Overview
Koszwaly wastewater treatment plant serves 58 people in Cedry Wielkie, Poland. It provides secondary treatment and discharges 8.27 m³/day, located within 10 km of the Baltic Sea coast.
Koszwaly wastewater treatment plant is located in Cedry Wielkie, a village in the Pomeranian Voivodeship of northern Poland. The facility serves a small population of 58 residents and operates with a designed capacity of 765.00 m³/day, though current discharge volume is 8.27 m³/day. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations under 2,000 population equivalent. For small plants like Koszwaly, secondary treatment ensures sufficient removal of organic matter and suspended solids before discharge. The plant's proximity to the Baltic Sea (within 10 km) means its treated effluent ultimately reaches the Baltic through local waterways. The Baltic Sea is a semi-enclosed brackish sea sensitive to nutrient pollution, making effective wastewater treatment crucial for protecting its ecological balance.
Environmental context
The plant discharges into local watercourses that drain into the Baltic Sea via the Vistula Delta region. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it vulnerable to eutrophication from nutrient inputs. Effective secondary treatment at Koszwaly helps reduce the load of organic pollutants and nutrients reaching this sensitive marine environment.
