Overview
GRADO wastewater treatment plant serves approximately 33,664 people in Italy. Located near the coast, it operates under the EU Urban Waste Water Treatment Directive.
The GRADO wastewater treatment plant is situated in Italy, serving a population of around 33,664. As a medium-sized agglomeration, the facility is part of the country's municipal wastewater infrastructure, handling domestic and industrial wastewater from the area. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving between 10,000 and 150,000 population equivalent are required to provide secondary treatment, with tertiary treatment mandated in sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized appropriately for its service population. The plant discharges treated effluent into the local water environment, ultimately draining into the Adriatic Sea. Its coastal location means the discharge may affect sensitive marine ecosystems, including seagrass beds and fish nurseries. Proper treatment is essential to protect water quality and biodiversity in the Gulf of Trieste.
Environmental context
The plant's treated effluent flows into the Adriatic Sea via local watercourses. The Gulf of Trieste is a semi-enclosed basin with limited water exchange, making it sensitive to nutrient inputs. The area supports diverse marine life, including seagrass meadows and commercial fish species. Effective wastewater treatment helps prevent eutrophication and protects coastal habitats.
Frequently asked questions
The GRADO wastewater treatment plant is located in Italy, near the coast of the Adriatic Sea. Its coordinates are approximately 45.671 N, 13.507 E.
The plant serves a population of approximately 33,664 people, classifying it as a medium-sized agglomeration under EU regulations.
The plant discharges treated effluent into local water bodies that flow into the Adriatic Sea. Being within 50 km of the coast, the discharge may directly or indirectly reach marine waters.
Under the EU UWWTD (91/271/EEC), plants serving 10,000 to 150,000 population equivalent must provide secondary treatment. As a coastal plant, it may also require additional treatment to protect sensitive marine areas.
Italian plants of this scale typically employ secondary biological treatment, such as activated sludge, to meet EU standards. In coastal or sensitive areas, tertiary treatment for nutrient removal may be required.
