CAPPELLE_DEI_MARSI Wastewater Treatment Plant, Cese dei Marsi, Italy

CAPPELLE_DEI_MARSI is a wastewater treatment plant located in Cese dei Marsi, a frazione of Scurcola Marsicana in the province of L'Aquila, Abruzzo, Italy. The plant provides secondary treatment for a population equivalent of approximately 3,590, with a designed capacity of 1,200 cubic meters per day and an average discharge volume of 710.69 cubic meters per day. As a secondary treatment facility, the plant meets the minimum treatment standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations between 2,000 and 10,000 population equivalent. The directive mandates secondary treatment for all inland discharges from agglomerations of this size, ensuring compliance with European water quality standards. The plant discharges treated effluent into the local watershed, which ultimately drains into the Tyrrhenian Sea via the Liri-Garigliano river system. The receiving water body supports diverse aquatic life and is part of a region known for its ecological sensitivity, including the nearby Abruzzo, Lazio and Molise National Park. Proper treatment helps protect downstream water quality and biodiversity.

The plant discharges into the Liri-Garigliano river basin, which flows through central Italy and empties into the Tyrrhenian Sea near the Gulf of Gaeta. This watershed supports diverse aquatic ecosystems, including fish species such as trout and eels, and provides water for agriculture and human use. The region is ecologically sensitive, with protected areas like the Abruzzo, Lazio and Molise National Park located upstream, making effective wastewater treatment critical for maintaining water quality and habitat integrity.
