President Ferdinand “Bongbong” Marcos Jr. on Saturday led the inauguration of the ₱3.93-billion Aglipay Sewage Treatment Plant (STP) in Mandaluyong City, a facility designed to treat 60 million liters of wastewater daily.
Covering a catchment area of 2,115 hectares across Mandaluyong, San Juan, and Quezon City, the plant—managed by Manila Water—will benefit more than 650,000 residents.
Wastewater collected through a 53-kilometer sewer-drainage system will undergo full treatment before being discharged into the Pasig River.
“Beyond the machinery, fascinating as it is, 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,” Marcos said.
He added, “This is how a carefully planned and thoroughly executed infrastructure directly improves the lives of our people. This means that more liters of safe water are available for public consumption and more rivers and seas are preserved for future generations.”
The President noted the facility can be expanded to 120 million liters per day to meet future demand. Awarded in 2019 to the Megawide Consortium, the project is part of Manila Water and MWSS’s broader initiative to expand sewerage systems in the east zone.
Marcos emphasized that reducing untreated wastewater will improve water quality and aid in rehabilitating Manila Bay. He also highlighted ongoing construction of five more wastewater treatment plants in Metro Manila and nearby provinces.
Under the Revised Concession Agreement and Republic Act Nos. 11600 and 11601, the government targets connecting 76% of households in Metro Manila, Cavite, and Rizal to sewerage systems by 2047, with the remainder covered by proper sanitation services.
