Leka Wastewater Treatment Plant, Łęka, Poland - Closed Secondary Facility

Leka wastewater treatment plant is located in Łęka, a village in the gmina Korzenna, powiat nowosądecki, województwo małopolskie, Poland. The plant was designed to serve the local population with a capacity of 3700 m³/day, but it is currently closed and no longer operational. As a secondary treatment facility, the plant would have provided biological treatment to reduce organic matter and suspended solids. In Poland, wastewater treatment plants are regulated under national law transposing the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment based on agglomeration size. For smaller communities, secondary treatment is typically required. The area drains into the Dunajec River basin, a tributary of the Vistula River, which flows into the Baltic Sea.

The plant is located in the Dunajec River basin, part of the larger Vistula River catchment that drains into the Baltic Sea. The Dunajec River supports diverse aquatic life and is an important ecological corridor in southern Poland. The closure of the plant may reduce local discharge impacts, but alternative wastewater management must ensure continued protection of downstream water quality.
