FRAZ_CIVITELLA Wastewater Treatment Plant, Pagliara, Lazio, Italy

FRAZ_CIVITELLA is a wastewater treatment plant located in Pagliara, a frazione of Pescorocchiano in the province of Rieti, Lazio, Italy. The plant serves a small population of 190 people and has a designed capacity of 300 cubic meters per day, with an average discharge volume of 37.61 cubic meters per day. The plant employs advanced treatment processes, which go beyond the minimum secondary treatment 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 treated effluent is discharged into the local water system, which ultimately drains into the Salto River, a tributary of the Velino River, and then into the Nera River, a major tributary of the Tiber River. The Tiber flows through Rome and into the Tyrrhenian Sea. The advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the Tiber basin.

The plant discharges into the Salto River basin, part of the larger Tiber River watershed. The Tiber flows through central Italy and empties into the Tyrrhenian Sea near Rome. The downstream environment includes ecologically sensitive areas such as the Tiber River estuary, which supports diverse aquatic life and migratory bird species. Advanced treatment at this plant reduces nutrient pollution, helping to prevent eutrophication in the river and coastal waters.
