Wernberg Koblitz Wastewater Treatment Plant, Wernberg, Bavaria

The Wernberg Koblitz wastewater treatment plant is located in Wernberg, a town in the Bavarian district of Schwandorf, Germany. The facility serves a population of approximately 11,000 residents, classifying it as a medium-sized agglomeration under European Union regulations. As a German plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent between 2,000 and 15,000. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant discharges treated wastewater into a local watercourse that ultimately drains into the Naab River, a tributary of the Danube. The Danube basin supports diverse aquatic life and is an important ecological corridor in Central Europe. The plant's location inland and away from coastal areas reduces direct marine impact.

The treated effluent from Wernberg Koblitz flows into a small stream that joins the Naab River, which then feeds into the Danube River system. The Danube basin is a major European watershed supporting diverse fish species and migratory birds. The plant's inland location means its discharge contributes to freshwater ecosystems rather than coastal or marine environments.
