Santo Stefano d'Aveto Wastewater Treatment Plant | Liguria, Italy

The S_STEFANO_D_AVETO_CAPOLUOGO wastewater treatment plant is located in Santo Stefano d'Aveto, a municipality in the Liguria region of northern Italy. The plant serves a population of approximately 4,400 residents and operates with secondary treatment, which is standard for smaller agglomerations under Italian and EU regulations. With a designed capacity of 5,400 cubic meters per day and a discharge volume of 871 cubic meters per day, the plant operates well within its capacity. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids, meeting the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant discharges treated effluent into the local watershed, which ultimately drains into the Ligurian Sea via the Aveto River and other watercourses. The region is characterized by mountainous terrain and is part of the Aveto Natural Regional Park, an ecologically sensitive area that supports diverse aquatic life and forest ecosystems.

The plant discharges into the Aveto River basin, a tributary of the Trebbia River, which flows into the Po River and eventually the Adriatic Sea. The surrounding area is part of the Aveto Natural Regional Park, a protected area with rich biodiversity, including rare plant species and wildlife such as the Apennine wolf. The treatment plant helps protect these sensitive ecosystems by reducing nutrient and pollutant loads.
