The first phase of the PWTP 1 upgrade will cover part of the plant’s existing ultrafiltration system and is targeted for progressive commissioning starting by the end of 2026.
It forms part of Maynilad’s broader program to enhance the reliability of its Laguna Lake treatment facilities, which serve as alternative sources to Angat Dam and help support water security for customers in the West Zone.
Once the phase is completed, the upgrade is expected to support more stable and reliable treatment operations, particularly during periods of elevated turbidity in Laguna Lake.
Maynilad is pursuing investments in advanced treatment technologies as part of its continuing efforts to improve supply reliability, diversify raw water sources and strengthen climate resilience across its water production system.
Maynilad operates the largest water concession by population served within a single concession area in the Philippines. It is a concessionaire of the Metropolitan Waterworks and Sewerage System for the West Zone of the Greater Manila Area, which is composed of the cities of Manila (certain portions), Quezon City (certain portions), Makati (west of South Super Highway), Caloocan, Pasay, Parañaque, Las Piñas, Muntinlupa, Valenzuela, Navotas and Malabon all in Metro Manila; the cities of Cavite, Bacoor and Imus, and the municipalities of Kawit, Noveleta and Rosario, all in Cavite Province.
