Dorimcheon
Overview
Dorimcheon (도림천, 道林川) is a local stream that flows through Yeongdeungpo-gu and Guro-gu in Seoul and empties into the Han River. Its total length is approximately 12.5 km, and its watershed area covers 30.2 km². In the past, it served as a channel for agricultural water and domestic sewage, but after the 2000s, through an ecological stream restoration project, it was reborn as a resting place for citizens and a key axis of the urban ecosystem. Currently, walking paths and bicycle roads have been established along Dorimcheon, making it a green space in the daily lives of local residents.

Geographical Location and Course
Dorimcheon originates in the Sillim-dong area of Gwanak-gu and flows through Yeongdeungpo-gu and Guro-gu before joining the Han River. Major tributaries include Daebangcheon and Sinjeongcheon, which form the drainage systems of Yeongdeungpo-gu and Guro-gu, respectively. The upper section of the stream mainly passes through residential and commercial districts, while the middle and lower sections show an urban landscape mixed with industrial zones.
Historical Changes
During the Joseon Dynasty, wide agricultural fields spread around Dorimcheon, and it was used for agricultural water. During the Japanese colonial period and the industrialization era, water quality deteriorated sharply due to the inflow of factory wastewater and domestic sewage. In the 1970s and 1980s, urbanization led to the stream being covered or encased in concrete, destroying the ecosystem. From the late 1990s, awareness of environmental restoration increased, and in the early 2000s, in connection with Seoul's 'Cheonggyecheon Restoration Project,' Dorimcheon also began to be restored as an ecological stream.
Ecological Stream Restoration Project
The Dorimcheon ecological stream restoration project, carried out from 2005 to 2010, focused on enhancing biodiversity by removing concrete revetments, creating natural-type banks, planting aquatic plants, and installing fishways. Additionally, sewage treatment plants were expanded and the inflow of pollutants was blocked to improve water quality. Currently, various fish species such as carp, crucian carp, and crayfish, as well as aquatic insects, inhabit Dorimcheon, and fireflies can be observed in summer.
Citizen Use Facilities
Walking paths and bicycle roads totaling 15 km have been established along Dorimcheon, serving as spaces for exercise and leisure for citizens. In particular, the 'Dorimcheon Ecological Park' has been created in the Yeongdeungpo-gu section, functioning as a nature learning center. Benches, exercise equipment, and rest areas installed along the stream are popular as relaxation spaces for residents.
Water Quality Management and Flood Prevention
Dorimcheon frequently overflowed during heavy rains in the past, but flood damage has significantly decreased since the 2010s due to stream maintenance and the expansion of drainage pumping stations. Currently, Seoul City, Yeongdeungpo-gu, and Guro-gu jointly conduct water quality monitoring and monitor pollution sources in real time. Additionally, rainwater pumping stations and retention basins have been expanded to contribute to urban flood prevention.
Latest Trends
As of 2024, Dorimcheon is gaining attention as a model for 'Seoul-type ecological streams.' Seoul City plans to introduce a smart water quality management system for major streams, including Dorimcheon, by 2025. This system uses IoT sensors to measure water quality, water level, and flow velocity in real time and automatically responds when anomalies occur. In 2024, a project to create a 'Dorimcheon Cultural Belt' is underway, where cultural spaces, cafes, and galleries will be established along Dorimcheon as an 'urban regeneration hub.' Along with this, voluntary stream protection activities by local residents have become active, with the 'Dorimcheon Guardians' group regularly conducting stream cleanup activities and ecological education. To prepare for the increasing frequency of heavy rains due to climate change, construction to secure additional large-scale retention basins downstream of Dorimcheon is scheduled by 2025.
