The study analyses the efficiency of pollutant removal by three small wastewater treatment plants located in the rural areas of the Lublin province. The first of them is a household plant having a soil-plant bed with Salix viminalis. The second is a BATEX-B5-type household plant with a filter drain. The third one is a small treatment plant with Phragmites australis. Investigations carried out in 2001 revealed that the plants did not always meet the expectations as the effluents were not adequately clean and contained wastes, mostly bionic compounds, in concentrations exceeding the relevant standards. It is suggested that the development and modernisation of the plants might improve the effects of pollutant removal.
