Sustainable Urban Wastewater Treatment Visualizations

Abstract

The handling and treatment of urban wastewater are essential to protecting human health and the environment. However, its existence and importance are mostly invisible to the general public. In this work, we present a set of visualization system designed to communicate and visually explore the wastewater treatment system of Vandcenter Syd (VCS), one of the largest water utilities in Denmark on the island Fyn. It operates eight wastewater treatments, and our solution enables geographically exploring and comparing data collected in different facilities with an interactive map. We further provide a set of interactive visual interfaces to support exploring the energy consumption and production trends over the past 10 years. A case study on Ejby Mølle, VCS's largest facility, illustrates its transition from an energy consuming into an energy producing facility.
