Now in Phase IV, it's a multi-billion-peso effort to solve Metro Manila's severe flooding, backed by the Japan International Cooperation Agency (JICA). Here's the latest on this major flood control initiative: 🚧 Scope & Timeline · Budget: The cost ballooned to PHP 57.7 billion after design changes to handle climate change. · Schedule: River widening/revetment target 2028, key gate structures (Manggahan, Marikina) may extend to 2029–2030. · Target Depth: Dredging aims for depths of 20–23 meters and widths of 100–110 meters to boost capacity. 🛠️ Key Works & New Tech · Infrastructure: Installing dikes, floodgates, and culvert pipes (e.g., on Sumulong Highway). · Innovation: First use of Alloy Saving Duplex Stainless Steel (ASDS) for floodgates—lighter and more durable. · Current Focus: DPWH is fast-tracking drainage repairs and cleaning canals to ensure water flows fast into the river.
