SUMMONTE IMP DI SUMMONTE LOCALITA STARZE Wastewater Treatment Plant, San Mango sul Calore

SUMMONTE IMP DI SUMMONTE LOCALITA STARZE is a municipal wastewater treatment plant located in the Lario area of San Mango sul Calore, in the province of Avellino, Campania, Italy. The plant serves a small population of 850 residents, reflecting its role in a rural or small-town setting within the Calore River valley. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. Although the plant serves fewer than 2,000 people, it still meets secondary treatment standards, ensuring effective removal of organic matter and suspended solids. The designed capacity is 1,000 cubic meters per day, and the current discharge volume is 168.27 cubic meters per day, indicating ample reserve capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Calore River, a tributary of the Volturno River, which flows into the Tyrrhenian Sea. The plant's operation helps protect the Calore River basin from untreated sewage, supporting aquatic life and downstream water quality in this ecologically sensitive region of southern Italy.

The plant discharges into the Calore River basin, which flows into the Volturno River and then into the Tyrrhenian Sea. The Calore River supports diverse aquatic ecosystems and is an important water resource for agriculture and biodiversity in Campania. Secondary treatment reduces organic pollution, protecting downstream habitats and the coastal marine environment from nutrient enrichment.
