Costa di Rovigo Via Dossei Wastewater Treatment Plant - Veneto, Italy

Costa di Rovigo Via Dossei is a wastewater treatment plant located in Costa di Rovigo, in the Veneto region of northern Italy. The plant serves a small population of 1,757 residents, reflecting its role in a rural or small-town setting. It is situated inland, away from coastal areas, and operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU directive for agglomerations of this size. With a design capacity of 2,000 m³/day and a current discharge volume of 347.82 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The advanced treatment level suggests the plant is equipped to remove nutrients such as nitrogen and phosphorus, which is typical for plants discharging into sensitive areas. The treated effluent is discharged into local watercourses that eventually drain into the Po River basin, one of Italy's most important hydrological systems. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic life and agricultural activities. The plant's advanced treatment helps protect downstream water quality in this ecologically and economically vital region.

The plant discharges into the Po River basin, which drains into the Adriatic Sea. The Po River is Italy's longest river and supports a rich ecosystem, including migratory fish species and extensive wetlands in its delta. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in the Adriatic, which is a semi-enclosed sea sensitive to algal blooms.
