Konzepte zur Wiederverwendung von aufbereitetem Abwasser im Unteren Jordantal

Treated wastewater is becoming increasingly important as a usable water resource, especially in areas of extreme water scarcity. The alternative water production and transfer strategies proposed in the SALAM-initiative to address the water deficit problem in the Middle East by providing fresh water from desalination plants show that significant amounts of additional wastewater would be generated in 2050. In this study, the potential for reuse of treated wastewater in the Lower Jordan Valley is investigated considering three reuse variants. The results show that there is a significant demand for irrigation purposes in agriculture, but also aquifer storage via managed aquifer recharge, or rehabilitation of Jordan River floodplains, are promising reuse options. The study demonstrates a combined approach of hydrogeological and land use analyses to quantify the different wastewater reuse concepts and provides a basis for further research and implementation plans for sustainable combined wastewater-groundwater management in the Lower Jordan Valley in Jordan.
