FONTE_VANNAZZA_TRE_DEP Wastewater Treatment Plant, Treia, Italy

FONTE_VANNAZZA_TRE_DEP is an advanced wastewater treatment plant located in San Marco, Treia, in the Macerata province of Italy. The plant serves a population of 1,841 and has a designed capacity of 1,500 m³/day, with a current discharge volume of 364.45 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For small agglomerations like Treia, the directive requires appropriate treatment, and advanced treatment is often implemented in sensitive areas to protect water quality. The plant discharges treated wastewater into local watercourses that eventually drain into the Adriatic Sea. Its advanced treatment helps safeguard downstream ecosystems, including rivers and coastal waters, from nutrient pollution and other contaminants, supporting aquatic life and regional water quality.

The plant's treated effluent flows into local streams and rivers within the Potenza River basin, ultimately reaching the Adriatic Sea. This coastal region supports diverse marine life and is important for tourism and fishing. Advanced treatment reduces nutrient loads, helping to prevent eutrophication and protect the ecological balance of the Adriatic coastal zone.
