FOSSO DEL LUPO Wastewater Treatment Plant, Cepagatti, Italy

FOSSO DEL LUPO is a wastewater treatment plant located in Cerratina, a locality within the municipality of Cepagatti, in the province of Pescara, Abruzzo, Italy. The plant serves a population of approximately 3,100 people, classifying it as a small agglomeration under Italian and EU regulations. As a plant serving fewer than 10,000 population equivalents, it falls under the scope of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on the sensitivity of the receiving waters. Italian plants of this scale typically employ secondary biological treatment to meet national discharge standards. The plant's treated effluent ultimately drains into the Adriatic Sea via local watercourses. The Adriatic Sea is a semi-enclosed basin with sensitive ecological zones, including seagrass meadows and important fisheries. The plant's proximity to the coast (within 50 km) underscores the importance of effective nutrient removal to prevent eutrophication in coastal waters.

The plant discharges into the local hydrographic network that flows toward the Adriatic Sea, a semi-enclosed basin with limited water exchange. The Adriatic supports diverse marine life, including Posidonia oceanica seagrass meadows and commercial fish species. Nutrient loading from wastewater can contribute to algal blooms and hypoxia in coastal areas, making treatment standards critical for preserving water quality and ecosystem health.
