The name 'Piano' refers to the architectural silhouette of the facility's main structure.
The site was established to change public perception of sewage treatment facilities as unpleasant or hidden urban utility zones.
It is integrated with an eco-park that includes a pedestrian bridge and observation decks for viewing the cascading water.
The waterfall is part of a larger facility that includes the Namyangju Environmental Experience Center.
Piano Falls is an artificial waterfall located within the Hwado Sewage Treatment Plant in Namyangju-si, Gyeonggi-do. The waterfall is constructed using treated water discharged from the facility, showcasing an innovative use of urban infrastructure for public leisure. Standing 61 meters wide and 91.7 meters high, the structure is designed to mimic the shape of a grand piano. It operates by pumping treated water to a height of 12 meters before allowing it to cascade down, creating a continuous flow throughout the warmer months. The site includes an environmental park, a fountain, and educational facilities aimed at promoting awareness of water purification processes. It serves as a unique example of turning industrial wastewater treatment plants into community-oriented public spaces.
