Busan Metropolitan City Produces Promotional Content for Separated Sewer System Project

내용

Busan Metropolitan City (Mayor Park Heong-joon) announced that it has produced a promotional video to inform citizens about the separated sewer system installation (expansion) project—currently underway to reduce foul odors in the city and create a pleasant living environment—in an easy and engaging way.

This content was planned to help citizens relate to and understand the necessity and benefits of the separated sewer system project, which the City began in 1990 and plans to complete by 2040. It also includes sewerage-related guidelines that citizens can practice in their daily lives, with the aim of improving public understanding of and participation in the project.

Rather than simply delivering information about the project, the promotional video was produced as distinctive, skit-style content to further strengthen communication with citizens.

The video will be released as an episode of the promotional content series Woni’s Self-Sufficient Life—titled “Model Sewer: Separated Sewer System Project”—featuring the responsible City official appearing in person. Using a drama-style format familiar to the public, it is structured as a story in which a “sewer problem-solving team” carries out missions by resolving sewer-related issues across Busan.

By depicting how an odor-related “case” is reported, followed by a prompt on-site inspection and resolution, the video naturally conveys the message: “A safe sewer system begins with citizens’ small but consistent practices.” Busan Metropolitan City plans to continue promoting the importance of sewer management through a variety of media and content.

The promotional video will be available starting in December not only in the “(Civil Servant) Woni’s Self-Sufficient Life” playlist on Busan Metropolitan City’s official YouTube channel (youtube.com/@Busan_is_good), but also on 30 Internet Protocol Television (IPTV) screens installed across Busan.

Meanwhile, Busan Metropolitan City will invest a total of 107.7 billion won in 2026 to install 60.5 kilometers (km) of separated sewer pipes.

The separated sewer system project is designed to reduce odor generation by separating stormwater* and sewage** for treatment. It is highly effective in fundamentally preventing sewer backflow during rainfall, foul odors, and water pollution—problems that used to occur in combined sewer systems. From 1990 to the present, the City has installed 2,741 kilometers (km) of separated sewer pipes (coverage rate: 75.8%).

* Stormwater (雨水): Water that flows when it rains
** Sewage (汚水): Domestic wastewater generated from toilets, kitchens, etc.; contaminated water that requires purification

In 2026, the City plans to invest 107.7 billion won to additionally install 60.5 kilometers (km) of separated sewer pipes across 35 areas.

Lee Byeong-seok, Director General of Busan Metropolitan City’s Environment & Water Policy Office, stated, “We will continue the separated sewer system project, which separates and treats stormwater and sewage, to create a clean and pleasant urban environment free from foul odors,” adding, “We also ask citizens to actively follow sewerage-related guidelines that can be practiced in daily life.”
