Chennai’s monsoon test
Chennai officials are accelerating flood-mitigation efforts, including de-silting and stormwater drain construction, ahead of the Northeast monsoon. While the government reports a reduction in flood-vulnerable locations, local representatives have raised concerns regarding transparency and lack of consultation.
Why it matters
Effective urban infrastructure management is vital for climate resilience in rapidly growing coastal cities prone to extreme weather events.
Call it the continuum or an early image-building exercise, Chief Minister C. Joseph Vijay, who also holds the Municipal Administration portfolio, has already deployed Ministers and senior officials to take up flood-mitigation works well ahead of the onset of the Northeast monsoon. He has instructed that all de-silting and stormwater drain (SWD) works be completed as early as possible.
Official data shows that the flood-vulnerable locations within the Greater Chennai Corporation (GCC) have dropped from nearly 800 in 2015 to 389 in 2023. The figure is 219 for the 2026 Northeast monsoon. The list of vulnerable locations is being continuously reviewed based on field-level assessments, rainfall patterns, and the effectiveness of the completed flood-mitigation works, said GCC officials. The micro-level SWD works are 95% complete, but there are severe capacity constraints along the Buckingham Canal, Adyar, and Sholinganallur, officials added.
