PURPOSE:To be able to utilize the heat of ground water at a specified aquifer by a method wherein the inner upper and lower parts of a water catchment tube are arranged to correspond to the upper and lower parts of the aquifer and a heat exchanger is placed at a compartment between the upper and lower parts of the tube. CONSTITUTION:Fluid is allowed to flow into an upper and a lower bag-shaped water stop bodies 15, 19 in a catchment tube 3 by a fluid supply tube 18, which are located at the upper and lower parts of an area A corresponding to a primary aquifer 1 and the bodies are expanded to adhere closely to the inner surface of the tube 3. Afterwards, water C on the ground is sent to a heat exchanger 5 placed at the intermediate part between the bodies 15, 19. The ground water in the aquifer 1 flows into the tube 3 from a water absorption hole 4. The heat of the ground water D heats the water C with the exchanger 5. The heated water C is spouted from a spouting tube 12 and accumulates above the body 15 and is sent to a sprinkler tube 23 by a submersible pump 13. Further, the body 15 is moved to the upper part of a secondary aquifer 2 to utilized the ground water E in the aquifer 2.
