DP01705002_CETO_CAMPAGNELLI Wastewater Treatment Plant, Nadro, Lombardy

DP01705002_CETO_CAMPAGNELLI is an advanced wastewater treatment plant located in Nadro, a frazione of Ceto in the Val Camonica, Lombardy, Italy. The plant serves a small population of 77 residents and is designed with a capacity of 300 m³/day, with a current discharge volume of 15.24 m³/day. It is situated inland, far from the coast, and treats wastewater from the local community. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. This level of treatment is typical for plants discharging into sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for agglomerations above 10,000 PE in sensitive zones. Although the plant serves a smaller population, its advanced status reflects local environmental requirements. The plant's effluent is discharged into the Oglio River, which flows through the Camonica Valley and eventually joins the Po River, the longest river in Italy. The Po River drains into the Adriatic Sea, making the plant's treatment important for protecting downstream water quality and the ecological health of the Po basin.

The plant discharges into the Oglio River, a tributary of the Po River, which flows into the Adriatic Sea. The Oglio River supports diverse aquatic life and is part of a region known for its ecological sensitivity, including areas designated for their natural heritage. The advanced treatment helps protect the river's water quality and the downstream Po Delta ecosystem.
