COV Pecky Wastewater Treatment Plant, Pečky, Central Bohemia

COV Pecky is a municipal wastewater treatment plant located in Pečky, a town in the Central Bohemian Region of the Czech Republic. The plant serves a population of approximately 4,731 people, classifying it as a small to medium agglomeration under Czech and EU standards. It is situated in the Elbe River basin, which drains into the North Sea. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size discharging into freshwater. The design capacity of 7,000 m³/day indicates the plant is sized to handle current and future flows, with a reported discharge volume of 673.71 m³/day suggesting operational headroom. Treated effluent from COV Pecky is discharged into local watercourses that ultimately flow into the Elbe River. The Elbe is a major Central European river that supports diverse aquatic ecosystems and provides drinking water for millions. The plant's secondary treatment helps protect water quality in the Elbe basin by reducing organic pollutants and suspended solids before discharge.

COV Pecky discharges into the Elbe River basin, which drains through Germany into the North Sea. The Elbe supports important fish populations, including migratory species such as salmon and eel. The plant's secondary treatment helps maintain water quality in this ecologically sensitive river system, which is also used for recreation and agriculture downstream.
