Water licence - heat pump/ cooling system up to 50kW

Anyone operating a groundwater heat pump or cooling system and thus pumping or infiltrating groundwater via a well requires a permit under water law.

Contact points

Course description

In principle, groundwater-operated heat pumps are possible throughout the city. One exception is the Waldtrudering water conservation area.

Note: In the south of Munich, the groundwater is relatively deep (15 to 25 metres) and in districts such as Solln or Großhadern there is little groundwater in some areas.

We therefore recommend that you ask us about the groundwater levels at your location for reliable planning:

The documents must be sent digitally by e-mail!

a separate notification is required for the drilling of the wells!

Prerequisites

The project comprises a groundwater heat pump or cooling system with an output of up to and including 50 kW. The property on which this is to be installed is located outside of contaminated sites entered in the land register and outside of water protection areas.

Required documents

All documents are required in paper form in 1 copy and also digitally by e-mail:

  • informal letter of application
  • General site plan 1:25,000 with labelling of the property
  • Site plan 1:1,000 with locations of the wells and the plant
  • Well development plans and geological strata profile with still water level (if drilling has already been completed after drilling notification). Alternatively: Anticipated layer profile and planned well development plan (if the wells have not yet been drilled).
  • Expert opinion from a private expert in water management (specialising in "thermal utilisation"). The information that must be included is set out in the information sheet under "Links and downloads". A list of authorised private experts can also be found under "Links and downloads".
