This paper presents the use of two Multi-Criteria Decision Analysis (MCDA) tools with Fuzzy Set Theories, namely Fuzzy Analytical Hierarchical Process (FAHP) and Fuzzy Technique for Order Preference by Similarity to the Ideal Solution (FTOPSIS), for aiding experts on the selection of the most sustainable wastewater treatment technology (WWT). 8 experts with different roles on the selection of WWT was invited to provide inputs. The selection process integrated sustainability by considering 4 major criteria Economical, Environmental, Social and Technical each then having its own sub-criteria.
