SHAH ALAM: The source of odour pollution that caused the shutdown of the Sungai Semenyih water treatment plant this morning has been roughly pinpointed as Nilai in Negri Sembilan, the Selangor state government has confirmed.
Selangor executive councillor for Tourism, Environment, Green Technology and Consumer Affairs Elizabeth Wong said upstream waterways in Nilai were found to have an unusually strong odour as they flow into Sungai Buah, which leads to the Semenyih intake point.
"Dead fish have also been sighted in the area. River surveillance teams from Pengurusan Air Selangor Sdn Bhd (Air Selangor) and the Selangor Water Management Board (Luas) were deployed this morning to narrow down the source of the odour.
“This afternoon, the teams were joined by a unit from the National Water Services Commission (SPAN)’s central office.
"As of 4pm, the odour at Nilai is still evident, and all efforts are ongoing to pinpoint the contributing source. We have conveyed information to the Negri Sembilan Department of Environment (DoE) through the Selangor DoE and Luas," said Wong in a statement today.
Several areas in the Petaling, Hulu Langat, Kuala Langat and Sepang districts are experiencing water disruptions following the closure of the Sungai Semenyih water treatment plant at 7.30am today.
In the Hulu Langat district, the affected areas are Bangi, Bandar Bukit Mahkota, Kajang, Semenyih and Rinching.
In the Kuala Langat district, the areas are Morib, Banting, Bandar Saujana Putra, Bandar Rimbayu and Telok Panglima Garang.
