The rapid expansion of population and economic activities has resulted in the generation of substantial volumes of wastewater, posing significant environmental challenges. Despite the availability of a diverse array of wastewater treatment (WWT) technologies, the selection of the most appropriate solution remains complex due to the multitude of criteria that must be simultaneously considered. This study proposes a decision-making framework based on the Analytic Hierarchy Process (AHP), employing pairwise comparisons to facilitate the sustainable selection of WWT technologies. The AHP methodology is utilized to derive the relative weights of decision criteria, with the consistency ratio serving as a measure to validate the coherence of expert judgments represented through pairwise comparison matrices. Computational results reveal that 'Composting,' with a composite weight of 0.4370, is identified as the most preferred WWT option. Future research should further investigate critical decision-making factors, including technological variability, the credibility of decision-makers, and the methodological robustness of AHP within broader conceptual frameworks.
