Mureck Wastewater Treatment Plant - Steiermark, Slovenia

The Mureck wastewater treatment plant is located in the town of Mureck, in the Steiermark region of Slovenia, near the Austrian border. The facility serves a population of approximately 1,888 people, classifying it as a small agglomeration under EU regulations. It operates with advanced treatment, ensuring high-quality effluent before discharge. As a small plant in Slovenia, it falls under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The advanced treatment level suggests additional nutrient removal or polishing, common in sensitive areas. The plant's designed capacity of 9,000 m³/day indicates room for future growth, while current discharge volume is 610.15 m³/day. The treated effluent is discharged into local waterways, likely tributaries of the Mur River, which flows into the Drava and eventually the Danube River basin. The Danube drains into the Black Sea, making this plant part of a vast transboundary watershed. The region supports diverse aquatic life and is ecologically sensitive, with the plant's advanced treatment helping to protect downstream water quality.

The plant discharges into the Mur River catchment, part of the Danube River basin, which ultimately flows into the Black Sea. The Mur River supports diverse aquatic ecosystems, including fish species like grayling and brown trout. The advanced treatment helps minimize nutrient loading, protecting downstream habitats from eutrophication.
