Replacement of 18km Aging Pipes to Resolve Water Supply Issues for 9,800 Households in Yongsan Haebangchon Area, Seoul

Replacement of Old Pipes Since 2006, Prevention of Leakage and Turbid Water Due to Increased Water Pressure
Separation of Water Supply Systems for Low and High Areas, Installation of New Pumps for Pressure Increase... Establishing a Stable Water Supply Environment

[Asia Economy Reporter Lim Cheol-young] The chronic water supply inconvenience in Haebangchon area of Yongsan 2-ga-dong, Yongsan-gu, the last low water output (少出水, phenomenon of low water flow) area in Seoul, is expected to be resolved.

On the 20th, the Seoul Metropolitan Waterworks Headquarters announced that they have resolved the water supply inconvenience by replacing 18 km of old pipes and establishing a customized water supply system reflecting the characteristics of the area. Yongsan 2-ga-dong, Huam-dong, and Itaewon 2-dong in Yongsan-gu, adjacent to Sowol-gil on the southwest side of Namsan, have a very large elevation difference of 83m (lowest 20m to highest 103m) between low and high areas, causing the so-called ‘low water output’ phenomenon due to low water pressure in the high area around the Yongsan 2-ga-dong Community Service Center.

On the other hand, in the low area near the Huam-dong Community Service Center, the water pressure was too high, affecting the old pipes within the water supply zone, raising concerns about pipe bursts, turbid water occurrence, and water quality accidents. Accordingly, the Waterworks Headquarters improved the water supply system by replacing old water pipes within the supply zone and establishing a customized water supply system reflecting the area's characteristics to resolve the water supply imbalance for 9,800 households in three districts of Yongsan 2-ga-dong area.

Seoul City has continuously replaced old pipes (18 km) in the target area since 2006 to prevent problems such as turbid water or leaks even when water pressure is increased, completing maintenance by the end of last year. The low area near Huam-dong Community Service Center was switched to supply from the nearby Namsan water reservoir system, fundamentally blocking the possibility of water quality accidents. A booster pump was installed at the Bogwang pumping station for the high area around Yongsan 2-ga-dong Community Service Center to solve the low water pressure problem, establishing a customized water supply system in the Haebangchon area.

Furthermore, to ensure stable water supply operation, the water pressure in the mid and high areas has been gradually increased step-by-step since the 10th, and monitoring of complaints in related areas confirmed the stability of water supply operation. It is expected that when the stepwise pressure increase is completed by the end of May, the water pressure in the mid and high areas will rise by an average of 1.7 kgf/cm², resolving the low water output issue.

Kim Tae-gyun, head of the Seoul Waterworks Headquarters, said, “Through this project, the chronic water supply inconvenience in the last low water output area in Seoul, Yongsan 2-ga-dong, is expected to be resolved,” and added, “We will strive to ensure that all citizens can use clear and clean tap water anytime and anywhere without inconvenience.”
