Drilling and working in groundwater

Drillings that reach so deep into the ground that they could reach groundwater are subject to notification and in some cases require a permit

Contact points

Course description

Drillings that only tap quaternary gravel and are not located in the water protection area may be commenced one month after receipt of the notification with complete documentation, provided that the work has not been prohibited within this period

Notifiable boreholes that only tap quaternary gravel and are not located in the water protection area include, for example

  • undeveloped boreholes such as exploratory boreholes and ground soundings
  • Groundwater measuring points
  • Wells for the thermal utilisation of groundwater with a heat pump or cooling system
  • Construction of a geothermal probe
  • Construction of a well for garden irrigation

You require a permit under water law for the following boreholes:

  • through groundwater-protecting layers (clay, sand, silt)
  • through several groundwater levels
  • into pressurised water

The documents required for this can be found under "Documents and links" in the PDF "Description of required application documents for boreholes, wells, groundwater measuring points in deep groundwater".

Please note

The maximum groundwater level is decisive for the obligation to notify.

If groundwater is tapped unintentionally, this must be reported immediately to the Department of Climate and Environmental Protection (Water Law Division).

Required documents

The documents should preferably be submitted digitally.

  • Completed notification form
  • General site plan M 1:25,000 with marking of the location
  • Detailed site plan M 1:5,000 or M 1:1,000 with entry of the project
  • Expected layer profile of the subsoil (for groundwater measuring points with schematic expansion plan)

Duration and costs

Processing time

Maximum one month.

Legal basis

§ Section 49 of the Federal Water Act (WHG)Article 30 of the Bavarian Water Act (BayWG)
