FIELD: construction. ^ SUBSTANCE: invention concerns water supply and can be used in regions and areas experiencing energy shortages. The water supply well includes an underground aquiferous zone, through which a well is drilled, water-lifting string, gas hood with outlet connected to the water-lifting string, upper end of which is close to the well head and connected to the water consumer's reservoir, feeding pipeline with connected to it dart valve and remotely controlled dart valve. The outlet interval has a "dry" volume. Dynamic level in the outlet interval is located below the discharge line pipe edge. Connection between the feeding line and outlet interval is located above the pressure valve inlet. The "dry" volume of the outlet interval is connected via a hose to the atmosphere at the well head. The gas hood is fitted with a tray with liquid, for example, with water, the tray is floating on the water plane pumped in the tray, and with a fixed perforated cartridge with a substance, for example, calcium, which can come into contact and react with the water in the tray to release gas. ^ EFFECT: use of the water supply well in wider geological conditions, particularly in conditions, which require no fractured (connection) zones, which extend from the "dry" volume of the outlet interval up to day surface. |
