Oczyszczalnia dla Miasta Darlowo - Wastewater Treatment Plant in Żukowo Morskie, Poland

Oczyszczalnia dla Miasta Darlowo is a wastewater treatment plant located in Żukowo Morskie, within the gmina Darłowo in the West Pomeranian Voivodeship of Poland. The plant serves a population of approximately 79,014, placing it in the category of a medium-to-large agglomeration under Polish and EU regulations. Its designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating a facility sized to handle the region's wastewater needs. As a Polish plant serving over 15,000 population equivalent, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For agglomerations of this scale, the directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. It is subject to Polish national regulations that transpose EU requirements. The plant is situated within 50 km of the Baltic Sea coast, making its discharge potentially influential on coastal water quality. The treated effluent likely flows into local rivers or directly into the Baltic Sea via the Wieprza River or other watercourses in the region. The Baltic Sea is a sensitive marine environment with eutrophication challenges, so nutrient removal is a key concern for plants in this coastal zone.

The plant's discharge ultimately reaches the Baltic Sea, a semi-enclosed sea with limited water exchange, making it vulnerable to nutrient pollution. The local watershed includes the Wieprza River and other coastal streams that drain into the southern Baltic. This area supports diverse aquatic life and is an important migratory corridor for fish. Protecting water quality here is critical for both local ecosystems and the broader Baltic marine environment.
