Well drilling; display

If you want to drill a well, you must indicate this.


Work that penetrates so deeply into the ground that it may directly or indirectly affect the movement, elevation, or character of groundwater shall be reported to the appropriate authority. Among other things, the construction of a well must be reported.

If a well drilling company is commissioned with the sinking of the well, this company is obliged to give notification.

If a well is sunk without prior notification, this constitutes an administrative offense with a fine of up to 5,000 euros. In addition, in such cases it may also be necessary under certain circumstances to dismantle the well again in a professional manner.


You intend to drill a well from which you want to extract water.


You must submit the notification to the competent lower water authority (district office or independent city).

Within the scope of the notification, the responsible authority will check, in particular with the participation of the water management office, whether or, if so, under which restrictions the installation of the well at the intended location is possible. Furthermore, it will be decided within the scope of this examination whether a permit procedure under water law must be carried out in addition to the notification. The result of this examination will be communicated in writing by the responsible authority. If the competent authority does not prohibit the construction of the well within one month after receipt of the complete notification, the well can be constructed in the form notified if the planned use is permit-free.

The drilling company must submit the drilling documentation after completion of the drilling work without further request. These are:

  • Well design plan with strata list and drilling profile,
  • Measurement of the well top edge to NN (normal zero)
  • Site plan with the exact well location as well as
  • Pumping test diagram (water level at rest/sinking of water level at full pump load) in duplicate.

Special notes

The Bavarian State Office for the Environment (LfU) must be notified of all boreholes two weeks before work begins (see under "Related Topics").


The notification must be made at least one month before the planned start of the work.

    • General plan with marking of the project location
