Overview
STAMSRIED wastewater treatment plant in Pösing, Bayern, Germany, serves approximately 1,700 people with secondary treatment. The plant is now closed.
STAMSRIED is a former wastewater treatment plant located in Pösing, within the municipality of Stamsried in the Cham district of Bavaria, Germany. It served a population of about 1,700 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant provided secondary treatment, which is the minimum standard required by the UWWTD for freshwater discharges from agglomerations of this size. As a German facility, STAMSRIED operated under the national implementation of the EU UWWTD, which mandates secondary treatment for all discharges to freshwater and estuaries. The plant's designed capacity was 3,500 cubic meters per day, and its average daily discharge volume was approximately 430 cubic meters. The plant is now closed, and its wastewater management responsibilities have likely been transferred to a larger regional facility. The plant's treated effluent was discharged into local watercourses that ultimately drain into the Danube River basin via the Regen River system. The Danube flows into the Black Sea, making this plant part of a vast international watershed. The surrounding region is characterized by mixed agricultural and forested landscapes, with sensitive aquatic habitats that benefit from proper wastewater treatment.
Environmental context
The STAMSRIED plant discharged into small streams within the Regen River catchment, which feeds into the Danube River and eventually the Black Sea. This watershed supports diverse aquatic life, including fish species such as Danube salmon and various cyprinids. The region's groundwater and surface waters are ecologically sensitive, requiring effective nutrient removal to prevent eutrophication in downstream lakes and the Black Sea.
