UWWTP_MOZIRJE Wastewater Treatment Plant, Loke pri Mozirju, Slovenia

UWWTP_MOZIRJE is a municipal wastewater treatment plant located in Loke pri Mozirju, a settlement in the municipality of Mozirje, Slovenia. The plant serves a population of approximately 5,759 people, classifying it as a small to medium agglomeration under Slovenian and EU regulations. It operates as part of the country's wastewater infrastructure, which is regulated under the EU Urban Waste Water Treatment Directive (UWWTD). The plant provides secondary treatment, a standard requirement under the UWWTD for inland freshwater discharges from agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's designed capacity is 3,000 m³/day, and it discharges an average volume of 899.52 m³/day, indicating operational capacity below design levels. The treated effluent is discharged into a local watercourse that ultimately drains into the Savinja River, a tributary of the Sava River, which flows into the Danube River and eventually the Black Sea. The plant plays a crucial role in protecting the local watershed and downstream ecosystems from untreated wastewater pollution, supporting water quality in the Savinja catchment area.

The plant discharges into a local stream that flows into the Savinja River, a major river in Slovenia's Savinja Valley. The Savinja joins the Sava River near Zidani Most, and the Sava flows into the Danube at Belgrade, Serbia, ultimately reaching the Black Sea. The watershed supports diverse aquatic life and is used for recreation and agriculture. Protecting this water body from nutrient and organic pollution is critical for maintaining ecological balance and meeting EU Water Framework Directive goals.
