Even if Sweden is historically regarded as a water-affluent country, lately sustainable water use and water circularity have become topics of high concern. Irrigation is dependent on high quality water resources, and the need for accessible water resources becomes stronger under exceptionally dry conditions, when crop loss and stress on drinking water are strongly felt at multiple parts of the country. In this project we address the question of treated urban wastewater quality, and how does the effluent water from different treatment plants compares with the EU regulations on irrigation with treated wastewater (TW). We also study the response of the plants and crop quality to irrigation with TW, in controlled field experiments. The project results can serve as a practical guideline for agricultural producers and wastewater treatment plants.
