Wastewater treatment plants (WWTPs) are critical infrastructure that play a decisive role in protecting water resources, preventing groundwater pollution, and improving public health, with this study focusing on the East Ahvaz WWTP (112,000 m³/day capacity) and employing a novel EFMEA-TOPSIS hybrid approach to assess environmental and health risks by first quantifying three key parameters—Severity (S), Occurrence (O), and Pollution Extent (E)—for 18 operational risks through field surveys and expert input from 10 specialists to calculate Risk Priority Numbers (RPN), then transforming these into TOPSIS-weighted criteria (equal 0.333 weights) for empirical ideal-solution-based ranking, where results identified two high-priority risks—biological process disruption (RPN=175, caused by nutrient supply/aeration deficiencies) and toxic sludge contamination (RPN=144, from industrial effluents/groundwater leakage)—as unacceptable (H-level), while TOPSIS confirmed high energy consumption (RPN=80) ranked third due to systemic impacts, prompting proposed solutions like online effluent monitoring, smart nutrient ratio control, and dedicated sludge treatment for heavy metal removal and safe hazardous waste disposal.
