This study aims to identify and prioritize key criteria for the site selection of construction wastewater treatment (WWTP) in Ho Chi Minh City. A comprehensive literature review was conducted to establish a preliminary list of 27 criteria, which were then evaluated through expert surveys using a five-point Likert scale. The Relative Importance Index was applied to quantify the significance of each criterion. The results identified seven criteria as highly important: proximity to water bodies, proximity to human settlements, land use/land cover, proximity to protected areas, proximity to roads, slope, and soil type. These findings provide a basic review of sustainable criteria in selecting WWTP sites that align with the Sustainable Development Goals of HCMC. While the study is limited by a small expert sample and the absence of spatial analysis, it contributes valuable insights for urban infrastructure planning in similar developing contexts.
