  • Procedure

    Notification can be made in writing or, depending on the district administrative authority, also electronically.

    The notification is examined by the responsible district administrative authority, if necessary with the involvement of the water management authority. An examination is carried out with regard to restrictions on earth excavation at the planned location or whether the procedure must be discontinued.

    Furthermore, a decision is made as part of this review as to whether further procedures need to be carried out in addition to the notification, e.g. a permit procedure under water law.

    The relevant result will be communicated in writing by the competent authority.

  • Notes

    In addition to the notification to the district administrative authority in accordance with the Water Resources Act/Bavarian Water Act, all earth excavations (drillings, wells, etc.) must also be reported to the State Office for the Environment (LfU).

    The LfU must be notified at least two weeks before the start of the investigation. The LfU offers an online application for digital notification (see "Related links" and "Related services"). After completion of the work, all data obtained must be submitted to the LfU.

  • Processing time

    If you have not received a response from the responsible district administrative authority within four weeks of your notification (with complete documentation), you may start work and continue until groundwater is affected.
