Ranhill SAJ chief operating officer Khairul Effendy Tusam said the incident was unexpected and rare, with the company’s team facing various challenges throughout the repair process.

“We understand the inconvenience this caused to our customers.

“From the moment this incident occurred, every effort has been made to restore water supply as quickly as possible to all affected areas,” he said in a statement today.

He added that a thorough investigation is currently under way to determine the root cause of the incident.

“The investigation involves a thorough examination of every technical aspect, including the regular maintenance of all equipment in the processing system and water pipelines at the affected plant.

“All data collected will be carefully reviewed to update existing procedures and prevent similar incidents from occurring in the future.”

He also expressed his appreciation to the affected consumers for their patience and cooperation during this challenging period.

On Wednesday, state public works, transport and infrastructure committee chairman Fazli Salleh said the damaged pumps at the Sungai Johor water treatment plant had forced the plant to cease operations.

He said the disruption meant that 318 million litres of water could not be supplied to nearly 100,000 consumer accounts in several areas.
