Banned plastic was a big factor in the flooding that occurred in Chennai on Thursday. The local authority collected more than 180 tonnes of plastic debris and other solid waste in West Mambalam, where there were areas under knee-deep water, and water had already begun to flow through the canal.
An official said: “Several areas were inundated. Despite clearing the canal, water was not moving. Then every inlet of the canal was checked. We found a lot of plastic waste that had blocked the inlets now. As it rained, the water has carried the solid waste usually dumped on the roads, canal bunds, and tank bunds. Despite desilting, this solid waste caused several blockages.”
