Overview
Sant'Arsenio Impianto Localita Difesa is a secondary wastewater treatment plant serving 600 people in Sant'Arsenio, Campania, Italy. It discharges 118.78 m³/day of treated effluent into the local watershed.
Sant'Arsenio Impianto Localita Difesa is a municipal wastewater treatment plant located in Sant'Arsenio, a town in the province of Salerno, Campania, Italy. The plant serves a small population of 600 residents, reflecting its role in a rural or small-town 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. With a designed capacity of 900 m³/day and an actual discharge volume of 118.78 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated wastewater is discharged into the local water system, which ultimately drains into the Tyrrhenian Sea via the Sele River basin. The plant's location inland, more than 10 km from the coast, reduces direct marine impact, but its effluent contributes to the freshwater ecosystem of the Campania region, supporting local streams and agricultural water use.
Environmental context
The plant discharges into the inland watershed of the Sele River basin, which flows into the Tyrrhenian Sea. This basin supports diverse aquatic life and is used for irrigation in the surrounding agricultural areas. The secondary treatment level helps reduce organic pollutants, protecting downstream water quality in a region known for its sensitive karst aquifers and coastal ecosystems.
