AMELIA_PATICCHI Wastewater Treatment Plant, Amelia, Umbria, Italy

AMELIA_PATICCHI is an advanced wastewater treatment plant located in Amelia, a town in the Umbria region of central Italy. The plant serves a population of approximately 4,043 people, reflecting its role in managing municipal wastewater for this historic hilltop community. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 8,500 cubic meters per day and a current discharge volume of 800.37 cubic meters per 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 Tiber River basin, which flows through Umbria and Lazio before reaching the Tyrrhenian Sea near Rome. The plant's advanced treatment helps protect the Tiber River and downstream ecosystems, including the coastal waters of the Tyrrhenian Sea, from nutrient pollution and other contaminants.

The plant discharges into the Tiber River basin, which flows through central Italy and ultimately reaches the Tyrrhenian Sea. The Tiber River supports diverse aquatic life and is an important water resource for agriculture and urban areas. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream waters and protecting the ecological health of the river and coastal zone.
