COV Kryry Wastewater Treatment Plant, Kryry, Ústecký kraj

COV Kryry is a municipal wastewater treatment plant located in the town of Kryry in the Ústecký kraj region of the Czech Republic. The facility serves a small population of approximately 827 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to reduce organic pollutants before discharge. The plant operates under the Czech Republic's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. With a designed capacity of 7,204 m³/day and an actual discharge volume of 360.43 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately flow into the Ohře River, a tributary of the Elbe River. The Elbe drains into the North Sea, making this plant part of a transboundary river basin. The surrounding area is predominantly agricultural, and the plant helps protect downstream water quality and aquatic ecosystems.

COV Kryry discharges into small streams that feed the Ohře River, which flows into the Elbe River and eventually reaches the North Sea. The local watershed supports diverse aquatic life and is important for regional biodiversity. The plant's secondary treatment reduces organic load and nutrients, helping to prevent eutrophication in downstream water bodies.
