LEGNAGO_PORTO Wastewater Treatment Plant, Legnago, Veneto, Italy

LEGNAGO_PORTO is a wastewater treatment plant located in Legnago, a town in the Veneto region of northern Italy. The plant serves a population of approximately 6,890 people, classifying it as a small to medium agglomeration under Italian and EU regulations. It is situated in the Po River basin, which is the largest river system in Italy. As an Italian plant serving fewer than 10,000 population equivalent, LEGNAGO_PORTO is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on the sensitivity of the receiving waters. For smaller agglomerations, secondary treatment is typically mandated, though specific treatment levels may vary depending on local environmental conditions and regulatory designations. The plant's treated effluent ultimately drains into the Po River, which flows eastward into the Adriatic Sea. The Po basin supports extensive agriculture and diverse aquatic ecosystems, including fish species such as sturgeon and eel. Proper wastewater treatment is critical to prevent nutrient loading and protect the ecological health of the river and its delta.

LEGNAGO_PORTO discharges into the Po River basin, which drains into the Adriatic Sea via the Po Delta. The Po River is Italy's longest river and supports a rich ecosystem, including migratory fish and waterfowl. The delta region is ecologically sensitive, with wetlands that provide critical habitat for birds and aquatic life. Effective treatment helps mitigate eutrophication risks in the Adriatic coastal zone.
