The raw water treatment process in Sungai Langat Water Treatment Plant, which was affected following a mechanical filtering equipment (band screen) issue, has resumed operations and treated water distribution to the distribution reservoir is back to normal.

In a statement, Syarikat Bekalan Air Selangor Sdn Bhd (Syabas) said it was now in the process of stabilising pressure and flow in the distribution system to expedite supply restoration.

"Based on our on-site monitoring as at noon today, the effect of interruption has been reduced and water supply in most areas has been restored," said the statement issued by Abdul Raof Ahmad, who heads Pengurusan Air Selangor Sdn Bhd's Customer Relationship and Communication Department.

The affected areas in Kuala Lumpur have achieved an 89% restoration rate, with three areas, namely Pandan Prima, part of Taman U-Thant and Taman Tenaga, having been fully restored.

Petaling and Hulu Langat recorded a 100% and 65% restoration rate, respectively.

"To reduce the impact of interruption, assistance via water tankers is continuously mobilised," said Syabas, a member of the Air Selangor Group.
