Manila Water is set to build a new 200 million liters per day (MLD) water treatment plant (WTP) which will provide additional supply of potable water to Metro Manila’s East Zone after inking a partnership deal with ACCIONA, PrimeBMD, and Santa Clara International, which form the consortium which will design and construct the facility. 

The Php 7.84 billion East Bay Phase 2 WTP, located in Brgy. Kabulusan, Pakil, Laguna, is expected to deliver potable water to an estimated population of 2 million in Pasig, Pateros, Taguig, and nearby towns by the first few months of 2025.  Manila Water Senior Project Manager Engr. Byder Nangit said that this project is part of the company’s Water Supply Master Plan that aims to ensure water security and supply reliability in the East Zone. Once completed, the project will also lessen water supply dependence on Angat Dam.

The WTP is part of the East Bay Phase 2 Water Supply System (WSS) Project, which also includes the construction of a reservoir, pumping station, and pipelaying of 60 kilometers of 1200- and 1400-millimeter diameter pipes. The WTP will treat the water from the Laguna Lake using reverse osmosis process, making it suitable for public consumption.

By the second quarter of this year, the Phase 1 of the East Bay WSS Project was substantially completed and is now serving customers of the Municipality of Jalajala. The facility is expected to provide 50 MLD of treated water to 390,000 population in the towns of Jalajala, Pililla, Baras, Cardona, Morong, and Binangonan in Rizal Province, complemented by two submarine pipes traversing the bottom of Laguna Lake.
