CONSTRUCTION work on the intake component for the Sungai Rasau Water Treatment Plant (WTP) project at Taman Mas in Puchong, Selangor, is set to restart this month.
The project was halted due to an embankment collapse on Sept 7, 2024, prompting a stop-work order to assess the situation and implement additional safety measures.
This order has now been lifted, according to Selangor infrastructure and agriculture committee chairman Datuk Izham Hashim.
He said the contractor was currently engaged in preliminary works, with mobilisation proceeding in phases.
“An independent consultant appointed by Air Selangor has completed the review on the repair works and the proposed new design for the collapsed embankment at the Sungai Rasau WTP intake, as submitted by the contractor,” he said at the Selangor State Assembly sitting at Bangunan Dewan Negeri Selangor in Shah Alam.
The design improvements include the implementation of a cellular cofferdam or double wall, where the space between the walls will be filled with sand.
Additionally, he said the project would utilise the latest design innovations, including a more robust “flat web sheet pile”, a technology imported from Japan.
He added that works were expected to be completed by January next year.
Izham said this in reply to Datuk Dr Ahmad Yunus Hairi (PN-Sijangkang) who asked when the project would resume.
According to Air Selangor, the Sungai Rasau WTP is part of the RM3.4bil allocated for the first out of two stages of the Rasau Water Supply Scheme that was expected to become Malaysia’s largest and most advanced water treatment facility.
Stage 1 would have the capacity to produce 700 million litres of clean water daily by the end of next year.
It will substantially reduce risk from river pollution, provide flood mitigation and support growing demand, including from industrial and technology sectors.
It would encompass nine former tin mining ponds covering 489ha, serving as the country’s first dual-function off-river storage system.
When completed, it will be capable of supplying water and mitigating floods, including in flood-prone areas of Taman Sri Muda, Shah Alam.
Stage 2 will begin development in 2027 and is expected to be fully completed by 2030.
