DP01910201_SPINO_D_ADDA Wastewater Treatment Plant, Spino d'Adda, Lombardy

DP01910201_SPINO_D_ADDA is a wastewater treatment plant located in Spino d'Adda, a town in the province of Cremona, Lombardy, Italy. The plant serves a population of approximately 7,875 residents, placing it in the small-to-medium agglomeration category under EU classification. As an Italian plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size discharging into freshwater. The directive also mandates appropriate treatment to protect the receiving environment, with potential for tertiary treatment if the area is designated as sensitive. The plant's treated effluent is discharged into the local water system, which ultimately drains into the Adda River, a major tributary of the Po River. The Po River basin is ecologically significant, supporting diverse aquatic life and agricultural activities in the Po Valley. Proper treatment helps protect downstream water quality and ecosystems.

The plant discharges into the Adda River, a tributary of the Po River, which flows into the Adriatic Sea. The Po Valley is a densely populated and agriculturally intensive region, making nutrient removal important to prevent eutrophication in the Adriatic. The local watershed supports diverse aquatic habitats and is a key corridor for migratory fish species.
