Five textile dyeing and printing units in Periyasemur area on the outskirts of the city have been dismantled by the District Environmental Monitoring Committee for allegedly discharging untreated effluents into water sources and for operating without proper licence.

Committee members raided the units yesterday and found them discharging untreated toxic effluent into water sources. They also found that none of the five factories had obtained licences or the permission of the Pollution Control Board. Two units had obtained power supply by producing false records, officials said.

The factories were dismantled and the power supply disconnected. Pollution Control Board personnel said they would take action against the factory owners.

They said they had dismantled 119 such factories in and around Erode in the last five months for operating without any license.
