After at least a decade, the Brihanmumbai Municipal Corporation (BMC) has made headway in dealing with 185 lakh tonnes of legacy waste at the oldest dumping ground in the city -- the Deonar Dumping Ground.
In response to the civic body's tender for the bioremediation of 185 lakh tonnes of legacy waste, with disposal of excavated/processed/segregated material and reclamation of 110 hectares of land at the Deonar Dumping Ground, Navayuga Engineering Ltd has emerged as the lowest bidder.
Navayuga quoted 7.29 per cent above BMC’s estimated cost -- beating HG Infra, which quoted 11.83 per cent above the estimated cost, and Re Sustainability, which quoted 24.8 per cent above the estimated cost. The project will now commence at a cost of Rs 2,540 crore. However, this is higher than BMC’s original estimate of Rs 2,368 crore. The per-tonne processing cost will rise to Rs 1,373.35, up from the estimated Rs 1,280.
The contract period for the project is three years, including the time needed for mobilisation and the annual monsoon period.
In April 2013, the High Court had directed the civic body to close the dumping grounds at Deonar and Mulund within three months. This was followed by multiple extensions, and BMC gradually reduced the amount of waste dumped at Deonar over the years. In October 2024, the Maharashtra cabinet approved the proposal to hand over a portion of the Deonar dumping ground for the Dharavi Redevelopment Project Pvt. Ltd.
The scope of the tender floated by BMC includes scientific treatment and removal of around 185 lakh metric tonnes of legacy waste -- deposited over many decades at the Deonar Dumping Ground -- ensuring environmental sustainability.
It includes excavation of landfill material, bioremediation and segregation, transportation of inert material and refuse-derived fuel (RDF) to various users, and leachate and odour management.
Deonar Dumping Ground is India’s oldest and largest dumping ground, operational since 1927.
It covers an area between 126–132 hectares, bordered by Thane Creek on three sides and a slum on the fourth side. The estimated height of the accumulated garbage is 35-40 metres, with an average height of 17 metres.
