- Abstract
Urban wastewater reuse for urban public non potable uses, compatible with the obtained water quality, is increasingly considered as a viable option. However, several criteria need to be taken into account in the assessment of each application's viability. Therefore, an evaluation of different water reuse options needs to be accomplished, incorporating various points of view, namely, technological, functional, economic, public health, environmental, social, legal and institutional criteria. Thus, a methodology was defined, making use of multi-criteria decision support systems, in this case WTRNet and M-MACBETH, while incorporating a public health and environmental risk assessment. The methodology was applied to the case study of the Beirolas wastewater system, serving the municipalities of Loures and Lisbon, in Portugal. In the aftermath, viability analysis' results lead to a hierarchy of the identified water reuse alternatives, namely, and by order of preference: restricted landscape irrigation, non restricted landscape irrigation, sewer flushing, street cleaning, vehicle washing, fire fighting and ornamental use.
