ARTEGNA_LOC_PALUT Wastewater Treatment Plant, Artegna, Friuli-Venezia Giulia

ARTEGNA_LOC_PALUT is a wastewater treatment plant located in the municipality of Artegna (Dartigne) in the Friuli-Venezia Giulia region of northeastern Italy. The plant serves a small population of 933 residents, reflecting its role in a rural or small-town setting. Its location in the foothills of the Julian Alps places it within a region known for its rivers and proximity to the Adriatic coast. 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 with a population equivalent (PE) between 2,000 and 10,000. Secondary treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids. The designed capacity of 4,500 cubic meters per day suggests the plant can handle peak flows or future growth, with current discharge volume at 479.64 cubic meters per day. The treated effluent is discharged into the local water system, which flows into the Tagliamento River basin, one of the last morphologically intact river systems in the Alps. The Tagliamento River eventually reaches the Adriatic Sea near the Gulf of Venice. This watershed supports diverse aquatic habitats and is an important ecological corridor. The plant's operation helps protect downstream water quality in a region valued for its natural landscapes and tourism.

The plant discharges into the Tagliamento River basin, which flows through Friuli-Venezia Giulia and into the Adriatic Sea. The Tagliamento is known for its braided channels and gravel bars, supporting a unique riparian ecosystem with diverse fish and bird species. Downstream, the river delta and coastal lagoons are ecologically sensitive areas that benefit from controlled nutrient and pollutant loads. The plant's secondary treatment helps reduce organic pollution, safeguarding water quality in this dynamic alpine-to-coastal system.
