SHAH ALAM, Nov 10 — Nine areas in Kuala Selangor are being prioritised for flood mitigation measures, including drainage maintenance, pump operations, and retention pond repairs, alongside plans for long-term flood mitigation projects.
The Selangor Irrigation and Drainage Department (JPS) said the district recorded the highest number of affected locations, with nine of the 15 areas across four districts impacted by very heavy rain from Thursday (November 5) to Saturday (November 7).
Rainfall readings of between 51.5mm and 114.5mm also affected four areas in Klang and one each in Petaling and Sepang.
“Very heavy rainfall over a short period was identified as resulting from several factors, including high rainfall intensity, river overflow, inadequate internal drainage capacity to accommodate surface runoff, low and narrow bridges, as well as external factors such as irresponsible parties damaging the levels of existing river embankments,” it said in a statement yesterday.
In Kuala Selangor, the affected areas identified were Taman Perumahan Seri Alam, Mapel Hillpark, Kampung Bukit Hijau, Kampung Bukit Kuching Tengah, Saujana Perdana, Batu 7 Kampung Ijok, Kampung Jaya Setia, Kampung Bukit Kerayong, and Kampung Parit Mahang.
At Taman Seri Alam, immediate measures include operating the pump house by the Kuala Selangor Municipal Council (MPKS), installing mobile pumps by JPS, and repairing the existing flood retention pond by the developer.
The project to upgrade the drainage system in the Saujana Utama residential area is expected to go to tender next month, while the Seri Alam drainage project is scheduled for tender in the second quarter of 2027.
At Mapel Hillpark, JPS is maintaining the existing flood retention pond and carrying out repair works on the Palma Hillpark Flood Retention Pond.
Meanwhile, maintenance of the main drainage system and the operation of several screw pumps are continuing in Kampung Bukit Hijau to help reduce the risk of water overflow. A project to upgrade the drainage system in the area is planned, with land acquisition scheduled for 2027 and the tender process expected in 2028.
Long-term measures also include a proposal by West Coast Expressway (WCE) to build a linear water retention system, as well as plans by IJM Land to increase the capacity of its retention pond.
At Batu 7 Kampung Ijok, immediate action includes operating screw pumps and mobile pumps, ongoing repairs, and raising the Sungai Buloh embankment. The Sungai Buloh Flood Mitigation Plan (RTB) Phase Two project is still at the design preparation stage.
In Kampung Jaya Setia, drain maintenance is underway, while the drainage system upgrade project is expected to go to tender in the first quarter of 2027.
At Jalan Bahagia, Kampung Parit Mahang, drain and drainage system maintenance for Sungai Janggut and Sungai Sembilang is continuing, alongside the operation of the Parit Gajah screw pump.
Long-term measures also include a Public Works Department (JKR) proposal to raise the level of Jalan Bahagia.
For Kampung Bukit Kerayong, the main drainage system is maintained regularly, while the proposed Sungai Sembilang and Sungai Janggut Basin RTB remains at the application stage.
Two other locations receiving attention are Kampung Bukit Kuching Tengah and Saujana Perdana, where drainage maintenance and pump operations are being carried out to help reduce water overflow.
The Selangor JPS said the short- and long-term measures were among the efforts by the federal and state governments to address flooding in affected areas.
“The federal and state governments are always attentive to every flood incident. Nevertheless, flood risks cannot be eliminated entirely due to low-lying terrain and extreme weather caused by climate change,” it said.
Members of the public can check project updates through the Selangor JPS Flood Mitigation Project Dashboard, which is updated by the 10th of each month.
