VEDELAGO_VIA_PIAVE Wastewater Treatment Plant, Vedelago, Veneto, Italy

The VEDELAGO_VIA_PIAVE wastewater treatment plant is located in Vedelago, a town in the Veneto region of northeastern Italy. It serves a small population of 724 residents, reflecting its role as a local facility for a rural community. The plant operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment of urban wastewater. The plant employs advanced treatment processes, going beyond the secondary treatment required by the EU directive for agglomerations of this size. Its designed capacity is 2250 m³/day, while the average daily discharge volume is 143.33 m³/day, indicating a utilization rate well below capacity. This suggests the plant is sized to accommodate future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the Adriatic Sea via the Venice Lagoon system. The plant's advanced treatment helps protect the sensitive lagoon ecosystem, which supports diverse aquatic life and is an important migratory corridor for birds. By providing high-quality effluent, the facility contributes to the environmental health of the downstream watershed.

The plant discharges into the local drainage network that feeds into the Sile River basin, which flows into the Venice Lagoon and then the Adriatic Sea. The Venice Lagoon is a shallow coastal lagoon of high ecological value, supporting diverse aquatic habitats and serving as a critical stopover for migratory birds. Advanced treatment at this plant helps reduce nutrient loads that could contribute to eutrophication in the lagoon's sensitive ecosystem.
