Piaggine Impianto di Depurazione di Piaggine - Secondary Wastewater Treatment in Valle dell'Angelo, Campania

Piaggine Impianto di Depurazione di Piaggine is a municipal wastewater treatment plant located in Valle dell'Angelo, in the province of Salerno, Campania, Italy. The facility serves a population of approximately 2,330 residents and is part of the regional wastewater infrastructure managed under Italian and European regulations. The plant provides secondary treatment, which is the standard level required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,500 cubic meters per day, the plant handles an average daily flow of about 461 cubic meters, indicating significant reserve capacity 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 plays a key role in protecting the water quality of the region's rivers and coastal environment, supporting both ecological health and recreational uses downstream.

The plant discharges into the Sele River basin, which flows into the Tyrrhenian Sea near the Gulf of Salerno. This coastal area supports diverse marine life and is important for local fisheries and tourism. The secondary treatment process reduces organic pollutants and suspended solids, helping to maintain water quality in the river and coastal zone, which is ecologically sensitive due to its proximity to the Cilento and Vallo di Diano National Park.
