ANOTHER suspected act of sabotage on the Selangor water supply was detected yesterday with chemical waste being poured into the Indah Water Konsortium Sdn Bhd (IWK) manholes near Bandar Bukit Mahkota, Bangi, Selangor.

Selangor’s State Standing Committee on Tourism, Environment and Green Technology and Indigenous Affairs chairman Hee Loy Sian (picture) said swift action by the authorities had, however, managed to prevent the residue from entering the Semenyih Water Treatment Plant (WTP) at the downstream level.

“The Selangor Department of Environment received a report on the pollution at 10pm and then contacted the Kajang Municipal Council for immediate action.

“The waste was found to have overflowed from the manhole and then flowed to the lake which is located in a clubhouse near the area,” he said at a media briefing related to river pollution in Shah Alam yesterday.

He said 20 bags of activated carbon have been released into the lake to block and neutralise the chemical waste from continuing to flow into Sungai Beranang.

Hee said the chemical waste that smelled like hair dye was then removed by IWK trucks and the cleaning work was completed at 2am.

He added that the IWK plant in the area also had to be closed yesterday so that cleaning work could be carried out.

The distance of the IWK plant location is about 1km from the lake,” Hee added.

“We suspect that the mastermind of the activity committed the removal of prohibited substances by using a truck to avoid being detected.

“If there was no swift action yesterday, the plant closure may occur as the contaminated water is expected to be brought to the Semenyih WTP within 10 hours,” he said.

This is also the third pollution incident to occur at the same location since 2018.

Hee also said the act is a sabotage towards the Selangor water and river system, similar to what had happened in Taman Velox, Rawang.

He said it could not be ascertained yet if the culprit’s motive for dumping the waste is linked to any specific agenda.

However, he did not rule out that it could be connected to previous incidents that had occurred repeatedly at almost the same spot.

Last month, the Selangor government also amended a law to give a more stringent penalty to those who polluted any part of the riverways, including IWK manholes and drainage systems which eventually will affect the operation at Pengurusan Air Selangor Sdn Bhd’s WTP.
