The aim of the research was to ensure the environmental sustainability of the development (EUR) of the watering irrigation systems by increasing the initial energy use in the crop production technology in irrigated lands. At the current stage of water industry development as a part of agroindustrial complex there is an important task connected with the increase of efficiency of the initial energy use in crop production technology through the use of renewable energy sources-the potential energy of water flow on intrasystemic hydrotechnical waterworks of open and closed types with the use of small HPPs and micro HPPs on sprinklers, solar batteries to provide electrical power to the intrasystem elements of watering irrigation systems, wind driver generators in the life sustenance of people living in the zone of watering irrigation systems. In the system energy-entropy consideration of the processes of functioning watering irrigation systems, certain changes in the environment (PS) that form the ecological state (ES) as a factor of environmental safety (EB) in the zones of influence of existing watering irrigation systems occur. The provision of EUR and the functioning of the natural-technical systems "natural environment-watering-irrigation system-population" (PTS "PS-OOS-N") is important for the further improvement of watering irrigation systems. To ensure the EUR of the existing and newly developed PTS "PS-OOS-N", the development of the methodology basics for assessing the environmental sustainability of the development of watering irrigation systems as a factor of environmental safety and accordingly the development of agricultural production in irrigated lands by more fully utilization of the initial energy source under the influence of which all processes of vital activity within the given basin-geosystem occur is required.
