Krzeczow Wastewater Treatment Plant, Krzeczów, Poland

The Krzeczow wastewater treatment plant is located in Krzeczów, a village in the Łódź Voivodeship of central Poland. This facility serves a small population of 492 residents, reflecting its role in a rural community. The plant is situated inland, far from the Baltic Sea coast, and operates under Polish environmental regulations. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Although the directive mandates secondary treatment for all discharges from agglomerations above 2,000 population equivalent, smaller plants like Krzeczow are still expected to meet national standards. The facility has a designed capacity of 6,577 m³/day, but currently discharges 70.15 m³/day, indicating significant spare capacity. The treated effluent is likely discharged into a local watercourse that feeds into the Warta River basin, part of the Oder River system, which ultimately flows into the Baltic Sea. The plant's operation helps protect local streams and groundwater from untreated sewage, supporting the ecological health of the region's aquatic habitats.

The plant discharges into a local water body within the Warta River basin, which drains into the Oder River and eventually the Baltic Sea. This inland location means the effluent influences small streams and groundwater, affecting local biodiversity. The region supports mixed agricultural and natural landscapes, so maintaining water quality is important for downstream ecosystems and drinking water sources.
