Caselle in Pittari Depuratore Comunale - Secondary Wastewater Treatment Plant, Campania, Italy

Caselle in Pittari Depuratore Comunale is a municipal wastewater treatment plant located in Caselle in Pittari, a town in the province of Salerno, Campania, Italy. The plant serves a population of approximately 1,500 people, classifying it as a small agglomeration under Italian and EU regulations. The facility provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The plant has a designed capacity of 1,500 cubic meters per day and reports a discharge volume of about 297 cubic meters per day, indicating operational headroom. The treated effluent is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea. The coastal location (within 10 km of the coast) means the plant's discharge contributes to the nutrient and pollutant load in a sensitive marine environment, where eutrophication risks are a concern.

The plant discharges into the Bussento River basin, which flows into the Tyrrhenian Sea near the Gulf of Policastro. This coastal area supports diverse marine life and is part of a region with important seagrass meadows and fish nursery habitats. The proximity to the coast increases the potential impact of nutrient discharges on marine water quality.
