Overview
Kamien Krajenski wastewater treatment plant serves the town of Kamień Krajeński in kujawsko-pomorskie, Poland. It provides secondary treatment for a population of 2,987, discharging 425.90 m³/day.
The Kamien Krajenski wastewater treatment plant is located in Kamień Krajeński, a town in the kujawsko-pomorskie region of northern Poland. The facility serves a population of approximately 2,987, making it a small agglomeration under Polish and EU classifications. The plant provides secondary biological treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,675 m³/day and a current discharge volume of 425.90 m³/day, the plant operates well below its capacity, indicating room for future growth. The treated effluent is discharged into local watercourses that eventually drain into the Baltic Sea via the Vistula River basin. The plant plays a key role in protecting the region's surface waters from nutrient pollution, supporting aquatic life and downstream ecosystems.
Environmental context
The plant discharges into local streams that are part of the Vistula River basin, which flows northward into the Baltic Sea. The Baltic Sea is a semi-enclosed sea sensitive to eutrophication from nutrient inputs, making effective wastewater treatment critical. The secondary treatment provided helps reduce organic load and nutrients, contributing to the health of downstream aquatic habitats.
