Depuratore Campolimpido - Advanced Wastewater Treatment in Tivoli, Lazio, Italy

Depuratore Campolimpido is a municipal wastewater treatment facility located in Tivoli, within the Lazio region of Italy. The plant serves a population of approximately 4,200 residents and is situated inland, away from coastal areas. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment of wastewater. The plant employs advanced treatment processes, going beyond the secondary treatment required by the EU directive for agglomerations of this size. With a designed capacity of 6,230 m³/day and an actual discharge volume of 831.45 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The advanced treatment level ensures high-quality effluent suitable for sensitive environments. The treated wastewater is discharged into local water bodies that ultimately drain into the Tiber River basin, which flows through Rome and into the Tyrrhenian Sea. This makes the plant's performance important for protecting the Tiber's water quality and the downstream marine ecosystem. The advanced treatment helps reduce nutrient loads and pollutants, supporting aquatic life and recreational uses.

The plant discharges into the Tiber River basin, which flows through Rome and empties into the Tyrrhenian Sea. This watershed supports diverse aquatic habitats and is used for irrigation, recreation, and drinking water supply downstream. The advanced treatment level helps minimize eutrophication risks and protects sensitive species in the river and coastal zone.
