BMC To Start TBM Work On 7.13-Km Kasheli-Mulund Water Tunnel By September

Mumbai's ambitious Kasheli-Mulund water tunnel project is set to enter its most crucial phase, with tunnel boring using a Tunnel Boring Machine (TBM) scheduled to begin by September. The 7.13-km-long, 4.5-metre-diameter tunnel is expected to be completed by October 2030.

The project is part of the BMC's plan to improve the efficiency of the city's water distribution system by reducing transmission losses through a new underground water conveyance network. Additional Municipal Commissioner (Projects) Abhijit Bangar reviewed the project during a site visit and directed officials to maintain the pace of work while ensuring quality, safety and adherence to timelines.

The tunnel has been under construction since September 2024. All components of the 5.3-metre-diameter TBM, along with the 14-km-long conveyor system required for excavation, have reached the project site. At Kasheli, excavation of the 128-metre-deep recovery shaft, which will be used to retrieve the TBM after tunnelling, has progressed to a depth of 27 metres.

At the Mulund end, the 134-metre-deep launching shaft has been completed, along with excavation of the 95-metre assembly tunnel, the 40-metre tail tunnel and the 25-metre tube tunnel. RCC lining work for the shaft has also commenced. The project will provide an additional underground corridor to carry water from the Bhatsa system, helping reduce transmission losses and improve the reliability of Mumbai's water supply.

Bangar said the project will be completed as per schedule and maintain the highest standards of construction quality and safety. The BMC is also working on another project to transport tertiary-treated wastewater, with tunnel boring for the 11.61-km Ghatkopar–Bhandup tunnel scheduled to begin in January 2027.

The BMC's underground tunnel project to transport tertiary-treated wastewater has reached a key milestone. To expand the reuse of treated wastewater, the BMC is constructing two dedicated conveyance tunnels linking Ghatkopar STP to the Bhandup Complex and Dharavi STP to Ghatkopar STP.

The project is expected to improve the city's water distribution system and reduce transmission losses. The completion of the project will provide a reliable water supply to the city's residents. The BMC's efforts to improve the city's infrastructure will have a positive impact on the lives of Mumbai's residents.

The project is a significant step towards improving the city's water supply system. The use of a TBM will ensure that the tunnel is constructed efficiently and safely. The project's completion will be a major milestone in the BMC's efforts to improve the city's infrastructure.

In conclusion, the BMC's Kasheli-Mulund water tunnel project is a significant step towards improving the city's water supply system. The project's completion will provide a reliable water supply to the city's residents and reduce transmission losses. The BMC's efforts to improve the city's infrastructure will have a positive impact on the lives of Mumbai's residents.
