Damaged Dike and Navigational Gate Trigger Severe Flooding in Malabon

Metro Manila— A damaged dike in Barangay Tonsuya and a broken navigational gate along the Malabon-Navotas River have worsened flooding in Malabon, as high tides continue to threaten low-lying areas despite the full operation of the city’s 40 pumping stations.

The structural damage, reported over the weekend, allowed seawater to pour into residential zones during peak tide levels. This compromised flood barrier, combined with heavy monsoon rains, led to widespread inundation in several barangays, catching many residents off guard.

While Malabon City Mayor Jeannie Sandoval reassured the public that all 40 of the city’s pumping stations are operational 24/7, she acknowledged that infrastructure failures, particularly the compromised dike and gate, have made flood control more challenging. “We are maximizing all available flood mitigation systems, but structural damage and extreme tide levels are a challenge,” Sandoval said.

In neighboring Navotas, the local government responded by issuing real-time flood and traffic advisories, rerouting vehicles, and cautioning residents in flood-prone zones. Some streets became impassable as high tide peaked at nearly two meters.

To assist affected commuters, the MMDA and local LGUs provided free rides, especially in stranded areas. This emergency initiative aimed to ease the mobility burden as floodwaters paralyzed public transportation.

Despite active pumping operations, Malabon and Navotas remain vulnerable due to aging flood infrastructure and external climate-related pressures. Officials are now urging national agencies to expedite repairs on the dike and navigational gate while reinforcing long-term coastal defense systems.

Residents are advised to remain vigilant, follow local advisories, and prepare for continued high tides and rainfall in the coming days.
