Overview
Impianto C da Lettiera is a wastewater treatment plant serving Pachino, Sicily, Italy. It serves a population of 10,000 and is located within 50 km of the coast, discharging into the Mediterranean Sea basin.
Impianto C da Lettiera is a wastewater treatment plant located in Pachino, a town in the province of Siracusa on the island of Sicily, Italy. The plant serves a population of approximately 10,000 people, placing it in the small to medium agglomeration category under Italian and EU regulations. Its location near the southern coast of Sicily places it within the Mediterranean coastal zone. As a plant serving a population of 10,000, it falls under the scope of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuaries, and more stringent treatment for discharges into sensitive areas. The plant is expected to meet these regulatory standards. The designed capacity of 1.00 (likely in thousands of cubic meters per day) suggests it is sized appropriately for its service population. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The receiving environment includes coastal waters that support diverse marine life and are important for local fisheries and tourism. Proper treatment is essential to protect water quality in this ecologically sensitive coastal area.
Environmental context
The plant discharges into the Mediterranean Sea via local watercourses near Pachino. The coastal waters of southeastern Sicily support seagrass meadows and diverse marine fauna, including species of conservation interest. The area is also important for tourism and agriculture, making nutrient and pathogen removal critical to prevent eutrophication and protect public health.
