IMPIANTO_CDA_STINCO Wastewater Treatment Plant, San Marco d'Alunzio, Sicily

IMPIANTO_CDA_STINCO is a municipal wastewater treatment plant located in San Marco d'Alunzio, a town in the province of Messina, Sicily, Italy. The plant serves a population of approximately 2,800 residents and operates with secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. As a secondary treatment facility, the plant uses biological processes to remove organic matter and suspended solids from wastewater. The plant has a designed capacity of 2,800 cubic meters per day and currently discharges about 554.30 cubic meters per day, indicating it operates well below its capacity. The plant's proximity to the coast (within 10 km) means its treated effluent may eventually reach the Tyrrhenian Sea, a part of the Mediterranean Sea. Given its coastal location, the treated wastewater likely flows into a nearby stream or directly into the sea. The plant plays a key role in protecting the local marine environment from untreated sewage, supporting the ecological health of the coastal waters and the broader Mediterranean ecosystem.

The plant is situated in the coastal region of northeastern Sicily, near the Tyrrhenian Sea. The local watershed includes small streams that drain the Nebrodi Mountains and flow into the sea. The treated effluent from the plant likely enters a watercourse that eventually reaches the Tyrrhenian Sea, which is part of the Mediterranean Sea. This coastal area supports diverse marine life, including seagrass meadows and fish populations, and is an important migratory corridor for sea turtles and cetaceans. Proper wastewater treatment is essential to prevent nutrient pollution and protect these sensitive habitats.
