The article examines the problem of fresh water, since in terms of water supply from its own resources per capita and per 1 km2, the republic is 8 times behind Georgia, 2 times behind Armenia. Significant water consumption in Azerbaijan is caused by its arid territory with a predominance of active temperature and a lack of precipitation, which leads to intensive irrigation of crops. At the same time, artificial irrigation is used on 70% of the cultivated land.

Aim. Study of the influence of drinking water quality on the ecologically-dependent morbidity of the population of the Republic of Dagestan.Material and Methods. Methods of current and retrospective analysis of regional health indicators and methods of mathematical-statistical and medical-geographical analysis were used. Statistical processing of the results was carried out using the STATISTICA and Excel software packages. When carrying out laboratory studies on the quality of drinking water, we used a Lumex atomic absorption spectrometer "MGA-915MD".Results. Numerous hygiene studies indicate the direct impact of unsatisfactory drinking water quality on the health of a population. The relationship between sanitary and chemical indicators and the incidence rate for a number of nosological forms has been proven. It is generally accepted that human health is influenced by lifestyle factors (working, living and relaxation conditions), heredity and the ecological condition of the area of residence, including the quality of drinking water. Although it is not possible to differentiate the share of the negative effect caused by the consumption of poor quality drinking water but the incidence of certain nosological forms (cancer of the esophagus, gastrointestinal tract and kidney diseases) in the those regions of the Republic of Dagestan under consideration correlates with the characteristics of drinking water.Conclusion. The problem of pollution of water supply sources for the population in the dynamics of the long-term remains a priority concern. The quality and safety of drinking water are decreasing, which cannot but have a negative impact on public health. Correlation linkages between indicators of drinking water quality and oncological morbidity of the population were also established in indicators below the maximum permissible concentrations, which corresponds to a typical logistic model of causal relationships and serves as evidence of the high dependence of health disorders on chemical contamination of water supply sources.

Healthy and safe drinking water in sufficient quantities provided to consumers improves living conditions, raises health culture at a higher level and promotes the environment as a whole. The aim is to see if there is a correlation between irregular water samples with intestinal infectious diseases related to drinking water. Materials and method. The preparation of the Republic Computer Program (1996) for issuing laboratory findings (RCP) from the analyses of samples of drinking water (physico-chemical and bacteriological), in accordance with the methodology for application of ID numbers in the computer system in the Public Health Centers has created the possibility of complete health records of drinking water supply facilities under health surveillance for the territory of the entire Republic. Evaluation has been made of the results of basic physicо-chemical and bacteriological analyses of drinking water in the settlements of the Republic of North Macedonia and the water-related diseases – waterborne intestinal infectious diseases in the period 2014-2018. Results. Drinking water from city water supply in the examined period in terms of physico-chemical analysis ranged 2.9-4.3%, while in relation to bacteriological analysis 0.9-2.6%.. Waterborne intestinal infectious diseases show a decline in their incidence in 2018. Conclusion. The registered data from the physicо-chemical and bacteriological analysis showed that the drinking water from the city water supply systems in the period 2014-2018 was safe. According to the processed data, access to safe drinking water for the population was 97% by 2018, which ranks the country in the group of countries in the world with the highest access to safe drinking water, and there is no significant connection with drinking water related diseases.

In the Republic of Moldova, in the field of public water supply services, corporate governance, from a conceptual and regulatory point of view, began to develop only in the early 2010s. The selected topic is current because corporate governance is at the early stage in this field, but, at the same time, its evolution for 10 years needs to be analyzed. This process must be monitorized to identify the most important successes or deficiencies in order to develop a set of good practices. The purpose of the research is to identify the relationship between degree of development of corporate governance and the profitability of companies in the field as well as shaping the corporate governance model. Research methods used refer to the observation of corporate and economic processes, interview, investigation, comparing, analysis of corporate legislative and regulatory documents in the field, induction, explanation and interpretation of the main indicators of corporate management. The relevant research results are: identifying the fact that there is no clear dependence between the application of corporate management and increasing the profitability of water companies; at the same time, it has been identified that the participation of employees of water companies in the company boards contributes to better profitability. The corporate governance model was configured, with the identification of deficiencies in the process of regionalization of services. Corporate governance, in the analyzed field, must be subjected of the process of continuous improvement in particular by evaluating the activity of the company’s board.

Agriculture is one of the most important elements of the economic complex of the Republic of Crimea, which is confirmed by the high development of territories, about 70 percent of the area. To eliminate the acute shortage of water, the article proposes an autonomous system powered by solar energy. This will make it possible to provide water for irrigation on agricultural land. (Research purpose) The research purpose is in searching for and justifying optimal technical solutions for eliminating the problem of water supply to agricultural enterprises of the Republic of Crimea. (Materials and methods) Authors have analyzed the agro-climatic features of the Crimean Peninsula. The article presents the data on the depth of the aquifer on the territory of Crimea, the annual energy potential of solar and wind energy. The article proposes a variant of water supply using artesian water extraction systems powered by solar energy. Authors have calculated the parameters of the solar water supply system. The article presents a diagram of its work. (Results and discussion) The main advantage of a solar installation for water extraction is the ability to use it autonomously in remote areas, without resorting to the construction of expensive engineering structures, which allows us to solve the problem of water supply locally. To ensure the irrigation rate of the apple tree on the territory of one hectare with sufficient solar insolation, a water-based photovoltaic installation is a suitable technical solution. The article presents the total capacity and area of the photovoltaic plant. (Conclusions) The area of the photovoltaic station does not exceed one percent of the total area of the irrigated field. This installation will make it possible to solve the problem of water supply in the region, increase productivity and the overall standard of living of the population.
