Energy from the groundwater
Detailed information

 

Withdrawal of groundwater

In a first step it is determined if sufficient groundwater is present at the location . If this is the case, a drilling can be realized, after all grants are present and in accordance with the necessary heat requirement and the available groundwater conditions. With a pumping test and a chemical analysis it is determined how much groundwater can be maximally withdrawed and whether the groundwater without additional technical precautions can be introduced directly into the heat pump.

Groundwater feed-back

In a second step will be clrified, how the the cooled-down groundwater can be led back again into the groundwater body. With a throughout permeable ground the water can be returned by means of a flat seep-well. If the underground- layers are however only well permeable in deeper depths, a second drilling must be realized.

Situation of the wells

With the construction of the plant, it must be paid attention to the fact that the supply-wells lies in the in-current and the return wells in the out-current area of the groundwater, since otherwise this cools down continuously.
