Manila Water builds water treatment plant at Laguna Lake to serve more Rizal towns

In order to provide quality water service to the underserved areas in the east Zone, Manila Water is participating in the building of the East Bay water treatment plant (WTP) that will draw water from the eastern part of Laguna Lake, considered the cleanest portion of the lake. The East Bay WTP is part of the East Bay Water Supply System Project that seeks to expand Manila Water’s services to more towns in Rizal Province.

“Components of the Php 2.7B WTP project include an eight-million-litre capacity reservoir, an intake structure, pumping station, and Water Treatment plant using dissolved air flotation (DAF) system, multi-media and granular activated carbon (GAC) filters as well as reverse osmosis system,” shared Byder Nangit, senior project manager of Manila Water.

Manila Water’s project management group (PMG) acknowledged that a project as massive as this requires the cooperation and buy-in of key stakeholders to be completed and operational as scheduled.

“Manila Water has been regularly coordinating with the relevant Local Government Units and the Laguna Lake Development Authority (LLDA) to ensure that the project complies with all necessary laws and regulations and is implemented upholding strict safety protocols,” added Badet Del Rosario, stakeholder engagement department head of Manila Water PMG.

Construction is expected to be completed by April 2023, which will be followed by testing and process proving. Once operational, the phase one East Bay WTP is designed to provide 50 million litres of treated water per day to 390,000 individuals from the towns of Jala-Jala, Pililla, Baras, Cardona, Morong, and Binangonan in Rizal Province.

To complement the WTP, two submarine pipelaying projects are also currently being implemented. One pipe system connecting Morong to Cardona is 50% complete, while another HDPE pipe system connecting Pililla to Morong has already begun construction. These submarine transmission lines will convey treated water from the WTP to the distribution system to safely reach customers once the facilities begin operations.
