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.
