Langenwang_Murz I Wastewater Treatment Plant, Langenwang, Styria, Austria

Langenwang_Murz I is a municipal wastewater treatment plant located in Langenwang, a town in the Bruck-Mürzzuschlag district of Styria, Austria. The plant serves a population of approximately 23,745, classifying it as a medium-sized agglomeration under EU regulations. As an Austrian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant is expected to meet these EU standards. The treated effluent is discharged into the local water system, which ultimately drains into the Murz River, a tributary of the Mur River. The Mur flows through Styria and into Slovenia, eventually reaching the Drava and the Danube. This river system supports diverse aquatic life and is important for regional water quality.

The plant discharges into the Murz River, a tributary of the Mur River, which flows through Styria and into Slovenia before joining the Drava and eventually the Danube River, which empties into the Black Sea. The Mur River basin supports diverse aquatic ecosystems and is an important migratory corridor for fish species. The region's water quality is managed under the EU Water Framework Directive, aiming to achieve good ecological status.
