Domestic Wastewater Sewerage Treatment Facilities – Domestic wastewater discharge is the highest contributor to Manila Bay’s organic pollution. Only 18 percent of the wastewater generated in Metro Manila households was collected by localized separate sewerage systems. Nearly all of this was discharged through an outfall into Manila Bay. Most residential wastewater (82 percent) was discharged into the public drainage system either directly or through one million septic tanks. These septic tanks were not desludged and the effluent poured into the waterbodies was essentially untreated, causing heavy pollution everywhere in Metro Manila, particularly in high density areas.
Through its Manila Second Sewerage Project (MSSP), Metropolitan Waterworks and Sewerage System (MWSS) aims to expand its septage management program to provide low-cost improvement of sewerage services. Further, it will reduce pollution in waterways and in Manila Bay, thus reducing the health hazards. The project includes construction of a pilot septage treatment plant; rehabilitation of the Central and the Ayala Sewerage Systems, the Ayala and the Dagat-Dagatan sewage treatment plants, and individual sewer connections; and provision of on-site treatment community sanitation.
