DP01520901_SESTO_S_GIOVANNI is a wastewater treatment plant located in Cologno Monzese, within the metropolitan area of Milan, in the Lombardy region of Italy. The plant serves a population of approximately 100,000, classifying it as a large agglomeration under EU regulations. Its location near the Tangenziale Nord di Milano places it in a densely populated and industrialized area. As a plant serving over 100,000 people, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum, and tertiary treatment if the receiving waters are sensitive. The directive also mandates that such plants meet specific effluent quality standards to protect the environment. The regulatory framework ensures appropriate treatment levels. The plant discharges into the local water system, which ultimately drains into the Po River basin, one of Italy's most significant watersheds. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic life and agricultural activities. The plant's operation is crucial for protecting the water quality of the Po basin and the Adriatic coastal ecosystem.

The plant is located in the Po River basin, which drains a large portion of northern Italy and flows into the Adriatic Sea. The Po River supports a rich ecosystem, including fish species and migratory birds, and its delta is an ecologically sensitive area. The plant's discharge contributes to the overall water quality of the basin, affecting downstream habitats and the Adriatic coastal environment.
