Part of Flooding and severe weather caused infrastructure damage in the Cordillera Administrative Region and Calabarzon, prompting a response from DPWH on August 1, 2026.

How could the DPWH flood control rehabilitation in Calumpit affect the Pampanga River?

Possible What happens if… A possibility worth considering, not a forecast.

New flood defenses may regulate Pampanga River's impact on Calumpit The Department of Public Works and Highways is undertaking a rehabilitation of flood control structures in Calumpit, which is situated along the Pampanga River. This project involves strengthening and raising existing defenses, with new structures built more than 1.5 meters above the highest historical river level. The goal is to provide a greater buffer against rising water and prevent flooding from entering nearby communities like Bulusan, Calizon, and Frances. Furthermore, the DPWH stressed that waterways must be given sufficient space, advocating for the widening of the river in certain areas rather than constricting its natural course.

The facts so far

As reported. Each one links to where it comes from.

  • The rehabilitation project covers nearly 1.8-kilometer flood control structures in Calumpit.manilatimes.net
  • The new structures were raised more than 1.5 meters above the highest historical river level.manilatimes.net
  • The project is intended to correct deficiencies in structures that were previously almost level with the river's high-water mark.manilatimes.net
  • The DPWH stressed the need to widen the river in certain areas rather than constrict its natural course.manilatimes.net

Why it matters

The primary stake for Calumpit and the surrounding communities is the mitigation of recurring flooding, which has repeatedly affected villages like Bulusan, Calizon, and Frances. The failure of previous flood defenses, which were described as too low and lacking adequate reinforcement, led to residents experiencing problems during high tides and heavy rains. The successful completion of this project, which is currently 75 percent complete, is seen as a critical step in protecting the municipality's residents and infrastructure.

This intervention is part of a broader government focus on addressing flooding in Calumpit, which has been subject to controversy over allegedly anomalous flood control projects. The DPWH is simultaneously pursuing accountability for those responsible for defective or overpriced projects, indicating that the infrastructure repair is being carried out under strict governmental oversight to ensure the long-term integrity and benefit of the structures.

What we don't know yet

  • Will the planned widening of the river in certain areas be implemented as part of the project?
  • How will the new structures perform during extreme weather events beyond the highest historical river level?

What would change this answer

The DPWH successfully completes the project by January or February next year.The immediate risk of flooding in the affected villages should decrease significantly, validating the structural changes.
The local government and DPWH district engineering office fail to coordinate the initial deployment of mobile pumps.The ability of communities to manage water during heavy rains will be hampered, even with improved defenses.
