Impianto Boschetto Vaccheria Wastewater Treatment Plant, Maniace, Sicily

Impianto Boschetto Vaccheria is a municipal wastewater treatment plant located in Maniace, a town in the province of Catania, Sicily, Italy. The plant serves a population of approximately 2,482 residents and is part of the region's wastewater infrastructure for inland communities. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,300 m³/day and an average discharge volume of 491.35 m³/day, the facility operates well within its capacity, ensuring effective treatment of domestic wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Ionian Sea via the Simeto River basin. The plant plays a key role in protecting the water quality of the Simeto River and its downstream ecosystems, including coastal areas that support diverse marine life and are important for local fisheries and tourism.

The plant discharges into the Simeto River basin, which flows into the Ionian Sea near Catania. The Simeto is the largest river in Sicily and supports a variety of aquatic habitats, including riparian zones and wetlands that are important for migratory birds and endemic fish species. Downstream, the coastal waters are ecologically sensitive, hosting seagrass meadows and marine biodiversity that benefit from reduced nutrient pollution from well-treated wastewater.
