FIELD: water supply.
SUBSTANCE: invention relates to water supply and can be used in regulation of underground water discharge of aquifers for improvement of reliability of water intake and its increase, mainly in coastal sea areas. Method includes creation in water-bearing formation of hydraulic curtain, creating along hydraulic line shaft, by supplying to formation water and raising level of underground water in it, at that, under water intake to the water-bearing horizon highly purified waste water is supplied by the high and low intensity cavitation influence on it, prior to feeding into water-bearing horizon purified water is deaerated and cooled to temperature 2-3 degrees below submarine unloading underground water temperature, and when water is supplied to an underground horizon, a gravity discharge is arranged, bringing the water velocity to filtration rates of the underground horizon, and its flow is changed from a turbulent flow into a laminar flow.
EFFECT: method increases efficiency of water abstraction of underground water, increases degree of use of underground water in coastal sea areas by means of their artificial filling without deterioration of quality of underground water and prevent their irreversible losses due to their supply to submarine horizons, as well as to prevent supply of sea salt water in underground horizons.
