Markt Wald Wastewater Treatment Plant, Mittelneufnach, Bavaria

Markt Wald is a wastewater treatment plant located in Mittelneufnach, a village in the Bavarian district of Augsburg, Germany. The plant serves a population of approximately 2,433 people, reflecting its role in a small rural community. It is situated in the Stauden region, an area characterized by rolling hills and agricultural land. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,000 cubic meters per day and an actual discharge volume of 615.73 cubic meters per day, the facility operates well below its capacity, indicating room for future growth or seasonal fluctuations. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin. The Danube flows eastward through Central and Eastern Europe before reaching the Black Sea. The plant's advanced treatment helps protect the sensitive freshwater ecosystems in the region, including streams that support diverse aquatic life and contribute to the ecological health of the Danube watershed.

The plant discharges into small streams in the Stauden region, which are part of the Danube River basin. These streams flow into the Wertach and Lech rivers, tributaries of the Danube, which eventually reaches the Black Sea. The area supports diverse aquatic habitats, including fish species such as brown trout and grayling, and the advanced treatment helps maintain water quality in these ecologically sensitive headwaters.
