Water law permission for groundwater lowering

In the case of construction measures, temporary groundwater lowering may be necessary to keep the excavation pit dry and/or to avoid a hydraulic ground fault. For these groundwater lowerings, you must apply for a permit from the water authority before starting the measure.
