POZZONOVO_VIA_VALLASE Wastewater Treatment Plant, Stroppare, Veneto

POZZONOVO_VIA_VALLASE is an advanced wastewater treatment plant located in Stroppare, a locality within the municipality of Pozzonovo, in the province of Padova, Veneto, Italy. The plant serves a population equivalent of 3,596, placing it in the small agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. With a designed capacity of 14,700 m³/day and a reported discharge volume of 711.88 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into the local water network, which ultimately drains into the Adriatic Sea via the Po River basin. The plant's location within 50 km of the coast means its discharge contributes to the nutrient load entering the Adriatic, a semi-enclosed sea sensitive to eutrophication. Advanced treatment helps reduce this impact.

The plant discharges into the Po River basin, which flows eastward through northern Italy and empties into the Adriatic Sea. The Adriatic is a semi-enclosed sea with limited water exchange, making it vulnerable to nutrient enrichment from agricultural and urban runoff. Advanced treatment at this plant helps reduce the load of nitrogen and phosphorus, supporting the ecological health of the Po delta and coastal waters, which host diverse marine life and important fisheries.
