Sustainability Metrics
Data is referenced against Ateneo de Manila University School Year (June to May)
Ateneo de Manila University recorded a total water consumption of 357,190 cubic meters for SY 2024–25 (June 2024–May 2025). This volume represents the inbound water supply sourced from Manila Water and treated water, covering the needs of academic facilities, student and staff use, and general campus operations. The Campus Facilities and Management Office (CFMO) is responsible for tracking, monitoring, and managing these systems to ensure efficiency and sustainability.
Volume of Water Used
Water usage peaked in SY 2023–24 at 359,037 m³, reflecting the post-pandemic return to full onsite activities, classrooms, and facility operations. By SY 2024–25, consumption dropped slightly to 357,190 m³, signaling a stabilization of water use while still meeting the same level of campus demand.

Water Potability
Water Potability 2023-2024
In FY 2023–2024, Ateneo de Manila University received seven water-related complaints, mostly on drinking fountain quality and safety. Six were found invalid, while the only valid case in March 2024 at the University Residence Halls was traced to new filters that required longer flushing and was resolved. This reflects the University’s commitment to ensuring safe and reliable drinking water.
Water Potability 2024-2025
Most fountains require filter changes every three months, with fewer on a two-month cycle, and a priority group in cafeterias, dorms, and high-use areas needing monthly maintenance.
