DP01708601_ISORELLA Wastewater Treatment Plant, Isorella, Lombardy, Italy

DP01708601_ISORELLA is an advanced wastewater treatment plant located in Isorella, a municipality in the province of Brescia, Lombardy, Italy. The plant serves a population equivalent of 3,859 and has a designed capacity of 2,500 cubic meters per day, with an actual discharge volume of 763.95 cubic meters per day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant's scale places it in the small agglomeration category, for which the directive mandates appropriate treatment to protect receiving waters. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Po River basin, which flows into the Adriatic Sea. This region is agriculturally intensive, and advanced treatment helps mitigate nutrient loading that could contribute to eutrophication in downstream waters.

The plant discharges into the Po River basin, which drains into the Adriatic Sea via the Po Delta. The Po River is Italy's longest river and supports diverse aquatic life, including migratory fish species. Advanced treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream ecosystems from eutrophication and maintaining water quality in the sensitive Adriatic coastal zone.
