Sandrigo Viale della Repubblica Wastewater Treatment Plant, Sandrigo, Veneto

Sandrigo Viale della Repubblica is a municipal wastewater treatment plant located in Sandrigo, a town in the province of Vicenza, Veneto, Italy. The plant serves a population of 797 and has a designed capacity of 1000 cubic meters per day, with an actual discharge volume of 157.78 cubic meters per day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. For smaller agglomerations like Sandrigo (under 2,000 PE), the directive requires appropriate treatment, and secondary treatment exceeds this minimum, ensuring effective removal of organic matter and suspended solids. The treated effluent is discharged into local watercourses that drain into the Bacchiglione River, which flows through the Veneto region and eventually into the Adriatic Sea near Chioggia. This discharge supports the ecological health of the downstream aquatic environment, including the sensitive lagoon ecosystems of the Venetian coast.

The plant discharges into the Bacchiglione River basin, which flows through the Veneto plain and into the Adriatic Sea. The downstream environment includes ecologically sensitive coastal lagoons and wetlands that support diverse aquatic life and migratory bird species. Proper treatment is essential to prevent nutrient enrichment and protect these habitats.
