Overview
Cedry Wielkie wastewater treatment plant in Poland serves 3,208 people with secondary treatment. Located near the Baltic coast, it discharges 457.41 m³/day and has a designed capacity of 4,200 m³/day.
Cedry Wielkie wastewater treatment plant is located in the village of Cedry Wielkie, within the Pomeranian Voivodeship of northern Poland. The facility serves a population of 3,208 and is situated in the Żuławy Wiślane region, a low-lying delta area near the Baltic Sea coast. The plant provides secondary treatment, meeting the standard requirements under Polish regulations which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations between 2,000 and 10,000 population equivalent, secondary treatment is the baseline requirement. The plant's designed capacity of 4,200 m³/day indicates it can handle additional load during peak conditions. Treated effluent is discharged into local watercourses that ultimately drain into the Baltic Sea via the Vistula River delta. The Baltic Sea is a sensitive marine environment with eutrophication challenges, making nutrient removal important for plants in this coastal region. The facility contributes to protecting the local watershed and downstream coastal waters.
Environmental context
The plant discharges into the local drainage network of the Vistula River delta, which flows into the Gdańsk Bay of the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with limited water exchange, making it highly sensitive to nutrient pollution. The surrounding Żuławy region is a flat, agricultural area with an extensive canal system, where wastewater treatment helps prevent eutrophication in downstream coastal ecosystems.
