strategic solution in improving water supplies across the globe; however, there are still
various challenges that should be overcome. Selection of practical solutions is then
required whilst considering technical, environmental, socio-cultural, and financial factors.
In this study, a multi expert decision support tool that considers a variety of evaluation
criteria is proposed to provide a ranking system for competing advanced WWT
technologies in terms of their performance. Two scenarios of water reuse in the contexts
of Brazil and Greece are defined, and evaluation is undertaken based on opinions of
water reuse experts. The results prove that the tool would successfully facilitate rigorous
and methodical analysis in evaluation of WWT technologies for water reuse applications
with potential for use under various sets of evaluation criteria, WWT technologies and
contexts
