Borgolavezzaro Wastewater Treatment Plant, Borgolavezzaro, Piemonte, Italy

The Borgolavezzaro wastewater treatment plant is located in the town of Borgolavezzaro, in the province of Novara, within the Piemonte region of northwestern Italy. The plant serves a population equivalent of 8,201, classifying it as a small to medium agglomeration under EU regulations. As an Italian wastewater facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent between 2,000 and 10,000 discharging into freshwater or estuaries. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Po River basin, one of Italy's most important hydrological systems. The Po River flows eastward across northern Italy before entering the Adriatic Sea, supporting diverse aquatic life and agricultural irrigation along its course.

The plant discharges into the Po River basin, which drains a large portion of northern Italy and flows into the Adriatic Sea. The Po River and its tributaries support a rich ecosystem, including migratory fish species and extensive wetlands. The region's intensive agriculture and industrial activity make effective wastewater treatment critical for maintaining water quality and ecological balance in the downstream environment.
