PASSO_DEL_BIDOLLO_MCR_DEP - Advanced Wastewater Treatment Plant in Corridonia, Italy

PASSO_DEL_BIDOLLO_MCR_DEP is an advanced wastewater treatment plant located in Passo del Bidollo, Corridonia, in the Macerata province of Italy. The plant serves a population of 924 and has a designed capacity of 750 m³/day, with a discharge volume of 182.92 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires advanced treatment for sensitive areas and agglomerations above 10,000 population equivalent. Although this plant serves a smaller population, its advanced treatment level indicates a commitment to high effluent quality. The treated wastewater is discharged into the local water system, which ultimately drains into the Adriatic Sea via the Potenza River basin. The region's proximity to the Adriatic coast (within 50 km) underscores the importance of advanced treatment to protect coastal water quality and marine ecosystems.

The plant discharges into the Potenza River basin, which flows into the Adriatic Sea. The Adriatic Sea is a semi-enclosed basin with limited water exchange, making it sensitive to nutrient pollution. Advanced treatment at this plant helps reduce the risk of eutrophication and supports the health of coastal habitats and fisheries in the region.
