Neuwied Klarwerk II - Wastewater Treatment Plant in Urmitz, Rheinland-Pfalz, Germany

Neuwied Klarwerk II is a municipal wastewater treatment plant located in Urmitz, a municipality in the district of Mayen-Koblenz, Rheinland-Pfalz, Germany. The plant serves a population of approximately 17,421, placing it in the medium agglomeration category under EU classification. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations with a population equivalent between 10,000 and 150,000. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas, such as those subject to eutrophication. The treated effluent from Neuwied Klarwerk II is discharged into the Rhine River basin, which flows through Germany and the Netherlands before reaching the North Sea. The Rhine is a major European waterway supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's operation helps protect the Rhine's water quality and downstream habitats.

The plant discharges into the Rhine River basin, which drains into the North Sea. The Rhine is a critical ecological corridor supporting migratory fish species such as salmon and eel, and its floodplains provide important habitats for birds and aquatic life. The plant's treatment processes help reduce nutrient loads that could otherwise contribute to eutrophication in the North Sea.
