DP01813111_ROVESCALA_ROVESCALA_NORD Wastewater Treatment Plant, Rovescala, Lombardy

DP01813111_ROVESCALA_ROVESCALA_NORD is an advanced wastewater treatment plant located in the hamlet of Croce, near Rovescala, in the province of Pavia, Lombardy, Italy. The plant serves a small population of 89 residents, reflecting the rural character of the area. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets treatment standards based on agglomeration size and receiving water sensitivity. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU directive for agglomerations under 2,000 population equivalent. This level of treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The designed capacity is 89 cubic meters per day, and the current discharge volume is 17.62 cubic meters per day, indicating ample reserve capacity. The treated effluent is discharged into local watercourses that drain into the Po River basin, one of Italy's most important watersheds. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic life and agricultural irrigation. The advanced treatment helps minimize nutrient loading, protecting downstream ecosystems and the Adriatic coastal zone from eutrophication.

The plant discharges into small streams that feed into the Po River basin, which ultimately drains into the Adriatic Sea. The Po River is the longest river in Italy and supports a rich ecosystem, including migratory fish species and extensive wetlands. The advanced treatment at this plant reduces nutrient and pollutant loads, helping to maintain water quality in the Po basin and prevent eutrophication in the Adriatic Sea.
