In a statement, Maynilad said the WRF is a key project aimed at expanding wastewater services and contributing to the rehabilitation of Manila Bay. Once operational, the facility will treat up to 88 million liters of wastewater daily, serving about 360,000 residents across 20 barangays in Las Piñas City.
Treated wastewater from the WRF will be safely discharged into the Zapote River, which flows into Manila Bay, helping to reduce pollution and improve water quality.
Strategically located in Barangay Pamplona Uno, the Las Piñas WRF will utilize advanced Anaerobic-Anoxic-Oxic (A2O) technology to remove pollutants effectively. The facility is designed to comply with the Water Quality Guidelines and General Effluent Standards of 2016 (DAO 2016-08) mandated by the Department of Environment and Natural Resources (DENR).
“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 program to accelerate sewerage and sanitation services in Metro Manila. The project is financed through a partnership with the Japan International Cooperation Agency (JICA) and the Development Bank of the Philippines (DBP).
Since 2007, Maynilad has invested over ₱46.4 billion to enhance wastewater infrastructure across 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. —Ed: CSN
