Presented in the paper are preliminary results of examining reduction in concentrations of pollution load in rural sewage utilized for watering energy plants. The purpose of the paper is to determine the efficiency of biological cleaning of rural sewage and degree of pollution of water for agricultural utilization of rural sewage. The studies were conducted in lysimeters using two species of energy plants: Miscantus giganteus and Sida hermaphrodita Rusb in two variants of fertilization. The studies showed high effectiveness of cleaning resulting from indices of oxygen reduction, indices of pollution with biological cleaning of sewage in soil-plant environment with simultaneous production of biomass for energy purposes. Reduction in pollution load expressed in BOD5 ranged from 84.9-99.6% and in case of COD 64.1-98%.
