Trevenzuolo Loc Fagnano Wastewater Treatment Plant | Veneto, Italy

Trevenzuolo Loc Fagnano is an advanced wastewater treatment plant located in the Fagnano hamlet of Trevenzuolo, in the Veneto region of northern Italy. The plant serves a population of 1,075 and has a designed capacity of 1,500 m³/day, with a current discharge volume of 212.81 m³/day. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for small agglomerations. The plant provides advanced treatment, which includes nutrient removal beyond secondary standards. This level of treatment is typical for plants discharging into sensitive areas or upstream of water bodies requiring high effluent quality. The plant's capacity utilization is low, indicating ample headroom for future growth or seasonal variations. The treated effluent is discharged into local watercourses that drain into the Adige River basin, eventually reaching the Adriatic Sea. The plant plays a key role in protecting the regional water quality, particularly in an area known for agriculture and viticulture, where nutrient pollution is a concern.

The plant discharges into the Adige River basin, which flows through the Veneto plain into the Adriatic Sea. The downstream environment includes agricultural areas and the Po Delta, a region of high ecological value supporting diverse aquatic life and migratory birds. Advanced treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the Adriatic.
