Mumbai Tunnels: Turning Sewage into Water Gold!

Mumbai is set to construct an 8.7 km water conveyance tunnel, a significant infrastructure project by the Brihanmumbai Municipal Corporation (BMC). This tunnel will link the upcoming sewage treatment plant in Dharavi to the BMC's water filtration plant in Bhandup, aiming to bolster the city's water supply. The tunnel's design allows for efficient transport of large water volumes, with the tertiary treated water intended initially for non-potable applications.

The project addresses Mumbai's pressing water shortage, which currently sees a deficit of approximately 400 million litres per day (MLD). The new sewage treatment plants, including the one in Dharavi, will collectively treat a substantial amount of wastewater. Initially, 50% of the treated water from Dharavi will be made available for non-potable uses such as gardening and road washing, with private stakeholders showing interest.
