Health advice and precautions for cleaning up your flooded home 

Disposal of sandbags

Sand bags tend to retain contaminants such as sewage and oils when they come into contact with floodwater. Ensure you wear gloves and wash hands thoroughly when handling.  There are a number of ways you can dispose of used sandbags:

  • At your local reuse and recycling site 
  • Empty the sand from the bag and keep the sand (for garden or other uses) and place the bags in your normal waste bin
  • Empty the sand from the bag, take the sand to your local reuse and recycling centre and place the bags in your normal waste

If sand bags did come into contact with flood water you should inform the staff of this when you take them to your local reuse and recycling centre.

Unused sand bags can be kept in a dry shady place so they can be used again if needed in the future.  Sacking material is normally biodegradable and will perish if left in place for a long time. It is therefore advisable to empty sacks and keep them dry for re-use. Store the sand in your garden, or yard for future use.


  • Dump rubbish into ditches as this may end up blocking trash screens
  • Sweep rubbish and leaves into  gullies/drains and this blocks them
