The Janowice Wielkie wastewater treatment plant is located in the town of Janowice Wielkie, within the powiat karkonoski of województwo dolnośląskie, Poland. Serving a population of approximately 41,000, the plant is a key component of the region's municipal wastewater infrastructure, handling domestic and industrial flows from the local community. As a Polish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment for agglomerations with a population equivalent (PE) between 10,000 and 150,000. For sensitive areas, more stringent tertiary treatment may be mandated. The plant's design and operation are subject to Polish national regulations that transpose the directive, ensuring compliance with European water quality standards. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Baltic Sea via the Oder River basin. The region's aquatic ecosystems benefit from the plant's pollution control, which helps maintain water quality in downstream rivers and supports biodiversity in the broader catchment area.
Environmental context
The plant discharges into local streams that are part of the Oder River basin, which flows northward into the Baltic Sea. The surrounding area features the Karkonosze Mountains, a ecologically sensitive region with diverse aquatic habitats. Effective wastewater treatment is crucial to protect these water bodies from nutrient pollution and to preserve the ecological integrity of the downstream environment.
