DP01516901_PAULLO Wastewater Treatment Plant, Paullo, Lombardy, Italy

DP01516901_PAULLO is a municipal wastewater treatment plant located at 5, Via Caduti del Lavoro, in Paullo, a town in the Metropolitan City of Milan, Lombardy, Italy. The plant serves a population of approximately 13,656 people, classifying it as a medium agglomeration under EU regulations. As an Italian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Po River basin, one of Italy's most important hydrological systems. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic life and agricultural irrigation along its course. The plant plays a key role in protecting local water quality and the downstream environment.

The plant discharges into the local water network that feeds into the Po River basin, which ultimately drains into the Adriatic Sea. This watershed supports significant biodiversity and is used for agriculture, recreation, and drinking water supply. Protecting water quality in this basin is critical to prevent eutrophication and maintain ecological balance in the Adriatic coastal zone.
