Lwówek Śląski Wastewater Treatment Plant - Serving Lwówek Śląski, Lower Silesia, Poland

The Lwówek Śląski wastewater treatment plant is located in the town of Lwówek Śląski, in the Lower Silesian Voivodeship of southwestern Poland. Serving a population of about 14,300, the plant is a key component of the region's municipal wastewater infrastructure, handling domestic sewage from the town and surrounding areas. 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 (between 10,000 and 15,000 population equivalent). The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes are designed to meet these regulatory standards, ensuring compliance with Polish and European environmental law. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Oder River basin, which flows northward to the Baltic Sea. The plant plays a vital role in protecting the water quality of the region's rivers and the downstream Baltic ecosystem from nutrient pollution and other contaminants.

The plant discharges into the Bóbr River, a tributary of the Oder River, which flows through western Poland and into the Baltic Sea via the Szczecin Lagoon. The Bóbr River supports diverse aquatic life and is an important corridor for migratory fish. The plant's operations help maintain water quality in this ecologically sensitive river system, reducing nutrient loads that could contribute to eutrophication in the Baltic Sea.
