Obermohr Wastewater Treatment Plant: Serving Obermohr, Rhineland-Palatinate

The Obermohr wastewater treatment plant is located in the municipality of Obermohr, part of the Steinwenden collective municipality in the district of Kaiserslautern, Rhineland-Palatinate, Germany. The plant serves a population of around 3,946 people, placing it in the small agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). As a German wastewater treatment facility, Obermohr operates under the national implementation of the EU UWWTD, which requires secondary treatment for all agglomerations above 2,000 population equivalent. For smaller plants like Obermohr, appropriate treatment must ensure compliance with receiving water quality standards. The plant's design and operation are subject to state-level water management regulations. The treated effluent from Obermohr is discharged into local watercourses that are part of the Rhine River basin. The Rhine is one of Europe's major rivers, flowing through Germany and the Netherlands before reaching the North Sea. The plant's operations help protect the ecological health of these waterways, supporting aquatic life and downstream water quality.

Obermohr lies within the catchment of the Rhine River, which drains into the North Sea. The local watershed includes small streams that feed into the Glan, a tributary of the Nahe, which joins the Rhine near Bingen. The Rhine basin supports diverse aquatic ecosystems and is an important migratory corridor for fish. The plant's discharge contributes to maintaining water quality in this ecologically sensitive river system.
