Pengurusan Air Selangor Sdn Bhd (Air Selangor) said as of 6pm water supply had yet to be restored in only 21 areas in the Petaling district and two areas in Sepang.

“The duration of the water supply recovery varies from one area to another, depending on the location and distance of the consumers premises,” it said in a statement.

Air Selangor said water supply for areas affected by the disruption at the Bukit Tampoi water treatment plant was fully restored at noon today while areas affected by the disruption at the Sungai Semenyih water treatment plant are expected to be fully restored by 6am tomorrow.

Air Selangor advised consumers who have had their water supply restored to let the tap run until the water is clear before using it.

A total of 472 areas in five regions under Air Selangor experienced unscheduled water disruptions at 7am on Saturday when operations at the two water treatment plants were temporarily halted.
