MUMBAI: The under-construction Acharya Atre Chowk station on Mumbai’s fully underground Metro Line 3 (Colaba–Bandra–SEEPZ) corridor experienced water seepage on following a spell of intense rainfall on Monday.The Mumbai Metro Rail Corporation Ltd (MMRC), which is executing the project, confirmed the incident and said the affected section is not yet open to the public.The incident occurred at an entry/exit structure located along Dr. Annie Besant Road. According to MMRC, “Due to the sudden and intense rainfall today, water seepage was reported at the under-construction entry/exit structure of Acharya Atre Chowk station. The incident occurred when the RCC water-retaining wall constructed at the entry/exit collapsed due to a sudden ingress of water from an adjoining utility.”While the seepage was limited to an area under construction, as a precautionary measure, train services between Worli and Acharya Atre Chowk have been temporarily suspended. “However, the train services from Aarey JVLR to Worli are not affected and are running regularly,” the agency clarified.This incident has raised concerns about waterproofing systems and drainage readiness on the high-profile Rs 37,000-crore corridor, especially with monsoon season approaching.MMRC assured that safety protocols are being followed and urgent repair work is in progress. “Our engineering and safety teams are on-site and working on a war footing to address the issue. We deeply regret the inconvenience caused to our commuters and request their patience and cooperation. Safety remains our highest priority, and services will resume only after all systems are fully secure and operational,” the statement said.
