Improvement works to be carried out by Pengurusan Air Selangor Sdn Bhd (Air Selangor) at the  Phase 1 Sungai Selangor Water Treatment Plant (LRA SSP1) on July 23 is necessary to avoid any damage that will have a greater impact on consumers.

Selangor Menteri Besar Amirudin Shari said the work has to be carried out by Air Selangor as the water assets were not properly maintained by the previous concessionaire.

"We understand the anxiety and inconvenience felt by consumers over the scheduled cut in water supply, but it has to be done to avoid damage that can result in a longer water supply disruption,” he told reporters.

Air Selangor, in a statement, said that 758 areas in Petaling, Klang, Shah Alam, Gombak, Kuala Lumpur, Hulu Selangor, Kuala Selangor and Kuala Langat will be affected by the scheduled water supply disruption of between 36 and 84 hours beginning July 23 due to improvement works at LRA SSP1.
