This comprehensive study is the first to quantify nationwide the relative contribution of wastewater effluents to streams under varying discharge conditions and to provide an impact assessment of de facto reuse for downstream drinking water abstraction via bank filtration or aquifer recharge for selected case study areas in Germany.
Risk Management for Drinking Water Production in a Partially Closed Water Cycle – The Berlin Case

A substantial part of Berlin’s drinking water is produced from groundwater influenced by surface water with relevant shares of treated waste water. Thus, risk management needs to take into account the performance of different barriers towards waste-water-related contaminants. This paper describes the approach of Berliner Wasserbetriebe to manage the risks related to the semi-closed water cycle.
Safe wastewater reuse in the United Arab Emirates; safety assessment from concept to realisation

Fujairah in the United Arab Emirates wants to reuse wastewater for irrigation. We've developed a stepwise approach to assess safety from the first concept, through evaluation and inspection of the existing system, the technical designs, validation, verification up to the final operation under a sanitation safety plan. It provides a an example how to approach safe water reuse, especially in a context where national guidelines have not been established.
Water reuse as a sustainable water scarcity risk reduction measure: Integrating risk and sustainability assessment frameworks

The following abstract outlines the conceptual integration of risk and sustainability assessment frameworks to evaluate water reuse measures. The aim is to explore how risk and sustainability assessment can be integrated to tackle water reuse as a means of risk reduction under conditions of water scarcity.
