Afcons Infrastructure has a letter of acceptance from Mumbai’s civic body for a Rs 1,918 crore water tunnel under the western suburbs. For anyone who owns or rents machines, the headline value is the least interesting part. A 7-km tunnel at a 2.5-metre bore is small-diameter work, so the equipment demand sits at the shaft heads and on the muck run, not at the tunnel face.
The company put the award out through its own release on Thursday afternoon; the news agency ANI carried it the same day and CNBC TV18 ran it separately. Executive chairman Krishnamurthy Subramanian called the tunnel a critical step towards a sustainable water supply for Mumbai, and managing director S Paramasivan said the company was partnering BMC again. The tunnel feeds the planned Manori desalination plant, sized at 200 million litres a day with provision to double later.
Two things the announcement does not give: a completion period and a tunnelling method. Both decide what gets bought and rented.
Start with the bore. At 2.5 metres finished diameter this is nowhere near metro-tunnel territory, so the segment-erector-and-gantry-train picture most people carry does not apply. A drive that narrow is usually a small slurry or micro-tunnelling machine pushed from shafts, or drill-and-blast where the rock allows. Until Afcons says which, the fleet at the face is guesswork.
The fleet on the surface is not. Every shaft needs excavation and support, then becomes a works yard for the length of the drive. That pulls crawler cranes over the shaft collar handling pipe strings and muck skips; excavators working the shaft and loading spoil; a tipper cycle hauling muck through some of Mumbai’s most congested roads; batching plant with transit mixers and concrete pumps for collars and lining; and compactors plus paving gear when the shaft sites are reinstated.
Site conditions should shape what you pitch. This runs under dense suburban roads with live utilities and residents on both sides, so short-tail and compact machines that work inside a hoarding line earn their keep in a way a bigger machine cannot, and haulage gets squeezed into night windows. Fleet owners quoting Mumbai civic work know this; those coming off highway jobs tend to learn it expensively.
Our take: don’t read an LoA as a purchase trigger. It is an acceptance letter, not a notice to proceed, and Afcons already has Kasheli-Mulund running for the same client, so much of the specialist tunnelling plant may redeploy rather than be bought new. What is genuinely additional is the surface and haulage side, which is also the part usually let to subcontractors. The wider signal matters more than this one contract: Mumbai’s water programme is becoming a standing tunnelling pipeline with repeat packages, and a contractor building shaft-and-haulage capability for it is not buying for one job.
Bidding on urban tunnelling or shaft work? Compare crawler cranes, excavators and concrete plant on DesiMachines before you price the job, and check what equipment finance costs on a fleet you will hold for a multi-year contract.
Afcons has stated the value at Rs 1,918 crore including GST and operations and maintenance, under a letter of acceptance from BMC dated 6 August 2026.
From the proposed water pumping station at Manori to Charkop Municipal Garden, 4.63 km, then a further 2.545 km to Mahavir Nagar in Kandivali. Total length is about 7.175 km at a 2.5-metre diameter.
The tunnelling method has not been disclosed, so face equipment is unknown. The surface fleet is predictable: crawler cranes over the shafts, excavators for shaft work and spoil, tippers for muck haulage, batching plant with transit mixers and concrete pumps, and compactors for road reinstatement.
