Montemiletto Impianto di Montemiletto Wastewater Treatment Plant, Campania

The Montemiletto Impianto di Montemiletto wastewater treatment plant serves the municipality of Montemiletto in the Campania region of southern Italy. Located in the province of Avellino, the facility provides secondary treatment for a population equivalent of 2,600 residents, reflecting its role in managing domestic wastewater for this inland community. As a secondary treatment plant, it meets the minimum standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. The plant's designed capacity of 2,600 cubic meters per day aligns with the population served, indicating adequate infrastructure for current demand. The treated effluent is discharged into local watercourses that drain into the Calore Irpino River, a tributary of the Volturno River, which ultimately flows into the Tyrrhenian Sea. The plant's operation helps protect the water quality of these rivers and the downstream coastal environment.

The plant discharges into the Calore Irpino River basin, which feeds into the Volturno River, one of southern Italy's major river systems. The Volturno flows into the Tyrrhenian Sea near the Gulf of Gaeta. The watershed supports diverse aquatic life and is used for irrigation and recreation. Secondary treatment reduces organic pollutants and suspended solids, mitigating eutrophication risks in downstream waters.
