Triebes Wastewater Treatment Plant, Greiz, Thüringen, Germany

Triebes wastewater treatment plant is located in the Greiz district of Thüringen, Germany, serving a population of approximately 3,501. The plant is situated in the town of Triebes, part of the municipality of Zeulenroda-Triebes, and operates as a key facility for local wastewater management. The plant employs advanced treatment processes, exceeding the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,800 m³/day and an actual discharge volume of 748.40 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. Treated effluent is discharged into local watercourses that ultimately drain into the White Elster River, a tributary of the Saale River, which flows into the Elbe and then the North Sea. The plant plays a vital role in protecting the water quality of these rivers and the downstream aquatic ecosystems.

The plant discharges into the Triebes stream, a tributary of the White Elster River, which flows through Thüringen and Saxony-Anhalt before joining the Saale River. The Saale then drains into the Elbe, which empties into the North Sea. The region's water bodies support diverse aquatic life, including fish species such as brown trout and grayling, and the plant's advanced treatment helps maintain ecological balance in this sensitive watershed.
