    Abstract Treatment of wastewater for the purpose of reuse is a complex task. In addition to the national and international regulations and standards on water quality and treatment technology, there are many other constraints that need to be taken into account, such as the financial resources and the level of training of local operating personnel. In order to methodically simplify the selection process, an assessment tool was developed by the German Association for Water, Wastewater and Waste (DWA) in 2008. This assessment tool is presented as a matrix (DWA Matrix, hereafter) that takes a variety of wastewater treatment processes into account. Within the DWA Matrix, each step in a process is assessed with regard to a diverse number of aspects, such as, discharge quality, costs, consumption of material and energy, expenses for preventative maintenance, and so forth. The assessment conducted on individual treatment methods allows them to be compared with each other and gives information about the risks of individual processes related to the water reuse. The objective of this chapter is to present background information on the process, and then to discuss how the DWA Matrix can be used for water reuse applications specifically in agriculture.
