Selangor DID Deploys 150 Pumps, Intensifies Efforts to Reduce Flood Risks
SHAH ALAM: The Selangor Department of Irrigation and Drainage (DID) is intensifying efforts to reduce flood risks through the implementation of Flood Mitigation Plan (RTB) projects, river dredging works and drainage system improvements in flood-prone areas.
Selangor DID said the measures include monitoring pump operations along Sungai Langat, particularly in the Bukit Changgang flood mitigation area, to ensure that water levels within the internal drainage system can be gradually lowered.
“The Kuala Langat District DID is also operating a mobile pump with a capacity of 20 cubic feet per second (cusecs) and a screw pump at the Bukit Changgang flood mitigation area to accelerate water discharge and control river water levels,” it said.
Selangor DID said river dredging works were also being carried out under the Sungai Damansara Flood Mitigation Plan to increase the river’s capacity and reduce the risk of overflowing.
“Quick-win measures in Kampung Melayu Subang involve dredging Sungai Pelempas, increasing pumping capacity at Jalan Resak from 140 to 280 litres per second and installing a flap gate, while the pump at Jalan Ikhlas has a capacity of 280 litres per second.
“In addition, the Kuala Selangor District DID has taken action to close two water passages beneath the LATAR Expressway to prevent water from Sungai Buloh from entering village areas,” it said.
Selangor DID reported that a total of 150 mobile pumps had been deployed across Selangor as of November 6, 2026, comprising 119 state-owned units and 31 federal units to strengthen preparedness in flood-prone locations.
“Klang district recorded the highest number of deployed pumps with 37 units, followed by Sabak Bernam with 24 units, Kuala Langat (23), Kuala Selangor and Petaling with 19 units each, Gombak (seven), Sepang (six) and Hulu Langat (one).
“Apart from the pumps deployed in the districts, another 14 units are located at the Selangor Mechanical and Electrical Management Division (BPME) storage facility, with four units on standby and 10 undergoing maintenance,” it said.
In a related development, a submersible hydraulic pump with a capacity of five cusecs, or 140 litres per second, has been installed at Jalan Paip, Klang, to reduce flood risks in residential areas.
“The installation was carried out by the Selangor DID Mechanical and Electrical Services Division (BPME) together with the Klang District DID, while operations and monitoring are managed by the Klang District DID.
“The Kuala Selangor District DID has also deployed an additional mobile pump at the Merbau Water Gate to accelerate the pumping of floodwater from village areas into Sungai Buloh,” it said.
