Abstract(s)
Due to the growing water scarcity, the reuse of treated wastewater arises as a possibility for sustainable
water management. However, it is necessary to evaluate the possible risks associated with its activity.
This study aims to develop a risk assessment of water for reuse, in terms of public health and water
resources, for production and internal use by the Viseu Sul Wastewater Treatment Plant (WWTP) and
external use in irrigation of green spaces in Viseu. The methodology used was a semi-quantitative risk
assessment. The results demonstrated the viability of the production and use of Reused Water by the
Viseu Sul WWTP, with an overall risk to public health of 0.68, and for use in irrigating green spaces in
Viseu, with an overall risk of 0.75. The overall risk to water resources was 2.33 for nitrogen and phosphorus and 0.78 for E. coli. All risks were considered insignificant, considering the criteria defined by the method. Based on the information presented, it can be inferred that the use of treated wastewater to meet Viseu's water needs is a viable option.
