Mumbai’s iconic Bandra Talao, a 7.5-acre Grade II heritage lake in Bandra West, has been completely drained as part of an extensive restoration initiative undertaken by the Brihanmumbai Municipal Corporation (BMC).
The once water-filled urban lakebed has now turned into a vast expanse of exposed mud, thick silt layers, and sludge, with heavy machinery and pumps actively engaged in cleanup operations.
According to civic officials, the restoration work is being carried out in phases. The first phase includes complete dewatering of the lake followed by large-scale desilting to remove years of accumulated waste and sediment. The second phase will focus on beautification measures and the development of improved public amenities around the lake’s perimeter.
Officials noted that Bandra Talao has faced serious ecological challenges for several years. Studies conducted during preparation of the lake’s detailed project report reportedly revealed extremely high biochemical oxygen demand (BOD) levels of nearly 100 mg/litre — far above the acceptable level of below 5 mg/litre typically seen in healthy water bodies. Authorities believe the poor water quality is mainly due to sewage seepage from surrounding underground sewer lines, despite the absence of any direct sewage discharge into the lake.
During the dewatering process, officials stated that no living aquatic species were found in the lake. However, two dead turtles were discovered, highlighting the deteriorating environmental condition of the waterbody.
To improve the lake’s long-term health, the BMC plans to construct a one million litres per day (1 MLD) sewage treatment plant near the site. Treated water from the facility will later be released into the lake to improve water circulation, reduce stagnation, and maintain better oxygen levels.
The restoration project is expected to significantly improve the ecological condition and overall appearance of one of Mumbai’s oldest and most prominent lakes.
Senior Maharashtra minister and BJP leader Ashish Shelar, who represents Bandra West constituency, recently surveyed the restoration work. In a post on X, he said Bandra Talao is not just any water body but a part of Bandra's identity and culture. The minister has also instructed officials to expedite work and ensure the timely completion of the project.
The desilting work has been underway for nearly two weeks.
