If you want to extract large quantities of groundwater, you need a permit under water law. You can apply for this from the responsible authority. They will examine your application and decide whether you will be granted a permit.

The authority may have to carry out a formal administrative procedure. This gives those involved the opportunity to comment on the project. To this end, the authority publishes the project and, if necessary, holds an oral hearing.

The permit specifies the type and extent of use. It may be subject to conditions and ancillary provisions. In contrast to an authorization, a permit can be revoked by the authorities. There is no legal entitlement to the use of groundwater.

You do not need a permit under water law if you only extract groundwater to a small extent and without any adverse effects on the water balance, for example for

• your own household,
• watering your garden,
• for farm operations,
• watering livestock or
• the drainage of land.
