Abstract: Abstract This work applies a multi-criteria group decision-making (MCGDM) method to select the best treated wastewater reuse allocation alternative for augmenting water supply. The additive ratio compromise assessment (ARCAS) hybrid method is based on the integration of stepwise weight assessment ratio analysis (SWARA) (for weighting the criteria) with the adapted additive ratio assessment (ARAS) multi-criteria decision-making method in a group decision-making framework with new normalization scheme for the decision-making matrix̕s elements. For this purpose, four main criteria with 15 sub-criteria and six alternatives for treated wastewater reuse, i.e., landscape irrigation, agricultural irrigation, application in the industrial sector, artificial aquifer recharge, recreational sector, and supplying environmental demands are considered. Experts’ opinions are gathered and the steps of the ARCAS method are applied. The results show that the agricultural irrigation alternative is top ranked. The final ranking of the treated wastewater reuse alternatives is achieved by evaluating the alternatives and revising the criteria’s weights by the experts.
