Sg Semenyih Water Treatment Plant replacement works to cost millions


Pengurusan Air Selangor Sdn Bhd (Air Selangor) has allocated millions for critical equipment replacement works at the Sungai Semenyih Water Treatment Plant (WTP).

The works, which will begin on Oct 9 by Syarikat Bekalan Air Selangor Sdn Bhd, will result in a plant shutdown.

Air Selangor distribution head Kelvin Siew Weng Hoe said the exercise has been planned for a long time.

“The works cost roughly around millions and we have no choice but to go forward with the works to ensure that supply is continuous for the people.

“With the planned optimisation exercise, we hope everyone will have access to water,” he said at the media briefing for the replacement works yesterday in Kuala Lumpur.

He said the replacement works, which focus on the bulk supply rate electromagnetic flow metres at the plant’s line 1, 2, 3, 4 and 5, are part of the company’s programme to decrease its non-revenue water (NRW).

“Considering the metres that we are using currently are over 20 years old, we want to replace them to get more specific measurements of water leaving the plant, as well as to reduce the amount of treated water lost along the distribution system,” he said.

Last year, the company invested RM193.6 million in various programmes to reduce NRW, which registered at 30.1% last year.

He expects no major other works for the Sungai Semenyih WTP for the rest of the year.

“We have already grouped other smaller projects with this shutdown. Therefore, going forward there should not be any further supply interruption,” he said.

The areas affected by the replacement works are Petaling, Hulu Langat, Sepang and Kuala Langat with their supply interruption period ranging from 30 hours to 72 hours.

Siew said local service centres will be operating as soon as the supply interruption begins for 24 hours to assist in enquiries and relief water supply.

“There will be three local service centres in Petaling, one in Hulu Langat, two in Sepang and one in Kuala Langat,” he said.

He added that 62 lorries carrying water tanks and 10 jumbo tankers will be moving within the affected areas throughout the interruption period.

Customers affected by the interruption can check their water supply status on all of Air Selangor official communication channels such as its Facebook page, Twitter at

Last year, Air Selangor’s works primarily included aged pipes replacement of as long as 178.55km.

The company invested RM391.6 million in capital works projects such as pipe replacement, construction and WTP upgrades, as well as distribution systems.
