DP01207301_GAZZADA_SCHIANNO Wastewater Treatment Plant, Gazzada Schianno, Lombardia

DP01207301_GAZZADA_SCHIANNO is an advanced wastewater treatment plant located in Gazzada Schianno, a municipality in the province of Varese, Lombardia, Italy. The plant serves a small population equivalent of 600, reflecting its role in a rural or peri-urban setting. Its location in the Po Valley places it within a densely populated and economically active region of northern Italy. The plant provides advanced treatment, which goes beyond the secondary treatment standard 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 receiving waters. The designed capacity is 300 m³/day, and the current discharge volume is 118.78 m³/day, indicating operational headroom. The treated effluent is discharged into local watercourses that ultimately drain into the Po River basin and then into the Adriatic Sea. The plant's advanced treatment helps safeguard downstream ecosystems, including the Po Delta, which supports diverse aquatic life and is an important migratory corridor for birds.

The plant discharges into local streams that feed into the Olona River or other tributaries of the Po River basin. The Po River flows eastward across northern Italy to the Adriatic Sea, forming a large delta that is ecologically sensitive and supports diverse aquatic life. Advanced treatment at this plant reduces nutrient loading, helping to mitigate eutrophication risks in the Po Delta and coastal Adriatic waters.
