Metro Manila is expected to experience less severe flooding this rainy season following intensified drainage improvement and cleanup operations implemented by the Department of Public Works and Highways (DPWH).
According to DPWH Secretary Manuel M. Bonoan, the department has completed several flood mitigation projects in critical low-lying areas in the region.
He said rehabilitation of more than 30 pumping stations is ongoing, alongside continuous dredging, desilting, and clearing of major waterways and esteros to strengthen flood control measures.
“There are over 30 pumping stations in Metro Manila, and most of what we are doing is actually to increase their capacity because some are already old, but they can still run,” Bonoan explained.
The upgrades aim to boost the efficiency of existing facilities in managing heavy rains.
Regular cleanup drives in flood-prone esteros continue to prevent blockages and minimize the impact of flooding on densely populated communities.
Bonoan expressed confidence that these interventions will allow for quicker drainage and significantly reduce flood intensity compared to previous years, even during peak rainfall periods.
