ROTELLO_DIFESA_NUOVA Wastewater Treatment Plant, Rotello, Molise, Italy

ROTELLO_DIFESA_NUOVA is an advanced wastewater treatment plant located in Rotello, in the Molise region of Italy. The plant serves a population of approximately 1,666 people, making it a small-scale facility within the local municipal infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,710 m³/day and a discharge volume of 329.81 m³/day, the plant operates well within its capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this are required to provide appropriate treatment, and the advanced level here exceeds the minimum secondary treatment standard. The treated effluent is discharged into the local watershed, which ultimately drains into the Adriatic Sea. The plant plays a key role in protecting the region's water quality, particularly given its proximity to the coast (within 50 km), supporting both local ecosystems and downstream marine environments.

The plant discharges into the local drainage basin of the Molise region, which flows into the Adriatic Sea. The receiving water bodies support diverse aquatic life and are important for regional biodiversity. The advanced treatment helps minimize nutrient loading, protecting coastal waters from eutrophication and maintaining the ecological health of the Adriatic Sea.
