TRIVIGNO_CDA_VALLE Wastewater Treatment Plant, Trivigno, Basilicata

TRIVIGNO_CDA_VALLE is a municipal wastewater treatment plant located in Trivigno, a town in the province of Potenza, Basilicata, Italy. The plant serves a small population of approximately 1,000 residents, reflecting its role in managing domestic wastewater for this rural community. The facility operates with secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. Although the plant's population served is below this threshold, secondary treatment ensures effective removal of organic matter and suspended solids. The plant has a designed capacity of 1,000 cubic meters per day and reports a discharge volume of about 198 cubic meters per day. The treated effluent is discharged into local water bodies that drain into the Basilicata watershed, ultimately contributing to the Ionian Sea via rivers such as the Basento or Bradano. The plant's operation helps protect downstream aquatic ecosystems and supports water quality in a region known for its agricultural and natural landscapes.

The plant discharges into small streams within the Basilicata region, which flow into larger rivers like the Basento or Bradano before reaching the Gulf of Taranto in the Ionian Sea. This watershed supports diverse aquatic life and is important for regional agriculture and biodiversity. The secondary treatment provided helps reduce nutrient and organic pollution, mitigating eutrophication risks in downstream coastal waters.
