COV Touzim Wastewater Treatment Plant, Chodová Planá, Czech Republic

COV Touzim is a wastewater treatment plant located in Chodová Planá, within the Plzeňský kraj region of the Czech Republic. The plant serves a population of approximately 2,686 people, classifying it as a small agglomeration under Czech and EU regulations. Its location near the town of Touzim places it in a rural to semi-urban setting in western Bohemia. As a plant serving fewer than 10,000 population equivalent, COV Touzim 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 effluent standards. The plant's designed capacity is not disclosed, but its current population served suggests a modest infrastructure footprint. The treated effluent from COV Touzim likely discharges into a local stream or river that feeds into the Mže River basin, which ultimately drains into the Berounka River and then the Vltava River, a major tributary of the Elbe River. The Elbe flows through Germany into the North Sea, making this plant part of a transboundary water system. The surrounding region includes agricultural areas and small settlements, and the plant plays a role in protecting local water quality.

The plant's discharge enters the Mže River basin, which flows into the Berounka River, then the Vltava, and finally the Elbe River before reaching the North Sea. This watershed supports diverse aquatic life and is an important corridor for migratory fish. The plant's operations help maintain water quality in a region that includes both agricultural runoff and small urban centers, reducing nutrient loads that could otherwise contribute to downstream eutrophication.
