OPINION | SOUTH MATTERS
Every monsoon, the same scenes return across South India’s big cities: roads turn into canals, underpasses close, homes take in water and commuters lose hours. Officials announce desilting drives, new drains and relief measures. Then the water recedes, the headlines move on and the city rarely gets a clear account of what failed.
That is the real urban-flood problem. Bengaluru, Chennai and Hyderabad do not lack warnings. They lack a public system that connects spending, planning, maintenance and responsibility.
Project completion is not flood protection
Government data reported by Business Standard in July 2026 show that 838 stormwater-drainage projects worth ₹3,017.13 crore were taken up under AMRUT. States reported 820 completed. Under the Smart Cities Mission, 102 of 106 drainage projects were reported complete by December 2025.
Those numbers tell us how much work was sanctioned and how much was marked complete. They do not, by themselves, tell residents whether a street floods less often, whether a drain can handle intense rainfall, or whether its outfall is clear. A completed project is an administrative milestone. Flood resilience is a result that has to be measured on the ground.
The same report notes that the Union government does not maintain a national database of urban flooding or waterlogging incidents. Without consistent city-level records, it is difficult to compare performance, identify repeat failures or hold agencies to a measurable standard.
The evidence is already visible
In Chennai, a University of Madras study reported in October 2026 found that between 2000 and 2024 the city’s built-up area grew by 7.6%, vegetation cover fell by 26.14% and water bodies shrank by 22.54%. The study points to the combined effect of urban expansion, shrinking natural buffers and drainage gaps.
A 2026 research paper on Bengaluru, drawing on 27 years of rainfall and groundwater data, describes how expanding built-up surfaces and the loss of lake systems are connected to both flooding and groundwater stress. The problem is not simply that rain has become inconvenient. Cities have reduced the space and routes through which water can move and soak into the ground.
These findings do not mean every flood can be prevented. Extreme rainfall can overwhelm even well-designed infrastructure. But that is precisely why cities must publish the assumptions behind their drainage plans: the rainfall intensity they are designed for, the catchment they serve, the condition of connected lakes and channels, and the maintenance schedule.
Make accountability visible before the next storm
State governments and city administrations should publish a ward-level flood-resilience dashboard before each monsoon. It should identify recurring waterlogging points, the agency responsible for each drain, project costs, completion dates, design capacity, desilting records and the status of blocked links or encroachments. After major rain events, the same dashboard should record which locations flooded and whether the promised infrastructure performed as designed.
Independent technical audits should examine projects that repeatedly fail, not just whether contractors completed the work. Audit findings and action-taken reports should be public. Where several agencies share responsibility for a waterway, one clearly identified authority must be answerable for coordination.
The Centre has approved an Urban Flood Risk Management Programme covering Bengaluru, Chennai and Hyderabad in its first phase, with other cities including Visakhapatnam and Thiruvananthapuram in the second phase. That support matters. But funding is only the beginning; residents need evidence that the money is reducing risk.
South Indian cities cannot keep treating floods as a seasonal surprise. Rainfall will vary, and no administration can promise a flood-free city. It can, however, show what it built, what it maintained, what failed and what it will fix. The next monsoon should not be the first time citizens discover whether this year’s announcements worked.
