Waste Water Discharge

As per the Republic of the Philippines Act no. 9275, the University must follow the regulations and guidelines regarding water discharge. The Congress of the Philippines ratified this act to implement a comprehensive water quality management system and for other relevant purposes.

Maynilad, the University's water provider, granted the Intramuros campus a Certificate of Interconnection. Our wastewater is conveyed to the Tondo Sewage Pumping Plant for preliminary treatment through our sewer service connection with Maynilad before it is pumped to a 5.9 km ocean outfall with diffusers. The facility operates under a discharge permit issued by the Laguna Lake Development Authority.

The mandatory connection of buildings to a sewerage system is required by Section 305.1 of the Revised Plumbing Code of the Philippines, Section 74(a) of the Sanitation Code of the Philippines, and Section 8 of the Clean Water Act, and the University complies with these regulations.

The Intramuros campus was also issued a Certificate of Discharge Permit Exemption in accordance with Section 4(d) of Republic Act 4850. This exemption authorizes Mapua University to discharge regulated liquid waste or wastewater effluent without securing a Discharge Permit. The wastewater generated by Mapua is permitted to be tapped and is verified to be interconnected to the Centralized Wastewater Treatment Plant or Facility of Maynilad Water Services, Inc. – Tondo Sewage Pumping Plant.

For the newly constructed Makati campus, we have a wastewater treatment system with a separate piping system that flows to the Sequencing Batch Reactor (SBR) sewage treatment plant with a capacity of 150 cubic meters per day. The SBR is an effective wastewater treatment system used in sewage treatment plants to remove contaminants and produce high-quality effluent. Manila Water Inc. provides our main water supply. We also have a facility for reusing non-potable water from treated water from STP for flushing water closets and urinals. The building is designed with a 2-pipe system for potable and non-potable water, and all faucets, shower heads, and bidets are connected to potable water.
