Wastewater Management System

Nakhon Si Thammarat Rajabhat University (NSTRU) has implemented a systematic wastewater management plan to ensure that all wastewater generated on campus is properly treated before being discharged into the environment.

Every building on campus is equipped with an underground septic tank to collect and pre-treat wastewater before it is released into the university’s drainage canal. This canal is designed to facilitate a natural aeration process, which increases oxygen levels, reduces organic matter, and improves water quality before the water exits the university area.

Quality Monitoring and Improvement

The university regularly monitors and assesses wastewater quality to ensure compliance with environmental standards. These assessments help maintain high water quality and reduce the environmental impact of wastewater discharge.

Currently, the university is constructing a new aeration-based wastewater treatment system designed to enhance the efficiency of organic pollutant removal. This upgraded system will collect wastewater from multiple buildings and integrate with existing septic tanks and aeration canals, creating a more comprehensive and sustainable treatment process.

Reuse and Sustainability Initiatives

To promote sustainable water use, the university is collecting data on the volume of wastewater generated and plans to reuse treated water for activities such as:

• Plant watering and landscape maintenance
• Cooling systems and non-potable use
