National Cheng Kung University (NCKU) has established wastewater management guidelines for its campus buildings and research facilities to efficiently manage the discharge of wastewater and ensure that its water quality complies with discharge and regulatory standards. These guidelines are formulated in accordance with the Water Pollution Control Act, Waste Disposal Act, Tainan City Sewerage Management Ordinance, and other relevant environmental laws and regulations. The university aims to reduce water quality pollution and create a healthy and safe campus and community.

Furthermore, NCKU carefully monitors every step of liquid waste classification, storage, transport, and data recording to prevent experimental contamination and environmental hazards, thus fulfilling its social responsibility as a responsible academic institution.

In terms of on-campus environmental monitoring, NCKU's Environmental Health and Safety Center conducts various campus environmental monitoring projects, including monitoring the water quality of external drainage, campus building drainage, and groundwater. Multiple sampling spots are utilized, and tests for parameters such as total dissolved solids, suspended solids, BOD, COD, and ammonia nitrogen are performed to provide on-site sampling data, ensuring the quality of wastewater discharge.
