,” Gagrani said.
