Nordheim_Main Wastewater Treatment Plant, Nordheim am Main, Bavaria

Nordheim_Main is a municipal wastewater treatment plant located in Nordheim am Main, Bavaria, Germany. The plant serves a population of approximately 3,161 residents and has a designed capacity of 10,000 m³/day, indicating it is sized to accommodate future growth or seasonal fluctuations. It operates under the German water management framework, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. For a small agglomeration of this size, secondary treatment meets the standard requirements under the EU directive. The plant's discharge volume is reported at 283.94 m³/day, suggesting it operates well below its designed capacity. Treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Main River, a major tributary of the Rhine. The Rhine basin is ecologically significant, supporting diverse aquatic life and serving as an important migratory corridor for fish species. The plant's location inland, away from coastal areas, reduces direct marine impact but still requires careful management to protect local water quality.

The plant discharges into the Main River basin, which flows into the Rhine River and eventually the North Sea. The Rhine is a vital European waterway supporting diverse ecosystems, including fish species such as salmon and eel. The plant's secondary treatment helps reduce nutrient loads, protecting downstream water quality in this ecologically sensitive river system.
