Maintenance of water protection systems
We take over the maintenance of water protection systems.
The following activities are carried out in the course of maintenance:
Sedimentation tanks:
- Check the inlet for contamination
- Functional check of the automatic locking device (inlet lock if available)
- Check the functionality of the relief devices
- Determine the thickness of the sludge layer
- Check the inflow into the bottom filter basin
- Functional check of the gate valves or flaps
Filter basin:
- Control of the inlet and outlet area
- Check the bottom filter (check for silting of the filter layers)
- Checking the permeability of the filter layers (If necessary, permeability tests are carried out in the filter basin. These will be charged separately.)
- Slope control
- Vegetation control up to the maximum water level of the soil filter basin
- Vegetation control outside the water level
- Functional check of the gate valve and mechanical installation parts
- Functional check of the relief devices
- Functional check of the drainage
- Recording of the current water levels in the pools
Discharge structure (e.g. hollows and finishes):
- Check for erosion
- Check for symptoms of scab
- Control of transfers and landings
- Check the backflow flap and the technical installation parts
Further the activities will be summarized in a report.
