Borghetto Borbera Wastewater Treatment Plant, Borghetto di Borbera, Piemonte

The Borghetto Borbera wastewater treatment plant is located in Borghetto di Borbera, a town in the province of Alessandria, Piemonte, Italy. The facility serves a population of approximately 1,350 people and operates under Italian and EU regulations for small agglomerations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater bodies from agglomerations of this size. The plant has a designed capacity of 5,100 cubic meters per day, with an average daily discharge volume of 563 cubic meters, indicating ample reserve capacity. The treated effluent is discharged into local streams that eventually flow into the Scrivia River, a tributary of the Po River. The Po River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry in northern Italy. The plant's secondary treatment helps protect these water bodies from organic pollution.

The plant discharges into small watercourses that drain into the Scrivia River, a tributary of the Po River. The Po River flows eastward across northern Italy to the Adriatic Sea, forming one of Europe's most important river basins. The Scrivia and Po rivers support diverse aquatic ecosystems, including fish species such as barbel and chub, and provide habitat for migratory birds. The region's agricultural and industrial activities depend on good water quality, making the plant's treatment role critical.
