COV Nyrsko Wastewater Treatment Plant, Nýrsko, Plzeňský kraj

COV Nyrsko is a municipal wastewater treatment plant located in Nýrsko, a town in the Plzeňský kraj region of the Czech Republic. The facility serves a population of approximately 3,620 residents, classifying it as a small agglomeration under EU regulations. The plant is situated near the Bystřice nad Úhlavou stream, a tributary of the Úhlava River. As a Czech plant serving fewer than 10,000 people, COV Nyrsko operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into freshwater. It is expected to meet national standards set by the Czech Ministry of Agriculture and the Water Act. The treated effluent from COV Nyrsko is discharged into the Úhlava River, which flows into the Radbuza River, then the Berounka, and ultimately the Vltava River, a major tributary of the Elbe River. The Elbe drains into the North Sea. The Úhlava River supports diverse aquatic life and is part of a network of streams in the Šumava foothills, contributing to the ecological health of the region.

COV Nyrsko discharges into the Bystřice nad Úhlavou stream, a tributary of the Úhlava River. The Úhlava flows through the Plzeňský kraj region and joins the Radbuza River, which later merges with the Berounka and Vltava Rivers, ultimately reaching the Elbe River and the North Sea. The local watershed is ecologically sensitive, supporting fish populations and riparian habitats in the Šumava foothills. The plant's operations help protect water quality in this river system, which is important for both biodiversity and downstream water uses.
