Air Selangor acting CEO Abbas Abdullah said water tankers and alternate water supplies will be sent to these premises and other affected areas.

A list of the affected areas may be found on Air Selangor’s official Instagram page, along with updates on the upgrading works at the Sungai Langat water treatment plant, scheduled to begin on Oct 10.

Water supply is expected to be restored in stages until full recovery on Oct 12.

Abbas said the maintenance works include the replacement of parts at the plant that have been used since 1973.

“The 16 main upgrading works will replace pumps and valves that have not been replaced since the plant began operations about 50 years ago.

“The works are being done to avoid unwanted incidents of unexpected water disruptions in the future,” he said.

He advised residents in the affected areas to store water ahead in advance.
