BERRA Wastewater Treatment Plant, Berra, Emilia-Romagna, Italy

The BERRA wastewater treatment plant is located in Berra, a town in the Emilia-Romagna region of northern Italy. It serves a population of approximately 2,002 people, making it a small-scale municipal facility. The plant is situated inland, about 50 km from the Adriatic coast, and operates within the Po River basin. The plant employs advanced treatment processes, which go 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 2,500 cubic meters per day and currently treats an average daily flow of 556.11 cubic meters, indicating ample reserve capacity. 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 Delta is a ecologically significant area, supporting diverse aquatic life and serving as a key migratory corridor for birds. The plant's advanced treatment helps reduce nutrient loading, contributing to the health of the Po River and the Adriatic coastal ecosystem.

The BERRA plant discharges into the Po River basin, which flows eastward through northern Italy and empties into the Adriatic Sea via the Po Delta. The delta is a ecologically sensitive area that supports diverse aquatic life, including fish and bird species, and serves as an important migratory corridor. Advanced treatment at the plant helps minimize nutrient pollution, protecting downstream water quality and the fragile coastal environment.
