Diesdorf Wastewater Treatment Plant, Sachsen-Anhalt, Germany

The Diesdorf wastewater treatment plant is located in the municipality of Diesdorf, within the Altmarkkreis Salzwedel district of Sachsen-Anhalt, Germany. It serves a population of approximately 3,241 residents, classifying it as a small agglomeration under German and EU regulations. The plant employs advanced treatment processes, which go beyond 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 3,600 m³/day and an average discharge volume of 271.87 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the Elbe River basin. The Elbe flows through northern Germany into the North Sea, supporting diverse aquatic ecosystems and serving as an important migratory corridor for fish species. The advanced treatment helps protect these downstream environments from nutrient pollution.

The plant discharges into small streams within the Elbe River basin, which flows northward through Germany to the North Sea. The Elbe estuary and coastal waters are ecologically sensitive areas that support diverse aquatic life, including migratory fish and bird populations. Advanced treatment at this plant helps reduce nutrient loads that could contribute to eutrophication in the North Sea.
