KUALA SELANGOR, May 27 — The scheduled upgrading and maintenance works for critical assets in the Sungai Selangor Phase One (SSP1) Water Treatment Plant (WTP) from June 5 to June 7 are necessary as the assets are over 30 years old.
State executive councillor for infrastructure and agriculture Izham Hashim said maintenance is necessary since certain critical components require replacement and maintenance.
They include two valves (each sized at 1,350 and 1,450 millimetres) at the Matang Pagar WTP, as these valves have been in continuous use since the 1990s, operating 24 hours a day.

Replacing these valves is essential to ensure the continued functionality of the SSP1 WTP. Additionally, maintenance work will also be carried out on the 6.6 and 33-kilovolt switchgear at the SSP1 WTP’s pump house to meet the requirements set by the Energy Commission.
The replacement and maintenance costs for these components are estimated to be around RM500,000. To minimise disruption to the water supply, the authorities have carefully planned the replacement schedule.
Though the SSP1 WTP will be temporarily closed during the replacement process, efforts will be made to minimise the impact on water availability.
“We are continuously carrying out technical audits on assets at the treatment plant to ensure when such assets will require maintenance or upgrading. Since the treatment plant is old, we must continue to carry out maintenance and upgrading before the situation becomes serious.
“As many may be aware, we had decided to postpone the scheduled maintenance due to the festive and other related festivals…after much consideration, carrying out the maintenance and upgrading early next month has been identified as a good time,” he said during a press conference after visiting the SSP1 WTP today.
Izham added that the state government is also taking initiatives to complete the Sungai Rasau WTP project to avoid water disruption in Selangor if major maintenance work is needed in the future.
Earlier, Pengurusan Air Selangor Sdn Bhd (Air Selangor) said the closure of the SSP1 WTP will affect seven regions — Kuala Selangor, Gombak, Petaling, Kuala Lumpur, Hulu Selangor, Klang, and Shah Alam.
Consumers can expect water supply to resume in stages from 3am on June 6, after maintenance work is completed.
