IMPIANTO C DA S MICHELE Wastewater Treatment Plant, Gioiosa Marea, Sicily

IMPIANTO C DA S MICHELE is a municipal wastewater treatment plant located in the Contrada Catello area of Gioiosa Marea, a coastal town in the province of Messina, Sicily, Italy. The plant serves a population of approximately 4,465 residents and has a designed capacity of 10,000 cubic meters per day, indicating it is sized to accommodate seasonal population fluctuations common in Mediterranean tourist areas. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000 discharging into coastal waters. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with EU effluent quality standards before discharge. The treated effluent is discharged into the local environment within 10 kilometers of the Tyrrhenian Sea coast. The receiving waters ultimately flow into the Tyrrhenian Sea, part of the Mediterranean Sea basin. The plant plays a key role in protecting the coastal marine ecosystem from untreated sewage, supporting bathing water quality and marine biodiversity along the northern Sicilian coast.

The plant discharges into the Tyrrhenian Sea, a basin of the Mediterranean Sea, via local coastal waters. The area supports diverse marine life, including seagrass meadows and fish nursery habitats, which are sensitive to nutrient pollution. Secondary treatment helps reduce the risk of eutrophication and maintains water quality for tourism and fishing along the Sicilian coast.
