Odor problems from sewer pipelines significantly affect urban environments and public health, directly influencing both urban competitiveness and residents’ quality of life. This study systematically examines the current status and challenges of sewer odor management, while proposing practical and effective improvement measures informed by domestic and international best practices. Particular attention is given to the primary causes of odor generation, including sediment accumulation, biofilm formation, and critical odor-prone sites. Based on these findings, the study recommends the establishment of scientific monitoring systems, the adoption of site-specific technologies, and the implementation of integrated management strategies for odor mitigation. In addition, it identifies limitations in the existing management framework and regulatory system, offering policy and institutional directions for improvement. By combining technological and institutional approaches, this research provides a comprehensive strategy to reduce sewer odor problems and contributes to building more sustainable and livable urban environments.
