StMarein_Murz III is a municipal wastewater treatment plant located in Gassing, a locality in Sankt Lorenzen im Mürztal, Steiermark, Austria. The plant serves a population of approximately 22,408, classifying it as a medium 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 with a population equivalent (PE) between 10,000 and 150,000. For inland areas, this standard ensures effective removal of organic matter and nutrients to protect receiving waters. The plant discharges treated effluent into the local watershed, which ultimately drains into the Mur River, a major tributary of the Drava River, and then into the Danube River basin. The Mur River supports diverse aquatic life and is an important ecological corridor in the region. Proper treatment helps maintain water quality in this sensitive river system.
