Jongno-gu, Seoul (District Mayor Jeong Munheon) announced on the 7th that it will apply new technology to the sewer pipeline repair work around Samcheong-ro and the National Museum of Modern and Contemporary Art area, and proceed with the repairs in the second half of this year.

The area around the National Museum of Modern and Contemporary Art is a popular destination for domestic and international tourists. Instead of digging up the road to repair the sewer, a trenchless (non-excavation) method will be applied, using compressed air and steam curing from underground machinery to repair the large sewer pipes.

The repair of sewer pipelines and manholes is a measure to prevent ground subsidence and sewer backflow caused by aging. The target area covers a total 1 km section from Bukchon-ro 5ga-gil to Changdeokgung-gil. To this end, the district secured a total of 600 million KRW in city funds.

District Mayor Jeong Munheon explained, “As concerns about road subsidence have increased, we will focus on carrying out the repair work of aging sewer pipelines, which are considered the main cause of subsidence, without any setbacks and on creating a safe and secure city.”
