DP02003702_MOTTEGGIANA Wastewater Treatment Plant, Zaragnino, Lombardia

DP02003702_MOTTEGGIANA is an advanced wastewater treatment plant located in Zaragnino, a locality within the municipality of Motteggiana, in the province of Mantova, Lombardia, Italy. The plant serves a population equivalent of 1,285 and has a designed capacity of 1,350 cubic meters per day, with a reported discharge volume of 254.38 cubic meters per day. 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 requires appropriate treatment for discharges to sensitive areas, and advanced treatment is typical for plants serving agglomerations of this size in sensitive catchments. The treated effluent is discharged into local watercourses that ultimately drain into the Po River basin, one of Italy's most important hydrological systems. The Po River flows eastward into the Adriatic Sea, supporting extensive agricultural activity and diverse aquatic ecosystems. The plant's advanced treatment helps protect downstream water quality in this ecologically significant region.

The plant discharges into the Po River basin, which drains into the Adriatic Sea. The Po River is Italy's longest river and supports a rich variety of aquatic life, including fish species such as sturgeon and eel. The surrounding Lombardia region is intensively farmed, making nutrient removal from wastewater critical to prevent eutrophication in the Adriatic Sea.
