Pawlikowice Wastewater Treatment Plant, Pomarzany, Poland

Pawlikowice is a secondary-level wastewater treatment plant located in Pomarzany, within the gmina Krośniewice, powiat kutnowski, województwo łódzkie, Poland. The plant serves a population of 5,799 and operates as part of the municipal wastewater infrastructure in the region. As a secondary treatment facility, Pawlikowice meets the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary biological treatment for agglomerations with a population equivalent (PE) between 2,000 and 15,000. The plant's designed capacity of 14,999 m³/day aligns with this scale, ensuring effective organic matter and suspended solids removal before discharge. The treated effluent is discharged into local watercourses that ultimately drain into the Vistula River basin, contributing to the Baltic Sea catchment. The plant plays a key role in protecting downstream aquatic ecosystems from nutrient pollution, supporting water quality in the region's rivers and lakes.

The plant discharges into local streams that flow into the Bzura River, a tributary of the Vistula, which empties into the Baltic Sea. This watershed supports diverse aquatic life and is part of a region where agricultural runoff and urban wastewater can contribute to eutrophication. The plant's secondary treatment helps reduce nutrient loads, protecting downstream water bodies and the sensitive Baltic Sea ecosystem.
