There are considered issues of assessment of the anthropogenic load on water bodies, identified the following indicators of loading: the annual volume of water resources withdrawal for irrigation, the maximum amount of withdrawal in the vegetation period, the volume of drainage runoff, chemicals and biogenic elements. Depending on the mineralization and qualitative content of the drainage flow there are proposed directions for the reduction of the anthropogenic load: the intersystem usage for irrigation of fodder and technical crops; for domestic needs and livestock watering, cleaning and demineralization of drainage flow; evaporation and discharge on the terrain relief. The methodological basis of the research is the analysis of the existing Russian system of rationing, determination of the permissible level of the anthropogenic load on water bodies and consideration of technical and economic capabilities of the regional water management to achieve the required performance of waste water treatment. The result of the research is the substantiation of the integral indicators of the anthropogenic load on water bodies under the functioning of reclamation systems including the annual withdrawal of water resources for irrigation, the maximum amount of withdrawal in the vegetation period, the volume of drainage runoff from reclaimed areas during the warm period, the volume of pollutants discharged from irrigated areas in water bodies (drainage, waste and wastewater diffusion). The scientific novelty of the research is a theoretical substantiation of possible ways to reduce the discharge of drainage water into water bodies, depending on its mineralization and quality. The practical significance of the research determines the possibility of using the proposed technical solutions under technical re-equipment, reconstruction and new construction of drainage systems in the implementation of the program of land reclamation development by 2020.
