The Wawa Bulk Water Supply project is an infrastructure flagship project of the Philippine government intended to address the water crisis in Metro Manila and the province of Rizal. It involves the construction of 2 water supply infrastructures that will provide Manila Water Company (MWC) 80 million liters (MLD) in its 1st phase to be completed by 2022, and eventually deliver the full 518 MLD in its 2nd phase by the end of 2025.

This project is also expected to address problems of flooding in downstream communities due to typhoons, helping protect the eastern part of Metro Manila and lower areas in the province of Rizal, Marikina, and Pasig.
