How could the culvert construction beneath a railway line affect the Klang Valley?
Flood mitigation infrastructure could improve regional resilience in the Klang Valley. The construction of an RM18mil cross-drainage culvert in Ampang Jaya is designed to manage surface run-off and address recurring floods in the area. This project channels surface run-off from Taman Melawis into a 1,000cu metre concrete tank before controlled release. As part of a larger effort involving 255 short-term flood mitigation projects across Selangor, this localized infrastructure upgrade contributes to the overall resilience and reduced flood risk across the wider Klang Valley region.

How it reaches Klang Valley
-
Construction of an RM18 million cross-drainage culvert beneath the KTM railway line in Klang began on October 1, 2026, and is scheduled for completion by late November. The project is designed to manage surface run-off during heavy rainfall by channeling water into a 1,000 cubic metre concrete tank before release.

Why it matters
Urban areas like the Klang Valley face significant risks from recurring flash floods, which can disrupt operations, damage infrastructure, and impact economic stability. Flood mitigation projects, such as this culvert, are critical investments aimed at reducing these localized risks and enhancing the overall safety and functionality of the region.
This specific project is part of a much larger, multi-agency effort involving the Drainage and Irrigation Department, local authorities, and the Public Works Department. This broader initiative includes medium- and long-term works backed by substantial funding, with RM4bil provided by the Federal Government and up to RM600mil from the state government.
What we don't know yet
- What is the projected reduction in flood incidents due to the completion of these short-term projects?
- How will the ongoing medium- and long-term projects affect the overall flood risk profile of the Klang Valley?
