Anbumani Ramadoss urges Tamil Nadu to release Chennai flood committee report

PMK president Anbumani Ramadoss urged the Tamil Nadu government on October 18 to publish the Thiruppugazh Committee’s flood mitigation report and implement its recommendations after heavy rain in Chennai, India, on October 17, The Hindu reported. His call puts renewed attention on what measures the government has taken to protect the city from flooding.

In a statement reported by The Hindu, Ramadoss described rainfall in several parts of Chennai as comparable in intensity to a cloudburst. He called for urgent flood prevention measures if such episodes become frequent. That description was his characterization of the rain; the report did not cite a measured rainfall intensity for it.

What Ramadoss wants disclosed

He said his Pattali Makkal Katchi had warned for more than five years that climate change could bring cloudburst-like conditions to Chennai and that stormwater drains and other flood prevention infrastructure needed strengthening. He also warned of potentially heavier rain in the coming days and raised the possibility of an El Niño effect. Those were warnings about future conditions, rather than reported rainfall outcomes.

Why Chennai’s drainage is at issue

The Greater Chennai Corporation says the city is vulnerable to monsoon flooding and standing water partly because its average land level is about two metres above mean sea level. Its flat terrain and tidal effects also contribute, according to the corporation. That geography makes drainage works relevant to residents facing waterlogged streets during heavy rain.

The corporation says the Tamil Nadu government appointed an advisory committee headed by Thirupugazh. On its stormwater department page, it lists 225 kilometres of committee-recommended drain works as completed and 70.26 kilometres as in progress. Those figures describe specific drainage works; they do not identify the full set of recommendations that Ramadoss wants published.
