Overview
Trzcinsko zdroj is a secondary treatment plant serving Trzcińsko-Zdrój, Poland. It discharges 310.26 m³/day of treated wastewater, with a designed capacity of 3,800 m³/day.
The Trzcinsko zdroj wastewater treatment plant serves the town of Trzcińsko-Zdrój in the West Pomeranian Voivodeship of northwestern Poland. With a population equivalent of approximately 2,176, it is classified as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater bodies. The designed capacity of 3,800 m³/day indicates the plant has headroom for future growth or seasonal peaks. Current discharge volume is 310.26 m³/day, well below capacity. Treated effluent is discharged into a local watercourse that ultimately drains into the Oder River basin and then the Baltic Sea. The plant plays a key role in protecting the region's surface waters from nutrient pollution, supporting aquatic life and downstream ecosystems in the sensitive Baltic Sea catchment.
Environmental context
The plant discharges into a tributary of the Oder River, which flows into the Szczecin Lagoon and then the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea highly sensitive to eutrophication from nutrient inputs. Secondary treatment helps reduce organic load and nutrients, but further nutrient removal may be needed to meet Baltic Sea Action Plan targets. The local watershed supports diverse aquatic habitats and migratory fish species.
