You can use this online application to report a drilling operation (as an organization).
Convenient for residents and digital: Simply fill out this online application directly in your web browser. In many cases, this saves you a trip to the government office.
Anyone who drills a hole, constructs a well, or performs other work that penetrates the ground to such a depth that it could affect the groundwater must report this to the competent district administrative authority.
The obligation to notify generally rests with the project owner. If the project owner hires a drilling company, the drilling company must inform the district administrative authority.
When using the online procedure described above, legal entities need a “My Business Account” (ELSTER organizational certificate) to log in, and individuals need a BundID (ELSTER certificate or online ID).
The notification must be filed with the district administrative authority. Please use the online procedure mentioned above for this purpose.
The district administrative authority responsible will review the notification, with the Water Management Office participating as necessary. The review will assess whether there are any restrictions on excavation at the proposed site or whether the procedure must be discontinued.
Furthermore, as part of this review, a decision will be made as to whether additional procedures beyond the notification are required, such as a water rights permit process.
The relevant authority will notify you of the result in writing.
Please use the online procedure mentioned above to submit the drilling documentation.
Under the Geology Data Act, which applies nationwide, all drilling operations must be reported to the Bavarian State Office for the Environment (LfU) two weeks before work begins (see “Related Topics”). If you use the online procedure mentioned above, you will also be fulfilling the notification requirement under the Geological Data Act.
The notice must be filed at least one month before the planned start of the work.
If one month has passed since the notice was filed without an order to suspend or remedy the situation having been issued pursuant to Section 49(3) of the Water Resources Act (WHG), the work may begin and continue until it affects the groundwater.
