Taking a serious note about the illegal emptying of slurry into the P&T nulla from Metro line three construction work at Sahar, the Brihanmumbai Municipal Corporation (BMC) had issued a notice to Mumbai Metro Rail Corporation (MMRC) asking the contractor to remove the silt.

The issue was first raised by Watch Dog foundation. Talking to mid-day, activist Godfrey Pimenta said, "The complaint filed by Watchdog foundation had an impact. BMC has sent a notice to Chief project manager Mumbai Metro Rail Corporation (MMRC) on September 14 and we demand immediate measures to stop the release of slurry into the nullah."
