West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) is making significant progress on its second NEW WATER facility, now under construction in Pasay City. This pioneering initiative converts used water into potable water, offering a sustainable solution to augment Metro Manila’s water supply.
As of March 2025, the Pasay NEW WATER Treatment Plant is 82% complete. The facility will utilize a multi-stage treatment process that purifies used water to meet the Philippine National Standards for Drinking Water (PNSDW) set by the Department of Health (DOH). It is expected to benefit underserved communities in Pasay by boosting water availability.
Targeted for completion by December 2025, the Php700-million facility is designed to produce 12 million liters per day (MLD) of NEW WATER—enough to serve around 60,000 residents.
Maynilad already operates a similar facility in Parañaque City, which marked the company’s first foray into potable water reuse. Commissioned in 2022 under a conditional permit from the DOH, the Parañaque NEW WATER Treatment Plant received its permanent operational permit in 2023. It currently supplies 5 MLD of safe drinking water to two barangays and was internationally recognized as “Water Reuse Project of the Year” at the 2023 Global Water Awards, highlighting its role in advancing water reuse technologies.
Aside from the ongoing Pasay development, Maynilad is also expanding its NEW WATER program with other upcoming facilities in other areas, as well as an upgrade of the existing Parañaque plant. By 2027, these initiatives are projected to deliver a combined output of up to 90 MLD, providing a reliable, climate-resilient alternative water source for Metro Manila.
“Maynilad’s NEW WATER initiative is a key part of our sustainability strategy,” said Maynilad President and CEO Ramoncito S. Fernandez. “It not only provides additional water supply but does so in a way that eases pressure on our traditional sources amid growing demand and the effects of climate change.”
Maynilad is the largest private water concessionaire in the Philippines in terms of customer base. It is a concessionaire of the Metropolitan Waterworks and Sewerage System (MWSS) 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.
