NIEMCE Wastewater Treatment Plant, Radawiec Duży, Lublin Voivodeship

NIEMCE is a wastewater treatment plant located in Radawiec Duży, within the gmina Konopnica, powiat lubelski, in the Lublin Voivodeship of eastern Poland. The plant serves a population of 2,317 and operates with secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 7,800 m³/day and currently discharges 330.37 m³/day of treated wastewater. As a Polish facility, it operates under national regulations that transpose EU directives, with permits issued by the Regional Water Management Board (RZGW) in Lublin. Secondary treatment ensures removal of organic matter and suspended solids, meeting EU standards for inland waters. The treated effluent is discharged into local watercourses that drain into the Bystrzyca River, a tributary of the Wieprz River, which ultimately flows into the Vistula River and then the Baltic Sea. The plant plays a key role in protecting the local watershed and downstream ecosystems from nutrient pollution.

The plant discharges into local streams that feed the Bystrzyca River, part of the Vistula basin. The Vistula River flows into the Baltic Sea, a semi-enclosed sea sensitive to eutrophication from nutrient loads. The surrounding Lublin region is agricultural, making effective nutrient removal important for preventing algal blooms in downstream waters.
