IMPIANTO C DA SIRIERI is a wastewater treatment plant located in Enna, in the Sicilia region of Italy. It serves a population equivalent of 26,290, classifying it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, approximately 50 km from the coast, and its operations are part of the regional wastewater infrastructure managed by local authorities. Under the EU UWWTD, agglomerations of this scale (between 10,000 and 100,000 population equivalent) are required to provide secondary treatment as a minimum standard. The plant is expected to comply with Italian national regulations that transpose the directive. The designed capacity is listed as 1.00, though the unit is unspecified; this likely refers to a flow or load parameter relevant to the plant's design. The treated effluent from the plant discharges into the local watershed, which ultimately drains into the Mediterranean Sea via the southern Sicilian river systems. The region's semi-arid climate and karst geology make water resources particularly sensitive, and proper wastewater treatment is essential to protect both groundwater and coastal ecosystems. The plant plays a key role in maintaining water quality in the area, supporting agricultural and ecological needs downstream.
Environmental context
The plant discharges into the local watershed of central Sicily, which drains through ephemeral streams and rivers toward the Mediterranean Sea. The receiving environment includes the Gulf of Gela, a coastal area that supports diverse marine life and is important for local fisheries. The region's karst topography means groundwater is vulnerable to contamination, making effective wastewater treatment critical for protecting both surface and subsurface water resources.
Frequently asked questions
IMPIANTO C DA SIRIERI is located in Enna, in the Sicilia region of Italy. The full address is Enna, Sicilia, 94100, Italia.
The plant serves a population equivalent of 26,290, which classifies it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive.
The treated effluent from the plant discharges into the local watershed of central Sicily, which ultimately drains into the Mediterranean Sea via rivers and streams in the region.
As an Italian plant serving over 10,000 population equivalent, IMPIANTO C DA SIRIERI operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum for agglomerations of this size.
Under the EU UWWTD, plants serving between 10,000 and 100,000 population equivalent must provide at least secondary treatment. In sensitive areas, such as those draining into the Mediterranean, tertiary treatment may be required to reduce nutrient loads.
