S_ANGELO_DEI_LOMBARDI_IMPIANTO_LOCALITA_PETRARA Wastewater Treatment Plant, Sant'Angelo dei Lombardi, Italy

S_ANGELO_DEI_LOMBARDI_IMPIANTO_LOCALITA_PETRARA is a wastewater treatment plant located in Sant'Angelo dei Lombardi, a town in the province of Avellino, Campania, Italy. The plant serves a population of approximately 1,000 people and is part of the municipal wastewater infrastructure for the area. 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. The directive mandates secondary treatment for all discharges from agglomerations with a population equivalent (PE) between 2,000 and 10,000, and the plant's capacity of 1,000 m³/day aligns with this scale. The treated effluent is discharged into local watercourses that drain into the Ofanto River basin, eventually reaching the Adriatic Sea. The plant plays a key role in protecting the local watershed and downstream ecosystems from untreated sewage, supporting water quality in the region.

The plant discharges into the Ofanto River basin, which flows into the Gulf of Manfredonia in the Adriatic Sea. The Ofanto River supports diverse aquatic life and is an important migratory corridor for fish species. The secondary treatment provided helps reduce organic load and nutrient pollution, protecting the river's ecological health and the coastal waters of the Adriatic.
