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.
