ZV Esselbachgrund Sitz Esselbach Wastewater Treatment Plant, Kredenbach, Germany

ZV Esselbachgrund Sitz Esselbach is a wastewater treatment plant located in Kredenbach, a district of Esselbach in Bavaria, Germany. The plant serves a population of around 3,947 people, placing it in the small agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). As a German facility, the plant operates under the EU UWWTD, which requires secondary treatment for agglomerations of this size. It is expected to meet national standards for biological treatment and nutrient removal where applicable. The plant discharges treated effluent into the local water system, ultimately draining into the Main River basin, which flows into the Rhine and then the North Sea. The surrounding region is characterized by mixed agricultural and forested land, with the plant playing a key role in protecting local streams and groundwater quality.

The plant's treated effluent enters the Salzbach stream, a tributary of the Main River. The Main flows westward to join the Rhine, which discharges into the North Sea. The local watershed supports diverse aquatic life and is part of a region with sensitive groundwater resources. Proper treatment helps prevent nutrient pollution and maintains ecological balance in the downstream river system.
