Mumbai: Following the financial bid opening on Friday, M/s. Navayuga Engineering Company Ltd. (NECL) has emerged as the successful bidder for the Rs 2,368 crore Deonar landfill bioremediation project, quoting 7.29% above the estimated cost.
The project, now valued at Rs 2,540 crore, aims to treat 185 lakh tonnes of legacy waste over three years, starting post-monsoon in October 2025. It is a key step toward freeing up land for the Dharavi Redevelopment Project.
After three extensions of the bidding process, the BMC received proposals for the Deonar landfill bioremediation project. Among the contenders—Hyderabad based firm NECL, Re Sustainability Ltd., and H.G. Infra Engineering Ltd.—NECL emerged as the lowest bidder and secured the contract.
NECL brings experience from major infrastructure projects, including the 47.8 km Vijayawada Bypass, the Eastern Freeway extension (Rs 2,682 crore), and the 13-km Thane Coastal Road (Rs 2,727 crore).
"Bidders quoted above estimates due to the massive logistics involved, though the final price reflects competitive market rates. Approvals from multiple state agencies are pending, as the site falls under CRZ norms and is adjacent to mangroves regulated by the environment department," said an official.
The lowest bidder has quoted Rs 1,373.35 per tonne for the bioremediation of legacy waste at the Deonar dumpsite. The contract will be awarded to the successful bidder after administrative approval. However, work will commence in October, as monsoon conditions and wet waste can affect bioremediation and related processes.
On May 14, the BMC floated a tender for the bioremediation project, with the goal of clearing 23, 000 metric tonnes of legacy waste daily using a fleet of 1,200 vehicles. While NECL quoted 7.29% above the estimated price, HG Infra quoted 11.53% above the price and RE Sustainability quoted 24.8% above the estimated price of Rs 2368 crores.
Deonar dumping ground, operational since 1927, is Mumbai’s oldest and largest landfill. Spread across 120 hectares, it is burdened with massive mounds of untreated waste and remains a major environmental concern for the city.
