Overview
Kruszwica wastewater treatment plant serves approximately 37,000 people in Lachmirowice, Poland. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Kruszwica wastewater treatment plant is located in Lachmirowice, within the Kruszwica municipality in the kujawsko-pomorskie province of Poland. It serves a population of approximately 37,000 people, classifying it as a medium-sized agglomeration under EU regulations. As a Polish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant discharges treated wastewater into local water bodies that ultimately drain into the Vistula River basin, which flows into the Baltic Sea. The surrounding region is agricultural, with the plant playing a key role in protecting local surface water quality and the downstream aquatic environment.
Environmental context
The Kruszwica plant discharges into the local watershed, which is part of the Vistula River basin. The Vistula flows northward through Poland and empties into the Baltic Sea via the Gdańsk Bay. The region supports diverse aquatic life and is an important ecological corridor for migratory fish species. The Baltic Sea is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution from wastewater discharges.
