Overview
Marl Lenkerbeck wastewater treatment plant serves approximately 25,000 people in Marl, Nordrhein-Westfalen, Germany. It operates under the EU Urban Waste Water Treatment Directive.
Marl Lenkerbeck is a municipal wastewater treatment plant located in the Hüls-Nord district of Marl, in the state of Nordrhein-Westfalen, Germany. The facility serves a population of approximately 25,216, placing it in the medium agglomeration category under EU classification. As a German plant of this scale, it is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalents. The plant's treatment processes are designed to meet national standards under the German Water Resources Act (Wasserhaushaltsgesetz). The plant discharges treated effluent into the local watershed, which ultimately drains into the Lippe River, a tributary of the Rhine. The Rhine basin supports diverse aquatic ecosystems and is a major European waterway. The plant plays a key role in protecting water quality in this densely populated and industrialized region.
