DEPURATORE SODARELLA Wastewater Treatment Plant, Vitorchiano, Lazio, Italy

DEPURATORE SODARELLA is a wastewater treatment facility located in the Sodarella area of Vitorchiano, a town in the province of Viterbo, Lazio, Italy. The plant serves a small population of 330 residents, reflecting its role in a rural or peri-urban setting within the Italian region. 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. With a designed capacity of 400 cubic meters per day and an actual discharge volume of 65.33 cubic meters per day, the facility operates well below its capacity, indicating room for future growth or seasonal demand. The treated effluent is discharged into the local watershed, which ultimately drains into the Tiber River basin. The Tiber River flows through Lazio and into the Tyrrhenian Sea near Rome. The advanced treatment level helps protect the Tiber's water quality and the downstream marine environment, supporting aquatic life and reducing nutrient loading.

The plant discharges into the Tiber River basin, which flows through central Italy and empties into the Tyrrhenian Sea. The Tiber is a major river supporting diverse aquatic ecosystems and providing water for agriculture and urban use. Advanced treatment at this plant helps minimize nutrient and pollutant loads, protecting the river's ecological health and the coastal waters of the Tyrrhenian Sea.
