Annone Veneto Lorenzaga Wastewater Treatment Plant | Veneto, Italy

The Annone Veneto Lorenzaga wastewater treatment plant is located in the municipality of Annone Veneto, in the Veneto region of northeastern Italy. The plant serves a small community of approximately 2,006 residents, reflecting its role in managing domestic wastewater for this rural area. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,000 m³/day and an average daily discharge of 397.12 m³/day, the facility operates well within its capacity, ensuring effective treatment of incoming wastewater. The treated effluent is discharged into local water bodies that ultimately drain into the Adriatic Sea via the Venetian Lagoon or the Po River basin. The advanced treatment level helps protect the sensitive coastal and lagoon ecosystems, which are ecologically important for biodiversity and migratory species. The plant's inland location, more than 10 km from the coast, reduces direct marine discharge risks.

The plant discharges into local waterways that flow into the Venetian Lagoon and eventually the Adriatic Sea. This region supports diverse aquatic life and is an important migratory corridor for birds. The advanced treatment helps minimize nutrient loading, protecting the lagoon's delicate ecological balance and preventing eutrophication in downstream coastal waters.
