Kiaczyn Wastewater Treatment Plant - Kiączyn, Poland | Secondary Treatment Facility

The Kiaczyn wastewater treatment plant is located in the village of Kiączyn, within the gmina Kaźmierz in powiat szamotulski, województwo wielkopolskie, Poland. This facility serves a population of approximately 909 residents, making it a small-scale municipal treatment plant in the region. As a secondary treatment plant, Kiaczyn employs biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 8233 cubic meters per day, with a reported discharge volume of 129.61 cubic meters per day. Under the EU Urban Waste Water Treatment Directive 91/271/EEC, plants serving agglomerations under 2000 population equivalent are subject to appropriate treatment requirements, which secondary treatment fulfills. The treated effluent from the plant is discharged into local surface waters, which ultimately drain into the Warta River basin and then to the Oder River, flowing into the Baltic Sea. The plant plays a key role in protecting the local watershed from nutrient pollution and supporting aquatic ecosystem health.

The Kiaczyn plant discharges into local streams that are part of the Warta River catchment, a major tributary of the Oder River. The Oder flows into the Szczecin Lagoon and then the Baltic Sea. The region's waters support diverse aquatic life and are important for migratory fish. Nutrient removal from wastewater helps prevent eutrophication in downstream water bodies.
