Garbage Clogs Drainage Causing Metro Manila Flooding
The Metropolitan Manila Development Authority (MMDA) has pointed to garbage as a major cause of flooding in parts of Metro Manila. The agency urges the public to exercise discipline in managing their waste to help ease the problem.
MMDA Chair Don Artes highlighted this issue during a recent government press briefing. He explained that heavy rains driven by the southwest monsoon, combined with blocked drainage systems, have worsened flooding in several areas.
Drainage Systems Overwhelmed by Trash
Artes revealed that the drainage infrastructure in Metro Manila is outdated, some parts being over 50 years old. This aging system struggles to handle current water volumes, especially when clogged with bulky garbage like sofas and refrigerators.
“Our drainage system is already small and outdated—it’s more than 50 years old. On top of that, it gets clogged with this kind of garbage,” Artes stated in Filipino. He emphasized that such blockages make it hard for floodwaters to drain away quickly.
Flood-Prone Streets Linked to Garbage Blockage
The MMDA has identified 49 flood-prone streets in Metro Manila, where garbage buildup is the main cause of flooding. For instance, on White Plains Avenue in Quezon City, MMDA crews had to clear canals filled with trash to allow floodwaters to recede.
“So, that shows us that if there hadn’t been any garbage, flooding shouldn’t have happened in that area,” Artes said.
Shared Responsibility for Flood Prevention
Artes stressed that solving flooding is not solely the government’s task. He called on all citizens to take responsibility, especially in proper waste disposal.
“We all need to work together. The government cannot solve this alone. Everyone’s participation is necessary—especially when it comes to proper waste disposal,” he added in Filipino.
Weather Systems Worsen Flooding
Metro Manila and neighboring provinces have faced continuous heavy rains due to the southwest monsoon and weather disturbances such as Tropical Storm Crising. These conditions have caused widespread flooding, stranding commuters and prompting class and work suspensions.
The MMDA’s call for disciplined waste management comes as a crucial step toward reducing flood risks. Proper disposal can help keep drainage systems clear and improve the city’s resilience against heavy rains.
