Overview
Komunalna Oczyszczalnia Sciekow w Chociwlu is a secondary treatment plant serving about 3,100 people in Chociwel, Poland. It discharges treated wastewater into local water bodies in the zachodniopomorskie region.
Komunalna Oczyszczalnia Sciekow w Chociwlu is a municipal wastewater treatment plant located in Chociwel, a town in the zachodniopomorskie province of northwestern Poland. The plant serves a population of approximately 3,100, classifying it as a small agglomeration under Polish and EU regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater bodies from agglomerations of this size. With a designed capacity of 3,381 m³/day and an average daily discharge volume of 447 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local surface waters that eventually drain into the Baltic Sea via the Odra River basin. The plant plays a key role in protecting the region's water quality, supporting aquatic ecosystems and downstream communities. Its location inland, more than 10 km from the coast, reduces direct marine impact but still contributes to the overall health of the Baltic catchment.
Environmental context
The plant discharges into local streams that feed into the Ina River, a tributary of the Odra River, which flows into the Szczecin Lagoon and ultimately the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea sensitive to nutrient pollution, making effective wastewater treatment critical. The plant's secondary treatment helps reduce organic load and nutrients, supporting the ecological health of the downstream water bodies and mitigating eutrophication risks.
