ZV Abwasserbeseitigung Rotmaintal - Wastewater Treatment Plant in Unterobsang, Bavaria

ZV Abwasserbeseitigung Rotmaintal is a municipal wastewater treatment plant located in Unterobsang, a district of Neudrossenfeld in the Landkreis Kulmbach, Bavaria, Germany. The plant serves a population of approximately 3,993 people, placing it in the small agglomeration category under EU regulations. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000. The directive also mandates appropriate collection systems and treatment to protect receiving waters. The plant's location in the Rot-Main-Auen area suggests it discharges into the Roter Main river system. The plant's treated effluent likely discharges into the Roter Main, a tributary of the Main River, which flows into the Rhine and ultimately the North Sea. This catchment supports diverse aquatic life and is part of a major European waterway. The plant's operation helps protect local water quality in the Kulmbach district, an area characterized by mixed agricultural and small-scale industrial activity.

The plant discharges into the Roter Main river, a headwater tributary of the Main River. The Main flows westward to join the Rhine, which empties into the North Sea. This river system supports diverse aquatic ecosystems, including fish species such as barbel and chub, and provides habitat for migratory birds along the Rhine corridor. The plant's treatment helps maintain water quality in this ecologically sensitive catchment.
