Kreuztal Wastewater Treatment Plant: Serving Kreuztal, Nordrhein-Westfalen, Germany

The Kreuztal wastewater treatment plant is located in the town of Kreuztal, in the Siegen-Wittgenstein district of Nordrhein-Westfalen, Germany. It serves a population of approximately 93,500 people, classifying it as a large agglomeration under EU regulations. The plant is situated in the Hüttentalstraße area, near the Buschhütten and Fellinghausen districts. As a German wastewater facility serving over 50,000 people, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for all discharges from agglomerations of this size, with more stringent tertiary treatment if the receiving waters are designated as sensitive areas. The plant's treatment process and capacity details are not publicly available, but the regulatory framework ensures a minimum level of treatment. The treated effluent from the Kreuztal plant is discharged into local watercourses that eventually flow into the Sieg River, a tributary of the Rhine. The Rhine basin is one of Europe's most important river systems, supporting diverse aquatic life and providing water for millions of people. The plant plays a key role in protecting the water quality of these downstream environments.

The Kreuztal plant discharges into the local watershed, which drains into the Sieg River and ultimately the Rhine River. The Rhine basin is a major European waterway that supports diverse aquatic ecosystems, including migratory fish species such as salmon and eel. The plant's treatment level helps protect these downstream habitats from nutrient pollution and other contaminants.
