CLEANUP, dredging and desilting of major waterways across the country will continue during Holy Week as part of the government's bid to move to prevent flooding, the Department of Public Works and Highways (DPWH) said.
DPWH Secretary Vince Dizon said on Wednesday that despite the holiday period, field teams remain deployed in key areas, carrying out around-the-clock clearing of waterways clogged by silt, debris and waste.
He said these operations aim to restore water flow, increase the carrying capacity of waterways, and prevent overflow during heavy rains.
"From Luzon to Mindanao, crews are clearing rivers, esteros, and drainage systems of silt, debris and waste, restoring water flow and boosting capacity to handle heavy rains," Dizon added.
The intensified efforts form part of the expanded Oplan Kontra Baha program, in line with the president’s directive to strengthen flood mitigation measures nationwide.
He added that by sustaining operations even during Holy Week, authorities are working to stay ahead of the expected onset of the wet season and minimize disruptions to communities.
Dredging and desilting activities are underway in high-risk and flood-prone areas, including Metro Manila, Ilocos, and Cagayan Valley; Naga, Cebu, and Bacolod; and Maguindanao. These locations were identified based on vulnerability to flooding, historical data, and sediment buildup that restricts water flow.
In urban centers such as Metro Manila, clearing operations also target drainage systems often blocked by solid waste, contributing to flash floods during sudden downpours.
Dizon said the simultaneous nationwide clearing of waterways reflects a more proactive, preventive approach to disaster risk reduction — focusing not just on response, but on preparedness and mitigation.
The ongoing work, he said, also highlights the importance of interagency coordination and community participation.
The DPWH chief urged residents to support the initiative by practicing proper waste disposal and helping keep waterways clear, as even small blockages can significantly affect drainage efficiency.
"With the rainy season fast approaching, sustained, large-scale efforts like these are critical to protecting lives, safeguarding infrastructure, and reducing the economic impact of flooding across the country," Dizon stressed.
Last Jan. 14, Dizon signed a special order creating a task force for Oplan Kontra Baha, headed by Undersecretary for Special Concerns Charles Calima Jr. The same task force was replicated in all 177 DPWH regional offices nationwide.
The Task Force Kontra Baha will coordinate with the Metropolitan Manila Development Authority, Department of Environment and Natural Resources, Department of the Interior and Local Government, and private sector.
Dizon gave the task force six months, or until July, to finish its mission and thereafter submit an accomplishment report detailing improvements, challenges, solutions, resources consumed, and targets achieved.
