SHAH ALAM, Feb 8 — The Sungai Klang river rehabilitation, a vital component of Selangor’s water security strategy, is progressing steadily with a 5.9 per cent completion rate since its inception in November 2022, with the project expected to be completed as scheduled by 2028.
The figure also surpassed last year’s target of 5.8 per cent.
State executive councillor for public infrastructure Izham Hashim said while the project is advancing well, it has faced significant challenges due to the substantial volume of rubbish encountered during dredging operations.
“The material dredged up from Sungai Klang is 40 per cent rubbish, posing a significant obstacle to the process of deepening and widening of the river.
“Large items like tyres, furniture and plastic waste have impeded the dredger’s efficiency and disrupted daily operations,” he told the press during a site visit to the Alam Impian portion of the project, here, today.
The project encompasses a comprehensive two-part Integrated Water Resources Management (IWRM) exercise, namely the deepening and widening of 56km of Sungai Klang to enhance the river’s capacity, and the reinforcement of soil embankments and bund constructions to mitigate flood risks and improve water quality.
Izham said the state government plans to install log booms at all mini estuaries leading to Sungai Klang to prevent further trash from entering the river and potentially hindering the dredging process.
Efforts will be augmented by introducing another cutter suction dredger, specially retrofitted to manage the debris effectively.
“At the same time, the state government will also meet with Kuala Lumpur City Hall to discuss the river pollution mitigation process within its borders because some of the trash is from upstream, within their jurisdiction,” he added.
The IWRM project is segregated into twelve zones within four main blocks along the 56km Sungai Klang, with some of them marked as being the most vulnerable to potential flooding due to its shallow depth caused by decades of sediment build-up.
Izham revealed that initial dredging operations in Block 3, Zone 8 (upstream Taman Sri Muda) have so far resulted in the removal of 130,000 cubic metres of material.
He added that dredging work will expand into Zones 6 and 7 within Block 3 in mid-February, before moving to Block 1 (Zones 1 and 2 within the Port Klang area) by early July 2024.
Izham also noted that the IWRM project, an initiative under the state government, will align with other flood mitigation projects along Sungai Klang initiated by the Federal government.
The project consists of three key engineering components — design (hydrology and hydraulic analysis), bund improvement and slope protection work, including flood wall requirements, construction, and subsequent maintenance.
IWRN, which is a special project done by Menteri Besar Selangor (Incorporated), or MBI, through its subsidiary Landasan Lumayan Sdn Bhd, is also part of the state’s high impact initiative dubbed the Selangor Maritime Gateway special economic zone.
The project aims to enhance water security and effective water resource management, with the ultimate goal of increasing Sungai Klang’s capacity by 40 per cent upon completion.
