ACCETTURA_CDA_LAGO Wastewater Treatment Plant, Accettura, Basilicata

ACCETTURA_CDA_LAGO is a municipal wastewater treatment plant located in Accettura, a town in the Basilicata region of southern Italy. The plant serves a population of approximately 2,440 residents and is situated along the Strada Provinciale Accettura-Gallipoli. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant has a designed capacity of 3,000 m³/day and currently treats an average daily flow of 483 m³/day, indicating significant reserve capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 2,000 and 10,000 are required to have secondary treatment, which this plant meets. The facility operates under Italian national regulations that transpose the directive, ensuring compliance with effluent standards. The treated effluent is discharged into a local watercourse that eventually drains into the Ionian Sea via the Basento River basin. The region's watershed supports diverse aquatic life and is part of the broader Mediterranean ecosystem. Proper treatment at this plant helps protect downstream water quality and ecological health in the Basilicata region.

The plant discharges into a local stream that flows into the Basento River, which empties into the Gulf of Taranto in the Ionian Sea. This watershed supports a variety of freshwater species and is important for regional biodiversity. The secondary treatment process reduces nutrient loads, helping to prevent eutrophication in downstream waters and maintaining the ecological balance of the coastal marine environment.
