PETALING JAYA: Traces of diesel were detected near the Cheras Batu 11, Hulu Langat water treatment plant (WTP) on Tuesday (April 9) but there was no supply disruption, says Selangor public health and environment committee chairman Jamaliah Jamaluddin.
She said the Selangor Water Management Board (Luas) investigated the incident and believed the source was a nearby industrial area.
"LUAS immediately activated preventive measures by placing oil pads and two bags (50 kg) of activated carbon to trap and prevent the flow of oil into Sungai Langat," she said in a statement on Wednesday (April 10).
It also appointed a contractor to clean up any traces of diesel and the work was finished at 9.40pm, she added.
She said Luas was monitoring the situation and checked for any potential effects of pollution every 30 minutes.
The site of the pollution is about 400m from the water treatment plant.
"Luas' investigation did not (identify) any cause for the oil leakage.
"Further checks showed remnants of diesel near premises at the industrial area, which could be the site of a car wash," she added.
There was no disruption of water supply to consumers, Jamaliah said.
"The people should be vigilant against any source of water pollution and report to LUAS if there is any suspicious activity to ensure that the water treatment plant continues operating and there is no supply disruption," she added.
