Las Piñas wastewater facility facing delays, completion now expected by mid-2026

Published Jan 13, 2025 05:43 am

Despite construction delays, West Zone concessionaire Maynilad Water Services, Inc. announced that its Las Piñas Water Reclamation Facility (WRF) is now progressing steadily and is expected to be completed by mid-2026.

In a statement on Monday, Jan. 13, Maynilad reported that the P4.84 billion facility, which will expand wastewater services and contribute to the rehabilitation of Manila Bay, is approximately 33 percent complete.

The Las Piñas WRF, now slated to begin operations by July 2026, will have the capacity to treat up to 88 million liters of wastewater per day, serving approximately 360,000 residents in 20 barangays.

Maynilad said the treated wastewater will be safely discharged into the Zapote River, which flows into Manila Bay, minimizing pollution and improve water quality.

The facility also adheres to the water quality guidelines and standards set by the Department of Environment and Natural Resources (DENR), Maynilad said.

Ramoncito S. Fernandez, Maynilad president and chief executive officer, explained that construction resumed in 2023 following the easing of pandemic restrictions.

“Our construction timeline was unfortunately delayed by pandemic restrictions in 2020, but we resumed work in 2023 with renewed focus," Fernandez said.

"This project reinforces our commitment to providing reliable wastewater services for our customers and easing the pollution burden on Manila Bay,” he added.

Financed by the Japan International Cooperation Agency (JICA) and the Development Bank of the Philippines (DBP), the WRF is part of Maynilad's larger program to expand sewerage and sanitation services.

Located in Barangay Pamplona Uno, the facility will utilize advanced Anaerobic-Anoxic-Oxic (A2O) technology to remove pollutants from the water.

Since its reprivatization in 2007, Maynilad has invested over P46.4 billion in wastewater infrastructure across Metro Manila and its other service areas.

Currently, it 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.

“This latest facility is a testament to Maynilad’s continued dedication to environmental sustainability and public health through improved wastewater management,” Maynilad said.
