dc.description.abstract	The increasing scarcity of water resources, exacerbated by climate change, calls for more sustainable and innovative approaches to water management. This study examines the feasibility and benefits of using Water for Reuse (WfR) for irrigation at the Polytechnic Institute of Viseu campus in Portugal. By using WfR, the university aims to reduce its reliance on potable water, promote sustainability, and enhance the resilience of its landscape management practices. However, assessing potential risks is crucial. Risks associated with the WfR from the Viseu Sul Wastewater Treatment Plant (WWTP) for green space irrigation on campus were evaluated, focusing on public health and water resource impacts. A semi-quantitative risk assessment methodology was applied, analysing microbiological, chemical, and physical parameters to ensure the treated water meets safety standards for its intended use. Three receptor groups were considered: maintenance workers, students/faculty, and visitors. Results showed the feasibility of producing and using WfR for irrigation, with the overall risk being below 3, considered negligible. The global public health risk was 0.72, with maintenance workers having the highest individual risk (0.75). The global risk for water resources was 2.30 for nitrogen and phosphorus, and 0.8 for microbiological risks. All risks were considered insignificant, making the use of WfR a viable and safe solution for sustainable water management.	por
