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

Course description

In principle, groundwater-operated heat pumps or cooling systems 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 very little groundwater in some areas.

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

• request information about groundwater

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 must be submitted digitally by e-mail and also in a single paper copy:

• 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 heat pump or cooling system
• If drilling has already taken place after drilling notification: Well development plans and geological layer profile with water table at rest Alternatively, if the wells have not yet been drilled: Anticipated layer profile and planned well development plan
• 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". Alternatively, only in the procedure for renewing a permit: Confirmation by a private expert in water management (with the field of activity "thermal utilisation") after the on-site inspection of the system that the system complies with the requirements of the original decision and has no significant defects.

A list of authorised private experts can be found under "Links and downloads".
