<p><span lang="EN-AU">Against the background of global climate change, anthropogenic impact on the environment, population growth, expansion of irrigated areas, development of industry, energy and other sectors of the economy, there has been a shortage of fresh water in a number of countries around the world. The earth is already experiencing a serious water problem. According to UN experts, more than 500 million people worldwide suffer from various infectious diseases due to drinking poor-quality water, and 5,000 people die daily due to lack of drinking water. River water is mainly used for drinking water supply to the population, industry and industrial areas, as well as for irrigation of agriculture. However, the water resources of the rivers are extremely limited and unevenly distributed over the territories. When using groundwater, various hydraulic engineering devices are used, including artesian and subartesian wells, horizontal and girder aquifers, spring water extraction devices, and ancient kahris. Among these aquifers, the ancient kahrizas are fundamentally different from other devices due to their unique design, principle of operation and lack of energy requirements.</span></p>
