Mumbai floods persist as outdated drainage system fails

Heavy monsoon rain has battered Mumbai for five consecutive days, leaving large parts of the coastal city inundated. The flooding is attributed to the city's low-lying topography, with many neighborhoods below sea level, and a colonial‑era drainage network that cannot cope with a population now exceeding 20 million. Clogged sewers, undersized pipes, and illegal constructions that block natural water pathways have further hampered runoff.

Experts also cite climate‑driven factors such as rising sea levels and intensified rainfall patterns. The Brihanmumbai Municipal Corporation (BMC) is responsible for drainage maintenance and has launched modernization projects, but critics say progress is slow and hampered by corruption and contractor collusion. The situation has disrupted transportation, halted train services, and forced residents to navigate water‑logged streets.

Calls for a comprehensive master plan include full system upgrades, mangrove preservation, stricter enforcement against unapproved building, and rain‑water harvesting to mitigate future floods.
