President Ferdinand Marcos Jr. inaugurated a P3.93-billion sewage treatment plant Friday, a facility designed to improve water quality for more than 650,000 residents in Metro Manila.

The Aglipay Sewage Treatment Plant has the capacity to process 60 million liters of wastewater per day. Managed by Manila Water, the facility serves a 2,115-hectare catchment area covering parts of Mandaluyong, San Juan and Quezon City.

During the unveiling, Marcos said the project is a concrete step toward ensuring all Filipinos have access to clean water and a healthier environment. He noted that the facility’s capacity could eventually expand to 120 million liters per day to accommodate urban growth.

“Beyond the machinery, what really matters is the result, and that is cleaner water returned to the environment and reduced exposure of our people to the hazards of untreated sewage,” the President said.

By filtering wastewater before it reaches local rivers, the plant is expected to support the long-term rehabilitation of Manila Bay. Marcos said five additional treatment plants are currently under construction as part of a broader administration program to modernize sanitation infrastructure in the capital and surrounding provinces.

The government aims to connect 76 percent of households in Metro Manila, Cavite and Rizal to formal sewerage systems by 2047, with the remainder covered by other sanitation services.

Marcos also credited the Manila Water and Megawide Consortium for the construction of the facility, praising the partnership’s ability to meet environmental standards and provide reliable utility services.
