MANILA, Philippines — President Marcos led yesterday the inauguration of a P3.93-billion mega sewage treatment plant in Mandaluyong City that has an initial capacity to treat 60 million liters of wastewater daily. The Aglipay Sewage Treatment Plant (STP) will treat domestic wastewater from a catchment area of approximately 2,115 hectares, covering portions of Mandaluyong, San Juan and Quezon City. Wastewater collected through a 53-kilometer combined sewer-drainage system will undergo full treatment before being discharged into the Pasig River. As part of his administration’s push to strengthen water and sanitation infrastructure in Metro Manila and nearby areas, Marcos said five more wastewater treatment plants are currently under construction.
