In the Ateneo de Manila University, facilities specifically designed to treat liquid waste minimizes the threat of pollution from excess nutrients or organic matter.
Ateneo de Manila University utilizes two innovative wastewater treatment facilities beside a conventional sewage treatment plant (STP).
One of these, the Decentralized Wastewater Treatment System (DEWATS) possesses the capacity to treat around 110 cubic meters of water every day, specifically waste from seven major university buildings.
Additionally, the Building Wastewater Treatment Systems (BWATS) established the Matteo Ricci Study Hall as the first zero wastewater building on campus. The system has been put in place as well in some of the university’s older buildings and installed in recently built-in facilities such as the International Residence Hall.
The Campus Wastewater Discharge Plan of the Central Facilities Management Office (CFMO) establishes the location of the above systems and the buildings to which they are connected. The plan also includes the additional wastewater treatment systems that would complete the proposed eight (8) systems that would cover the broad area of the university.
