[Asia Economy Reporter Park Hyesook] Incheon City has unveiled a blueprint for expanding sewage treatment infrastructure.

The city announced on the 4th that the "2035 Sewerage Maintenance Master Plan," which includes increasing sewage treatment capacity and conducting a full inspection of aging pipelines, has received approval from the Ministry of Environment.

The Sewerage Maintenance Master Plan, with a total project cost of 6.47 trillion KRW, reflects various development plans such as the Incheon Urban Basic Plan and the Free Economic Zone, as well as recent changes in sewage-related indicators.

To proactively respond to the expected sewage volume due to continuous population growth and large-scale development projects in Songdo, Cheongna, and Geomdan, the city plans to increase the daily treatment capacity of 14 public sewage treatment facilities from the current 1.513 million tons to 1.809 million tons by 2035, an increase of about 20%.

Additionally, the Seunggi Sewage Treatment Plant, installed in 1995 and deteriorated due to aging facilities and inflow of wastewater from Namdong Industrial Complex causing reduced treatment capacity and odor issues, will undergo modernization through an underground construction method beneath the current site.

A park or sports facilities will be created on the newly constructed facility's upper area and the remaining site for use by nearby residents.

The city will also conduct a detailed inspection of 3,237 km (55.4%) of old pipelines that have been in place for over 20 years out of the total 5,843 km of sewage pipelines in the region by 2022, investing 22.5 billion KRW.

For the Gajwa Sewage Treatment Plant, where treatment efficiency has declined due to facility aging and high-concentration sewage inflow, 9.4 billion KRW will be invested to install pretreatment facilities by next year, and 37.9 billion KRW will be spent to increase the daily treatment capacity of the Gaja fecal treatment facility by 800 cubic meters.
