Impianto C da Giarruso Ulmi Guzza Wastewater Treatment Plant, Vizzini, Sicily

Impianto C da Giarruso Ulmi Guzza is a wastewater treatment plant located in Vizzini, in the province of Catania, Sicily, Italy. The plant serves a population of approximately 9,449 residents, placing it in the small-to-medium agglomeration category under Italian and EU regulations. As a plant in Italy, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size discharging into fresh water or estuaries. The plant's treated effluent likely discharges into local watercourses that drain into the Mediterranean Sea. Sicily's water resources are ecologically sensitive due to the island's Mediterranean climate and seasonal water scarcity. The plant plays a role in protecting downstream aquatic habitats and coastal water quality.

The plant is located inland in Sicily, over 50 km from the coast. Its treated wastewater likely flows into local streams or rivers that eventually reach the Mediterranean Sea. The region's water bodies support diverse aquatic life and are important for irrigation and local ecosystems. Protecting these waters from nutrient pollution is critical given the island's limited freshwater resources and tourism-dependent coastal areas.
