TRECCHINA_PARRUTTA Wastewater Treatment Plant, Trecchina, Basilicata, Italy

TRECCHINA_PARRUTTA is a municipal wastewater treatment plant located in Fondovalle del Noce, Trecchina, in the Basilicata region of southern Italy. The plant serves a small population of 310 people, reflecting its role in a rural or small-town community. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent (PE) between 2,000 and 10,000. Although the designed capacity is 2,000 m³/day, the actual discharge volume is 61.37 m³/day, indicating low utilization. The plant's treated effluent is discharged into the local water environment, ultimately reaching the Tyrrhenian Sea via the Noce River or nearby coastal waters. Its proximity to the coast (within 10 km) means the discharge may affect coastal water quality and marine ecosystems, which are subject to EU Bathing Water Directive and Marine Strategy Framework Directive requirements.

The plant discharges into the Fondovalle del Noce area, which drains into the Noce River and then into the Tyrrhenian Sea. The coastal zone supports diverse marine life and is used for recreation and fishing. As a coastal plant, it must meet stringent standards to protect sensitive marine habitats from nutrient pollution and pathogens.
