Micro, Small and Medium Enterprises (MSMEs) in Chennai and its surrounding districts are lamenting that despite repeated flooding in industrial estates, little has been done to address the issue. For instance, the Ambattur Industrial Estate, spread over 1,450 acres and housing over 1,800 units, always gets flooded during heavy rain. An entrepreneur at this estate said: “Every year, we have meetings with the government after the rain. We submit details on the waterlogging every year. But nothing much happens. Flooding here has been happening for several years now. Surplus water from Ambattur lake passed through the north phase (third sector) of the industrial estate. This is the main reason for flooding this time,” G. Aravind, president, Ambattur Industrial Estate Manufacturer’s Association, said. A valve manufacturer at the estate, said that despite having increased the height of walls and floors after 2019, water seeped in.
