Elbbachtal GKA Hartlingen Wastewater Treatment Plant, Elbingen, Germany

Elbbachtal GKA Hartlingen is a wastewater treatment plant located in Elbingen, within the Westerwaldkreis district of Rheinland-Pfalz, Germany. The plant serves a population of around 5,247, classifying it as a small agglomeration under EU regulations. It is situated inland, more than 50 km from the coast, and discharges into local watercourses that ultimately drain into the Rhine basin. As a German plant serving fewer than 10,000 people, Elbbachtal GKA Hartlingen operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for small agglomerations. German plants of this scale typically employ biological treatment stages to meet national water quality standards. The treated effluent from Elbbachtal GKA Hartlingen is discharged into local streams that flow into the Elbbach, a tributary of the Lahn River, which eventually joins the Rhine. This catchment supports diverse aquatic life and is part of a broader river system that drains into the North Sea. The plant plays a key role in protecting local water quality in the Westerwald region.

The plant discharges into the Elbbach, a small river that flows into the Lahn, a major tributary of the Rhine. The Rhine basin is one of Europe's most important waterways, supporting diverse ecosystems and providing drinking water for millions. The local watershed in the Westerwald region is characterized by forested hills and agricultural land, making nutrient management critical to prevent eutrophication in downstream rivers and the North Sea.
