The Busan Water Authority determined that the leak in a transmission pipeline installed in the floodplain area of the Nakdong River was causing difficulties in operating the water supply system and therefore decided to undertake emergency leak repairs.

To minimize inconvenience to residents that may arise during the water supply adjustment process, the Busan Water Authority plans to adjust valves gradually over four days beginning tomorrow, August 31, and carry out construction for eight days beginning September 4. During this period, it will continuously monitor changes in pipeline pressure and flow to check for any abnormalities and plans to restore the water supply system to normal around September 16.

Water supply adjustments will be made gradually to prevent problems such as discolored or turbid water that could occur due to changes in water velocity inside the pipeline caused by sudden valve adjustments.

The pipeline subject to this construction is a major transmission pipeline that delivers domestic water produced at the Deoksan Water Purification Plant to residents. It is a core facility responsible for more than 50 percent of Busan Metropolitan City’s total tap water supply. Its service area includes all of Jung-gu, Seo-gu, Dong-gu, Yeongdo-gu, Saha-gu, Gangseo-gu, and Sasang-gu; parts of Busanjin-gu, Dongnae-gu, Nam-gu, Buk-gu, Haeundae-gu, Geumjeong-gu, Yeonje-gu, and Suyeong-gu; parts of Gijang-gun; and the Busan New Port area in Jinhae-gu, Changwon.

Domestic water from the Deoksan Water Purification Plant system is currently supplied through two parallel pipelines, and this construction will be limited to a section of one of them. During the work, the Busan Water Authority plans to maintain water supply through the remaining pipeline, ensuring a stable supply of tap water without interruptions to individual households.

Domestic water from the Deoksan Water Purification Plant system is currently operated through two pipelines with diameters of 2,200 mm and 2,400 mm. During construction, supply will be consolidated through the 2,400 mm pipeline.

Industrial water produced at the Deoksan Water Purification Plant will continue to be supplied reliably without being affected by this water supply adjustment or construction work.

If residents experience any inconvenience with their water supply during the construction period, they may call the Busan Water Call Center at 051-120.

Kim Byung-gi, Director of the Busan Water Authority, said, “This leak repair work is being carried out on an emergency basis and is essential to ensure a safe supply of tap water. If temporary water supply inconvenience occurs during the adjustment process, we will provide prompt on-site response services through the relevant district service office.”
