PRADER_SAND Wastewater Treatment Plant, St. Peter - San Pietro, Italy

PRADER_SAND is a wastewater treatment plant located in St. Peter - San Pietro, a village in the municipality of Villnöß - Funes, within the autonomous province of Bolzano - Bozen, Trentino-Alto Adige/Südtirol, Italy. The plant serves a population of approximately 8,335 people, placing it in the small-to-medium agglomeration category under Italian and EU regulations. As a plant of this scale in Italy, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland freshwater discharges from agglomerations of this size. The plant's treatment process and capacity details are not publicly available, but the regulatory framework ensures compliance with national standards for effluent quality. The plant discharges into a local watercourse that eventually drains into the Isarco River (Eisack), a tributary of the Adige River, which flows into the Adriatic Sea. The surrounding area is part of the Dolomites, a UNESCO World Heritage site, and the plant plays a key role in protecting the region's sensitive alpine aquatic ecosystems.

The plant's treated effluent enters a small stream that flows into the Isarco River (Eisack), a major tributary of the Adige River. The Adige River ultimately discharges into the Adriatic Sea near Venice. The region is characterized by alpine watersheds with high ecological sensitivity, supporting diverse aquatic life and serving as an important corridor for migratory fish species. The plant's operation helps maintain water quality in this ecologically significant area.
