Fresh water was released on Tuesday from the Mukerian hydel channel into the Kali Bein from where thousands of dead fish were recovered by environmentalist Balbir Singh Seechewal and his workers.
The demand for water through Kanjli tributary was raised for the survival of live fish in the bein. With the arrival of fresh water, the dissolved oxygen level has increased from 2.9 to 4.0 in the Bein.
Seechewal’s workers, who have been cleaning the bein for last three days, on Tuesday cleaned the bed of the rivulet and recovered huge quantities of dead fish.
They have recovered more than six quintals of dead fish so far. Sechewal has also written a letter to chief minister Parkash Singh Badal requesting for release of fresh water on a permanent basis so that no fish die in future.
“The district administration has completely failed in checking the flow of effluents in the bein,” he said. Meanwhile, the authorities have shifted the remaining fish to the government fishery for breeding. Sewerage board officials have diverted the outlet of waste discharge flowing into the bein and installed aerators to generate more oxygen.
They are also mixing chemicals in water to oxidise it.
Punjab Pollution Control Board (PPCB) chief GS Majithia said results of water samples taken on the first day found no toxicant in the bein water.
