COV Lomnice nad Popelkou Wastewater Treatment Plant, Lomnice nad Popelkou, Czech Republic

COV Lomnice nad Popelkou is a municipal wastewater treatment plant located in the town of Lomnice nad Popelkou, within the Semily District of the Liberecký kraj region in the Czech Republic. The plant serves a population of approximately 3,213 people, classifying it as a small agglomeration under Czech and EU regulations. As a plant serving fewer than 10,000 population equivalent (PE), it falls under the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment based on the sensitivity of the receiving waters. The plant is expected to provide secondary treatment as a minimum standard for inland freshwater discharges. The treated effluent is discharged into a local watercourse that ultimately drains into the Popelka River, a tributary of the Cidlina River, which flows into the Elbe River and eventually reaches the North Sea. The plant plays a key role in protecting the water quality of these downstream rivers and the surrounding environment.

The plant discharges into a small stream that feeds the Popelka River, part of the Elbe River basin. The Elbe flows through Germany and into the North Sea, making this plant part of a transboundary watershed. The local area includes agricultural and forested landscapes, and the receiving waters support diverse aquatic life. Proper treatment helps prevent nutrient pollution and maintains ecological balance in the downstream river system.
