Wastewater Management Policy
Prince of Songkla University (PSU) has established a wastewater management policy in accordance with the National Environmental Quality Promotion Act. The objective is to manage wastewater efficiently and hygienically, ensuring that wastewater treatment within the university complies with the Ministry of Natural Resources’ announcement on wastewater discharge standards from certain types and sizes of buildings, dated December 29, 2005.
The university’s wastewater management policy is hereby announced as follows:
1.Repair and Maintenance: The wastewater treatment systems in damaged buildings such as classrooms, offices, and residences within the university must be repaired to ensure normal functioning.
2.New Building Requirements: All new buildings that request budget or undergo renovation must include a preliminary wastewater treatment system before discharging into the university’s sewer system. The discharged water must meet the prescribed quality standards.
3.Monitoring and Control: There must be continuous monitoring and control of wastewater from all departments, including treated wastewater.
4.Reuse of Treated Water: The university supports the reuse of treated wastewater for purposes such as watering plants within the university.
5.Research and Innovation: The university encourages and promotes research and innovation in wastewater management.
The university has a wastewater treatment system using an aerated lagoon system. After that, all wastewater is collected in a stabilization pond for further treatment to improve water quality. The water quality is monitored to ensure that the Biochemical Oxygen Demand (BOD) does not exceed 18 milligrams per liter before being discharged. Additionally, the university has published an operational manual for monitoring and controlling the wastewater treatment system at Prince of Songkla University, Hat Yai Campus, authored by Mr. Phana Mektrong. This manual is available on the website of the Division of Physical and Environmental Affairs. Operational manual for monitoring and controlling the wastewater treatment system
