Cleaning up after a flood

Floodwater can be contaminated.

Following some simple rules when cleaning up can help reduce and prevent any additional health problems from the contaminated water.

  • Always wear protective clothing while cleaning up including waterproof boots and gloves.
  • Bacteria such as E. coli 0157 is often found in floodwater. Although it is likely to be diluted it can still be dangerous. If you or anyone you know has been in contact with floodwater and has an upset stomach they should seek medical advice. Always contact your Doctor if you become ill after swallowing contaminated water.
  • Always wash your hands with soap and clean water after being in contact with flood water especially before eating or preparing food.
  • Don't allow children to play in floodwater and make sure they wash their hands frequently especially before meals.
  • Help for vulnerable and elderly people returning to their houses is available from Social Services at Derbyshire County Council - call 01629 533190 for assistance.

If any of your property is damaged beyond repair throw it away. If you think it can be salvaged and clean make sure you use lots of hot soapy water and disinfectant - this includes on children's toys. Don't use any electrical equipment that has been in the water unless it has been checked by a fully qualified electrician.
