An eco-efficiency evaluation of community-scale rainwater and stormwater harvesting in Aarhus, Denmark

Urban areas in Denmark are currently challenged by the increase in extreme precipitation events, resulting in heightened flood risk, and higher water stress caused by population growth. Therefore, we need to diversify water resources and reshape stormwater management. Our study evaluated the potential for increasing economic value while reducing the environmental impacts of implementing new concepts for non-potable rainwater use in a new urban...
