Air Selangor: Water supply to areas affected by unscheduled cut to resume in stages from midnight

Estimate Reading Time: 2 minutes

PETALING JAYA: Water supply to consumers in several districts in Selangor that have been hit by an unscheduled cut since Sunday (Oct 4) will resume in stages over the next three days, starting midnight Tuesday (Oct 6).


Pengurusan Air Selangor Sdn Bhd (Air Selangor) chief executive officer Suhaimi Kamaralzaman said supply resumption to the 274 affected areas would be staggered into three main stages.

“The first stage will see supply restored to 145 areas by 6pm Wednesday (Oct 7) while another 91 areas in the second stage will have their supply restored completely by 6pm on Oct 8.

“The third stage will involve 38 areas that will receive supply by 6pm on Oct 9,” he said.

Suhaimi said that the Sungai Semenyih water treatment plant had resumed operations Tuesday morning.

“The supply that will be distributed will go through a water quality test and must comply with the standards set by the Health Ministry,” he said during a press briefing at the Air Selangor headquarters in Bangsar on Tuesday.

The Sungai Semenyih and Bukit Tampoi water treatment plants stopped operating on Sunday after odour pollution was detected in Sungai Semenyih, which is the raw water source for both facilities.

This resulted in an unscheduled cut, affecting supply to some 310,000 user accounts involving 1.3 million consumers in Selangor involving the Petaling, Hulu Langat, Kuala Langat and Sepang district.


In a statement earlier Tuesday, Air Selangor said that the Sungai Semenyih water treatment plant had resumed operation after samples taken at its uptake recorded 0 TON (threshold odour number) three times in a row.

However, Suhaimi said that water at uptake of the Bukit Tampoi water treatment plant that served 15,000 accounts still recorded pollution of three TON.

He said Air Selangor yet was unable to provide details on when this would be resolved.

“But accounts whose supply is from the Bukit Tampoi plant would receive water from the Sungai Semenyih plant instead,” said Suhaimi.

Authorities had said that the waste found in a bush near the Nilai Industrial Area in Nilai, Negri Sembilan had caused the pollution which the odour matched that detected near the Semenyih water treatment plant.

Suhaimi declined to disclose the offender but urged the media to refer to the relevant ministry for details.

Meanwhile, responding to The Star’s front page story on Tuesday regarding the dirty-looking water that was supplied via a water tanker to Puchong Jaya residents, Suhaimi said the matter would be investigated.

The public is encouraged to visit Air Selangor’s social media sites or website at or download the Air Selangor application on their mobile devices for the latest updates and locations of alternative supply. -The Star
