BAONE Wastewater Treatment Plant, Valle San Giorgio, Veneto, Italy

The BAONE wastewater treatment plant is located in Valle San Giorgio, a frazione of Baone in the Veneto region of northern Italy. This small-scale facility serves a population of 274 residents, reflecting its role in a rural or peri-urban setting within the Euganean Hills area. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent (PE) between 2,000 and 10,000. Although the plant's PE is below 2,000, Italy's national implementation extends secondary treatment to smaller communities to protect sensitive water bodies. The designed capacity of 500 m³/day and current discharge volume of 54.24 m³/day indicate ample capacity headroom. The treated effluent is discharged into local watercourses that drain into the Adige River basin, ultimately reaching the Adriatic Sea. The plant's operation helps safeguard the region's groundwater and surface water quality, supporting agricultural use and the ecological health of the Po Valley watershed.

The plant discharges into small streams that feed into the Adige River, one of Italy's major rivers flowing into the Adriatic Sea. The surrounding area includes the Euganean Hills Regional Park, a protected area with thermal springs and diverse habitats. The plant's secondary treatment reduces organic load and suspended solids, protecting downstream aquatic life and supporting the region's agricultural irrigation needs.
