Osasco San Secondo Prarostino Wastewater Treatment Plant, Osasco, Italy

The Osasco San Secondo Prarostino wastewater treatment plant is located in Osasco, a town in the Piemonte region of Italy. It serves a population of about 4,763, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. As a small agglomeration, the plant is expected to provide secondary treatment in accordance with the EU UWWTD, which sets minimum standards for wastewater treatment across member states. The directive requires secondary treatment for all agglomerations above 2,000 population equivalent, with more stringent requirements for sensitive areas. The plant's design and operational practices align with these regulatory frameworks to ensure environmental protection. The treated effluent from the plant is discharged into local water bodies that eventually drain into the Po River basin, one of Italy's major river systems. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic life and agricultural activities along its course. The plant plays a crucial role in maintaining water quality in this ecologically important watershed.

The plant discharges into local waterways that are part of the Po River basin, which drains into the Adriatic Sea. The Po River is a vital water resource for northern Italy, supporting agriculture, industry, and biodiversity. The downstream environment includes sensitive aquatic habitats that rely on effective wastewater treatment to prevent nutrient pollution and maintain ecological balance.
