Overview
GORIZIA wastewater treatment plant serves Gorizia, Friuli-Venezia Giulia, Italy, with a population equivalent of 33,045. It operates under the EU Urban Waste Water Treatment Directive.
The GORIZIA wastewater treatment plant is located in Gorizia, in the Friuli-Venezia Giulia region of northeastern Italy, near the border with Slovenia. The plant serves a population of approximately 33,045 people, classifying it as a medium-sized agglomeration under EU regulations. As a plant in an EU member state, GORIZIA is subject to the Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuaries for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar units), indicating its scale. The treated effluent from the plant is discharged into the local water system, which ultimately drains into the Adriatic Sea via the Isonzo River (Soča). The Isonzo River basin supports diverse aquatic life and is an important ecological corridor in the region. The plant's operation helps protect the water quality of the river and the northern Adriatic coastal environment.
Environmental context
The GORIZIA plant discharges into the Isonzo River (Soča) basin, which flows southward through Slovenia and Italy before entering the Gulf of Trieste in the northern Adriatic Sea. This coastal area supports seagrass meadows and nursery habitats for fish, making nutrient management critical to prevent eutrophication. The plant's treatment level helps maintain the ecological balance of the river and downstream marine environment.
Frequently asked questions
The GORIZIA plant is located in Gorizia, in the Friuli-Venezia Giulia region of northeastern Italy, near the border with Slovenia.
The plant serves a population equivalent of approximately 33,045 people, classifying it as a medium-sized agglomeration under EU regulations.
The treated effluent is discharged into the local water system, which drains into the Isonzo River (Soča) and eventually reaches the Gulf of Trieste in the Adriatic Sea.
As an Italian plant, GORIZIA operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations over 10,000 people and may require tertiary treatment in sensitive areas.
For medium-sized agglomerations in Italy, secondary treatment is standard under the EU directive. If the receiving water body is sensitive, advanced treatment with nutrient removal may be required.
