Nowy Dwor Gdanski Wastewater Treatment Plant - Nowy Dwór Gdański, Poland

The Nowy Dwor Gdanski wastewater treatment plant is located in Nowy Dwór Gdański, a town in the Pomeranian Voivodeship of northern Poland. The facility serves a population of approximately 10,314 people, classifying it as a medium-sized agglomeration under Polish and EU regulations. The plant is situated near the Vistula Delta, a ecologically sensitive area that drains into the Baltic Sea. As a Polish wastewater facility serving a population over 10,000, the plant is required to meet secondary treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive mandates that agglomerations of this size provide at least secondary biological treatment to reduce organic pollutants and nutrients. The plant's design capacity of 1.00 cubic meters per hour suggests it is sized appropriately for its service population. The treated effluent from the plant is discharged into local waterways that are part of the Vistula River basin, ultimately flowing into the Baltic Sea via the Vistula Lagoon. This region supports diverse aquatic life and is an important migratory corridor for birds. The plant plays a critical role in protecting the sensitive coastal and lagoon ecosystems from nutrient pollution and pathogens.

The plant discharges into the Vistula River basin, which flows through the Vistula Delta and into the Vistula Lagoon, a coastal lagoon on the Baltic Sea. This area is ecologically sensitive, supporting diverse aquatic habitats and serving as a key stopover for migratory waterbirds. Nutrient loading from wastewater can contribute to eutrophication in the Baltic Sea, making effective treatment essential for regional water quality.
