State to restore Salem’s polluted Vasishta river

 

 

 

 

 

 

Critically polluted stretches of Vasishta river in Salem district will soon be cleaned up, thanks to a proposal by the state pollution control board to take up its ecological restoration. Vasishta river, a tributary of Vellar river, was recently officially declared the dirtiest river in the country among the 351 polluted rivers studied by Central Pollution Control Board. Sharing details about the PCB’s clean-up work, Tamil Nadu Pollution Control Board chairman A V Venkatachalam told TOI that it was for the first time that a portion of a critically polluted river was being restored.

 

 

 

 

 

The decision in this regard was taken following an order from the Principal Bench of the National Green Tribunal which wanted several critically polluted rivers in the state to be restored to its original status. Following the order, the Board decided to take up the restoration work, he said. The Vasishta river is critically polluted for about 10 km stretch, starting from Manivizhundhan to Thyaganur. Venkatachalam said he along with state environment secretary Shambu Kallolikar inspected the river stretch. During the inspection it was found that release of untreated raw sewage and untreated effluents from small dyeing units in this area are the two major sources of pollution.

 

 

 

 

 

The release of effluents into the river was mainly due to absence of effluent treatment plants in the area. Other industrial discharges are treated through common effluent treatment plant, he said. A detailed survey was conducted during which time the sewage and effluent outfalls were identified. The official team had also inspected all the tributaries of Cauvery. Besides, the catchment areas of the river were also inspected, he said. A detailed project report will be prepared by the board, which will be ready before the end of this year. Once it is ready, it will be sent to the government for its approval. Once the government approves the proposal the restoration work will begin, said the PCB chairman.
