Managing water flow across state boundaries can no longer be done in isolation. With 3 out of every 10 Malaysians residing in Selangor and Kuala Lumpur, a region driving 41.7% of the national economy, the Selangor state government and the Federal Territories Department have officially unified their flood mitigation strategy.
In a joint statement issued by Federal Territories Minister Hannah Yeoh and Selangor Menteri Besar Datuk Seri Amirudin Shari, both administrations agreed on a 5-point plan targeting land management, reservoir capacity, green spaces, sustainable urban development, and water flow.
Quick Read TL;DR — The 5 Joint Flood Mitigation Actions Technical Taskforce: A joint technical team will meet within 2 weeks to outline project locations, scope, costs, and funding ahead of the upcoming Parliament session and Budget 2027 tabling. Dam Capacity Studies: Evaluation of Batu Dam and Klang Gates Dam to determine whether current retention capacity meets water management needs for the next 20 to 30 years. New Upstream Ponds: Technical agencies will scout suitable upstream locations, primarily in Selangor, to construct brand-new flood retention ponds. Existing Pond Upgrades: Selangor JPS identified 3 ponds for expansion, Kampung Laksamana, Sungai Kertas, and Bukit Lagong (which requires forest reserve degazettement). River Dredging & Silt Site: Synchronized desilting across KL and Selangor rivers, backed by a dedicated 30-acre sediment disposal site in Selangor identified by KL JPS.Aligning Cross-Border Water Flow
Because water flows from Hulu Selangor through Kuala Lumpur before reaching southern zones, both leaders emphasized that drainage cannot be managed in silos. A technical meeting will convene within two weeks to outline exact costs, funding sources, and implementation timelines. Preliminary findings will be submitted prior to the upcoming Parliamentary sitting and the tabling of Budget 2027.

📊 Why Cross-Border Action MattersTogether, Selangor and Kuala Lumpur account for 30% of Malaysia's total population and contribute 41.7% to the national GDP. Unifying drainage strategy protects both lives and the national economy.
Long-Term Dam Studies & Retention Upgrades
Beyond immediate desilting, engineers will assess whether the Batu Dam and Klang Gates Dam can withstand regional rainfall demands for the next 2 to 3 decades.
Upgrading the Bukit Lagong retention pond will require part of the local forest reserve to be degazetted before structural construction and expansion work can begin.
Concurrently, three existing retention ponds in Selangor, Kampung Laksamana, Sungai Kertas, and Bukit Lagong, have been slated for capacity expansion. Expanding the Bukit Lagong facility will require degazetting a portion of its surrounding forest reserve land. To support ongoing desilting works, Kuala Lumpur JPS is securing a 30-acre dedicated sediment disposal site within Selangor to manage dredged materials safely.
