Despite the availability of suitable technologies, several constraints often prevent stakeholders and especially decision makers exploiting their potential. In this paper we present the results of applying a decision support tool (DST) to evaluate water reclamation, support pre-feasibility studies and build capacity for water reclamation in Vietnam. The DST and its data are open access, providing information related to local and international water and wastewater quality standards. In this research we identified high potential Vietnamese case studies and conducted a systematic PISTLE analysis considering six dimensions (Political, Institutional, Social, Technical, Legal and Economic) at a multiple local stakeholder workshop. Key barriers and drivers for water reclamation implementation were identified. Measures proposed during the workshop could serve as a starting point for the development of water reclamation projects in Vietnamenwater reusewastewater recyclingwater reclamationdecision support toolwater resources managementmulti-criteria analysisVietnam01A - Beitrag in wissenschaftlicher Zeitschrift65-73
