Facility Modernization and Master Plan
As part of Seoul’s future city planning, the city is implementing a facility modernization project at the Seonam Center.
The project involves demolishing outdated facilities and constructing new, underground water recycling facilities at the Seonam Center.
This will result in cleaner treated water, while the surface area will be transformed into a park open to the public.
The first phase of the modernization project, with a facility capacity of 360,000 m³/day, was completed in 2021.
