1.Policy Objective

In response to the United Nations Sustainable Development Goal 14.1 — to prevent and significantly reduce marine pollution of all kinds, particularly from land-based activities — National Tsing Hua University (NTHU) is committed to preventing pollutants generated on campus from entering rivers, lakes, and marine ecosystems. The University aims to maintain water quality, protect aquatic ecosystems, and comply with both national and international environmental regulations and best practices.

2.Scope

This policy applies to:

1. The management and discharge of domestic wastewater and laboratory wastewater on campus;

2. Waste and oily residues generated from construction, maintenance, cleaning, catering, and administrative operations;

3. Stormwater management and prevention of non-point source pollution within the campus.

3.Implementation Principles

1. Source Control

All campus units shall implement source control and reduction measures to prevent chemicals, oils, and hazardous materials from entering the drainage system.

2. Wastewater Segregation and Treatment

Domestic wastewater is pretreated before being directed to the municipal sewer system. Laboratory washing water is sent to the university’s treatment plants for compliant discharge. Hazardous laboratory waste liquids are collected and disposed of by licensed contractors under the Waste Disposal Act.

3. Stormwater Separation and Non-Point Pollution Control

The campus drainage network is designed with stormwater-sewage separation, equipped with sedimentation and oil-water separation systems to prevent pollutants from being carried into natural water bodies.

4. Compliance and Continuous Improvement

Discharge quality is monitored in accordance with the Water Pollution Control Act, and continuous improvement is promoted through ISO 14001 and ISO 45001 management systems.

5. Education and Awareness

Environmental education and outreach programs are implemented to raise awareness and responsibility for marine and water resource protection among all faculty, staff, and students.

4.Performance and Transparency

1. Annual summaries of campus wastewater treatment performance shall be published on the university’s sustainability website.

2. Discharge monitoring data shall be reported to the Environmental Protection Administration’s public disclosure platform.

3. Any abnormal or potential pollution incidents shall be promptly reported to the Environmental Health and Safety Center and relevant authorities.

5.Responsible Units

Lead Unit: Environmental Health and Safety Center (EHS Center)

Supporting Units: Office of General Affairs (Construction & Maintenance Division), EHS Center, and all colleges and research institutes.

6.Review and Revision

This policy shall be reviewed and updated every three years, or as required by regulatory changes or operational needs.
