Raszewy Wastewater Treatment Plant, Wielkopolskie, Poland

Raszewy wastewater treatment plant is located in the village of Raszewy, within gmina Żerków, powiat jarociński, in the Wielkopolskie Voivodeship of Poland. The facility serves a population of 2,427 and operates under secondary treatment, a standard level for small agglomerations in Poland. As a plant serving fewer than 10,000 people, Raszewy falls under Poland's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland discharges from agglomerations of this size. The plant has a designed capacity of 3,333 m³/day and currently discharges 346.05 m³/day of treated wastewater. The treated effluent is discharged into local watercourses that ultimately drain into the Warta River basin, part of the Oder River system flowing into the Baltic Sea. The plant plays a key role in protecting local streams and groundwater from untreated sewage, supporting aquatic life and water quality in the region.

The plant discharges into small streams within the Warta River catchment, which flows into the Oder River and then the Baltic Sea. The local watershed supports diverse aquatic habitats and is used for agriculture and recreation. Proper treatment helps prevent nutrient pollution and protects downstream ecosystems.
