General information
Groundwater lowering or groundwater maintenance required in the course of construction measures are uses of water bodies that generally require a permit.
As an exception, groundwater lowering for smaller construction measures, such as for the installation of a shaft or for the excavation pit of a building, can be assessed as permit-free if a withdrawal of approximately 10 cubic meters per day (m³/d) is not exceeded and these are only operated for a "short" period of time. Such groundwater lowering must also be reported to the water authority in writing with the relevant documentation. The water authority then decides whether the measure does not require a permit or whether a permit under water law is required.

Fees
The state of Lower Saxony charges a water withdrawal fee (WEG) for the withdrawal.
