Glowczyce Wastewater Treatment Plant, Skórzyno, Poland - Coastal Secondary Treatment

Glowczyce is a wastewater treatment plant located in Skórzyno, a village in the Główczyce commune of northern Poland. The facility serves a small population of 268 people, reflecting its role in a rural coastal community. The plant is situated within 10 kilometers of the Baltic Sea coast, placing it in a sensitive coastal zone. The plant provides secondary treatment, which is the standard biological treatment required under Polish regulations implementing the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations with a population equivalent under 2,000, the directive allows appropriate treatment, and secondary treatment exceeds the minimum requirement. The plant's designed capacity is 5,832 cubic meters per day, with a reported discharge volume of 38.21 cubic meters per day. Treated effluent from the plant ultimately drains into the Baltic Sea, a semi-enclosed sea with limited water exchange and high ecological sensitivity. The coastal waters support diverse marine life and are important for fisheries and tourism. The plant's operation helps protect the Baltic Sea from nutrient pollution, which can cause eutrophication and algal blooms.

The plant discharges into local watercourses that flow to the Baltic Sea, a brackish sea with unique ecological conditions. The Baltic Sea is highly sensitive to nutrient inputs, and secondary treatment helps reduce organic load and nutrients. The coastal zone supports habitats for fish, birds, and aquatic plants, making proper wastewater treatment critical for maintaining water quality and biodiversity.
