Rocca di Cambio Wastewater Treatment Plant - L'Aquila, Italy

The Rocca di Cambio wastewater treatment plant is located in the municipality of Rocca di Cambio, within the province of L'Aquila in the Abruzzo region of Italy. The facility serves a population of approximately 2,917 residents, operating as a secondary treatment plant under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). As a secondary treatment plant, Rocca di Cambio employs biological processes to reduce organic matter and suspended solids, meeting the standard requirements for agglomerations of this size. The plant has a designed capacity of 1,500 m³/day and currently treats an average daily flow of 577.46 m³, indicating operational capacity well within design limits. Italian wastewater treatment facilities are regulated by national decrees that transpose EU directives, ensuring compliance with discharge standards. The plant discharges treated effluent into the local watershed, which ultimately drains into the Adriatic Sea via the Aterno-Pescara river system. The receiving water bodies support diverse aquatic life and are part of the broader Apennine mountain ecosystem. Proper treatment at this facility helps protect downstream water quality and the ecological health of the Adriatic coastal zone.

The plant's treated effluent enters the local drainage network within the Aterno River basin, which flows eastward through the Abruzzo region to the Adriatic Sea. The watershed supports diverse aquatic habitats, including cold-water fish species and riparian vegetation. Downstream waters are used for irrigation and recreation, making effective nutrient and pathogen removal critical for protecting both ecological integrity and human uses.
