DEP_COM_VILLAGGIO_ADRIANO Wastewater Treatment Plant, Tivoli, Lazio, Italy

DEP_COM_VILLAGGIO_ADRIANO is an advanced wastewater treatment plant located in Tivoli, within the Lazio region of Italy. The facility serves a population of approximately 1,000 people and has a designed capacity of 1,000 cubic meters per day, with a discharge volume of 197.96 cubic meters per day. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting the stringent requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC). For small agglomerations like this, the directive mandates appropriate treatment to protect receiving water bodies, and advanced treatment is often required in sensitive areas. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Tyrrhenian Sea via the Aniene River and the Tiber River. The facility plays a key role in protecting the water quality of these rivers and the downstream marine environment, supporting aquatic life and recreational uses.

The plant's treated effluent flows into the Aniene River, a tributary of the Tiber River, which then discharges into the Tyrrhenian Sea near Rome. This watershed supports diverse aquatic ecosystems and is important for regional water resources. The advanced treatment helps reduce nutrient loading, which is critical for preventing eutrophication in the coastal marine environment.
