The Upper Wawa Dam in Rodriguez, Rizal, is a vital infrastructure project set for completion by 2025. Part of the Wawa Bulk Water Supply Project, it will deliver 518 million liters of water daily and regulate flooding in Rizal, Marikina, Cainta, and Metro Manila. Beyond water and flood control, the Upper Wawa Dam strengthens disaster resilience, supports sustainable development, and boosts long-term confidence in Rizal’s future growth.

A blocked Tullahan River could trigger severe flooding, disrupt bus and rail services, and delay key infrastructure from La Mesa Dam to Manila Bay. Spanning Malabon, Caloocan, Valenzuela, and Navotas, this vital waterway supports flood control and transport reliability. Keeping it clear is critical to protect communities, maintain transit access, and ensure Metro Manila’s infrastructure growth remains sustainable and resilient.
