ZV Hungerbachtal Wastewater Treatment Plant, Peißenberg, Bavaria

ZV Hungerbachtal is a municipal wastewater treatment plant located in Peißenberg, in the Bavarian district of Weilheim-Schongau, Germany. The facility serves a population of approximately 5,600 residents and is designed to handle up to 7,000 cubic meters of wastewater per day, with an average daily discharge of 881.86 cubic meters. 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies, aligning with Germany's stringent national standards for wastewater treatment. The treated effluent is discharged into local waterways that ultimately drain into the Danube River basin, contributing to the protection of the Black Sea ecosystem. The plant plays a key role in maintaining water quality in the region, supporting both ecological health and downstream water uses.

The plant discharges into local streams that feed into the Ammer River, a tributary of the Danube. The Danube flows through multiple countries before reaching the Black Sea, making the plant's advanced treatment crucial for reducing nutrient loads that could cause eutrophication in downstream lakes and coastal areas. The surrounding region includes sensitive aquatic habitats that benefit from the plant's high treatment standards.
