Nine illegal dyeing units that were functioning near River Cauvery at Pallipalayam in Tiruchengode Taluk were removed in a drive carried out by the Tamil Nadu Pollution Control Board (TNPCB) on Wednesday.
TNPCB sources said that all the units were manual dyeing units.
“Ninety eight masonry (cement) tanks and nine steel tanks that were used for boiling the yarn were demolished using an earthmover. Two units were located on the banks of River Cauvery at Pudanchandhai and directly let the effluent into the river. The remaining seven units were located in a radius of 1 to 1.5 kms from the river. Six of them were letting the effluent into drains that led to the river.
“One of the units located near Alamedu Bus Stop did not let effluent into the drains. With walls surrounding the unit, the effluent was discharged into a man made pond inside its premises and this directly affected underground water in that locality. We were alarmed to see sulphur black colour – which is tough to treat – in the pond and closed it with mud,” the official said. District Environmental Engineer M. Murugan, Assistant Environmental Engineers (AEE) T. Palanisamy, M. Selvakumar and S. Sathyan, AEE of the TNPCB Flying Squad in Erode D. Jayalakshmi and Police were also present during the drive.
