Urban Forest and Wildlife Sanctuary

We share the campus with many interesting species of plants and animals, many of which you may find in the Urban Forest and Wildlife Sanctuary.  To know more about them, join the AEMC Tree and Bird Walks!

Red brick walks

Pedestrian movement and safety is a school priority.  The sidewalk improvement projects have replaced cracked and discontinuous concrete sidewalks with porous paving to improve your pedestrian experience!  Porous paving also allows rainwater to seep through to the soil, decreasing run-off and water wastage.

Marian Garden Integrated Sustainable Irrigation System

Wastewater from the septic tank under the Quad is pumped to a constructed reed bed that treats the wastewater, making it clean enough to reuse for irrigation! A solar panel powers the pumps and UV treatment system and drip irrigation is used to deliver the water directly to the plant roots. This makes the Marian Garden off the grid in terms of electricity and water!

Matteo Ricci Wastewater Treatment System

The Matteo Ricci building is the first zero wastewater building on campus!  Wastewater from the septic tank is pumped through a constructed reed bed for treatment and is delivered via drip irrigation to the nearby garden and lawn.

Decentralized Wastewater Treatment System

The biggest and most recently constructed system is the Decentralized Wastewater Treatment System (DEWATS) near the New Rizal Library. Here, sewage from several buildings is piped into a series of underground aerobic and anaerobic reactors, where sedimentation and the activity of microorganisms help improve water quality.

Grade School Wastewater Treatment

The wastewater treatment facility near Fermin Hall is the Ateneo Grade School’s first!  Built on a slope, it uses gravity transfer wastewater into a series of constructed reed beds.  The treated wastewater is collected and will eventually be used to irrigate the nearby gardens.

New Rizal Library Rainwater Harvesting System

The New Rizal Library has rainwater harvesting capability.  Rain water is collected at the roof and stored in underground cisterns for use in flushing the toilets.  This reduces our water consumption and makes our water use more efficient!  The building is dual piped so we can still flush even during the dry months.

Blue Eagle Pond

The Loyola Schools also has a catchment pond to collect rainwater. This helps in reducing run-off as well as provides irrigation water for the nearby fields and gardens.

Grade School Materials Recovery Facility

The Ateneo Grade School MRF is an important part of the school’s waste management system!  Here, recyclables and reusables are diverted from landfill disposal so that they can be recycled.

High School Materials Recovery Facility

The Ateneo High School MRF is an important part of the school’s waste management system!  Here, recyclables and reusables are diverted from landfill disposal so that they can be recycled.

Loyola Schools Materials Recovery Facility

The Loyola Schools MRF is an important part of our Ecological Solid Waste Management System.  This is where the segregated recyclables, dry paper and reusables are temporarily stored.  The recyclables and dry paper are sold to accredited recyclers and the revenue is given to our maintenance staff bonus fund.  So please use the segregation system wisely!

Loyola Schools Vermicomposting Facility

The LS Vermicomposting Facility accommodates biodegradable wastes such as wet paper, food left overs (minimal at the moment) and yard waste. In the facility, African nightcrawlers digest the waste and convert these into vermicast, a nutritious soil conditioner. This is then used in the lawns and gardens around campus to improve soil quality and reduce the need for chemical fertilizers.

Grade School Vermicomposting Facility

The AGS Vermicomposting Facility is an important part of the school’s solid waste management system.  In this facility, worms digest organic material such as yard waste and left over food into vermicast, which is then used to improve soil quality in the surrounding gardens.  This is also an important demonstration laboratory for science classes.

Department of Environmental Science

The Department of Environmental Science offers several degree programs in environment: Bachelor of Science in Environmental Science, Master of Science in Environmental Science and Master in Environmental Management.  Its faculty is composed of an interdisciplinary group of experts in the biological sciences, ecology, chemistry, geology, natural resource management, and environmental management.   For more information, please visit

Ateneo Institute of Sustainability

The AIS is Ateneo de Manila University’s hub on sustainable development, and the vehicle of the university’s environment-development agenda. Currently there are three programs under the AIS: campus sustainability, inclusive mobility, and climate change and disaster risk. The AIS office is located at the 2nd Floor of the Manila Observatory.

Manila Observatory

The Manila Observatory is a research institution conducting research in air quality and modeling, climate change, and disaster vulnerability mapping.  For more information, please visit
