Niepruszewo Wastewater Treatment Plant, Podłoziny, Poland

The Nieprzewo wastewater treatment plant is located in Podłoziny, within the gmina Dopiewo in powiat poznański, województwo wielkopolskie, Poland. It serves a population of 1,873, classifying it as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 2,480 m³/day, and the current discharge volume is 267.06 m³/day, indicating operational capacity well within design limits. The treated effluent is discharged into the local watershed, which ultimately drains into the Warta River basin and then to the Oder River, flowing into the Baltic Sea. The plant plays a role in protecting the region's surface water quality and supporting the ecological health of the downstream aquatic environment.

The plant discharges into the local water system, which is part of the Warta River basin, a major tributary of the Oder River. The Oder flows into the Szczecin Lagoon and then the Baltic Sea. This watershed supports diverse aquatic life and is important for migratory fish species. The plant's secondary treatment helps reduce organic pollution and nutrient loads, contributing to the protection of downstream water bodies.
