Manila: The Metropolitan Manila Development Authority (MMDA) announced that floodwaters in the National Capital Region are now receding more quickly than in the past, highlighting effective flood mitigation strategies.

According to Philippines News Agency, MMDA General Manager Undersecretary Nicolas Torre III, during an interview with Radyo Pilipinas, used the intersection of Aurora Boulevard and Katipunan Avenue in Quezon City as a case in point. Floodwaters that once took 18 to 24 hours to drain now clear in approximately five hours. "Nitong nakaraang pag-ulan na umapaw 'yan, 2 p.m. tumigil ang ulan, 7 p.m. passable na uli ang kalsada sapagkat wala na 'yong tubig," Torre explained, emphasizing the rapid improvement.

The MMDA evaluates the success of its flood control measures using three criteria: the extent of flooding, the depth of standing water, and the speed at which floodwaters recede. Torre mentioned that areas like Camanava (Caloocan, Malabon, Navotas, Valenzuela) have also seen positive changes, as confirmed by local government assessments.

Torre credited the progress to the MMDA's collaboration with other agencies, notably the Department of Public Works and Highways (DPWH). They have been working together to inspect the design of existing waterways, drainage systems, and pumping stations to ensure effective water channeling towards major waterways, Manila Bay, and Laguna Lake.

During a recent Metro Manila Council meeting, the MMDA, DPWH, and local government officials reviewed the region's drainage master plan. Their goal was to synchronize improvements and flood mitigation measures across Metro Manila. DPWH Secretary Vince Dizon called for a reassessment of the drainage master plan, acknowledging that many current systems are outdated and may require expansion, along with the addition of new pumping stations where needed.

San Juan City Mayor and Metro Manila Council Chairperson Francis Zamora, speaking on the same radio program, highlighted the necessity of coordinating local solid waste management efforts. He noted that upgraded drainage systems and pumping stations would be ineffective if clogged with garbage. Zamora urged residents to exercise more discipline in waste disposal and to cease using rivers, creeks, and waterways as dumping grounds.
