SALGAREDA VIA CALLURBANA Wastewater Treatment Plant, Campobernardo, Veneto

SALGAREDA VIA CALLURBANA is a municipal wastewater treatment plant located in Campobernardo, a locality in the municipality of Salgareda, in the Veneto region of northeastern Italy. The plant serves a small population of 240 people, reflecting the rural character of the area. It is situated near the Piave River basin, which flows into the Adriatic Sea. 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 designed capacity is 250 m³/day, and the current discharge volume is 47.51 m³/day, indicating ample capacity headroom. As a small-scale facility, it is subject to national regulations implemented by the Italian Ministry of Environment and local water authorities. The treated effluent is discharged into a local watercourse that ultimately drains into the Adriatic Sea via the Piave River or its tributaries. The plant's proximity to the coast (within 10 km) means that its discharge contributes to the nutrient load in the coastal zone, which is ecologically sensitive due to the presence of seagrass meadows and marine biodiversity in the northern Adriatic.

The plant discharges into a tributary of the Piave River, which flows into the Adriatic Sea near the Venetian Lagoon. The northern Adriatic is a shallow, semi-enclosed sea with limited water exchange, making it vulnerable to nutrient enrichment from wastewater discharges. The area supports important fisheries and migratory bird populations, and the coastal waters are designated as sensitive under the EU Urban Waste Water Treatment Directive, requiring advanced treatment for larger plants. The small population served by this plant means its nutrient contribution is relatively minor, but cumulative impacts from multiple small discharges in the region are a concern.
