FOSSO BACILE MLP DEP Wastewater Treatment Plant, Montelupone, Italy

FOSSO BACILE MLP DEP is an advanced wastewater treatment facility located in Montelupone, in the Marche region of Italy. The plant serves a population of approximately 1,221 people, reflecting its role in managing domestic wastewater for this small agglomeration. Its designed capacity of 1,600 m³/day indicates infrastructure sized for local needs, with current discharge volumes well below that threshold. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment is typically implemented in sensitive areas to reduce nutrient loads and protect receiving water bodies. The facility operates under Italy's national implementation of the directive, which mandates compliance with stringent effluent quality standards. Situated near the Adriatic coast, the plant discharges treated wastewater into local watercourses that ultimately drain into the Adriatic Sea. The proximity to the coast (within 10 km) underscores the importance of advanced treatment in safeguarding coastal water quality and marine ecosystems. The plant's operation supports the ecological health of the Adriatic basin, a region known for its biodiversity and tourism value.

The plant discharges into small streams in the Fosso Bacile area, which flow toward the Adriatic Sea. The Adriatic Sea is a semi-enclosed basin with limited water exchange, making it sensitive to nutrient pollution from coastal discharges. Advanced treatment at this plant helps reduce nitrogen and phosphorus loads, mitigating eutrophication risks in coastal waters and supporting marine life, including seagrass meadows and fish nurseries.
