Caramanico Capoluogo Wastewater Treatment Plant, Caramanico Terme, Italy

Caramanico Capoluogo is a municipal wastewater treatment plant located in Caramanico Terme, a town in the province of Pescara, Abruzzo, Italy. The facility serves a population of approximately 3,100 people, reflecting its role as a medium-small agglomeration in the region. The plant is situated inland, more than 10 km from the Adriatic coast, and operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the standard required by the EU directive for freshwater discharges from agglomerations of this size. With a designed capacity of 4,000 m³/day and a current discharge volume of about 931.51 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. Treated effluent from the plant is discharged into a local watercourse that eventually flows into the Adriatic Sea via the Aterno-Pescara river system. This discharge contributes to the ecological health of the downstream environment, supporting aquatic life and maintaining water quality in the sensitive coastal zone of the Adriatic. The plant's operation is subject to Italian national regulations and EU standards, ensuring compliance with environmental protection goals.

The plant discharges into a local tributary of the Aterno-Pescara river basin, which flows eastward to the Adriatic Sea. The Adriatic coast near Pescara is an ecologically sensitive area, supporting diverse marine life and important fisheries. The secondary treatment provided helps reduce organic pollutants and nutrients, protecting downstream water quality and preventing eutrophication in the coastal zone.
