Sala Consilina Impianto Loc Macchia Dell'Aspide - Secondary Wastewater Treatment Plant in Campania, Italy

The Sala Consilina Impianto Loc Macchia Dell'Aspide is a municipal wastewater treatment facility located in Sala Consilina, a town in the Campania region of southern Italy. The plant serves a population of approximately 3,800 residents, reflecting its role in managing domestic wastewater for a small community in the Vallo di Diano 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. With a designed capacity of 5,000 m³/day and an actual discharge volume of 752.27 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain 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 discharge contributes to the freshwater quality of the region's rivers, which support diverse aquatic life and agricultural activities in the surrounding area.

The plant discharges into the local drainage network that flows into the Sele River, a major watercourse in Campania that empties into the Tyrrhenian Sea. The Sele River basin supports diverse aquatic ecosystems and is important for regional agriculture and biodiversity. The plant's secondary treatment helps protect downstream water quality, reducing nutrient loads that could otherwise contribute to eutrophication in coastal waters.
