Sources: 5. Developments: 2. Gunpo City is addressing urban safety and water management through ecological restoration and infrastructure upgrades. A policy forum was held to discuss the ecological restoration of the Sanboncheon Stream, which aims to remove concrete covers to improve water quality and mitigate the urban heat island effect. Experts noted that the current covered structures contribute to sediment accumulation and pose flood risks during extreme rainfall. To secure funding, the restoration plan must be integrated into the Gyeonggi Provincial River Basic Plan. In a separate infrastructure initiative, the city has launched a 29.6 billion won sewage pipe renovation project. This third phase aims to replace or repair 21.5 kilometers of sewage pipes older than 20 years across several areas, including Sanbon and Dangjeong. The project, funded by national, provincial, and municipal sources, is scheduled for completion by 2028 to prevent sinkholes and improve urban drainage capacity. ## Timeline ### 2026-11-03: Gunpo City launches 29.6 billion won sewage pipe renovation project Gunpo City is investing 29.6 billion won to repair 21.5km of aging sewage pipes by 2028 to prevent sinkholes and flooding. 3 sources. https://clstr.news/cluster/gunpo-city-launches-296-billion-won-sewage-pipe-renovation-project ### 2026-10-29: Gunpo City discusses Sanboncheon Stream ecological restoration Gunpo officials and experts are discussing the ecological restoration of the Sanboncheon Stream to mitigate flood risks and urban heat caused by its current concrete-covered state. 2 sources. https://clstr.news/cluster/gunpo-city-discusses-sanboncheon-stream-ecological-restoration --- Cite as: Gunpo City urban water management and infrastructure.
