They dump tonnes of effluents into Cauvery, Bhavani rivers that feed lands of thousands of farmers

Erode and Namakkal have emerged safe havens for scores of dyeing units that had to shut shop in Tirupur after the Madras High Court ordered their closure for flouting pollution norms two years ago. In spite of the efforts of the Tamil Nadu Pollution Control Board (TNPCB), several illegal units continue to flourish in these districts and dump tonnes of effluents into the Cauvery and Bhavani rivers that feed agricultural lands of thousands of farmers.
