Myczkowce Wastewater Treatment Plant, Uherce Mineralne, Poland

Myczkowce is a wastewater treatment plant located in Uherce Mineralne, within the podkarpackie province of Poland. It serves a small population of 81 residents, reflecting its role in a rural community. The plant is situated near the medieval settlement of Grodzisko, in the scenic region of the Bieszczady Mountains. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 200 m³/day and an actual discharge volume of 11.55 m³/day, the facility operates well below its capacity, indicating room for future growth. As a Polish plant serving fewer than 2,000 people, it falls under national regulations that align with the EU Urban Waste Water Treatment Directive, which requires appropriate treatment for small agglomerations. The treated effluent is discharged into the local watershed, which ultimately drains into the San River, a tributary of the Vistula River. The Vistula flows into the Baltic Sea, making this plant part of a larger transboundary water system. The surrounding area is ecologically sensitive, supporting diverse aquatic life and serving as a habitat for species in the Carpathian region.

The plant discharges into the San River basin, which flows into the Vistula River and eventually reaches the Baltic Sea. This watershed supports diverse aquatic ecosystems, including fish species such as brown trout and grayling. The region's mountainous terrain and forested catchments contribute to high water quality, making effective wastewater treatment critical for preserving downstream habitats.
