Universitas Diponegoro (UNDIP) upholds strict water discharge guidelines aligned with Peraturan Daerah Kota Semarang No. 2 Tahun 2023 tentang Pengelolaan Air Limbah Domestik, ensuring wastewater is treated before release to protect ecosystems, wildlife, and human health. All discharges from laboratories, dormitories, and campus facilities must meet Baku Mutu Air Limbah Domestik standards, covering parameters such as pH, BOD, COD, TSS, and coliform. Treatment is carried out through physical, biological, or chemical processes using SPALD systems (Setempat and Terpusat) to prevent contamination of surface and groundwater. Effluent quality is monitored at least every six months and reported to the local environmental agency. Treated water is reused for non-potable purposes (toilet flushing, irrigation, fire hydrants), and sludge is composted for non-food plants, supporting UNDIP’s circular campus program and sustainable water management in compliance with national and municipal environmental regulations.
