Powai Lake Rejuvenation Gets Major Boost As Sewage Diversion Project Nears Completion
The BMC’s sewage pipeline project along Powai Lake has entered its final phase and is expected to be completed by June-end, meeting NGT directives. The project will divert 18 MLD of sewage away from the lake, aiding its rejuvenation. Officials say improvements in water quality may become evident by October during dry-weather conditions.

The installation of sewage pipelines on the banks of Powai lake has
reached the final stage, BMC officials ,who are involved with the project , said during an interaction with members of the Powai advanced locality management (ALM). The project has progressed significantly despite challenges such as difficult terrain, rising construction costs, fuel price fluctuations and labour constraints. The progress of the project has been stymied only in some areas like Powai Udyan and IIT Bombay due to extremely hard rock strata.
However, the project is expected to be completed by the end of June,
thus fulfilling the National Green Tribunal’s directives. The on-target
completion of the project will result in 16 mld of sewage ingress being
diverted to Bhandup Pumping Station and 2 mld of sewage diverted to
the STP at Peru Baug near Westin Hotel, Powai. BMC sources have
also indicated that the construction of the STP near Suvarna Mandir at
Powai may be hastened and completed within a year to facilitate the
rejuvenation of the lake.

While the pipeline project will be completed by June-end, its
effectiveness will be visible only in dry-weather conditions, possibly in
October, when the quality of the lake water can be ascertained.
To ensure complete sewage disposal, sewage generated at present
within the IIT Bombay campus is also pumped into the BMC sewer
network and diverted to the Bhandup pumping station. The BMC has
also advised IIT Bombay to construct a sewage treatment plant inside
the campus.
The installation of sewage pipelines is a significant milestone in the
rejuvenation of Powai Lake and represents a laudable effort in the
diversion of major polluters of the lake. However, true ecological revival
demands sustained commitment, strict implementation and transparent
collaboration among all stakeholders to protect the lake's ecosystem.
