CALTO_S_P_ERIDANIA Wastewater Treatment Plant, Calto, Veneto, Italy

CALTO_S_P_ERIDANIA is an advanced wastewater treatment plant located in Calto, a municipality in the province of Rovigo, Veneto, Italy. The plant serves a population of 766 and is part of the region's municipal wastewater infrastructure, operating under Italian and European Union regulations. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,300 m³/day and a current discharge volume of 151.64 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. As an advanced treatment plant, it meets the stringent requirements of the EU Urban Waste Water Treatment Directive for sensitive areas. The treated effluent is discharged into local water bodies that ultimately drain into the Po River basin, one of Italy's most important watersheds. The Po River flows into the Adriatic Sea, supporting diverse aquatic ecosystems and agricultural activities. The plant's advanced treatment helps protect downstream water quality and the ecological health of the Po Delta region.

The plant discharges into the Po River basin, which flows through northern Italy and empties into the Adriatic Sea. The Po Delta is an ecologically sensitive area that supports diverse aquatic life, including fish and bird species, and is an important migratory corridor. Advanced treatment at this plant helps reduce nutrient loading, protecting the delta's fragile ecosystem from eutrophication.
