SHAH ALAM: The Sungai Langat and Cheras water treatment plants were temporarily shut down at 8.30pm and 10pm respectively last night due to odour pollution suspected to have originated from the Semantan river in Pahang.
Both plants receive raw water supply from the same river, said Air Selangor Group Corporate Communications head Amin Lin Abdullah.
In a statement released at 10am today, Amin said Air Selangor's river surveillance team has been in Pahang since last night to assist the Pahang Water Resource Authority and Pahang Department of Environment in identifying the source of pollution in the river.
"Water from the Sungai Langat dam was released into the river at 9.45pm last night as part of efforts to mitigate the odour pollution.
"(As a result of the shutdown), several areas in Kuala Lumpur and parts of Petaling and Hulu Langat will be experiencing temporary water interruption.
"Relief water supplies will be delivered by tankers to affected areas and critical public facilities, such as hospitals and dialysis centres," said Amin.
