Overview
COV Semily is a municipal wastewater treatment plant serving Semily in the Liberecký kraj region of the Czech Republic. It treats wastewater for approximately 6,339 residents.
COV Semily is a municipal wastewater treatment plant located in Semily, within the Liberecký kraj region of the Czech Republic. The plant serves a population of approximately 6,339 residents, classifying it as a small to medium agglomeration under Czech and EU regulatory frameworks. As a plant serving fewer than 10,000 people, COV Semily is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on the sensitivity of the receiving waters. Plants of this scale typically employ secondary biological treatment to meet regulatory standards. The plant discharges treated effluent into the local watershed, which ultimately drains into the Jizera River, a tributary of the Elbe River. The Elbe flows through Germany and into the North Sea, making the plant's operations relevant to downstream water quality in both the Czech Republic and Germany.
Environmental context
COV Semily discharges into the Jizera River basin, which flows into the Elbe River and eventually reaches the North Sea. The Jizera River supports diverse aquatic life and is an important ecological corridor in the region. The plant's location in a river valley near the Krkonoše Mountains means its effluent can affect sensitive downstream habitats, including those supporting fish species such as brown trout and grayling.
