MANILA, Philippines — The Department of Public Works and Highways (DPWH) is evaluating the integration of concrete and eco-friendly features in flood management infrastructure across high-risk communities in Pampanga and Bulacan.
Public Works Secretary Vince Dizon disclosed on Wednesday that the agency is reviewing the application of hybrid designs for upcoming flood defense initiatives.
“I think we need to take a broader look at how things are being done elsewhere. Let’s look at countries that have already successfully implemented this,” Dizon remarked during an interview following a collaborative meeting with DPWH personnel, Haskoning Phils. Inc., and Project NOAH at the DPWH Central Office.
“They’ve already gone through the process…as was mentioned earlier, they used to rely heavily on concrete — it was all concrete. But in some cases, they are actually tearing down those concrete structures. They are shifting toward more nature-based solutions,” he explained.
However, the Cabinet official clarified that a balanced approach is essential, as certain conditions still demand traditional civil engineering solutions.
“Not everything can be nature-based, though. There are instances where concrete is truly necessary,” he stated.
“But we need to study this carefully and learn from those who have the expertise and have done it right, so we don’t end up wasting money again,” Dizon added.
The public works chief specified that initial planning centers on low-lying municipalities in Northern Luzon situated along the upper coast of Manila Bay.
“So our focus right now is the North Manila Bay towns — Hagonoy, Paombong, parts of Malolos (Bulacan); Macabebe, Masantol, Sasmuan (Pampanga),” Dizon said.
