The Sulmierzyce wastewater treatment plant is located in Trzęsowice, within the gmina Zawonia in the powiat trzebnicki of województwo dolnośląskie, Poland. It serves a small agglomeration of 1,599 people, reflecting its role in managing municipal wastewater for this rural community. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Although the plant's designed capacity is 6,000 cubic meters per day, the current discharge volume is 227.99 cubic meters per day, indicating ample reserve capacity.

The plant's operation helps protect downstream water quality in this ecologically important region.
Environmental context
The plant discharges into local streams that are part of the Oder River basin. The Oder flows through southwestern Poland and eventually reaches the Baltic Sea, supporting diverse aquatic life and serving as a migratory corridor for fish. The region's watershed is ecologically sensitive, and the plant's secondary treatment helps reduce nutrient and organic loads, mitigating eutrophication risks in downstream waters.
