In the year of Cheboksary hydroelectric power station’s anniversary, the authors of the article aim to investigate the issue of the waterworks facility’s formation in the early 40s of the last century. Based on the principles of historicism and objective analysis, the main stages of implementing the HPP construction plan are considered. The article presents archival documents which examine the problems of decision-making on the construction of the object. The issue of constructing hydroelectric power stations on the Volga, in particular in the territory of Chuvashia, was studied in the specially created Bureau «The Great Volga». Simultaneously with the construction of Cheboksary HPP, the construction of two more stations – Yaroslav­skaya and Balakhninskaya – was considered. The authors present comparative characteristics of the objects. Cheboksary hydroelectric power plant in terms of its performance significantly exceeded other structures. The article notes that prior to the construction of the station, a lot of preparatory and survey work was carried out, which was limited by a tight deadline. As a result of examining the scope of work, material resources and labor costs, the construction of the station was postponed to a later date. Scientists and engineers recognized the priority need to build less powerful stations. The materials of the article can be used for further research of this topic, as well as when writing regional natural history works.

The goal of the project is to develop and use a hydrocyclone sand trap to improve the operation of a mini hydroelectric power station. In contrast to the existing design of a similar type of hydroelectric power station, a bulky sump for water purification has been replaced with an efficient hydrocyclone device. Due to this, a simplification of the design of the HPP is achieved, an increase in the degree of sand collection from the composition of the water used. Research methods. The initial data for the calculation were taken: the flow rate of water passing through the hydrocyclone and the pressure drop at the inlet and outlet of the hydrocyclone. Computer simulation of the process was carried out using the SolidWorks software (flow simulation). The main technological parameters and a rational mode of operation were established by testing experimental samples both in laboratory and in production conditions. Research results. In the established mode, the density of clarified water is equal to 1.009 ... 1.050 t / m3, and the degree of purification is 91 ... 97%. Replacing a bulky reinforced concrete sump with hydrocyclone sand traps of a simplified design reduces the cost of building a water treatment unit from 30% (existing) to 7%. This makes it possible to expand the volume of development of small hydroelectric power plants, especially in mountainous conditions.

The “Farkhod Hydroelectric Power Station” which was built in Syrdarya region has irrigated 700,000 hectares of fertile land in Dalvarzin and Mirzachul districts of Uzbekistan, Tajikistan and Kazakhstan. “Andijan water reservoir” was built in the Karadarya River of Fergana Valley, and a hydroelectric power plant with a capacity of 140,000,000 kilowatt-hours was commissioned. Due to the commissioning of “Tuyamuyin” waterworks in the lower reaches of the Amudarya River, it was possible to irrigate 300,000 hectares of land in the Republic of Turkmenistan and Uzbekistan, as well as 200,000 hectares of new land for rice and cotton growing. In addition, this water facility has protected the land from erosion and provided with 150,000 kilowatts of electricity.

Purpose. Analysis of environmental problems and risks associated with the construction and operation of small hydroelectric power facilities (SHEPP) in the Ukrainian Carpathians. Methods. Field studies, statistical, hydrological, hydroecological, analysis and synthesis. Results. Potential environmental risks arising from the construction and operation of SHEPP in the Ukrainian Carpathians are considered. The influence of Yavіrska hydroelectric power station on water discharges in the Stryi river was investigated. The daily water discharges for the two hydraulic sections located above and below the station for low-water (2003) and high-water (2008) years are analyzed. Possible risks in the construction and operation of the hydroelectric power plant for the movement of flood waters, river sediments, the development of riverbed deformations, and others, are indicated. The difference in water discharges between the two hydrological stations is presented, and it is confirmed that in the spring of 2008 and 2003 and the autumn and winter of 2003 and 2008 minimal differences in water consumption were observed as a result of the water retention in the reservoir above the dam of Yavіrska hydro power station for the maximal electrical power generation. The impact of the Yavіrska SHEPP on the biota of the Stryi river during 2014–2015 was analyzed. The obtained results indicate that the main negative factors affecting the communities of river hydrobionts are the creation of reservoir of limnethic conditions in the continuum of the river ecosystem; the accumulation of sediments and dead organic matter on its bottom and banks and the demolition of these sediments on the lower sections of the channel bed; also a decrease of water in the riverbed downstream of the dam after the closure of the floodgates in June. The analysis of the environmental impact assessment reports made it possible to analyze the major environmental threats, which are possible during the building and operation of a small hydroelectric power plant on the Stryi river in the Dovhe village (Drohobych district, Lviv region). Conclusions. To prevent the impact of the projected SHEPP in the Carpathian region it is necessary to prescribe the mechanism of carrying out the environmental impact assessment, to specify the natural-geographical, hydrological and hydro-ecological restrictions on the construction and operation of the hydroelectric power station. It is also necessary to identify sections of mountain (“wild”) rivers with high values of natural landscapes and prohibit the construction of small hydropower facilities.
