BMC Proposes ₹2,241-Crore Afcons Contract For Water Tunnel
The BMC in Mumbai wants to build a long water tunnel that will connect a new desalination plant to the city's water system.
This tunnel will be 7.175 kilometers long and will help bring clean water from the plant to the people of Mumbai.
The project will cost about ₹2,241 crore and is expected to take 45 months to complete.
The tunnel will be built using special machines that dig underground.
The BMC has chosen a company called Afcons Infrastructure Ltd to build the tunnel because they offered the lowest price.
The tunnel will also have a solar power system to save electricity.
This project is important because it will help Mumbai have more clean water in the future.
The BMC proposes a ₹2,241-crore contract to Afcons Infrastructure Ltd for a 7.175-km water tunnel linking the Manori desalination plant to Mumbai's water network.
The tunnel will run from Manori in Malad to Charkop Municipal Garden and Mahavir Nagar in Kandivali, with a diameter of 2.5 metres.
The project includes a 400 MLD capacity tunnel and pumping station, with initial phase handling 200 MLD.
The tunnel will be excavated 104–128 metres underground using two Tunnel Boring Machines (TBMs).
Afcons Infrastructure Ltd was the lowest bidder, quoting 1.82% below the BMC's estimated cost of ₹1,577 crore.
The project timeline is 45 months, with a 100-kW solar power system planned for the pumping station to reduce electricity consumption.
