Well construction (hydrothermal groundwater use + irrigation)

The production well is to be built with a borehole diameter of 600 mm to a depth of up to 18.0 m below GOK and a support diameter of DN 300. The submersible feed pump shall be installed in an unfiltered area at a depth of approximately 14,5 m. The boreholes are drilled with DN 300 winding wire filters.

The groundwater reintroduction is to be carried out via a swallowing well with a drilling depth of approx. 11.0 m below GOK and a drilling diameter of 600 mm. DN 300 was chosen as the support diameter. The downspout must be routed below the groundwater level,

to avoid chemical precipitation.

The exploratory well is to be used as a production well for irrigation (FB 2). For this purpose, the above-ground closure (concrete base, SEBA cap and steel protection pipe) is to be dismantled and a well room is to be built at the existing exploratory well.
