Giant Wall of Marikina River

The Japan International Cooperation Agency (JICA) and Department of Public Works and Highways (DPWH) began this week the fourth phase of the Pasig-Marikina River Channel Improvement Project to mitigate extreme flooding in Metro Manila.A massive flood wall that will be built along the riverbanks.

JICA has assisted river channel improvement in the Pasig-Marikina River since 2000. The fourth phase will implement structures such as revetments, flood walls, and movable weirs that will help adjust and regulate the flow of the flood waters.

The gate structures that will be built under the project will help protect low-lying areas in Cainta and Taytay from backflow flooding.


In addition to structural measures, the project also includes soft measures such as Information Campaign and Publicity, by ensuring efficient and effective information dissemination in various forms of media for smooth coordination and implementation of the project. There is also the preparation of flood hazard map which is necessary for the promotion of flood evacuation activities by providing essential data to support the LGUs in formulating action plans concerning disaster risk reduction.

Flood control experts from the Department of Public Works and Highways (DPWH) and the Japan International Cooperation Agency (JICA) conducted an on-site inspection of proposed flood control infrastructures in the Middle and Upper Marikina River Basin.

These projects include the construction of modern dikes and ripraps at the Marikina River, which is also being widened to avert flooding in communities nearby. Water pumping stations are also being constructed along creeks and Marikina River.
