MIEDZNA Wastewater Treatment Plant, Miedzna, Poland

MIEDZNA is a wastewater treatment plant located in Miedzna, within the Mazowieckie voivodeship of Poland. It serves a small population of 697 residents, reflecting its role as a local facility for this rural community. The plant is situated inland, far from coastal areas, and operates under Polish regulations aligned with the EU Urban Waste Water Treatment Directive. The plant provides secondary treatment, which is the standard level required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. With a designed capacity of 3554 m³/day and an actual discharge volume of 99.38 m³/day, the plant has ample capacity to handle current loads. The facility is part of Poland's municipal wastewater infrastructure, managed by local authorities. The treated effluent is discharged into local water bodies, contributing to the protection of the Bug River basin and ultimately the Baltic Sea. The plant plays a key role in maintaining water quality in the region, supporting aquatic ecosystems and preventing pollution in downstream environments.

The plant discharges into local streams that feed into the Bug River, a major tributary of the Narew River, which flows into the Vistula and eventually the Baltic Sea. This watershed supports diverse aquatic life and is important for migratory fish. The secondary treatment helps reduce nutrient loads, protecting downstream ecosystems from eutrophication.
