Chennai's monsoon test: the TVK government's first flood season is already running late

Chennai's first monsoon under the TVK government has not yet arrived, but the excuses already have. With the northeast monsoon days away, the state government announced on September 29 that the deadline for flood-mitigation works across Chennai and its suburbs would be pushed from September 30 to October 15. The northeast monsoon typically sets in over Tamil Nadu in the third week of October. The margin for error, in other words, is measured in days. The India Meteorological Department has forecast a normal monsoon, with a strengthening El Nino likely to intensify late-season rainfall. Chief Minister C. Joseph Vijay, who also holds the Municipal Administration portfolio, has moved early and loudly: ministers and senior officials deployed across corporation zones, twice-weekly inspections ordered, and a high-level review at the Secretariat. The official numbers sound reassuring. Flood-vulnerable locations have fallen from nearly 800 in 2015 to 219; micro-level drain works are 95 per cent complete; and 400 machines are desilting the Adyar, Cooum, Kosasthalaiyar and Araniyar rivers and the Buckingham canal under a Rs 42-crore programme meant to cut flooding by 70 to 80 per cent. Look closer and the reassurance thins. Only 52 per cent of monsoon power works are complete in central Chennai - T. Nagar, Anna Salai, Teynampet, Royapettah, Triplicane and Mylapore - and 56 per cent in the western belt, per the power utility's own data. Metro Water's third phase of sewer cleaning runs October to December - during the monsoon itself. Then there is who gets to know what. MDMK councillor S. Jeevan of Ward 35 in Perambur said he had not been able to meet the assistant engineer for ten days: "Elected representatives do not know what is happening during flood preparedness inspections." He warned of high flood risk from delayed desilting of the Kodungaiyur canal. Activist Haris Sulthan offered a colder reading: the five drinking-water reservoirs hold 4.5 TMC against 11.7 TMC of capacity, and beyond routine annual works, no major new flood-mitigation has been taken up in previously inundated areas like Medavakkam, Chitlapakkam, Hasthinapuram and Kadaperi. He credited the TVK government for cancelling "cosmetical lake-front development" tenders, while demanding deeper desilting. Experts are blunter. Urban planner K.P. Subramanian wants flood plains and lake margins declared no-development zones. Climate researcher D. Raghunandan says the drain network must handle 100 to 200 mm in a few hours, not evenly spread volumes. Professor S. Janakarajan notes 70 to 80 per cent of rainfall runs off to the sea for want of coordination between departments. Even finished works carry an asterisk: GCC Commissioner G.S. Sameeran concedes "severe capacity constraints" along the Buckingham Canal, the Adyar and Sholinganallur, leaning on "temporary solutions, such as pumping facilities". In Velachery, workers are reportedly hesitant to clear a blocked closed canal because of poisonous gas - a flood risk sitting in the dark, weeks from the rains. The question stands: is the new government prepared, or will Chennai brace for another deluge? Press releases do not drain streets.
