DP01504201_CALVIGNASCO Wastewater Treatment Plant, Casorate Primo, Lombardia

DP01504201_CALVIGNASCO is a municipal wastewater treatment plant located in Casorate Primo, in the Lombardia region of northern Italy. The plant serves a population of approximately 10,893 people, classifying it as a medium-sized agglomeration under Italian and EU regulations. As a plant in Italy, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treatment process and capacity details are not publicly available, but compliance with the directive ensures appropriate treatment standards. The treated effluent is discharged into the local water system, which ultimately drains into the Po River basin. The Po River is the longest river in Italy and flows into the Adriatic Sea, supporting diverse aquatic ecosystems and agricultural activities along its course. The plant plays a key role in protecting water quality in this densely populated and agriculturally important region.

The plant discharges into the Po River basin, which flows through northern Italy and empties into the Adriatic Sea. This watershed supports extensive agriculture and is home to diverse aquatic life, including fish species such as the European eel and various cyprinids. The Po Delta is an ecologically sensitive area that provides critical habitat for migratory birds and supports wetland ecosystems.
