Overview
Contrada Naca is a secondary wastewater treatment plant in Ispica, Sicily, serving about 17,780 people. It discharges treated effluent near the coast, operating under Italy's implementation of the EU Urban Waste Water Treatment Directive.
Contrada Naca is a wastewater treatment plant located in Ispica, a town in the province of Ragusa, Sicily, Italy. The facility serves a population of approximately 17,780, classifying it as a medium agglomeration under EU regulations. Its coastal location places it within 10 kilometers of the Mediterranean Sea, making it subject to stringent discharge requirements. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland and coastal discharges from agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The designed capacity of 17,780 cubic meters per day matches the population served, indicating adequate sizing. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The coastal waters near Ispica support diverse marine life and are part of the broader Ionian Sea ecosystem. The plant's operation helps protect these waters from nutrient pollution and pathogens, contributing to the ecological health of the region.
Environmental context
The plant discharges into the Ionian Sea via local watercourses, affecting a coastal zone that supports seagrass meadows and fish nurseries. The Mediterranean Sea in this area is sensitive to nutrient inputs, and secondary treatment reduces the risk of eutrophication. The plant's proximity to the coast (within 10 km) means its effluent can quickly reach marine habitats, emphasizing the need for effective treatment.
Frequently asked questions
Contrada Naca is located in Ispica, a town in the province of Ragusa, Sicily, Italy. The plant serves the local municipality and surrounding areas.
The plant serves approximately 17,780 people, classifying it as a medium-sized agglomeration under EU wastewater treatment regulations.
The plant discharges treated effluent into local watercourses that flow into the Mediterranean Sea. Its coastal location (within 10 km of the coast) means the effluent reaches marine waters relatively quickly.
Contrada Naca provides secondary treatment, which involves biological processes to reduce organic matter and suspended solids. This meets the EU Urban Waste Water Treatment Directive requirements for discharges into coastal waters from agglomerations of this size.
The plant operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). For a medium agglomeration (10,000-100,000 population equivalent) discharging to coastal waters, secondary treatment is mandatory. Italy's environmental authorities oversee compliance through permits and monitoring.
