ANZI_CDA_RAIA Wastewater Treatment Plant, Anzi, Basilicata, Italy

ANZI_CDA_RAIA is a municipal wastewater treatment plant located in Anzi, a town in the Basilicata region of southern Italy. The plant serves a population of approximately 1,559 residents, reflecting its role in managing domestic wastewater for a small community in the Apennine foothills. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 1,600 cubic meters per day and a discharge volume of about 309 cubic meters per day, the facility operates well within its capacity, ensuring effective treatment of the local wastewater load. The treated effluent is discharged into the local watershed, which ultimately drains toward the Ionian Sea via the Basento River or nearby streams. This discharge supports the ecological health of the receiving water bodies, contributing to the protection of aquatic life and downstream water quality in the Basilicata region.

The plant's discharge enters the local drainage network, which flows into the Basento River, a major watercourse in Basilicata that empties into the Gulf of Taranto in the Ionian Sea. The Basento River supports diverse aquatic ecosystems and is important for regional biodiversity, including fish populations and riparian habitats. Proper treatment at ANZI_CDA_RAIA helps reduce nutrient and pollutant loads, safeguarding water quality in this sensitive Mediterranean coastal zone.
