AVIANO_CASTELLO Wastewater Treatment Plant, Aviano, Italy

AVIANO_CASTELLO is a wastewater treatment plant located in the municipality of Aviano/Davian, in the province of Pordenone, Friuli-Venezia Giulia, Italy. The plant serves a population of approximately 7,788, placing it in the small-to-medium agglomeration category under EU classification. Its location in the Alpine foothills of northeastern Italy influences the local water management context. As an Italian plant serving fewer than 10,000 people, AVIANO_CASTELLO operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires appropriate treatment for discharges into freshwater. Regulatory compliance is expected under Italian national implementation of EU directives. The plant's treated effluent likely discharges into local watercourses that drain into the Livenza or Meduna river systems, eventually reaching the Adriatic Sea. These rivers support diverse aquatic ecosystems and are important for regional water quality. The plant plays a key role in protecting local streams and downstream environments from untreated wastewater, contributing to the ecological health of the Friuli-Venezia Giulia region.

AVIANO_CASTELLO's treated wastewater likely enters local tributaries of the Livenza or Meduna rivers, which flow southward through the Veneto-Friuli plain into the Adriatic Sea. The downstream environment includes sensitive freshwater habitats that support fish populations and migratory birds. The plant's location near the Alpine foothills means its discharge affects small streams that are ecologically important for maintaining water quality and biodiversity in the region.
