KMUTNB has implemented a systematic wastewater treatment process to ensure that all wastewater generated on campus is properly treated before discharge. The university employs an aeration treatment system, which enhances the biological degradation of organic matter, ensuring compliance with environmental standards and minimizing ecological impact.

Each faculty and operational unit manages its wastewater responsibly. For example, the Faculty of Industrial Technology and Education (ITED) operates an on-site aeration wastewater treatment pond. Faculty engineers routinely inspect and monitor the system’s performance to maintain treatment efficiency. Monthly maintenance includes checking air pumps, while a comprehensive cleaning cycle is conducted every five years to remove sludge and reintroduce beneficial microorganisms.

Additionally, KMUTNB has installed grease traps and promotes proper wastewater pre-treatment in cafeterias and laboratories to prevent contamination and improve treatment quality.
