Oczyszczalnia Brzeziny - Wastewater Treatment Plant in Rawicz, Poland

Oczyszczalnia Brzeziny is a municipal wastewater treatment plant located in Rawicz, within the gmina Drużbice of powiat bełchatowski, województwo łódzkie, Poland. The facility serves a population of approximately 17,500 people, classifying it as a medium-sized agglomeration under EU classification. As a Polish plant, it operates under national regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires at least secondary treatment, with more stringent standards if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with EU standards. The treated effluent is discharged into local watercourses that eventually drain into the Vistula River basin, which flows into the Baltic Sea. The plant plays a key role in protecting the region's water quality, supporting aquatic ecosystems and downstream communities.

The plant discharges into local streams that are part of the broader Vistula River basin, ultimately reaching the Baltic Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. The area's inland location means the effluent contributes to freshwater systems that require careful management to prevent nutrient enrichment and maintain ecological balance.
