San Leucio del Sannio Impianto Frazione Maccabei - Secondary Wastewater Treatment Plant in Campania, Italy

San Leucio del Sannio Impianto Frazione Maccabei is a municipal wastewater treatment plant located in the Maccabei area of San Leucio del Sannio, in the province of Benevento, Campania, Italy. The plant serves a small population of approximately 300 residents, reflecting its role in a rural or suburban setting within the Campania region. 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 of this size. Secondary treatment effectively removes organic matter and suspended solids, ensuring the effluent meets quality standards before discharge. The plant has a designed capacity of 300 cubic meters per day and currently treats an average daily volume of about 59 cubic meters, indicating ample capacity for current loads. The treated wastewater is discharged into local water bodies that eventually drain into the Tyrrhenian Sea via the Volturno River or other regional basins. This discharge supports the ecological balance of local streams and rivers, which are part of the broader Mediterranean watershed. The plant's operation helps protect downstream water quality and aquatic habitats in the Campania region.

The plant discharges into local watercourses that flow into the Volturno River basin, which ultimately reaches the Tyrrhenian Sea. This watershed supports diverse aquatic life and is important for regional agriculture and tourism. The secondary treatment process reduces organic pollutants and nutrients, helping to prevent eutrophication in downstream water bodies and maintaining the ecological health of the Mediterranean coastal zone.
