Overview
Jelenia Gora wastewater treatment plant serves approximately 99,448 people in Jelenia Góra, Poland. The facility operates under EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates secondary treatment for agglomerations of this scale.
The Jelenia Gora wastewater treatment plant is located in Jelenia Góra, in the Lower Silesian Voivodeship of southwestern Poland. It serves a population of approximately 99,448 people, classifying it as a medium-to-large agglomeration under EU regulations. The plant is situated near the Bóbr River, a tributary of the Oder River, which ultimately drains into the Baltic Sea. As a Polish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC. For agglomerations with a population equivalent (PE) between 10,000 and 150,000, the directive requires secondary treatment (biological treatment) as a minimum standard. In sensitive areas, such as those draining into the Baltic Sea, tertiary treatment (nutrient removal) may be required to reduce eutrophication. It is expected to meet these regulatory standards. The treated effluent from the plant is discharged into the local water system, likely the Bóbr River, which flows northward to join the Oder River near Krosno Odrzańskie. The Oder River then continues to the Baltic Sea via the Szczecin Lagoon. This water body chain is ecologically significant, supporting diverse aquatic life and serving as a migratory corridor for fish species. The Baltic Sea is a sensitive marine environment prone to eutrophication, making nutrient removal at upstream treatment plants critical for its health.
Environmental context
The Jelenia Gora plant discharges into the Bóbr River, a tributary of the Oder River, which flows into the Baltic Sea via the Szczecin Lagoon. This watershed is ecologically sensitive, supporting diverse aquatic habitats and serving as an important migratory corridor for fish. The Baltic Sea is a semi-enclosed sea with limited water exchange, making it vulnerable to nutrient pollution and eutrophication from upstream sources.
Frequently asked questions
The plant is located in Jelenia Góra, in the Lower Silesian Voivodeship of southwestern Poland, near the Bóbr River.
The plant serves approximately 99,448 people, classifying it as a medium-to-large agglomeration under EU regulations.
Treated effluent is discharged into the local water system, likely the Bóbr River, which flows into the Oder River and ultimately reaches the Baltic Sea.
As a Polish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size and tertiary treatment in sensitive areas.
For agglomerations with a population equivalent of 10,000 to 150,000, the EU directive mandates secondary treatment. In sensitive areas like the Baltic Sea basin, tertiary treatment for nutrient removal is often required to prevent eutrophication.
