Waterworks Museum

The past, the present, and the future of Korea’s waterworks system –
The Waterworks Museum is where the dream of enriching Seoul begins!
As the first water purification plant in Korea, the Ttukdo Water Purification Plant was built in 1980 when Emperor Gojong granted the patent right for the installation and management of waterworks system to Americans Collbran and Bostwick. On September 1 of the same year, 12,500 tons of water was supplied to the residents in Yongsan and area surrounded by the four gates of old Seoul. This marked the beginning of waterworks service in Seoul.

The beautiful arch-shaped main entrance, built with granite and red bricks, is a characteristic feature of modern architectural design.

Slow Filter Chamber

As the oldest steel-reinforced concrete structure in Korea, it was used from 1908 to 1990. The slow filter chamber filtered microorganisms and other matter at low speed of approximately 4M per day. Together with the main building of the Waterworks Museum, it was designated as Tangible Cultural Heritage No. 72 by the Seoul Metropolitan Government.
