Currently, the existing Bandra plant provides only primary sewage treatment before discharging it into the deep sea. The new facility will treat 360 million liters of sewage per day at the secondary level, with 180 MLD undergoing advanced tertiary treatment using Membrane Bio Reactor (MBR) technology. Once operational, the plant will significantly improve sea water quality and marine life, benefiting residents of Mahim, Bandra, Bandra-Kurla Complex, Kherwadi, and Santacruz.

Larsen & Toubro was awarded the contract for design, construction, and maintenance of the plant in May 2022, with work beginning on July 5, 2022. The project has a five-year timeline, with completion expected by July 2027.
