The paper describes the experience of restoration of the lands disturbed by the mining industry by applying proper water management of worked-out quarries reclamation. The necessity of works on regular maintenance of the anthropogenic techno-ecosystem and artificial reservoirs is highlighted. Water quality is considered to be one of the most important characteristics of water resources that determine the possibility of their rational use. Most artificial lakes are characterized by high water content of sulfate ions. Oxygen is one of the most important dissolved in water gases. The dynamics of its content is determined by physicochemical and biological processes, and the uneven vertical distribution of oxygen in the lake is accompanied by the formation of products of anaerobic decomposition of organic matter such as hydrogen sulfide, methane, and ammonia.The use of aeration systems in the world allows considering aeration as an effective tool in conditions that are critical for hydroecosystems. Aeration methods can enrich water with oxygen and improve the ecological condition of the artificial lake. The paper shows the environmental advantages of using wind energy compared to the energy generated by burning different types of fuel. In the course of research calculations were made for the operation of a water pulverizing aerator designed by Podsyadlovsky in the location of Yavoriv artificial lake (Western Ukraine). The location of the lake is favourable for tourism development as it can provide various types of recreation for both local and transit holidaymakers.The environmental advantages of the wind drive of the water pulverizing aerator designed by S. Podsiadlowski for reclamation of Yavoriv artificial lake are mathematically determined and analyzed. The environmental effect is related to the benefits of replacing the energy obtained by burning fossil fuels at a power plant with wind energy. The environmental effect, which is determined in the process of mathematical calculations and on the basis of regression equations, complements modern knowledge in the field of bottom water aeration with the use of a water pulverizing aerator based on the Podsiadlowskis concept.
