The Aglipay Sewage Treatment Plant in Mandaluyong will be Manila Water’s largest and most advanced facility, treating up to 120 million litres of wastewater per day
Part of the Mandaluyong West, San Juan South and Quezon City South Sewerage Scheme, the new plant will serve 652,000 residents across a 20 km2 catchment. To deliver the project, Manila Water has been supported by Binnies Philippines in consortium with DCCD Engineering Corporation for master planning, feasibility study, reference and detailed design and construction management services.
YS Tse continues: “The infrastructure installed on the compact site has the capacity to service a growing population up to an ultimate capacity of some 700,000 residents and is set to start operation in early 2026.
“The conveyance system of the sewerage scheme when fully completed includes 53 km of sewers and a 100-million-litre-per-day pumping station at a depth of 20 metres below ground. After wastewater has been collected through this system, it will then be treated at the new centralised treatment plant that has biological nutrient removal capability.”
Tse explained that the Aglipay plant has been designed to meet the stringent 2016 version of the Philippine Water Quality Guidelines and General Effluent Standards: “The 2016 standards require nitrogen and phosphorus to be removed to very low levels. To achieve this, Binnies specified the use of moving bed biofilm reactor (MBBR) technology, harnessing microorganisms to remove the nutrients in the sewage, thereby reducing the use of chemicals. Effective biological nutrient removal with low energy and chemical consumption is the key objective of the project.
“The sewerage system is being progressively implemented and therefore has been designed initially as a combined system, collecting sewage and rainwater. Over the course of the implementation period, it is expected to become more ‘separate’, collecting stronger sewage by excluding more rainwater. The MBBR system was chosen for its robustness to cater for the changing sewage property during this process. There is also provision for including sludge treatment when more biosolids are expected in the future.”
