Brzeziny Wastewater Treatment Plant, Morawica, Poland

The Brzeziny wastewater treatment plant is located in Morawica, within the świętokrzyskie province of Poland. It serves a population of 4,275, classifying it as a small agglomeration under Polish and EU regulations. The plant operates with advanced treatment, ensuring high-quality effluent before discharge. As an advanced treatment facility, Brzeziny goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants discharging into sensitive areas. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are generally required to provide secondary treatment, but advanced treatment may be mandated if the receiving waters are sensitive to eutrophication. The plant discharges 609.55 cubic meters of treated wastewater per day. The plant is located inland, and its effluent likely flows into a local river or stream that eventually drains into the Vistula River basin and then into the Baltic Sea. The advanced treatment helps protect downstream aquatic ecosystems from nutrient pollution.

The Brzeziny plant is situated inland in the świętokrzyskie region, within the Vistula River basin. Treated effluent likely enters a local tributary that flows into the Vistula, which ultimately reaches the Baltic Sea. The advanced treatment process reduces nutrient loads, helping to prevent eutrophication in downstream waters and supporting the ecological health of the Baltic Sea, which is sensitive to nitrogen and phosphorus pollution.
