Golina Wastewater Treatment Plant - Wielkopolskie, Poland

The Golina wastewater treatment plant is located in the town of Golina, within the powiat koniński of województwo wielkopolskie, Poland. It serves a population of approximately 3,672 residents, classifying it as a small agglomeration under Polish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are integral to the local sanitation infrastructure. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,100 cubic meters per day and an average discharge volume of 523.57 cubic meters per day, the facility operates well within its capacity. The treatment process ensures that effluent meets regulatory standards before discharge. The treated wastewater from Golina is discharged into local watercourses that ultimately drain into the Warta River, a major tributary of the Oder River, which flows into the Baltic Sea. The plant plays a crucial role in protecting the Warta basin from nutrient pollution and maintaining water quality for downstream ecosystems and communities.

The Golina plant discharges into the Warta River basin, which flows through western Poland and joins the Oder River before reaching the Baltic Sea. The Warta River supports diverse aquatic life and is an important ecological corridor. The plant's secondary treatment helps reduce organic load and nutrient inputs, mitigating eutrophication risks in downstream waters. The region's agricultural land use makes nutrient management particularly important for protecting the Baltic Sea from excessive nitrogen and phosphorus.
