OPPEANO_CASOTTON Wastewater Treatment Plant, Isola Rizza, Veneto, Italy

OPPEANO_CASOTTON is a wastewater treatment plant located in Isola Rizza, a municipality in the province of Verona, Veneto, Italy. Serving a population equivalent of 5,060, the plant is part of the region's municipal wastewater infrastructure, which is managed under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). As a small agglomeration (under 10,000 population equivalent), the plant is required to provide appropriate treatment to meet EU standards. Italian plants of this scale typically employ secondary biological treatment to comply with national regulations. The plant's design capacity and operational status are consistent with standard practices for small-to-medium communities in the Veneto region. The plant's treated effluent is discharged into local waterways that drain into the Po River basin, the largest river system in Italy. The Po River flows eastward into the Adriatic Sea, supporting extensive agricultural activity and diverse aquatic ecosystems. The plant plays a role in protecting downstream water quality in this ecologically and economically significant basin.

The plant discharges into the Po River basin, which ultimately drains into the Adriatic Sea. This watershed supports intensive agriculture and is home to numerous fish species, including the European eel and sturgeon. The Po Delta is a critical habitat for migratory birds and aquatic life, making effective wastewater treatment essential for maintaining water quality and ecological balance in the region.
