Busan's Sewer Administration Ranks First Among Metropolitan Governments Nationwide... Achievements in Flood Prevention and Aging Pipeline Management

Received 'B' Grade in This Year's Local Public Enterprise Management Evaluation

Busan's sewer management has received the highest evaluation among all metropolitan governments nationwide.

The City of Busan raised both its rating and overall ranking compared to the previous assessment by prioritizing projects directly connected to citizen safety, such as managing flood-prone areas, preventing manhole accidents, and renovating aging sewage pipelines.

Busan City (Mayor Jeon Jae-soo) announced on August 10, 2026, that it ranked first among nine metropolitan governments nationwide and received a 'B' grade in the metropolitan sewerage sector of the "2026 Local Public Enterprise Management Evaluation" supervised by the Ministry of the Interior and Safety.

In the sewerage management evaluation conducted biennially by the Local Public Enterprise Evaluation Institute, Busan advanced from the previous "C" grade in 2024 to the next level. The ranking, which was second among all metropolitan governments nationwide at that time, has now risen to first place.

In this evaluation, the city's accomplishments in establishing and maintaining sewerage infrastructure for flood prevention and citizen safety were highly regarded.

Busan intensively managed designated control zones with high flood risk and proactively installed manhole fall prevention devices. The city also completed a thorough investigation of aging sewage pipelines, thereby creating a foundation for managing pipeline conditions using data.

Expansion and improvement of sewerage facilities were also assessed. While stably carrying out the separate sewer system project, Busan has also begun in earnest the construction of the deep tunnel rainwater storage along Oncheoncheon and the modernization of sewage treatment plants.

The sewerage management evaluation assesses nine metropolitan governments nationwide based on two areas—management and performance—and a total of 18 detailed indicators. This year's evaluation was conducted through document reviews and online assessments.

Shim Jaemin, Policy Chief of Busan City's Environmental Water Policy Office, said, "Achieving first place is the result of all employees working together for the safety and improved quality of life for our citizens. We will continue to strive to provide a sewerage service that citizens can trust through ongoing management improvements and the continuous establishment of sustainable sewerage infrastructure."
