Overview
Weiden i d Opf wastewater treatment plant serves the city of Weiden in der Oberpfalz, Bavaria, Germany. It treats wastewater for approximately 42,900 people as part of the region's municipal infrastructure.
Weiden i d Opf is a wastewater treatment plant located in Weiden in der Oberpfalz, Bavaria, Germany. The facility serves a population of approximately 42,900 residents, placing it in the medium agglomeration category 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 of this size. It is expected to meet the directive's standards for biological treatment and nutrient removal where applicable. The plant discharges treated effluent into local water bodies that eventually drain into the Danube River basin, contributing to the Black Sea watershed. Its operations help protect downstream aquatic ecosystems and maintain water quality in the region's rivers and streams.
Environmental context
The plant's treated effluent flows into the Waldnaab River, a tributary of the Naab, which joins the Danube near Regensburg. The Danube ultimately drains into the Black Sea, making this plant part of a vast transboundary watershed. The downstream environment supports diverse aquatic life, including fish species such as barbel and nase, and the river corridor serves as an important migratory route for birds. Maintaining treatment standards is critical to prevent nutrient enrichment and protect the ecological health of the Danube basin.
