DP09802902_GUARDAMIGLIO Wastewater Treatment Plant, Guardamiglio, Lombardia

DP09802902_GUARDAMIGLIO is an advanced wastewater treatment plant located in Guardamiglio, a town in the Lombardia region of northern Italy. The plant serves a population of approximately 3,284 residents and has a designed capacity of 5,000 m³/day, with an average daily discharge volume of 650.12 m³. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Italy classifies sensitive areas requiring such treatment. For agglomerations of this size (under 10,000 PE), advanced treatment is typically mandated if the receiving waters are sensitive to eutrophication. The treated effluent is discharged into the local water system, which ultimately drains into the Po River basin. The Po River is Italy's longest river and flows into the Adriatic Sea. The plant plays a key role in protecting the Po River's water quality and the downstream ecosystems of the Po Delta, which supports diverse aquatic life and migratory bird populations.

The plant discharges into the Po River basin, which flows eastward through northern Italy and empties into the Adriatic Sea. The Po Delta is a ecologically sensitive area that supports diverse aquatic habitats and serves as an important migratory corridor for birds. Advanced treatment helps reduce nutrient loading, mitigating eutrophication risks in the Adriatic Sea.
