Ayala Alabang Village Sewage Treatment Plant - Philippines Wastewater Facility

Ayala Alabang Village Sewage Treatment Plant is an operational wastewater facility located in the Philippines, serving the Ayala Alabang Village residential community. The plant is situated in the southern part of Metro Manila, an area with significant urban development. As a municipal wastewater treatment plant in the Philippines, it operates under the country's Clean Water Act (Republic Act 9275), which mandates proper sewage treatment for communities. Facilities of this scale typically employ biological treatment methods to meet national effluent standards. The plant discharges treated wastewater into the local drainage system, which ultimately flows into Laguna de Bay, the largest lake in the Philippines. This water body supports diverse aquatic life and is a critical resource for fisheries, agriculture, and domestic use in the surrounding region.

The plant's treated effluent enters the local drainage network that feeds into the Pasig River system, which flows into Laguna de Bay. This lake is a major freshwater ecosystem supporting fisheries and biodiversity. The surrounding watershed is densely populated and faces pressures from urbanization and industrial activities, making proper wastewater treatment essential for protecting water quality and aquatic habitats.
