Overview
Zawada wastewater treatment plant in Kolonia Zawada, Poland, serves a small population of 474 with secondary treatment. The plant is currently closed.
Zawada is a wastewater treatment plant located in Kolonia Zawada, a settlement in the Tomaszów Mazowiecki municipality of Łódź Voivodeship, Poland. Designed to serve a population of 474, the plant provided secondary treatment before its closure. The facility had a designed capacity of 2,667 m³/day and discharged 67.59 m³/day of treated effluent. As a small agglomeration, the plant operated under Poland's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland communities of this size. The treated effluent from Zawada would have discharged into local waterways within the Vistula River basin, which ultimately drains into the Baltic Sea. The region's aquatic ecosystems rely on proper wastewater treatment to maintain water quality and support biodiversity.
Environmental context
The plant's discharge would have entered local streams in the Pilica River catchment, a tributary of the Vistula River. The Vistula flows northward through Poland and empties into the Baltic Sea via the Gdańsk Bay. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. Proper treatment of wastewater from small communities like Kolonia Zawada helps reduce eutrophication risks in downstream waters.
