BWSSB Bangalore blocks effluents into Hebbal plan
Industrial waste which was earlier getting illegally dumped directly into the outflow tank of the plant at the exit gate has been stopped and security personnel man both entrances and exit gates and have barricaded the outflow area. After the incident of assault on chief conservator of forest U V Singh on February 20, BWSSB issued new guidelines and has stopped taking effluents from industries for treatment.
The BWSSB’s secondary sewage treatment plant near Hebbal has not permitted a single industry to discharge effluents for treatment. “Since that attack, we stopped treating chemical effluents of private industries. Police patrolling has also been stepped up,” S P Rudramurthy, additional chief Engineer, BWSSB said.
Miscreants throwing pollutants directly into treated water was not new, but it was highlighted after Singh’s investigation, said Gopalakrishna Raju, director, Lumbini Garden, who operates from Nagawara Lake. “It was becoming inevitable for us to draw water from the storm water drain next to the lake. This drain would have water treated for secondary level. Since 2007, We have stopped drawing water from the drain as fish in the lake die because of pollutants. The unhygienic atmosphere led to fewer visitors,” he said.
The treatment plant lets water enter the main storm water drain of Hebbal valley and that gets mixed with sewage water and moves towards Amruthahally. “We treat water as per the norms. If private operators at the lake don’t want to use treated water, what can we do?” said a BWSSB official at the plant.
Though the plant’s capacity is 60 million litres per day (MLD), the plant currently treats only 40-45 MLD. BWSSB issued new guidelines where they permit treating effluents only if applications received from industries or domestic consumers for discharge of effluents are in the format prescribed by BWSSB Bangalore. Related documents must be attached and they will be disposed of on top priority.
