Important notes
Prerequisites
In certain cases, no permit under water law is required, but the project must be reported (currently still on a form ).
This includes:
- short-term pumping attempts,
- Groundwater lowering with a lowering level of less than 1.0 m and a maximum duration of four weeks with open dewatering (auxiliary construction drainage)
- and small-scale subsidence (e.g. when installing shafts) over a maximum of ten days with small vacuum filter systems,
- Sampling from groundwater measuring points (not subject to notification).
Documents required
Information on the planned lowering measure and an excerpt from the field map / site plan with the entry of the system location (further systems see the form).
Please note
Due to staff shortages, there are currently extended processing times when issuing water law permits for temporary groundwater lowering. The average processing time is currently 3 months. Be sure to plan for this additional time requirement and submit the necessary applications in good time.
Deadlines
Applications for permission to lower the groundwater level should be submitted eight to ten weeks before the start of the measures.
A notification of a minor, temporary groundwater lowering must be received 2 weeks before the start of the measure.
