Clear Valley Water Flows in an Urban Stream
The city of Busan has completed the installation of a rainwater and sewage separation wall in the covered area of the Bujeon Stream. As a result, clean valley water flowing from the Seongjigok Water Source will directly flow into the Dongcheon.
This measure is expected to contribute to the improvement of water quality in urban streams and enhance the efficiency of sewage treatment.
Additionally, in the area around Dongcheon in Jeonpo-dong, the 'Gwangmu Waterfront Park Development Project' is actively underway, which is anticipated to further improve the local environment.
7,000 Tons of Clear Water Flowing into Dongcheon Daily
Through this project, clean valley water flowing from Seongjigok will average 7,000 tons per day, amounting to about 2.55 million tons annually, flowing directly into Dongcheon. Previously, valley water mixed with household sewage flowed into sewage treatment facilities, but with the installation of the separation wall, a system has been established to effectively separate clear water from sewage.
As a result of this achievement, Busan is expected to enhance the self-purification function of Dongcheon, and the valley water from Seongjigok used as maintenance water for urban streams is anticipated to significantly contribute to improving water quality.
Overview of the Construction and Progress
The ongoing project is the installation of a rainwater and sewage separation wall over a 1.7km section from the Citizen Park in Busanjin-gu to Gwangmu Bridge. This project includes a total of 3.5km of separation wall, divided into 1.8km on the left bank and 1.7km on the right bank.
Moreover, this construction also includes measures to remove four sedimentation tanks and two weirs to improve the flow of water in the stream. The construction started in 2023 and is scheduled to be completed in September 2025.
This project commenced in October last year and is expected to be completed by September 15. After completion, it is anticipated to resolve structural issues in the covered Bujeon Stream and significantly alleviate the odor problems caused by pollutants and sediments.
Improvement of Water Quality and Enhancement of Sewage Treatment Efficiency
The water from the Seongjigok valley had previously flowed into the sewage treatment plant mixed with sewage, resulting in unnecessary treatment burdens. However, with the recent installation of the separation wall, a way has opened up to utilize the valley water directly.
This change is expected to have positive effects on various fronts. The water quality of the Dongcheon will improve, the self-purification ability will be enhanced, and the operating costs of the sewage treatment plant are expected to decrease. Furthermore, the improvement of the urban stream environment can also be enjoyed.
Future Plans
Based on the results of the Bujeon Stream project, Busan plans to expand the installation of rainwater and sewage separation walls in various tributary streams connected to the Dongcheon. This initiative aims to focus on continuous water quality improvement and the creation of a pleasant urban environment.
In particular, with the clear valley water flowing from Seongjigok into Dongcheon, it is expected that a water-friendly space will be created where citizens can enjoy a cleaner stream more closely. This is anticipated to bring about positive changes for the local residents.
Conclusion
The installation of the rainwater and sewage separation wall in the Bujeon Stream is an important project aimed at improving the city's water quality. As a result, the clean water from Seongjigok has begun to flow back into the Dongcheon.
Through this project, Busan plans to further enhance tributary stream management and facility improvements, striving to ensure that the Dongcheon develops into a clear and healthy urban stream.

Frequently Asked Questions (FAQ)
Q. What changes have occurred with the installation of the rainwater and sewage separation wall in Bujeon Stream?
The installation of the rainwater and sewage separation wall in Bujeon Stream allows clean valley water from Seongjigok to flow directly into Dongcheon.
The city of Busan has completed the installation of a rainwater and sewage separation wall in the covered area of Bujeon Stream, allowing clean valley water from Seongjigok to flow directly into Dongcheon without mixing with household sewage. This measure is expected to reduce the burden on sewage treatment and enhance the self-purification function of the stream, significantly contributing to water quality improvement.
Q. What are the main contents and schedule of this construction?
The project to install a rainwater and sewage separation wall over a 1.7km section in Busanjin-gu started in 2023 and is scheduled to be completed in September 2025.
The construction includes the installation of a rainwater and sewage separation wall from the Citizen Park in Busanjin-gu to Gwangmu Bridge, covering a distance of 1.7km, as well as the removal of sedimentation tanks and weirs. The total length of the separation wall is 3.5km, and the plan is to begin in 2023 and complete by September 2025. After completion, it is expected to alleviate odor problems and water quality pollution.
Q. What is the impact of valley water from Seongjigok on the water quality of Dongcheon?
Clear valley water from Seongjigok contributes to improving water quality and enhancing sewage treatment efficiency in Dongcheon.
By allowing valley water to flow directly, the self-purification function of Dongcheon is strengthened and the stream flow is supplemented, greatly contributing to water quality improvement. This also reduces the operational burden of the sewage treatment plant and is expected to improve the overall environment of urban streams.
Q. What are Busan's future plans regarding stream improvements?
Busan plans to expand the installation of rainwater and sewage separation walls to the tributary streams connected to Dongcheon.
Building on the results of the Bujeon Stream project, Busan aims to promote the installation of rainwater and sewage separation walls in other tributary streams, with the goal of achieving continuous water quality improvement and creating a pleasant urban environment. The influx of clean water is also expected to increase the use of water-friendly spaces by citizens.
Q. What is the purpose of the rainwater and sewage separation wall installation project in Bujeon Stream?
It aims to resolve structural issues for improving urban stream water quality and enhancing sewage treatment efficiency.
This project was pursued to alleviate pollution and odor problems in the covered Bujeon Stream, and it aims to contribute to urban environmental improvement by allowing clear valley water to flow directly into the stream. Separation of sewage and clear water is also expected to enhance the self-purification function of the stream and reduce sewage treatment costs.
