With a deadline to complete the Gargai dam project by 2028-end, and complete all allied works by 2030, construction can finally begin as the Brihanmumbai Municipal Corporation’s (BMC) General Body approved the proposal on Thursday. The body, comprising the newly appointed 227 corporators, discussed the proposal for 90 minutes before it was passed on to the Mahayuti alliance which has a majority in the house.

The proposal was passed by BMC’s Standing Committee on April 1, 2026, after which it was presented to the General Body for approval. As part of the project, BMC will hire eight kinds of experts to make up for the lack of in-house expertise to facilitate the work, including a cultural expert for rehabilitation, an environmental conservationist, a forest conservationist, and an agriculture supervisor.
