In this study, the performance of the wastewater treatment plant, which treats approximately 80,000 m³/day of domestic and industrial wastewater in the Bursa, Turkey, for the 2018–2020 period, is evaluated based on the analysis of chemical oxygen demand (COD), biochemical oxygen demand (BOD), suspended solid (SS), total nitrogen (TN), total phosphorus (TP), color, and some heavy metals (Cr⁺⁶, CN⁻, Cd, Fe, Cu, and Zn) parameters. Treatment plant removal efficiencies were 61–91% for COD; 78–97% for BOD; 54–94% for SS; and 57–84% for TN. It was detected in the range of 23–84% for TP and 40–68% for color. The operating costs per treated wastewater volume were calculated as 0.0675 USD/m³ and 2.94 USD/kg COD per organic load removed. The quality of treated water was compared with the discharge limits of the receiving medium, and no limit values were exceeded in any parameters during the monitoring years.
