Oczyszczalnia Sciekow Cisewie - Secondary Wastewater Treatment Plant in Cisewie, Poland

Oczyszczalnia Sciekow Cisewie is a municipal wastewater treatment plant located in Cisewie, a village in the Pomeranian Voivodeship of northern Poland. The plant serves a small population of 537 residents, reflecting its role in a rural community. Its designed capacity is 4950 m³/day, indicating it can handle higher flows during peak periods. The plant provides secondary treatment, which is the standard biological treatment required under Polish regulations aligned with the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations under 2000 population equivalent, the directive mandates appropriate treatment, and secondary treatment meets this requirement. The plant operates under permits issued by the Polish water authority, ensuring compliance with national and EU standards. The treated effluent is discharged into local surface waters, likely tributaries of the Wda River, which flows into the Vistula River and eventually the Baltic Sea. This small plant plays a key role in protecting the local aquatic ecosystem and downstream water quality in the Baltic Sea catchment.

The plant discharges into a small watercourse that drains into the Wda River, a tributary of the Vistula River. The Vistula flows northward into the Baltic Sea, a semi-enclosed sea sensitive to nutrient pollution. The local watershed supports diverse aquatic life and is part of a region with valuable natural habitats. Proper treatment at this plant helps reduce nutrient loads and protects downstream ecosystems.
