The water buried under the ground surface in various states is commonly called as underground water, the underground water source is abundant, and people can widely exploit and utilize the water in the early years; in recent years, the underground water is used as a renewable energy source and applied on a larger scale, and when the underground water is used, the underground water is pumped out from a heat source well, and the heat in the water is utilized by a unit and then is recharged into the heat source well.

In the past, the first generation utilized a pumping well to pump water directly, but the pumping water source was naturally discharged on the spot after use, which resulted in the water level of the groundwater dropping rapidly to form a groundwater funnel, causing ground subsidence and collapse, and the water amount of rivers and lakes decreasing to form disasters such as dryness. The second generation is to drill more than two wells at a short distance, wherein one well is a pumping well for pumping water, the other well is a recharging well for recharging the used water immediately, and the water is returned to the ground by utilizing the temperature and heat energy characteristics of the water, so that a series of problems of water level reduction, ground subsidence and the like are solved.
