Cleaning rainwater tanks after floods or storms
Before returning home make sure you have an adequate supply of drinking water with you (e.g. bottled water or water from a town water supply).
Rainwater tanks (and bore water-holding tanks) impacted by storms and floods are likely to contain harmful microorganisms. This means the water stored in the affected tanks will not be suitable for normal use.
The tank water should also not be used if the tank or connecting pipework has been damaged, or where flood water has been in contact with taps or connections within or outside the home.
