Overview
Trzyciaz wastewater treatment plant in Trzyciąż, Poland, serves 563 people with secondary treatment. It discharges 80.28 m³/day and has a designed capacity of 1830 m³/day.
The Trzyciaz wastewater treatment plant is located in Trzyciąż, a village in the małopolskie province of southern Poland. It serves a small population of 563 residents, reflecting the rural character of the area. The plant is part of Poland's municipal wastewater infrastructure, which is regulated under the EU Urban Waste Water Treatment Directive (UWWTD). The plant provides secondary treatment, which is the standard required by the UWWTD for agglomerations of this size. It has a designed capacity of 1830 m³/day and currently discharges 80.28 m³/day of treated effluent. The treatment process and specific operational details are managed by local municipal authorities. The treated wastewater is discharged into local watercourses that drain into the broader Vistula River basin. The Vistula flows northward through Poland and eventually reaches the Baltic Sea. The plant's operations help protect the region's surface water quality and support the ecological health of downstream aquatic habitats.
Environmental context
The plant's effluent enters small streams in the Prądnik River catchment, part of the upper Vistula basin. The Vistula River is the longest river in Poland and flows into the Baltic Sea via the Gdańsk Bay. The region supports diverse aquatic life, including fish species such as barbel and chub, and the plant's secondary treatment reduces organic pollutants and nutrients that could otherwise contribute to eutrophication in downstream waters.
