Relevance. According to data of the international global economy research centers, 5,5 bln people or two-thirds of the world population will run into a fresh water shortages problem in 2025. Now the major reason for mass human migration from African countries to Europa, USA and Canadais the drinking water sources failureand as a result the poor living standard. In the next 65 years drinking water consumption will grow exponentially. The drinking waterisakey to geopolicy of XXI century. So groundwater extraction development questions are eagerly sought and important now. The Aim of research is to take on the task of effectivegroundwater extractionwhile creating conditions for the normal manifestation of the internal energy of aquifers in combination with the physical principles of water withdrawal, as well as the possibility and feasibility of using high-pressure jets in PDC drilling bits for drilling rocks of VII-VIII drillability grades. Methods. We practiced the experimentative-analytical method using an experimental observable circulating system set-up supporting visual observations of the water motion modeas well as the establishment of the resource capabilities of the circulation system for the development of underground water deposits by injection-forced self-pouring. The existing methodology for exploration and development of groundwater deposits by drilling vertical wells is obsolete. The applied method of drilling wells does not correspond to the geological and technical conditions of the mountainous environment, hence the technological complications and low fluid yield of hydrological wells. Improving the efficiency of opening and developing groundwater deposits is an urgent task. And this is possible when creating conditions for the presentation of the internal energy of aquifers in combination with the physical principles of water extraction and its rise to a height without energy expenditure. Results. According to the analysis and generalization of the results of analytical and laboratory studies of resource capabilities, a circulation system for the development of underground water deposits by injection-forced self-flow is proposed. the expediency of equipping the descending shaft with the layout of the hydraulic jet apparatus, oriented to the elements of occurrence of aquifers, has been established. The initiation of an incomplete water hammer in the layout of a hydraulic jet hydraulic device creates a dynamic depression on the aquifers with the effect of injection and the force of a hydraulic ram. The proposed circulation system can be used to extract water from low-pressure aquifers.
