Teunz Wastewater Treatment Plant, Niedermurach, Bavaria

Teunz wastewater treatment plant is located in the Voggendorf area of Niedermurach, a municipality in the Schwandorf district of Bavaria, Germany. The plant served a population of approximately 916 people and was designed with a capacity of 2,300 cubic meters per day. It is now closed. The plant provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for all discharges from agglomerations with a population equivalent above 2,000, but smaller plants like Teunz may also apply secondary treatment to meet local water quality objectives. The treated effluent from the plant was discharged into local watercourses that drain into the Naab River, a tributary of the Danube. The Danube ultimately flows into the Black Sea. The surrounding region is characterized by rural landscapes and small communities, with the plant playing a role in protecting local streams and groundwater quality.

The plant's discharge likely entered small streams in the Naab River basin, which flows into the Danube River and eventually the Black Sea. The region supports diverse aquatic life and is part of a larger watershed that includes sensitive ecosystems. Proper treatment helps maintain water quality for downstream communities and habitats.
