BUJA_AVILLA Wastewater Treatment Plant, Tomba/Tombe, Buja, Friuli-Venezia Giulia, Italy

BUJA_AVILLA is a small wastewater treatment plant located in the municipality of Buja, in the Friuli-Venezia Giulia region of northeastern Italy. The plant serves a population of 352 residents in the locality of Tomba/Tombe, near the Alpe-Adria motorway. As a small-scale facility, it is part of Italy's decentralized wastewater infrastructure for rural communities. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) below 2,000 are subject to appropriate treatment requirements, typically secondary treatment or equivalent. Italy implements this directive through national legislation, and small plants like BUJA_AVILLA are expected to meet these standards to protect receiving water bodies. The plant's treated effluent likely discharges into local streams that flow into the Tagliamento River, one of the last morphologically intact rivers in the Alps, which drains into the Adriatic Sea near Lignano Sabbiadoro. The Tagliamento supports diverse aquatic habitats and is an important corridor for migratory fish species. Proper treatment at BUJA_AVILLA helps maintain water quality in this ecologically significant river system.

BUJA_AVILLA discharges into the Tagliamento River basin, which flows through Friuli-Venezia Giulia into the northern Adriatic Sea. The Tagliamento is known for its braided gravel-bed channels and supports a rich diversity of aquatic life, including rare fish and invertebrate species. The downstream environment includes coastal lagoons and the Gulf of Venice, which are sensitive to nutrient inputs. Effective wastewater treatment at this plant helps protect the ecological integrity of the Tagliamento and the Adriatic coastal zone.
