West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) has reported progress on its P4.84-billion Water Reclamation Facility (WRF) in Las Piñas City, a project aimed at improving wastewater management and contributing to the rehabilitation of Manila Bay.

A milestone for wastewater services

The Las Piñas WRF, currently 33% complete, is expected to be operational by July 2026. Designed to process up to 88 million liters of wastewater daily, the facility will serve approximately 360,000 residents across 20 barangays in Las Piñas City. Treated wastewater will be safely discharged into the Zapote River, reducing pollution levels and enhancing water quality in Manila Bay.

Located in Barangay Pamplona Uno, the facility will employ Anaerobic-Anoxic-Oxic (A2O) technology, ensuring effective pollutant removal. It is designed to comply with the Department of Environment and Natural Resources' (DENR) Water Quality Guidelines and General Effluent Standards of 2016 (DAO 2016-08).

Focus on environmental sustainability

“Our construction timeline was unfortunately delayed by pandemic restrictions in 2020, but we resumed work in 2023 with renewed focus. This project reinforces our commitment to providing reliable wastewater services for our customers and easing the pollution burden on Manila Bay,” said Maynilad President and CEO Ramoncito S. Fernandez.

The Las Piñas WRF is part of Maynilad’s broader efforts to accelerate sewerage and sanitation services in Metro Manila. The project is financed in partnership with the Japan International Cooperation Agency (JICA) and the Development Bank of the Philippines (DBP), reflecting a commitment to sustainable infrastructure development.

Since 2007, Maynilad has invested over P46.4 billion to enhance wastewater infrastructure within its concession area. The company currently operates 22 Sewage Treatment Plants, two Sewage and Septage Treatment Plants, and one Septage Treatment Plant, with a combined treatment capacity of approximately 724,000 cubic meters per day.
