Walcz Wastewater Treatment Plant, Dzikowo, Poland

The Walcz wastewater treatment plant is located in Dzikowo, within the zachodniopomorskie province of Poland. It serves a population equivalent of 45,891, classifying it as a medium agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and its discharge ultimately contributes to the Oder River basin. As a Polish facility serving over 15,000 people, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for such agglomerations. In sensitive areas, tertiary treatment may be required to reduce nutrient loads. The plant's operational details, including specific treatment processes and capacity, are managed by the local water authority to ensure compliance with national and EU standards. The treated effluent from the plant likely discharges into local watercourses that flow into the Drawa River, a tributary of the Noteć River, which eventually joins the Warta River and then the Oder River. The Oder River discharges into the Szczecin Lagoon and the Baltic Sea. This watershed supports diverse aquatic life and is important for regional biodiversity, including migratory fish species.

The plant's discharge enters local streams that feed into the Drawa River, a tributary of the Noteć River, which flows into the Warta River and then the Oder River. The Oder River empties into the Szczecin Lagoon and the Baltic Sea. This watershed supports diverse aquatic habitats and is an important corridor for migratory fish, requiring careful nutrient management to prevent eutrophication in the Baltic Sea.
