Frabosa Soprana Mondagnola Wastewater Treatment Plant, Piemonte, Italy

Frabosa Soprana Mondagnola is a municipal wastewater treatment plant located in the hamlet of Mondagnola, within the municipality of Frabosa Soprana in the province of Cuneo, Piemonte, Italy. The plant serves a population of approximately 4,353 people, classifying it as a small agglomeration under Italian and EU regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland freshwater discharges from agglomerations of this size. With a designed capacity of 4,800 cubic meters per day and an average daily discharge volume of about 894 cubic meters, the plant operates well within its capacity, ensuring effective treatment. The treated effluent is discharged into local streams that drain into the Po River basin, ultimately reaching the Adriatic Sea. This discharge supports the ecological health of the Po River system, which is vital for agriculture, biodiversity, and water supply in northern Italy. The plant plays a key role in protecting downstream water quality and aquatic habitats.

The plant discharges into small tributaries of the Po River, Italy's longest river, which flows eastward into the Adriatic Sea. The Po basin supports diverse aquatic life and is an important agricultural and industrial region. The secondary treatment provided helps reduce organic pollutants and nutrients, mitigating eutrophication risks in the Adriatic Sea. The surrounding area is characterized by Alpine foothills and mixed land use, including agriculture and small settlements.
