PRATA DI PRINCIPATO ULTRA Depuratore di Prata e Pratola - Secondary Wastewater Treatment Plant in Campania, Italy

PRATA_DI_PRINCIPATO_ULTRA DEPURATORE DI PRATA E PRATOLA is a municipal wastewater treatment plant located in Prata di Principato Ultra, in the province of Avellino, Campania, Italy. The plant serves a population of 3,600 and has a designed capacity of 7,000 cubic meters per day, with an average discharge volume of 712.67 cubic meters per day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000 in normal areas, and more stringent treatment in sensitive zones. The plant's capacity utilization appears moderate, indicating operational headroom. The treated effluent is discharged into the local water system, which ultimately drains into the Tyrrhenian Sea via the Sabato River and the Gulf of Salerno. The plant plays a key role in protecting the water quality of the Sabato River and downstream coastal environments, supporting both ecological health and recreational uses.

The plant discharges into the Sabato River, a tributary of the Calore Irpino River, which flows into the Volturno River and eventually reaches the Tyrrhenian Sea near the Gulf of Gaeta. This watershed supports diverse aquatic life and is important for regional agriculture and tourism. The secondary treatment helps reduce organic pollutants and protect downstream ecosystems, including coastal waters that are ecologically sensitive.
