Zazdzierz Wastewater Treatment Plant, Górki, Mazowieckie, Poland

The Zazdzierz wastewater treatment plant is located in Górki, within the Gąbin commune in Mazowieckie Voivodeship, Poland. This facility, now closed, was designed to serve the local community with a capacity of 2,143 cubic meters per day. Its advanced treatment level indicates it was equipped to remove nutrients and other pollutants beyond secondary standards. Although the plant is no longer operational, its design reflects Poland's alignment with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. The Mazowieckie region includes parts of the Vistula basin, where nutrient removal is critical to protect the Baltic Sea from eutrophication. The plant's receiving waters likely drain into the Vistula River, which flows northward into the Baltic Sea. The Baltic Sea is a semi-enclosed sea highly sensitive to nutrient pollution, making advanced treatment essential for plants in this watershed.

The plant is situated in the Vistula River basin, which drains into the Baltic Sea via the Gulf of Gdańsk. The Baltic Sea is a brackish water body with limited water exchange, making it highly vulnerable to eutrophication from nutrient inputs. Advanced treatment at this plant would have helped reduce nitrogen and phosphorus loads, supporting the health of downstream aquatic ecosystems and coastal waters.
