KULAI: Schools of dead fish were found floating in the Taman Matahari Lake, here, today due to pollution from sewage.
The lake in Bandar Indahpura here recorded readings that indicated its water quality was polluted and possibly caused the fish to die.
State Environment Department (DoE) officers were mobilised to the lake to check the water quality following footage of the dead fishes, which were circulated on social media platforms.
They also conducted investigations to establish the source of the pollution.
Johor Health and Environment Committee chairman Ling Tian Soon said investigations revealed that the pollution was caused by a damaged component in the sewage treatment plant's waste system that caused its discharged waste to flow into the lake.
"The officers observed a black effluent in the sewage plant's drains.
"Further investigations led to the officers to a broken component in the plant's treatment system. It was damaged and had malfunctioned," Ling said.
Ling said the plant was ordered to shut its operations until the damaged component was repaired, and the DoE, health ministry and Kulai City Council will take the required enforcement actions against the plant's owners.
He added the water quality and the lake will be monitored continuously.
