Overview
Osteria Nuova is an advanced wastewater treatment plant serving 4,200 people in Roma, Lazio, Italy. It discharges 831.45 m³/day of treated effluent into the local water system.
Osteria Nuova is an advanced wastewater treatment plant located in the Cesano district of Roma, in the Lazio region of Italy. The plant serves a population of approximately 4,200 people, classifying it as a small agglomeration under Italian and EU regulations. It is situated along Via Braccianese, about 8.5 km from the town center, and operates as part of the municipal wastewater infrastructure for the Roma Capitale area. 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 4,200 m³/day and an actual discharge volume of 831.45 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The facility is not located within 10 km of the coast but is within 50 km, meaning its effluent ultimately reaches the Tyrrhenian Sea via inland waterways. The treated wastewater from Osteria Nuova is discharged into local water bodies that drain toward the Tyrrhenian Sea. The plant plays a key role in protecting the Tiber River basin and the coastal marine environment from nutrient pollution and pathogens. Its advanced treatment ensures high-quality effluent, supporting aquatic life and recreational uses downstream. The facility contributes to the ecological health of the Lazio region, which includes sensitive coastal lagoons and marine habitats.
Environmental context
The plant discharges into local streams that feed into the Tiber River basin, which flows into the Tyrrhenian Sea near Rome. The Tiber River supports diverse aquatic life and is an important migratory corridor for fish species. The downstream coastal area includes ecologically sensitive marine habitats that benefit from the advanced treatment reducing nutrient loads and pollutants.
