Chodorowa Wastewater Treatment Plant, Wojnarowa, Poland

Chodorowa wastewater treatment plant is located in the village of Wojnarowa, within the gmina of Korzenna in the małopolskie province of Poland. The facility was designed to serve the local population with a capacity of 1500 cubic meters per day, reflecting a small-scale municipal plant typical of rural areas in southern Poland. The plant is now closed and no longer operational. As a secondary treatment plant, Chodorowa would have met the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary biological treatment for agglomerations of this size. Polish regulations transpose this directive, requiring such plants to reduce organic matter and suspended solids before discharge. The area drains into the Dunajec River basin, a tributary of the Vistula River, which flows into the Baltic Sea. The region is part of the Carpathian foothills, with sensitive aquatic ecosystems that benefit from proper wastewater treatment. The plant's operation would have helped protect local streams and the downstream Vistula from nutrient pollution.

Chodorowa plant is situated in the Dunajec River basin, which flows into the Vistula River and ultimately the Baltic Sea. The area features small streams and groundwater that support diverse aquatic life. Proper treatment is essential to prevent eutrophication in the Baltic Sea, a sensitive marine environment. The plant's secondary treatment would have reduced organic load and nutrients, contributing to the health of the local watershed.
