Making a suo motu statement in the state assembly, he said compound walls would be constructed along the banks of the river in the Tirupur Corporation limits.
'Baby canals' would also be constructed to carry drainage water from homes and factories, he said.
A hosiery hub, Tirupur has been facing the issue of water pollution, mainly from dyeing units, with Noyyal river bearing the brunt.
As part of the proposal, setting up of effluent treatment centres, construction of parks along the river banks and upgrading anaicut areas would also be taken up, he said.
A detailed project report would be prepared for this purpose, the Chief Minister added.
In a separate announcement, he proposed allocating Rs 25 crore towards procuring surveillance cameras that could automatically read vehicle registration plates.
The pilot project was aimed at identifying accident-prone roads where the cameras could automatically read the registration plates, he said, without elaborating.
