Waterworks Museum

The starting point 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 Water Purification Plant No. 1 at Ttukdo Water Reservoir was built in 1980 when Emperor Gojong granted the patent right for the installation and management of waterworks to Americans Collbran and Bostwick. On September 1 of the same year, up to 12,500 tons of water was supplied to the residents in Yongsan and the area surrounded by the four gates of old Seoul. This marked the beginning of the history of waterworks services in Seoul.

Slow Filter Chamber

As the oldest steel-reinforced concrete structure that is present in Korea, it was used from 1908 to 1990. Upon its completion, this facility filtered impurities at a speed of approximately 4 m per day using an eco-friendly method based on sand and gravel. Together with the main building of the Waterworks Museum, it has been preserved as Tangible Cultural Heritage No. 72 designated by the Seoul Metropolitan Government.
