UWWTP Bohinjska Bistrica - Secondary Wastewater Treatment Plant in Slovenia

UWWTP Bohinjska Bistrica is a municipal wastewater treatment plant located in Bohinjska Bistrica, a town in the Upper Carniola region of Slovenia. The plant serves a population of approximately 1,000 residents and is part of the country's infrastructure for managing domestic wastewater in the Julian Alps area. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 2,000 cubic meters per day, with an average discharge volume of about 157 cubic meters per day, indicating it operates well below its capacity. The treated effluent is discharged into a local watercourse that eventually flows into the Sava River, a major tributary of the Danube. The plant plays a key role in protecting the sensitive alpine environment and the downstream aquatic ecosystems, including the Sava River and its biodiversity.

The plant discharges into a small stream that feeds the Sava Bohinjka River, which flows through the Triglav National Park area before joining the Sava River. The Sava River ultimately drains into the Danube River and the Black Sea. The surrounding watershed is ecologically sensitive, supporting diverse aquatic life and serving as an important corridor for migratory fish species. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding water quality in this alpine region.
