The catastrophic flooding in Chennai is the result of the heaviest rain in several decades, which forced authorities to release a massive 30,000 cusecs from the Chembarambakkam reservoir into the Adyar river over two days, causing it to flood its banks and submerge neighbourhoods on both sides. It did not help that the Adyar’s stream is not very deep or wide, and its banks have been heavily encroached upon over the years.
Similar flooding triggers were in action at Poondi and Puzhal reservoirs, and the Cooum river that winds its way through the city.
While Chief Minister J Jayalalithaa said, during the earlier phase of heavy rain last month, that damage during the monsoon was “inevitable”, the fact remains that the mindless development of Chennai over the last two decades — the filling up of lowlands and choking of stormwater drains and other exits for water — has played a major part in the escalation of the crisis.
