Mumbai’s ambitious new wastewater solution — and why it matters

Mumbai is gearing up for a major transformation in its sewage-treatment infrastructure with the upcoming Bandra 360 MLD WwTF (Waste Water Treatment Facility). Once completed, it promises to be among the most advanced wastewater treatment installations in India — and potentially a model for urban water recycling.

What is “Bandra 360 MLD WwTF”? ( Mumbai’s ambitious new wastewater solution — and why it matters )

• The Bandra WwTF is being developed by Brihanmumbai Municipal Corporation (BMC) near Bandra Reclamation, close to the Bandra–Worli Sea Link. The Times of India+2Free Press Journal+2

• The facility’s total processing capacity will be 360 million litres per day (MLD). The Times of India+2Free Press Journal+2

• Importantly, half of this — 180 MLD — will receive tertiary-level treatment using advanced Membrane Bio Reactor (MBR) technology. Project X India+2Business Standard+2

Modern features — beyond just cleaning wastewater

• The plant is not just functional, but thoughtfully designed. It will include a rooftop landscape garden — potentially the size of a football field — making it one of the first green-topped wastewater treatment facilities in India. This garden aims to green the facility and integrate it with the cityscape. Mumbai Mirror+2Hindustan Times+2

• In addition, plans include a viewing gallery, knowledge centre, and public-facing facilities to raise awareness about water recycling, sustainability and marine conservation. Mumbai Mirror+2The Indian Express+2

• The use of MBR technology (from a reputed provider like Veolia) ensures high-quality effluent, making treated water suitable for reuse in non-potable applications, cutting down freshwater demand. Business Standard+1

Where the project stands — and when to expect completion

• As of early 2025, around 21% of construction work on the Bandra plant has been completed. The Times of India+2Free Press Journal+2

• The project was awarded to Larsen & Toubro (L&T) in 2022 under the broader city sewage-overhaul initiative. India Infra Hub+1

• The target for full commissioning of the plant is July 2027. Project X India+2Free Press Journal+2

Why this matters — for Mumbai and its residents

• The new plant will help treat a large volume of sewage that currently gets only primary treatment and is discharged directly into the sea. Once operational, it will significantly improve the quality of sea water and aid marine life — a major win for Mumbai's coastal ecosystem. The Times of India+2First Construction Council+2

• The treated water can be recycled for non-potable use, reducing pressure on fresh water supply — critical for a city as densely populated as Mumbai. The design of green spaces and a public-facing facility also reflects a shift towards integrating infrastructure with community and environment.

• By combining cutting-edge wastewater treatment technology with green design and community outreach, the Bandra WwTF sets a benchmark for sustainable urban infrastructure. ( Mumbai’s ambitious new wastewater solution — and why it matters )
