Police zaklad Wastewater Treatment Plant, Police, Zachodniopomorskie, Poland

Police zaklad is a municipal wastewater treatment plant located in Jasienica, near the town of Police in the Zachodniopomorskie region of northwestern Poland. The plant serves an estimated population of 33,082, placing it in the medium agglomeration category under EU classification. Its location near the Oder River estuary and the Baltic Sea coast makes its treatment performance environmentally significant. As a Polish facility, Police zaklad operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a facility sized for its service population. The treated effluent from Police zaklad ultimately discharges into the Oder River basin, which flows into the Szczecin Lagoon and then the Baltic Sea. This coastal region supports diverse aquatic life and is an important migratory corridor for fish species. The plant's performance directly affects the ecological health of the lagoon and Baltic coastal waters, which are subject to eutrophication pressures from nutrient loads.

Police zaklad discharges into the Oder River basin, which flows through the Szczecin Lagoon before reaching the Baltic Sea. This coastal watershed is ecologically sensitive, supporting diverse aquatic habitats and serving as a key migratory route for fish such as salmon and eel. The Baltic Sea is particularly vulnerable to nutrient pollution, making effective wastewater treatment critical for preventing eutrophication and maintaining water quality in the lagoon and coastal zone.
