MMC calls for Metro Manila drainage system overhaul

San Juan City Mayor Francis Zamora, who also heads the Metro Manila Council (MMC), called for a comprehensive reevaluation of the capital region's drainage system, citing its age and inadequacy in addressing persistent flooding.

The MMC stated that the drainage system in Metro Manila is old and needs to be studied to craft a master plan that can handle the population, current volume of rain, climate change, and garbage problems.

According to Department of the Interior and Local Government Secretary Jonvic Remulla, each person in Metro Manila generates approximately one kilogram of trash daily, leading to 15 million kilograms of trash daily.

Much of this waste ends up clogging rivers, creeks, and drainage systems, exacerbating flooding in the region.

The MMC also pointed out that some drainage systems have been built over with houses and other structures, emphasizing the need for a complete inventory of all drainage systems.

Last week, the Metropolitan Manila Development Authority reported over 500 flood incidents across Metro Manila within a 24-hour period due to heavy monsoon rains and a low-pressure area.
