CAPOLUOGO Wastewater Treatment Plant, Rieti, Lazio, Italy

CAPOLUOGO is an advanced wastewater treatment plant located in Poggio Fidoni, near Rieti, in the Lazio region of Italy. The facility serves a population of approximately 3,010 and has a designed capacity of 3,100 cubic meters per day, with an average discharge volume of 595.87 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a small agglomeration in Italy, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on the sensitivity of the receiving waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Tiber River basin. The Tiber River flows through central Italy and empties into the Tyrrhenian Sea near Rome. The plant's advanced treatment helps protect the ecological health of the Tiber River and its downstream environments.

The plant discharges into the Tiber River basin, which flows through Lazio and Umbria before reaching 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 loading, helping to prevent eutrophication in the river and coastal waters.
