Frojach Katsch Wastewater Treatment Plant, Teufenbach-Katsch, Styria, Austria

Frojach Katsch is a wastewater treatment plant located in Teufenbach-Katsch, in the Murau district of Styria, Austria. The facility serves a population of 3,313 and is designed with an advanced treatment level, reflecting high environmental standards. With a designed capacity of 5,300 m³/day and a discharge volume of 556.23 m³/day, the plant operates well below its capacity. As an Austrian facility, it complies with the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and secondary treatment for all discharges. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Mur River, a tributary of the Drava and later the Danube. This river system supports diverse aquatic life and is important for regional water quality and biodiversity.

The plant discharges into the Mur River basin, which flows through Styria and into Slovenia, eventually reaching the Drava and Danube rivers. The Mur River supports a variety of fish species and is an important ecological corridor in the region. The advanced treatment level helps protect downstream water quality and aquatic habitats.
