Kleinrinderfeld Wastewater Treatment Plant, Bavaria, Germany

The Kleinrinderfeld wastewater treatment plant is located in the municipality of Kleinrinderfeld, in the Bavarian district of Würzburg, Germany. It serves a population of approximately 2,004 residents, placing it within the small agglomeration category under EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The facility has a designed capacity of 3,500 cubic meters per day and currently treats an average daily flow of 507.16 cubic meters, indicating ample reserve capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Main River, a major tributary of the Rhine. The Rhine basin supports diverse aquatic life and is an important ecological corridor in Central Europe. The plant's operation contributes to maintaining water quality in this sensitive river system.

The plant discharges into the local watershed that feeds the Main River, which flows into the Rhine. The Rhine basin is a critical ecological corridor supporting diverse fish species and migratory birds. The region's agricultural and urban runoff can impact water quality, making the plant's secondary treatment essential for protecting downstream ecosystems.
