Overview
AZV Obere Maisach is a wastewater treatment plant serving Nassenhausen, Bavaria, Germany. It treats wastewater for approximately 5,400 people as part of the region's municipal infrastructure.
AZV Obere Maisach is a wastewater treatment plant located in Nassenhausen, a village in the district of Fürstenfeldbruck, Bavaria, Germany. The plant serves a population of approximately 5,400 residents, making it a small to medium-sized facility within the region's wastewater management network. As a German wastewater treatment plant, AZV Obere Maisach operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection, treatment, and discharge of urban wastewater. For agglomerations of this scale (5,400 population equivalent), the directive requires at least secondary treatment, with possible additional requirements if the receiving waters are designated as sensitive areas. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin. The region's aquatic ecosystems benefit from proper wastewater treatment, which helps maintain water quality in streams and rivers that support diverse freshwater life and contribute to the ecological health of the broader Danube watershed.
Environmental context
The plant's discharge flows into small streams in the Maisach valley, which are part of the Amper river system, a tributary of the Isar. The Isar joins the Danube, which flows into the Black Sea. The local watershed supports aquatic habitats typical of Bavarian lowland streams, including fish species such as brown trout and grayling, and is ecologically sensitive to nutrient loading from wastewater.
