Due Carrare Via Cuccara Loc Terradura Wastewater Treatment Plant, Terradura, Veneto

The Due Carrare Via Cuccara Loc Terradura wastewater treatment plant is located in Terradura, a locality within the municipality of Due Carrare in the Veneto region of northern Italy. The plant serves a population of approximately 1,686 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). It is situated inland, more than 10 km from the coast but within 50 km of the Adriatic Sea. As a secondary treatment facility, the plant provides biological treatment to remove organic matter and suspended solids, meeting the minimum requirements for inland discharges under the EU UWWTD. The plant has a designed capacity of 1,700 m³/day and currently discharges an average volume of 333.77 m³/day, indicating operational capacity well below design limits. The plant operates under Italy's national implementation of the EU UWWTD, which mandates secondary treatment for agglomerations of this size. The treated effluent is discharged into local watercourses that drain into the Adriatic Sea via the Po River basin or nearby coastal systems. The Veneto region features a dense network of rivers and canals that support agricultural irrigation and sensitive aquatic habitats. Proper treatment at this plant helps protect downstream water quality in the Po Delta and the northern Adriatic, an area known for its ecological significance and tourism value.

The plant discharges into local waterways that ultimately flow into the Adriatic Sea, likely via the Bacchiglione or Brenta river systems. The Veneto lowlands are characterized by intensive agriculture and urban development, making nutrient removal critical to prevent eutrophication in the Po Delta and coastal lagoons. The northern Adriatic is a shallow, semi-enclosed sea with limited water exchange, making it sensitive to nutrient inputs that can cause algal blooms and hypoxia.
