Tuntenhausen OT Hohenthann Wastewater Treatment Plant, Lorenzenberg, Bavaria

Tuntenhausen OT Hohenthann is a former wastewater treatment plant located in Lorenzenberg, a district of Tuntenhausen in the Bavarian region of Germany. The plant served a small population of 1,214 people and was designed with a capacity of 3,500 m³ per day. It provided secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive for agglomerations of this size. As a secondary treatment facility, the plant would have removed organic matter and suspended solids through biological processes. Although the plant is now closed, its design capacity suggests it was built to accommodate future growth or seasonal variations. The plant's operational status indicates that the local wastewater infrastructure has been consolidated or upgraded to a newer facility. The plant discharged treated wastewater into local water bodies within the Bavarian watershed, which ultimately drains into the Danube River basin and then into the Black Sea. The region is characterized by a mix of agricultural and residential areas, and the plant's operation would have helped protect local streams and groundwater from untreated sewage.

The area drains into the Mangfall River, a tributary of the Inn River, which flows into the Danube and eventually the Black Sea. The local watershed supports diverse aquatic life and is part of a region with sensitive groundwater resources. Proper wastewater treatment is essential to prevent nutrient pollution and maintain water quality in these downstream ecosystems.
