Sungai Langat and Cheras water treatment plants shut down

PETALING JAYA: Several areas in the districts of Kuala Lumpur, Petaling, and Hulu Langat will be experiencing temporary water disruption after two water treatment plants were shut down last night (7 Oct) due to odour pollution.
Syabas Corporate Communications head Amin Lin Abdullah said the plants affected were the Sungai Langat and Cheras water treatment plants and the source of the contamination was suspected to be from the Semantan River in Pahang.
"The Sungai Langat and Cheras water treatment plants were shut down at 8:30pm and 10:00pm respectively due to odour pollution suspected from the Semantan River in Pahang.
"Both of these plants receive raw water supply from the same river," Amin Lin said in a statement today.
He said water from the Sungai Langat dam was released into the river last night at about 9:45pm in an effort to mitigate the contamination.
Amin said Air Selangor's river surveillance team is now in Pahang to assist the Pahang Water Resource Authority and Pahang Department of Environment to identify the source of the pollution.
He added that water tankers will be sent to affected areas and critical premises such as hospitals and dialysis centres.
The Sungai Semenyih water treatment plant was shut down multiple times within a matter of days recently due to odour pollution, later identified to be from a nearby factory.
The incident deprived more than 300,000 accounts involving more than 1 million consumers of steady water supply for days.
