Do you want to carry out drilling or other earthworks that could affect the movement or quality of the groundwater? Then you must notify the competent authority in advance.

If you want to carry out so-called earth excavations, you must notify the competent authority.

Earth excavations are boreholes or other earthworks that reach so deep into the ground that they can affect the movement or composition of the groundwater.

Notification is required for the following projects:

• Exploration of old mines or cavities
• exploration of contaminated sites
• wells
• geochemical investigation
• geophysical investigation
• Geothermal utilization with groundwater heat pumps
• Drilling and pumping or absorption test
• Groundwater measuring point
• Engineering geological investigation or subsoil investigation
• Mapping (except base drilling)
• Raw material exploration drilling
• Other exploration purposes

Once you have notified us of your planned ground exploration, you can start drilling.

Each borehole provides data for the evaluation of the subsoil 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.

The water authority responsible for your project is determined by the location of the planned drilling points.

• Contradiction

• Earth excavation Notification of receipt of work with a direct or indirect impact on groundwater
• Drilling work or earth excavations that may affect the movement or quality of groundwater must be reported
• Work must be reported to the responsible authority at least 1 month before commencement
• Construction work may begin after the notification has been submitted
• Competent:
  • Competent authorities are determined by the location of the planned drilling points
  • Lower water authorities
