Pasay, Philippines – Pasay NEW WATER Treatment Plant

Maynilad, which now serves around 10 million customers in the West Zone of Metro Manila, is expanding its trailblazing potable water reuse initiative with the development of the Pasay NEW WATER facility – its second direct potable reuse installation in the Philippines.

This initiative is part of Maynilad’s long-term strategy to diversify water sources and strengthen supply resilience in the face of growing demand and the increasing vulnerability of existing sources like Angat Dam. As climate change continues to intensify weather extremes such as droughts and typhoons, direct potable reuse offers a sustainable, climate-adaptive solution for enhancing water security.

The Pasay NEW WATER facility will draw its raw water from the treated effluent of Maynilad’s Pasay Water Reclamation Facility. Rather than discharging this effluent – already compliant with standards of the Department of Environment and Natural Resources – into nearby receiving bodies of water, it will undergo further treatment through advanced purification processes to meet the 2017 Philippine National Standards for Drinking Water.

Set for completion by the fourth quarter of 2025, the facility will produce 12 million liters per day, directly benefiting around 78,500 people in the Malibay area of Pasay City. Once operational, the combined output of Maynilad’s Parañaque and Pasay NEW WATER facilities will account for approximately 0.7% of the company’s overall water supply.

While the Pasay site does not yet feature a visitor center, Maynilad welcomes tours by request to promote public awareness and support for water reuse innovations.
