Charsznica Wastewater Treatment Plant, Miechów-Charsznica, Poland

Charsznica is a wastewater treatment plant located in the village of Witówka, within the gmina of Charsznica, powiat miechowski, in the małopolskie voivodeship of Poland. The plant serves a population of around 14,684, placing it in the medium agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). As a Polish facility, the plant operates under the national implementation of the EU UWWTD (91/271/EEC), which requires secondary treatment for agglomerations of this size. The regulatory framework ensures compliance with effluent standards to protect the local environment. The treated wastewater is discharged into the local watershed, which ultimately drains into the Vistula River basin and then to the Baltic Sea. The plant plays a key role in protecting the region's water quality, supporting aquatic life and downstream ecosystems.

The plant discharges into the local water system, part of the Vistula River basin, which flows northward to the Baltic Sea. The area is inland and agricultural, so the plant helps reduce nutrient loading that could otherwise contribute to eutrophication in the Baltic. The watershed supports diverse aquatic habitats and is important for regional biodiversity.
