The illegal discharge of slurry by the Metro III (Colaba-Bandra-Seepz) contractor into stormwater drains, and lack of enough dewatering pumps at the construction sites, is causing unusual waterlogging in South Mumbai. On June 28 after heavy rainfall, there was waterlogging in Nariman Point near Sarang Building, which is home to a Bombay HC judge, besides other areas.

BMC staff from A ward (Churchgate, CST) then inspected all four upcoming Metro III station locations (Cuffe Parade, Vidhan Bhavan, Churchgate and Hutatma Chowk) and found many issues.
