Universitas Hasanuddin (Unhas) is deeply committed to protecting water quality and promoting sustainable waste management as an integral part of its environmental responsibility. This commitment is reflected in the adoption of national environmental regulations and the development of internal institutional policies that regulate water quality, hazardous waste, plastic waste, recycling, and resource recovery. Unhas has implemented guidelines, standards, and infrastructure for wastewater management to maintain water quality and protect aquatic ecosystems, wildlife, and human health.  In accordance with Ministerial Regulation No. P.68/Menlhk/Setjen/Kum.1/8/2016, Unhas has strengthened its internal environmental governance through Rector’s Decree No. 10029/UN4.1/KEP/2022  and Circular Letter No. 13826/UN4.1/RT.03.01/2024 on Hazardous and Toxic Waste Disposal.

As a part of direct implementation of wastewater disposal management and control, Unhas has a Wastewater Treatment Plant (WWTP) that has been operating since early 2022. One of the WWTPs built within the Unhas Faculty of Engineering area has a treatment capacity of 300 m³/day with an existing volume of around 104 m³. This system is designed to treat domestic wastewater originating from various campus facilities, including the Sports Hall, Student Center, Science Techno Park, Researcher House, student dormitories, canteen, mosque, and auditorium. The WWTP location was chosen at a relatively low point on campus so that wastewater flow could make use of gravity, allowing the drainage system to operate efficiently. This system is used to treat domestic wastewater generated from campus activities and student facilities before entering the final disposal stage. The existence of the WWTP reinforces the application of wastewater disposal standards at Unhas, as management is carried out not only through regulations but also through centralized treatment before discharge into the environment.

Meanwhile, internal regulations at Unhas prohibit the disposal of B3 waste into water bodies, open land, or public trash bins, and require hazardous waste to be managed using appropriate facilities that comply with applicable requirements and permits. Thus, the potential for pollutants from campus activities to enter aquatic environments can be minimized.

These efforts are also supported by various innovations in water and environmental management. Through HYDROIN (Hasanuddin Rain Water Innovation), Unhas has developed the utilization of rainwater through filtration and treatment processes as part of sustainable water resource management. In Barru Regency, Unhas has implemented coagulation-filtration technology using natural materials to improve the quality of community water, while the biopore infiltration hole program in Sidenreng Rappang Regency integrates organic waste management with enhancing groundwater infiltration.

Through a combination of quality standards, disposal guidelines, internal regulations, WWTP, domestic wastewater treatment, and sustainable water management practices, Unhas demonstrates that water quality protection is applied not only at the policy level but also through infrastructure and operational practices. This approach helps prevent water pollution and reduces the impact of campus activities on aquatic ecosystems, wildlife, and the health and well-being of the community.
