Through key infrastructure investments like the 50-MLD East Bay Phase 1 Water Treatment Plant, Manila Water continues to provide reliable 24/7 water service to more than 7.9 million customers while strengthening water supply resilience and reducing reliance on Angat Dam.
MANILA, Philippines – Amid concerns over the effects of El Niño and lower water allocations from Angat Dam, Manila Water assures customers across its East Zone concession area of continued 24/7 water supply, backed by years of strategic investments in alternative water sources, including the East Bay Phase 1 Water Treatment Plant (WTP).
Physically completed in 2024 and started commissioning and process proving in 2025, the East Bay Phase 1 WTP has become a critical component of Manila Water’s strategic water reserves, providing up to 50 million liters per day (MLD) of treated water drawing water from the eastern flank of Laguna Lake. The P2.7-billion facility features an 8-million-liter reservoir, intake and pumping facilities, and a multi-stage treatment process that utilizes Dissolved Air Flotation (DAF), granular activated carbon filtration, and reverse osmosis technologies to ensure water quality. By tapping an alternative raw water source outside of Angat, the facility strengthens supply reliability and resilience and enhances the company’s ability to meet customer demand during periods of reduced water availability and climate-related challenges.
