KUALA LUMPUR: Pengurusan Air Selangor Sdn Bhd (Air Selangor) said water supply has been fully restored at all areas affected by the odour pollution incident in Sungai Semenyih which began on Dec 21.
In a statement at 7am today, Air Selangor said the supply was restored beginning last night.
Air Selangor also extended its apology to all users affected by the unscheduled water disruption. The company expressed its appreciation to the public for their cooperation during the crisis.
Earlier, it was reported that over 1.5 million users in four districts in Hulu Langat, Sepang, Kuala Langat and Petaling had experienced a water supply disruption as the Sungai Semenyih water treatment plant was shut down.
This followed an odour pollution incident in Sungai Semenyih, which was the main source of the plant’s raw water on Dec 21.
The source of contamination was traced to a sewage treatment facility in Bandar Bukit Mahkota.
On Dec 21, Air Selangor said the water treatment plant’s shutdown led to 328,957 user accounts in 348 areas in Petaling, Hulu Langat, Kuala Langat and Sepang being affected by the large-scale unscheduled water disruption.
Air Selangor operates as the sole concessionaire to manage water supply services in Selangor, Kuala Lumpur, and Putrajaya beginning April 1, this year.
Its operation is being monitored by National Water Services Commission (SPAN) under the Water Services Industry Act 2006.
On Dec 22, SPAN said the dumping of industrial waste into Indah Water Konsortium’s (IWK) manholes in Bandar Bukit Mahkota was the cause of the odour pollution.
On the same day, Selangor Environment, Green Technology and Consumer Affairs Committee chairman Hee Loy Sian was reported as saying that 20 IWK sewage manholes in the area would be sealed to prevent a recurrence.
Hee said he had instructed the Kajang Municipal Council and IWK to guard the entrance to monitor those entering and leaving the area.
"We have asked the police to conduct patrols to stop irresponsible parties from dumping chemical waste into the manholes,” he had said when met at IWK’s facility in Bandar Bukit Mahkota.
He also said closed-circuit television cameras would also be installed.
