Overview
Granice wastewater treatment plant serves the Różanów area in województwo mazowieckie, Poland. It treats wastewater for approximately 25,390 people under EU regulatory standards.
Granice is a wastewater treatment plant located in Różanów, within the gmina Wiskitki, powiat żyrardowski, województwo mazowieckie, Poland. The facility serves a population of about 25,390, placing it in the medium agglomeration category under Polish and EU classifications. As a Polish plant, Granice operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. 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 national and EU water quality objectives. The treated effluent from Granice is discharged into local watercourses that ultimately drain into the Vistula River basin, which flows northward into the Baltic Sea. The plant plays a key role in protecting the region's surface waters from nutrient pollution, supporting aquatic ecosystems and downstream water quality in the Vistula and the Baltic Sea.
Environmental context
The plant discharges into the Vistula River basin, which drains into the Baltic Sea. The region's waters support diverse aquatic life and are important for migratory fish species. Nutrient removal is critical to prevent eutrophication in the Baltic Sea, a semi-enclosed sea sensitive to nitrogen and phosphorus loads.
Frequently asked questions
Granice is located in Różanów, within the gmina Wiskitki, powiat żyrardowski, województwo mazowieckie, Poland.
The plant serves approximately 25,390 people, classifying it as a medium-sized agglomeration under EU standards.
The treated effluent is discharged into local watercourses that are part of the Vistula River basin, which flows into the Baltic Sea.
Under the EU Urban Waste Water Treatment Directive 91/271/EEC, plants serving agglomerations of this size must provide secondary treatment. If the receiving waters are sensitive, tertiary treatment for nutrient removal may be required.
In Poland, plants of this scale typically employ secondary biological treatment, often with nutrient removal to meet EU standards, especially when discharging into sensitive areas like the Baltic Sea catchment.
