DP01501501_BASIGLIO Wastewater Treatment Plant, Milano 3, Lombardia, Italy

DP01501501_BASIGLIO is a wastewater treatment plant located in Milano 3, a locality within the municipality of Basiglio in the Lombardia region of northern Italy. The plant serves a population of approximately 8,912 people, classifying it as a small to medium agglomeration under EU regulations. Its location in the Po Valley places it within a densely populated and agriculturally intensive region. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent between 2,000 and 10,000 are required to have secondary treatment. For smaller plants like this, appropriate treatment ensures compliance with discharge standards. The regulatory framework sets clear expectations for performance. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Po River basin. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic ecosystems and providing water for irrigation and industry. The plant plays a role in protecting these downstream environments from nutrient pollution and pathogens.

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 ecosystem, including migratory fish species and extensive wetlands in its delta. The region is also a major agricultural area, making nutrient removal from wastewater critical to prevent eutrophication in the Adriatic. The plant's location in the Po Valley, a densely populated and industrialized area, underscores its importance in maintaining water quality.
