Some intense showers over a 24-hour interval in north Chennai this time round, resulted in over 30 cm of rainwater. Although the rainfall itself got here in bursts, due to staggered showers, the Better Chennai Company, with its intensive stormwater drain work this yr, might need simply but received the primary spherical.

It needed to. The flooding and failure of the final monsoon, may very well be laid on the door of the AIADMK authorities that had simply been voted out. However not, and positively not this yr, when Company Councillors had been elected after a spot of a decade, and have been immediately answerable to the residents of Chennai.

The DMK has a fame of enhancing metropolis infrastructure in Chennai each time it’s in energy. The town obtained a veteran bureaucrat in Gagandeep Singh Bedi as Company Commissioner, and work in the direction of flood prevention was set in movement with Chief Minister M.Ok.

However on this case, we’ve got completed many of the smaller initiatives in six months, having began in April.

We additionally obtained the suggestions from a technical group led by IIT Madras,” he mentioned. 

The seat of the native physique — Ripon Constructing was not flooded this yr. Nor have been core areas together with T. Nagar, Adyar, Mylapore, Ashok Nagar and Velachery. One other facet that has helped, is the fixed suggestions from the elected representatives – councillors.
