’Water is Life’ - but what is wastewater?

Abstract

Water is our most precious food item. This article deals with water-related perceptions among residents and professionals and with the role of wastewater to mitigate supply of nutrients and water. The topic covers different times and different geographical areas with a focus on urban areas. Examples from Europe and Asian cities guide the text. The purpose is to enhance our understanding of why our cities are or aspire to become pipe-bound, despite that this leads to resource problems.
