Sewage flooding

In times of extremely intense rainfall, the flood drainage system may become overwhelmed and the water may find its way into the sewers. This can result in sewage flooding, whereby flood water is contaminated with sewage, which can be hazardous to health if not avoided and managed carefully.

Contact your GP immediately or call NHS 111 if you display any symptoms such as diarrhoea or vomiting after a flood.

Whilst contaminated flood water can be hazardous to health, following basic hygiene procedures and these instructions will make it unlikely for you to be at any increased health risk from sewage flooding:

  • wash hands and disinfect footwear after any contact with the sewage
  • keep children and pets out of any area affected by sewage flooding
  • whilst cleaning up after flooding, protect cuts and grazes with waterproof dressings and wear protective clothing such as rubber gloves
  • don't eat any fruit or vegetables growing in the garden if it has flooded, and don't plant any more for at least 6 months after sewer flooding. In the 6 months after this period you can plant new crops, provided that you don't harvest them for at least two months
