Untere Nims GKA Messerich - Advanced Wastewater Treatment in Dockendorf, Germany

Untere Nims GKA Messerich is an advanced wastewater treatment plant located in Dockendorf, in the Eifelkreis Bitburg-Prüm district of Rhineland-Palatinate, Germany. The plant serves a population of approximately 2,910 people and has a designed capacity of 3,045 cubic meters per day, with an average discharge volume of 925.74 cubic meters per day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants in sensitive catchment areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires tertiary treatment for agglomerations above 10,000 population equivalent discharging into sensitive areas, but smaller plants may also adopt advanced treatment to protect local water quality. The plant discharges treated wastewater into the local watershed, which drains into the Nims River, a tributary of the Prüm, which flows into the Sauer River and eventually the Moselle and Rhine rivers. The Rhine basin is a major European waterway supporting diverse aquatic life and providing drinking water for millions. Advanced treatment helps minimize nutrient loading and protects downstream ecosystems.

The plant discharges into the Nims River, a tributary of the Prüm, which flows into the Sauer River and then the Moselle and Rhine rivers. The Rhine basin is a critical European waterway that supports diverse aquatic species and provides drinking water for millions. Advanced treatment at this plant helps reduce nutrient pollution, protecting downstream habitats and water quality in the Rhine delta.
