Emphasizing that a proper wastewater system is complemented by responsible water disposal, President Marcos has encouraged stakeholders and the public to contribute in the protection of waterways in the country.

"Clean facilities must be matched by clean habits. Proper wastewater systems must be complemented by responsible waste disposal," Marcos said.

"So, I call on everyone—the government, private sector, and the citizens alike: Let us all do our part. Protect our waterways. Keep our surroundings clean and healthy," he added.

Marcos made the call during the inauguration of the 60-million-liters-per-day (MLD) Aglipay Sewage Treatment Plant (STP) in  Barangay Old Zañiga, Mandaluyong City on Friday, Jan. 16.

In his speech, the President stressed that "true progress also demands collective discipline and shared accountability," thus, he made the call.

He also vowed that his administration will continue to strengthen the water and sanitation infrastructure across Metro Manila and beyond.

Marcos cited the goal of connecting 76 percent of households in Metro Manila, Cavite, and Rizal to sewerage systems by 2047. The remaining 24 percent will be covered by proper sanitation services.

"This means that no community is left without safe and responsible wastewater management," he said.

The Chief Executive also recognized the role of Manila Water and Megawide Consortium in delivering this critical infrastructure.

"Your expertise and capacity are essential to ensuring that these facilities meet environmental standards and deliver reliable service to the public," Marcos said.

"This forms a part of our larger vision: a Philippines where economic progress goes hand in hand with environmental stewardship, strong public health systems, and people-centered service delivery," he added.

In leading the inauguration of the sewage plant in Mandaluyong, Marcos said its impact will be felt every single day, with the capacity to treat 60 million liters of wastewater every day, expandable to 120 million liters per day.

"This means that more liters of safe water is available for public consumption and more rivers and seas are preserved for future generations," he said.

The President also underscored that the project supports the long-term rehabilitation of the Manila Bay.

"By reducing pollution flowing into rivers within its service area, this facility will improve local water quality. It also supports the long-term rehabilitation of Manila Bay by limiting the pollution load that eventually reaches our seas," Marcos said.

"These are not abstract aspirations, but concrete and measurable actions towards protecting our [environment] and restoring our natural resources," Marcos added.

According to the President, the plant serves 2,115-hectare catchment area across Mandaluyong, San Juan, and Quezon City, benefitting over 650,000 residents.

It is under the management of Manila Water and was built at a cost of P3.93 billion.
