Podwilk Wastewater Treatment Plant - Podwilk, Małopolskie, Poland

The Podwilk wastewater treatment plant is located in the village of Podwilk, within the gmina of Jabłonka in the nowotarski powiat of Małopolskie Voivodeship, Poland. The facility serves a population of approximately 3,537 and has a designed capacity of 3,000 cubic meters per day, with a reported discharge volume of 504.32 cubic meters per day. As a secondary treatment plant, Podwilk meets the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000 in inland areas, which aligns with the plant's treatment level and population served. The treated effluent from Podwilk is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Vistula River basin. The plant plays a key role in protecting local water quality in the mountainous region of southern Poland, supporting the ecological health of downstream rivers and the Baltic Sea ecosystem.

Podwilk is situated in the Carpathian foothills of southern Poland, within the drainage basin of the Vistula River. The treated wastewater from the plant flows into local streams that feed the Vistula, eventually reaching the Baltic Sea. The region's aquatic ecosystems support diverse species, including salmonid fish, and the plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the Baltic Sea.
