Erlaubnis für einen Erdaufschluss beantragen

§49 para 1 sentence 2 WHG

If you are planning a deep borehole or a geothermal exploration for geothermal use with a vertical geothermal probe, you will need permission from your local water authority.

Drilling work that goes so deep into the ground that it can affect the movement or composition of the groundwater is referred to as "ground excavation". If you are planning such an exploration for geothermal use with a vertical geothermal probe, you must apply to the relevant water authority.

Each borehole provides data for the evaluation of the subsurface at the respective location. The notification enables the responsible authorities to gain an impression of the drilling project and the drilling material produced on site. The authorities can take additional measurements and ensure the quality of the drilling results. This prevents costly mistakes in underground spatial planning.

You must apply for the permit before starting the work.

You can only start your project once your competent authority has granted permission.

• Drilling/excavation work that may affect the movement or composition of the groundwater must be notified.
• A permit must be applied for when specifically planning a borehole for geothermal use with a vertical geothermal probe.
• The project may not commence until the competent authority has issued this permit.
• The competent authorities are determined by the location of the planned drilling points, usually the lower water authorities
