Well drilling; display

The competent authority must be notified of any work that penetrates so deeply into the ground that it may have a direct or indirect effect on the movement, level or quality of the groundwater. Among other things, the construction of a well must be notified.

If a well drilling company is commissioned to drill the well, it is obliged to notify the authority.

If a well is constructed without prior notification, this constitutes an administrative offense for which a fine of up to EUR 5,000 is imposed. Furthermore, in such cases it may also be necessary under certain circumstances to dismantle the well professionally.

• The following documents must be enclosed with the notification:
  • General plan with marking of the project location
  • Detailed location plan with entry of the project site
  • Expected layer profile of the subsoil
  • True-to-scale development plan according to DIN 4022 and Din 4023
  • Notice from the water supplier about the exemption from the connection and use obligation
  • If applicable, declaration of consent of the property owner
  • If applicable, certification according to DVGW W 120 of the drilling company in case of first-time notification.
  • If applicable, declaration of the drilling company commissioned

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

As part of the notification, the competent authority will check, in particular with the involvement of the water management authority, whether the installation of the well at the planned location is possible and, if so, under what restrictions. Furthermore, as part of this examination, a decision is made as to whether a permit procedure under water law must be carried out in addition to the notification. The result of this examination is communicated in writing by the competent authority. If the competent authority does not prohibit the construction of the well within one month of receipt of the complete notification, the well can be constructed as notified if the planned use does not require a permit.

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

• Well development plan with layer index and drilling profile,
• Measurement of the top edge of the well at NN (standard zero)
• Site plan with the exact well location and
• Pumping test diagram (water level at rest/lowering of the water level at full pump load) in duplicate

Fees for the examination of a complaint: EUR 25.00 to EUR 1,000.00

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