San Secondo Parmense Wastewater Treatment Plant | Advanced Treatment in Emilia-Romagna

The San Secondo Parmense wastewater treatment plant is located in the town of San Secondo Parmense, in the Emilia-Romagna region of northern Italy. The facility serves a population of approximately 5,000 residents and is part of the municipal wastewater infrastructure for the area. The plant is situated in the Po River plain, an agriculturally intensive region with a dense network of canals and rivers. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant has a designed capacity of 8,000 cubic meters per day, with a reported discharge volume of about 913 cubic meters per day, indicating operational headroom. The treated effluent is discharged into local waterways that eventually drain into the Po River, Italy's longest river, which flows into the Adriatic Sea. The Po basin supports extensive agriculture, wetlands, and biodiversity. Advanced treatment helps reduce eutrophication risks in the Adriatic, a semi-enclosed sea sensitive to nutrient pollution.

The plant discharges into the Po River basin, which flows eastward through northern Italy and empties into the Adriatic Sea. The Po Delta is a ecologically significant area supporting diverse aquatic life and migratory birds. Advanced treatment at this plant helps control nutrient loads that could otherwise contribute to algal blooms and hypoxia in the Adriatic, a basin with limited water exchange.
