DP02006601_VIADANA_GERBOLINA Wastewater Treatment Plant, Viadana, Lombardy

DP02006601_VIADANA_GERBOLINA is an advanced wastewater treatment plant located in Viadana, a town in the Lombardy region of northern Italy. The facility serves a population of approximately 2,005 residents, classifying it as a small agglomeration under EU standards. Its location in the Po River basin places it within a densely populated and agriculturally intensive 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The designed capacity is 2,000 m³/day, with a reported discharge volume of 396.92 m³/day, indicating operational headroom. Treated effluent is discharged into local waterways that ultimately drain into the Po River, Italy's longest river, which flows into the Adriatic Sea. The Po basin supports extensive agriculture and is ecologically significant, hosting diverse aquatic life. The plant's advanced treatment helps reduce nutrient loading, mitigating eutrophication risks in the Adriatic coastal zone.

The plant discharges into the Po River basin, which drains into the Adriatic Sea. The Po River is a major ecological corridor supporting diverse fish species and migratory birds. Advanced treatment at this plant reduces nitrogen and phosphorus loads, helping to prevent algal blooms and oxygen depletion in the Adriatic coastal waters, which are sensitive to eutrophication.
