Overview
Dingolfing wastewater treatment plant serves approximately 60,000 people in Gottfrieding, Bavaria, Germany. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Dingolfing wastewater treatment plant is located in Gottfrieding, a municipality in the Landkreis Dingolfing-Landau district of Bavaria, Germany. It serves a population of approximately 59,839 people, classifying it as a medium-to-large agglomeration under EU regulations. As a German plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations over 2,000 population equivalent and tertiary treatment in sensitive areas. The plant's treatment processes and capacity are designed to meet these standards, ensuring compliance with national and EU water quality regulations. The treated effluent is discharged into the local watershed, which ultimately drains into the Isar River, a tributary of the Danube. The Danube flows into the Black Sea, making this plant part of a large international river basin. The surrounding region is characterized by agricultural land and small settlements, and the plant plays a key role in protecting downstream water quality and aquatic ecosystems.
Environmental context
The plant discharges into the Isar River basin, which flows into the Danube River and eventually reaches the Black Sea. This watershed supports diverse aquatic life, including fish species such as grayling and brown trout, and is an important ecological corridor in Bavaria. The plant's treatment helps maintain water quality in this sensitive river system, which is used for recreation and agriculture downstream.

The treated effluent is discharged into the local watershed, which drains into the Isar River, a tributary of the Danube River, and ultimately reaches the Black Sea.
Under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant must provide at least secondary treatment. For agglomerations over 10,000 population equivalent in sensitive areas, tertiary treatment is required. Germany implements this directive through national legislation.
In Germany, plants serving approximately 60,000 people typically employ secondary biological treatment, often with nutrient removal (nitrogen and phosphorus) to meet EU standards for sensitive areas. Many also include tertiary filtration or disinfection.
