UWWTP Zagorje ob Savi Kotredez - Secondary Wastewater Treatment in Zagorje ob Savi, Slovenia

UWWTP Zagorje ob Savi Kotredez is a wastewater treatment facility located in Zagorje ob Savi, Slovenia. The plant serves a small population of 42 people, reflecting its role in a rural or small community setting within the Savinja River basin. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 1900 suggests the plant is built to accommodate future growth or seasonal variations. The actual discharge volume is 6.56, indicating current operational levels. The treated effluent is discharged into the local water system, which ultimately drains into the Sava River and then the Danube River basin. This downstream connection to the Black Sea highlights the plant's role in protecting regional water quality and supporting aquatic ecosystems in the broader Danube watershed.

The plant discharges into the Sava River basin, a major tributary of the Danube River, which flows into the Black Sea. The local watershed supports diverse aquatic life and is important for migratory fish species. The secondary treatment helps reduce organic pollutants and nutrients, protecting downstream water quality in this ecologically sensitive region.
