Brihanmumbai Municipal Corporation (BMC) is planning to conduct a survey of 227 stormwater drain (SWD) outfalls across Mumbai. With this, BMC plans to assess and prevent the flow of sewage into creeks, rivers and the Arabian sea. It is part of a project to remediate the city’s drainage network, including sewers and SWDs, after various orders of the National Green Tribunal and the Supreme Court, in response to a public interest litigation by a city-based environment group. As per the BMC’s SWD department’s records, there are at least 185 outfalls into the Arabian Sea, and 42 that open out into the Mithi, Dahisar, Poisar and Oshiwara rivers. This survey is meant to suggest short-term pollution abatement measures.
