Environmentalists and residents have lauded the civic authorities for accelerating work to divert sewage from entering Powai Lake, but raised serious concerns over the Brihanmumbai Municipal Corporation’s (BMC) plan to transplant 112 trees for the construction of a sewage treatment plant (STP).

According to NGO Natconnect Foundation, the clean-up drive aimed at halting the daily discharge of 18 million litres of untreated sewage from 18 inlets into the 210-hectare wetland has gathered pace.
