URBISAGLIA_MAESTA_UBS_DEP - Advanced Wastewater Treatment in Urbisaglia, Marche, Italy

URBISAGLIA_MAESTA_UBS_DEP is an advanced wastewater treatment plant located in Urbisaglia, a town in the Marche region of central Italy. The facility serves a population of approximately 3,014 and is situated along Strada Provinciale 83 Montedoro in the Maestà area. It operates as part of the municipal wastewater infrastructure for Urbisaglia and the surrounding communities. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 15,000 m³/day and a current discharge volume of 596.67 m³/day, the facility operates well below its capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size are required to provide secondary treatment, but the advanced level here indicates a higher standard, likely due to the sensitivity of the receiving environment. The treated effluent is discharged into local watercourses that drain into the Adriatic Sea via the Potenza River basin. The Marche region features a hilly terrain with rivers flowing eastward to the coast. The plant's advanced treatment helps protect downstream aquatic ecosystems and the coastal waters of the Adriatic, which support diverse marine life and are important for tourism and fisheries.

The plant discharges into the Potenza River basin, which flows eastward through the Marche region and empties into the Adriatic Sea. The Adriatic Sea is a semi-enclosed basin with sensitive ecosystems, including seagrass meadows and nursery areas for fish. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in coastal waters and supporting the ecological health of the river and marine environments.
