C_DA_S_MARIA_IN_POTENZA_PTR_DEP is a wastewater treatment plant located in Porto Recanati, in the Marche region of Italy. The plant serves a population equivalent of 43,556, classifying it as a medium agglomeration under EU regulations. It is situated near the Adriatic coast, within 50 km of the sea, and its address along the Autostrada Adriatica places it in a coastal urban setting. As a plant in Italy, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. The directive also mandates more stringent treatment if the discharge enters sensitive areas, such as coastal waters prone to eutrophication. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a moderate scale of operation. The treated effluent from this plant is discharged into the Adriatic Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The local watershed includes the Potenza River and other minor coastal streams. The plant plays a key role in protecting the coastal marine environment and supporting tourism and fisheries in the region.
Environmental context
The plant discharges into the Adriatic Sea, a semi-enclosed basin that receives inflows from the Po River and numerous smaller rivers along the Italian coast. The Adriatic is ecologically sensitive due to its shallow depth and limited water exchange, making it prone to eutrophication from nutrient inputs. The local watershed includes the Potenza River, which drains agricultural and urban areas before reaching the coast. Protecting this marine environment is critical for biodiversity, including seagrass meadows and fish nurseries, as well as for tourism and fishing industries.
Frequently asked questions
The plant is located on the Autostrada Adriatica in Porto Recanati, in the province of Macerata, Marche region, Italy.
The plant serves a population equivalent of 43,556, classifying it as a medium agglomeration under EU regulations.
The treated effluent is discharged into the Adriatic Sea, likely via a coastal outfall. The plant is within 50 km of the coast.
Under the EU UWWTD (91/271/EEC), agglomerations of 43,556 PE require at least secondary treatment. If the receiving waters are sensitive, tertiary treatment may be needed.
In Italy, plants of this scale typically employ secondary biological treatment (activated sludge or similar) to meet EU standards. Many also include nutrient removal to protect the Adriatic Sea.
